flow-through mode. echo clocks are not supported in flow-through mode and the dll must be disabled. flow-through mode is selected by the ftsel pin. strapping this pin high selects pipelined mode. strapping this pin low selects flow-through mode. dll the fullflex familes of devices have an on-chip dll. enabling the dll reduces the cl ock to data valid (t cd ) time allowing more set-up time for the receiv ing device. for operation below 100 mhz, the dll must be disabled. this is selectable by strapping lowspd low. whenever the operating frequency is altered beyond the clock input cycle to cycle jitter spec, the dll is required to be reset followed by 1024 clocks before any valid operation. lowspd pins can be used to reset the dll(s) for a single port independent of all other circuitry. mrst can be used to reset all dlls on the chip, for information on dll lock and reset time, please see the master reset section below. echo clocking as the speed of data increases, on-board delays caused by parasitics make providing accu rate clock trees extremely difficult. to counter this problem, the fullflex families incor- porate echo clocks. echo clo cks are enabled on a per port basis. the dual-port receives input clocks that are used to clock in the address and control signals for a read operation. the dual-port retransmits the inpu t clocks relative to the data output. the buffered clocks ar e provided on the cq1/cq1 and cq0/cq0 outputs. each port has a pair of echo clocks. each clock is associated with half the data bits. the output clock will match the corresponding ports i/o configuration. to enable echo clock outputs, tie cqen high. to disable echo clock outputs, tie cqen low. deterministic access control deterministic access control is provided for ease of design. the circuitry detects when both ports are accessing the same location and provides an external busy flag to the port on which data may be corrupted. the collision detection logic saves the address in conflict (busy address) to a readable register. in the case of multiple collisions, the first busy address will be written to the busy address register. if both ports are accessing the sa me location at the same time and only one port is doing a write, if t ccs is met, then the data being written to and read from the address is valid data. for example, if the right port is re ading and the left port is writing and the left ports clock meets t ccs , then the data being read from the address by the right port will be the old data. in the same case, if the righ t ports clock meets t ccs , then the data being read out of the address from the right port will be the new data. in the above case, if t ccs is violated by the either ports clock with respect to the other port and the right port gets the external busy flag, the data from the right port is corrupted. table 4 shows the t ccs timing that must be met to guarantee the data. table 5 shows that, in the case of the left port writing and the right port reading, when an external busy flag is asserted on the right port, the data read out of the device will not be guaranteed. the value in the busy address register can be read back to the address lines. the required input control signals for this function are shown in table 8 . the value in the busy address register will be read out to the address lines t ca after the same amount of latency as a data read operation. after an initial address match, the busy flag is asserted and the address under contention is saved in the busy address register. all following address matches cause the busy flag to be generated, however, none of the addresses are saved into the busy address register. once a busy readback is performed, the address of the first match that happens at least two clocks cycles after the busy readback is saved into the busy address register. table 3. data pin assignment be pin name data pin name be [7] dq[71:63] be [6] dq[62:54] be [5] dq[53:45] be

the on-board traces. the impedance is set for all outputs except jtag and is done on a per port basis. to take advantage of the vim feature, connect a calibrating resistor (rq) that is five times the value of the intended line impedance from the zq pin to vss. the output impedance is then adjusted to account for drifts in supply voltage and temper- ature every 1024 clock cycles. if a port?s clock is suspended, the vim circuit will retain its last setting until the clock is restarted. on restart, it will t hen resume periodic adjustment. in the case of a significant change in device temperature or supply voltage, recalibration will happen every 1024 clock cycles. a master reset will in itialize the vim circuitry. ta ble 6 shows the vim parameters and table 7 describes the vim operation modes. in order to disable vim, the zq pin must be connected to vddio of the relative supply for the i/os before a master reset. address counter and mask register operations [1] each port of the fullflex family contains a programmable burst address counter. the burst counter contains four registers: a counter register, a mask register, a mirror register, and a busy address register. the counter register contains the address used to access the ram array. it is changed only by the master reset (mrst ), counter reset, counter load, retransmit, and counter increment operations. the mask register value affects the counter increment and counter reset operations by preventing the corresponding bits of the counter register from changing. it also affects the counter interrupt output (cntint ). the mask register is only changed by mask reset, mask load, and mrst . the mask load operation loads the value of the address bus into the mask register. the mask regi ster defines the counting range of the counter register. the mask register is divided into two or three consecutive regions. zero or more ?0s? define the masked region and one or more ?1s? define the unmasked portion of the counter register . the counter register may only be divided into up to three regions. the region containing the least significant bits must be no more than two ?0s?. bits one and zero may be ?10? respectively, masking the least signif- icant counter bit and causing th e counter to increment by two instead of one. if bits one and zero are ?00?, the two least significant bits are masked and the counter will increment by four instead of one. for example, in the case of a 256kx72 table 5. deterministic access control logic left port right port left clock right clock busy l busy r

003fc divides the mask register into three regions. with bit 0 being the least significant bit and bit 17 being t he most significant bit, the two least significant bits are masked, the next eight bits are unmasked, and the remaining bits are masked. the mirror register is used to reload the counter register on retransmit operations (see ?retransmit? below) and wrap functions (see ?counter increment? below). the last value loaded into the counter register is stored in the mirror register. the mirror register is only changed by master reset (mrst ), counter reset, and counter load. table 8 summarizes the operations of these registers and the required input control signals. all signals except mrst are synchronized to the ports clock. counter load operation [1] the address counter and mirror registers are both loaded with the address value presented on the address lines. this value ranges from 0 to 1fffff. mask load operation [1] the mask register is loaded with the address value presented on the address bus. this value ranges from 0 to 1fffff though not all values permit co rrect increment operations. permitted values are in the form of 2 n ?1, 2 n ?2, or 2 n ?4. the counter register can only be segmented in up to three regions. from the most significant bit to the least significant bit, permitted values have zero or more ?0s?, one or more ?1s?, and the least significant two bits can be ?11?, ?10?, or ?00?. thus 1ffffe, 07ffff, and 003ffc are permitted values but 02ffff, 003ffa, and 07ffe4 are not. counter readback operation the internal value of the counter register can be read out on the address lines. the address will be valid t ca after the selected number of latency cycles configured by ftsel . the data bus (dq) is tri-stated on the cycle that the address is presented on the address lines. figure 3 shows a block diagram of this logic. mask readback operation the internal value of the mask register can be read out on the address lines. the address will be valid t ca after the selected number of latency cycles configured by ftsel . the data bus (dq) is tri-stated on the cycle t hat the address is presented on the address lines. figure 3 shows a block diagram of the operation. counter reset operation all unmasked bits of the counter and mirror registers are reset to ?0?. all masked bits remain unchanged. a mask reset followed by a counter reset will reset the counter and mirror registers to 00000. mask reset operation the mask register is reset to all ?1s?, which unmasks every bit of the burst counter. fullflex document #: 38-06082 rev. *g

initially loaded with an external address, the counter can inte rnally increment the address value and address the entire memory array. only the unmasked bits of the counter register are incremented. in order for a counter bit to change, the corresponding bit in the mask register must be ?1?. if the two least significant bits of the mask register are ?11?, the burst counter will increment by one. if the two least significant bits are ?10?, the burst counter will increment by two, and if they are ?00?, the burst counter will increment by four. if all unma sked counter bits are incre- mented to ?1? and wrp is deasserted, the next increment will wrap the counter back to the initially loaded value. the cycle before the increment that results in all unmasked counter bits to become ?1s?, a counte r interrupt flag (cntint ) is asserted if the counter is incremented again. this increment will cause the counter to reach its maximum value and the next increment will return the counter register to its initial value that was stored in the mirror register if wrp is deasserted. if wrp is asserted, the unmasked portion of the counter is filled with ?0? instead. the example shown in figure 4 shows an example of the cydd36s18v18 device with the mask register loaded with a mask value of 00007f unmasking the seven least significant bits. setting the mask register to this value allows the counter to access the entire memory space. the address counter is then loaded with an initial value of 000005 assuming wrp is deasserted. the masked bits, the seventh address through the twenty-first address, do not increment in an increment operation. the counter address will start at address 000005 and will increment its internal address value until it reaches the mask register value of 00007f. the counter wraps around the memory block to location 000005 at the next count. cntint is issued when the counter reaches the maximum ?1 count. hold operation the value of all three registers can be constantly maintained unchanged for an unlimited number of clock cycles. such operation is useful in applic ations where wait states are needed, or when address is available a few cycles ahead of data in a shared bus interface. retransmit retransmit allows repeated access to the same block of memory without the need to re load the initial address. an internal mirror register stores the address counter value last loaded. while ret is asserted low, the counter will continue to wrap back to the value in the mirror register independent of the state of wrp . counter interrupt the counter interrupt (cntint ) is asserted low one clock cycle before an increment operation that results in the unmasked portion of the counter register being all ?1s?. it is deasserted by counter reset, counter load, mask reset, mask load, and mrst . counting by two when the two least significant bits of the mask register are ?10,? the counter increments by two. counting by four when the two least significant bits of the mask register are ?00?, the counter increments by four. mailbox interrupts the upper two memory locations can be used for message passing and permit communications between ports. table 9 shows the interrupt operation for both ports. the highest memory location is the mailbox for the right port and the maximum address ? 1 is the mailbox for the left port. when one port writes to the other port?s mailbox, the int flag of the port that the mailbox belongs to is asserted low. the int flag remains asserted until the mailbox location is read by the other port. when a port reads its mailbox, the int flag is deasserted high after one cycle of latency with respect to the input clock of the port to which the mailbox belongs and is independent of oe . table 9 shows that in or der to set the int r flag, a write operation by the left port to address 1fffff will assert int r low. a valid read of the 1fffff location by the right port will reset int r high after one cycle of la tency with respect to the right port?s clock. at least one byte enable has to be activated to set or reset the mailbox interrupt. fullflex document #: 38-06082 rev. *g page 15 of

levels. the mrst can be asserted asynchronously to the clocks and must remain asserted for at least t rs . once asserted mrst deasserts ready , initializes the internal burst counters, internal mirror re gisters, and internal busy addresses to zero, and initializes the internal mask register to all ?1s?. all mailbox interrupts (int ), busy address outputs (busy ), and burst counter interrupts (cntint ) are deasserted upon master reset. additionally, mrst must not be released until all power supplies including vref are fully ramped, all port cl ocks and mode select inputs (lowspd , zq, cqen, ddron, ftsel , and portstd) are valid and stable. this begins calibration of the dll and vim circuits. ready will be asserted within 1024 clock cycles. ready is a wired or capable output with a strong pull-up and weak pull-down. up to four outputs may be connected together. for faster pull-down of the signal, connect a 250 ohm resistor to vss. if the dll and vim circuits are disabled for a port, the port will be operational within five cl ock cycles. however, the ready will be asserted within 160 clock cycles. ieee 1149.1 serial boundary scan (jtag) the fullflex families incorporate an ieee 1149.1 serial boundary scan test access port (tap). the tap operates using jedec-standard 3.3v or 2. 5v i/o logic levels depending on the vttl power supply. it is composed of four input connections and one output connection required by the test logic defined by the standard. notes: 19. ce is internal signal. ce = low if ce 0 = low and ce 1 = high. for a single read operation, ce only
