• Manufacturer Part Number: 5962-3829409MXA
• Description: SRAM 64K Asynchronous 8K x 8 SRAM
• Manufacturer: IDT

Timing Waveform of Write Cycle No. 1 (WE Controlled Timing)
Timing Waveform of Write Cycle No. 2 (CS Controlled Timing)
NOTES:
1. A write occurs during the overlap of a LOW WE, a LOW CS
2. t
3. During this period, I/O pins are in the output state so that the input signals must not be applied.
4. If the CS
5. OE is continuously HIGH. If OE is LOW during a WE controlled write cycle, the write pulse width must be the larger of t
6. Transition is measured ±200mV from steady state.
