spartan-3an fpga family: introduction and ordering information ds557 (v4.1) april 1, 2011 www.xilinx.com product specification 3 architectural overview the spartan-3an fpga architectu re is compatible with that of the spartan-3a fpga. the architecture consists of five fundamental programmable functional elements: ? configurable logic blocks (clbs) contain flexible look-up tables (luts) that implement logic plus storage elements used as flip-flops or latches. ? input/output blocks (iobs) control the flow of data between the i/o pins and the internal logic of the device. iobs support bidirectional data flow plus 3-state operation. they support a variety of signal standards, including several high-performance differential standards. double data-rate (ddr) registers are included. ? block ram provides data storage in the form of 18-kbit dual-port blocks. ? multiplier blocks accept two 18-bit binary numbers as inputs and calculate the product. ? digital clock manager (dcm) blocks provide self-calibrating, fully digital solutions for distributing, delaying, multiplying, dividing, and phase-shifting clock signals. these elements are organized as shown in figure 1 . a dual ring of staggered iobs surrounds a regular array of clbs. each device has two columns of block ram except for the xc3s50an, which has one column. each ram column consists of several 18-kbit ram blocks. each block ram is associated with a dedicated multiplier. the dcms are positioned in the center with two at the top and two at the bottom of the device. the xc3s50an has dcms only at the top, while the xc3s700an and xc3s1400an add two dcms in the middle of the two columns of block ram and multipliers. the spartan-3an fpga features a rich network of traces that interconnect all five functional elements, transmitting signals among them. each functional element has an associated switch matrix that permits multiple connections to the routing. x-ref target - figure 1 figure 1: spartan-3an family architecture clb block ram multiplier dcm iobs iobs ds557-1_01_122006 iobs iobs dcm block ram / multiplier dcm clbs iobs ob s d c m notes: 1. the xc3s700an and xc3s1400an have two additional dcms on both the left and right sides as indicated by the dashed lines. the xc3s50an has only two dcms at the top and only one block ram/multiplier column.
spartan-3an fpga family: introduction and ordering information ds557 (v4.1) april 1, 2011 www.xilinx.com product specification 4 configuration spartan-3an fpgas are programmed by loading configuration data into robust, reprogrammable, static cmos configuration latches (ccl s) that collectively control all functional elements and routing resources. the fpga?s configuration data is stored on-chip in nonvolatile flash memory, or externally in a prom or some other nonvolatile medium, either on or off the board. after applying power, the configuration data is written to the fpga using any of seven different modes: ? configure from internal spi flash memory ( figure 2 ) ? completely self-contained ? reduced board space ? easy-to-use config uration interface ? master serial from a xilinx platform flash prom ? serial peripheral interface (spi) from an external industry-standard spi serial flash ? byte peripheral interface (bpi) up from an industry-standard x8 or x8/x16 parallel nor flash ? slave serial, typically downloaded from a processor ? slave parallel, typically downloaded from a processor ? boundary-scan (jtag), typically downloaded from a processor or system tester the multiboot feature stores mu ltiple configur ation files in the on-chip flash, providing extended life with field upgrades. multiboot also supports multiple system solutions with a single board to minimize inventory and simplify the addition of new features, even in the field. flexibility is maintained to do additional multiboot configurations via the external configuration method. the spartan-3an device authentication protocol prevents cloning. design cloning, unauthorized overbuilding, and complete reverse engineering have driven device security requirements to higher and higher levels. authentication moves the security from bitstream protection to the next generation of design-level security protecting both the design and embedded microcode. the authentication algorithm is entirely user defined, implemented using fpga logic. every product, generation, or design can have a different algorithm and functionality to enhance security. in-system flash memory each spartan-3an fpga contains abundant integrated spi serial flash memory, shown in ta b l e 3 , used primarily to store the fpga?s configuration bitstream. however, the flash memory array is large enough to store at least two multiboot fpga configuration bitstreams or nonvolatile data required by the fpga application, such as code-shadowed microblaze processor applications. after configuration, the fpga design has full access to the in-system flash memory via an internal spi interface; the control logic is implemented wi th fpga logic. additionally, the fpga application itself can store nonvolatile data or provide live, in-system flash updates. the spartan-3an device in-system flash memory supports leading-edge serial flash features. ? small page size (264 or 528 bytes) simplifies nonvolatile data storage ? randomly accessible, byte addressable ? up to 66 mhz serial data transfers ? sram page buffers ? read flash data while programming another flash page ? eeprom-like byte write functionality ? two buffers in most devices, one in xc3s50an ? page, block, and sector erase x-ref target - figure 2 figure 2: spartan-3an fpga configuration interface from internal spi flash memory m2 m1 m0 vccaux init_b done s p a rt a n- 3 an fpga ?0 ? ?1 ? ?1 ? 3 . 3 v config u re from intern a l fl as h memory indic a te s when config u r a tion i s fini s hed d s 557-1_06_0 8 2 8 10 ta b l e 3 : spartan-3an device in-system flash memory part number total flash memory (bits) fpga bitstream (bits) additional flash memory (bits) (1) xc3s50an 1,081,344 437,312 642,048 xc3s200an 4,325,376 1,196,128 3,127,872 xc3s400an 4,325,376 1,886,560 2,437,248 xc3s700an 8,650,752 2,732,640 5,917,824 xc3s1400an 17,301,504 4,755,296 12,545,280 notes: 1. aligned to next available page location.

spartan-3an fpga family: dc and switching characteristics ds557 (v4.1) april 1, 2011 www.xilinx.com product specification 43 using ibis models to simulate load conditions in application ibis models permit the most accurate prediction of timing delays for a given application. the parameters found in the ibis model (v ref , r ref , and v meas ) correspond directly with the parameters used in ta b l e 3 0 (v t , r t , and v m ). do not confuse v ref (the termination voltage) from the ibis model with v ref (the input-switching threshold) from the table. a fourth parameter, c ref , is always zero. the four parameters describe all relevant output test conditions. ibis models are found in the xilinx development software as well as at the following link: www.xilinx.com/support/download/index.htm delays for a given application are simulated according to its specific load conditions as follows: 1. simulate the desired signal standard with the output driver connected to the test setup shown in figure 11 . use parameter values v t , r t , and v m from ta bl e 3 0 . c ref is zero. 2. record the time to v m . 3. simulate the same signal standard with the output driver connected to the pcb trace with load. use the appropriate ibis model (including v ref , r ref , c ref , and v meas values) or capacitive value to represent the load. 4. record the time to v meas . 5. compare the results of steps 2 and 4. add (or subtract) the increase (or decrease) in delay to (or from) the appropriate output standard adjustment ( ta b l e 2 9 ) to yield the worst-case delay of the pcb trace. simultaneously switching output guidelines this section provides guidelines for the recommended maximum allowable number of simultaneous switching outputs (ssos). these guidelines describe the maximum number of user i/o pins of a given output signal standard that should simultaneously swit ch in the same direction, while maintaining a safe level of switching noise. meeting these guidelines for the stated test conditions ensures that the fpga operates free from the adverse effects of ground and power bounce. ground or power bounce occurs when a large number of outputs simultaneously switch in the same direction. the output drive transistors all conduct current to a common voltage rail. low-to-high tr ansitions conduct to the v cco rail; high-to-low transitions conduct to the gnd rail. the resulting cumulative current transient induces a voltage difference across the inductance that exists between the die pad and the power supply or ground return. the inductance is associated with bonding wires, the package lead frame, and any other signal routing inside the package. other variables contribute to sso noise levels, including stray inductance on the pcb as well as capacitive loading at receivers. any sso-induced voltage consequently affects internal switching noise margins and ultimately signal quality. ta b l e 3 1 and ta bl e 3 2 provide the essential sso guidelines. for each device/package combination, ta b l e 3 1 provides the number of equivalent v cco /gnd pairs. the equivalent number of pairs is based on characterization and may not match the physical number of pairs. for each output signal standard and drive strength, ta b l e 3 2 recommends the maximum number of ssos, switching in the same direction, allowed per v cco /gnd pair within an i/o bank. the guidelines in ta bl e 3 2 are categorized by package style, slew rate, and output drive current. furthermore, the number of ssos is specified by i/o bank. generally, the left and right i/o banks (banks 1 and 3) support higher output drive current. multiply the appropriate numbers from ta bl e 3 1 and ta b l e 3 2 to calculate the maximum number of ssos allowed within an i/o bank. exceeding these sso guidelines might result in increased power or ground bounce, degraded signal integrity, or increased system jitter. sso max /io bank = ta b l e 3 1 x ta bl e 3 2 the recommended maximum sso values assumes that the fpga is soldered on the printed circuit board and that the board uses sound design practices. the sso values do not apply for fpgas mounted in sockets, due to the lead inductance introduced by the socket. the number of ssos allowed for quad-flat packages (tq) is lower than for ball grid array packages (fg) due to the larger lead inductance of the quad-flat packages. ball grid array packages are recommended for applications with a large number of simultaneously switching outputs. ta b l e 3 1 : equivalent v cco /gnd pairs per bank device package style tqg144 ftg256 fgg400 fgg484 fgg676 xc3s50an 2 3 ? ? ? xc3s200an ?4 ? ? ? xc3s400an ?45 ? ? xc3s700an ? ? ?5 ? xc3s1400an ? ? ?69

spartan-3an fpga family: dc and switching characteristics ds557 (v4.1) april 1, 2011 www.xilinx.com product specification 52 digital clock manager (dcm) timing for specification purposes, the dcm consists of three key components: the delay-locked loop (dll), the digital frequency synthesizer (dfs), and the phase shifter (ps). aspects of dll operation play a role in all dcm applications. all such applicat ions inevitably use the clkin and the clkfb inputs connected to either the clk0 or the clk2x feedback, respectively. thus, specifications in the dll tables ( ta bl e 3 9 and ta bl e 4 0 ) apply to any application that only employs the dll component. when the dfs and/or the ps components are used together with the dll, then the specifications listed in the dfs and ps tables ( ta bl e 4 1 through ta b l e 4 4 ) supersede any corresponding ones in the dll tables. dll specifications that do not change with the addition of dfs or ps functions are presented in ta bl e 3 9 and ta bl e 4 0 . period jitter and cycle-cycle jitter are two of many different ways of specifying clock jitter. both specifications describe statistical variation from a mean value. period jitter is the worst-case deviation from the ideal clock period over a collection of millions of samples. in a histogram of period jitter, the mean value is the clock period. cycle-cycle jitter is the worst-ca se difference in clock period between adjacent clock cycles in the collection of clock periods sampled. in a histogram of cycle-cycle jitter, the mean value is zero. spread spectrum dcms accept typical spread spectrum clocks as long as they meet the input requir ements. the dll will track the frequency changes created by th e spread spectrum clock to drive the global clocks to the fpga logic. see xapp469 : spread-spectrum clocking reception for displays for details. delay-locked loop (dll) ta bl e 3 9 : recommended operating conditions for the dll symbol description speed grade units -5 -4 min max min max input frequency ranges f clkin clkin_freq_dll frequency of the clkin clock input 5 (2) 280 (3) 5 (2) 250 (3) mhz input pulse requirements clkin_pulse clkin pulse width as a percentage of the clkin period f clkin < 150 mhz 40% 60% 40% 60% % f clkin > 150 mhz 45% 55% 45% 55% % input clock jitter tolerance and delay path variation (4) clkin_cyc_jitt_dll _lf cycle-to-cycle jitter at the clkin input f clkin < 150 mhz ?300 ?300ps clkin_cyc_jitt_dll_hf f clkin > 150 mhz ?150 ?150ps clkin_per_jitt_dll period jitter at the clkin input ?1 ?1ns clkfb_delay_var_ext allowable variation of off-chip feedback delay from the dcm output to the clkfb input ?1 ?1ns notes: 1. dll specifications apply when any of the dll outputs (clk0, clk90, clk180, clk270, clk2x, clk2x180, or clkdv) are in use. 2. the dfs, when operating independently of the dll, supports lower fclkin frequencies. see ta b l e 4 1 . 3. the clkin_divide_by_2 attribute can be used to increase the effective input frequency range up to f bufg . when set to true, clkin_divide_by_2 divides the incoming clock frequency by two as it enters the dcm. 4. clkin input jitter beyond these limits might cause the dcm to lose lock. 5. the dcm specifications are guaranteed when both adjacent dcms are locked.
