When it is connected to ground, the (x8) organization is selected. Instructions, addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a High-Z state except when reading data from the device, or when checking the Ready/ Busy status during a programming operation. The Ready/Busy status can be verified during an Erase/ Write operation by polling the DO pin; DO low indicates that programming is still in progress, while DO high indicates the device is ready. DO will enter the High-Z state on the falling edge of CS. It is possible to connect the Data In and Data Out pins together. However, with this configuration it is possible for a "bus conflict" to occur during the "dummy zero" that precedes the read operation, if A0 is a logic high level. Under such a condition the voltage level seen at Data Out is undefined and will depend upon the relative impedances of Data Out and the signal source driving A0. The higher the current sourcing capability of A0, the higher the voltage at the Data Out pin. In order to limit this current, a resistor should be connected between DI and DO. 2.3 Data Protection 2.1 START Condition The Start bit is detected by the device if CS and DI are both high with respect to the positive edge of CLK for the first time. Before a Start condition is detected, CS, CLK and DI may change in any combination (except to that of a Start condition), without resulting in any device operation (Read, Write, Erase, EWEN, EWDS, ERAL or WRAL). As soon as CS is high, the device is no longer in Standby mode. An instruction following a Start condition will only be executed if the required opcode, address and data bits for any particular instruction are clocked in. Note: When preparing to transmit an instruction, either the CLK or DI signal levels must be at a logic low as CS is toggled active high. All modes of operation are inhibited when VCC is below a typical voltage of 1.5V for `93AA' and `93LC' devices or 3.8V for `93C' devices. The EWEN and EWDS commands give additional protection against accidentally programming during normal operation. Note: For added protection, an EWDS command should be performed after every write operation and an external 10 k pull-down protection resistor should be added to the CS pin. After power-up, the device is automatically in the EWDS mode. Therefore, an EWEN instruction must be performed before the initial ERASE or WRITE instruction can be executed.

CS is brought low following the loading of the last address bit. This falling edge of the CS pin initiates the self-timed programming cycle, except on `93C' devices where the rising edge of CLK before the last address bit initiates the write cycle. The DO pin indicates the Ready/Busy status of the device if CS is brought high after a minimum of 250 ns low (TCSL). DO at logical `0' indicates that programming is still in progress. DO at logical `1' indicates that the register at the specified address has been erased and the device is ready for another instruction. Note: After the Erase cycle is complete, issuing a Start bit and then taking CS low will clear the Ready/Busy status from DO.

DS21794E-page 7 93AA56A/B/C, 93LC56A/B/C, 93C56A/B/C 2.5 Erase All (ERAL) The Erase All (ERAL) instruction will erase the entire memory array to the logical `1' state. The ERAL cycle is identical to the erase cycle, except for the different opcode. The ERAL cycle is completely self-timed and commences at the falling edge of the CS, except on `93C' devices where the rising edge of CLK before the last data bit initiates the write cycle. Clocking of the CLK pin is not necessary after the device has entered the ERAL cycle. The DO pin indicates the Ready/Busy status of the device, if CS is brought high after a minimum of 250 ns low (TCSL). Note: After the ERAL command is complete, issuing a Start bit and then taking CS low will clear the Ready/Busy status from DO. VCC must be 4.5V for proper operation of ERAL.

To protect against accidental data disturbance, the EWDS instruction can be used to disable all erase/write functions and should follow all programming operations. Execution of a READ instruction is independent of both the EWEN and EWDS instructions. The 93XX56A/B/C powers up in the Erase/Write Disable (EWDS) state. All programming modes must be preceded by an Erase/Write Enable (EWEN) instruction.

A dummy zero bit precedes the 8-bit (if ORG pin is low or A-Version devices) or 16-bit (if ORG pin is high or B-version devices) output string. The output data bits will toggle on the rising edge of the CLK and are stable after the specified time delay (TPD). Sequential read is possible when CS is held high. The memory data will automatically cycle to the next register and output sequentially.

DS21794E-page 9 93AA56A/B/C, 93LC56A/B/C, 93C56A/B/C 2.8 Write The WRITE instruction is followed by 8 bits (if ORG is low or A-version devices) or 16 bits (if ORG pin is high or B-version devices) of data which are written into the specified address. For 93AA56A/B/C and 93LC56A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle. For 93C56A/B/C devices, the selftimed auto-erase and programming cycle is initiated by the rising edge of CLK on the last data bit. The DO pin indicates the Ready/Busy status of the device, if CS is brought high after a minimum of 250 ns low (TCSL). DO at logical `0' indicates that programming is still in progress. DO at logical `1' indicates that the register at the specified address has been written with the data specified and the device is ready for another instruction. Note: After the Write cycle is complete, issuing a Start bit and then taking CS low will clear the Ready/Busy status from DO.

For 93AA56A/B/C and 93LC56A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle. For 93C56A/B/C devices, the self-timed autoerase and programming cycle is initiated by the rising edge of CLK on the last data bit. Clocking of the CLK pin is not necessary after the device has entered the WRAL cycle. The WRAL command does include an automatic ERAL cycle for the device. Therefore, the WRAL instruction does not require an ERAL instruction, but the chip must be in the EWEN status. The DO pin indicates the Ready/Busy status of the device if CS is brought high after a minimum of 250 ns low (TCSL). Note: After the Write All cycle is complete, issuing a Start bit and then taking CS low will clear the Ready/Busy status from DO. VCC must be 4.5V for proper operation of WRAL.

However, a programming cycle which is already in progress will be completed, regardless of the Chip Select (CS) input signal. If CS is brought low during a program cycle, the device will go into Standby mode as soon as the programming cycle is completed. CS must be low for 250 ns minimum (TCSL) between consecutive instructions. If CS is low, the internal control logic is held in a Reset status. data bits before an instruction is executed. CLK and DI then become "don't care" inputs waiting for a new Start condition to be detected. 3.3 Data In (DI) Data In (DI) is used to clock in a Start bit, opcode, address and data synchronously with the CLK input. 3.4 Data Out (DO) 3.2 Serial Clock (CLK) Data Out (DO) is used in the Read mode to output data synchronously with the CLK input (TPD after the positive edge of CLK). This pin also provides Ready/Busy status information during erase and write cycles. Ready/Busy status information is available on the DO pin if CS is brought high after being low for minimum Chip Select low time (TCSL) and an erase or write operation has been initiated. The Status signal is not available on DO, if CS is held low during the entire erase or write cycle. In this case, DO is in the High-Z mode. If status is checked after the erase/write cycle, the data line will be high to indicate the device is ready. Note: After a programming cycle is complete, issuing a Start bit and then taking CS low will clear the Ready/Busy status from DO. The Serial Clock is used to synchronize the communication between a master device and the 93XX series device. Opcodes, address and data bits are clocked in on the positive edge of CLK. Data bits are also clocked out on the positive edge of CLK. CLK can be stopped anywhere in the transmission sequence (at high or low level) and can be continued anytime with respect to Clock High Time (TCKH) and Clock Low Time (TCKL). This gives the controlling master freedom in preparing opcode, address and data. CLK is a "don't care" if CS is low (device deselected). If CS is high, but the Start condition has not been detected (DI = 0), any number of clock cycles can be received by the device without changing its status (i.e., waiting for a Start condition). CLK cycles are not required during the self-timed write (i.e., auto erase/write) cycle. After detection of a Start condition the specified number of clock cycles (respectively low-to-high transitions of CLK) must be provided. These clock cycles are required to clock in all required opcode, address and 3.5 Organization (ORG) When the ORG pin is connected to VCC or Logic HI, the (x16) memory organization is selected. When the ORG pin is tied to VSS or Logic LO, the (x8) memory organization is selected.
