SS is driven low during this cycle, signaling that the SRAM should drive out the data. During consecutive read cycles where the address is the same, the data output must be held constant without any glitches. This characteristic is because the SRAM will be read by devices that will operate slower than the SRAM frequency and will require multiple SRAM cycles to perform a single read operation. Write(Store) Operation All addresses and SW are sampled on the clock rising edge. SW is low on the rising clock. Write data is sampled on the rising clock, one cycle after write address and SW have been sampled by the SRAM. SS will be driven low during the same cycle that the Address, SW and SW[a:d] are valid to signal that a valid operation is on the Address and Control Input. Pipelined write are supported. This is done by using write data buffers on the SRAM that capture the write addresses on one write cycle, and write the array on the next write cycle. The "next write cycle" can actually be many cycles away, broken by a series of read cycles. Byte writes are supported. The byte write signals SW[a:d] signal which 9-bit bytes will be writen. Timing of SW[a:d] is the same as the SW signal. Bypass Read Operation Since write data is not fully written into the array on first write cycle, there is a need to sense the address in case a future read is to be done from the location that has not been written yet. For this case, the address comparator check to see if the new read address is the same as the contents of the stored write address Latch. If the contents match, the read data must be supplied from the stored write data latch with standard read timing. If there is no match, the read data comes from the SRAM array. The bypassing of the SRAM array occurs on a byte by byte basis. If one byte is written and the other bytes are not, read data from the last written will have new byte data from the write data buffer and the other bytes from the SRAM array. Programmable Impedance Output Buffer Operation This HSTL Late Write SRAM has been designed with programmable impedance output buffers. The SRAMs output buffer impedance can be adjusted to match the system data bus impedance, by connecting a external resistor (RQ) between the ZQ pin of the SRAM and VSS. The value of RQ must be five times the value of the intended line impedance driven by the SRAM. For example, a 250Ω resistor will give an output buffer impedance of 50Ω. The allowable range of RQ is from 175Ω to 350Ω. Internal circuits evaluate and periodically adjust the output buffer impedance, as the impedance is affected by drifts in supply voltage and temperature. One evaluation occurs every 32 clock cycles, with each evaluation moving the output buffer impedance level only one step at a time toward the optimum level. Impedance updates occur when the SRAM is in High-Z state, and thus are triggered by write and deselect operations. Updates will also be triggered with G HIGH initiated High-Z state, providing the specified G setup and hold times are met. Impedance match is not instantaneous upon power-up. In order to guarantee optimum output driver impedance, the SRAM requires a minimum number of non-read cycles (1,024) after power-up. The output buffers can also be programmed in a minimum impedance configuration by connecting ZQ to VSS or VDDQ. Mode Control There are two mode control select pins (M1 and M2) used to set the proper read protocol. This SRAM supports single clock pipelined operating mode. For proper specified device operation, M1 must be connected to VSS and M2 must be connected to VDDQ. These mode pins must be set at power-up and must not change during device operation. Power-Up/Power-Down Supply Voltage Sequencing The following power-up supply voltage application is recommended: VSS, VDD, VDDQ, VREF, then VIN. VDD and VDDQ can be applied simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-up. The following power-down supply voltage removal sequence is recommended: VIN, VREF, VDDQ, VDD, VSS. VDD and VDDQ can be removed simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-down. Sleep Mode Sleep mode is a low power mode initiated by bringing the asynchronous ZZ pin high. During sleep mode, all other inputs are ignored and outputs are brought to a High-Impedance state. Sleep mode current and output High-Z are guaranteed after the specified sleep mode enable time. During sleep mode the memory array data content is preserved. Sleep mode must not be initiated until after all pending operations have completed, as any pending operation is not guaranteed to properly complete after sleep mode is initiated. Normal operations can be resumed by bringing the ZZ pin low, but only after the specified sleep mode recovery time. -6- Rev. 1.2 February 2007 K7P323674C K7P321874C 1Mx36 & 2Mx18 SRAM TRUTH TABLE K ZZ G SS SW SWa SWb SWc SWd DQa DQb DQc DQd Operation X H X X X X X X X Hi-Z Hi-Z Hi-Z Hi-Z Power Down Mode.

The package pads are monitored by the Serial Scan circuitry when in test mode. This is to support connectivity testing during manufacturing and system diagnostics. Internal data is not driven out of the SRAM under JTAG control. In conformance with IEEE 1149.1, the SRAM contains a TAP controller, Instruction Register, Bypass Register and ID register. The TAP controller has a standard 16-state machine that resets internally upon power-up, therefore, TRST signal is not required. It is possible to use this device without utilizing the TAP. To disable the TAP controller without interfacing with normal operation of the SRAM, TCK must be tied to VSS to preclude mid level input. TMS and TDI are designed so an undriven input will produce a response identical to the application of a logic 1, and may be left unconnected. But they may also be tied to VDD through a resistor. TDO should be left unconnected. JTAG Instruction Coding JTAG Block Diagram IR2 IR1 IR0 Instruction SRAM CORE M1 M2 TDI BYPASS Reg. TDO Identification Reg. Instruction Reg.
