• Manufacturer Part Number: IDT71V016SA
• Description: 3.3v Cmos Static Ram 1 Meg 64k X 16-bit
• Manufacturer: Integrated Device Technology

Timing Waveform of Read Cycle No. 2
NOTES:
1. WE is HIGH for Read Cycle.
2. Address must be valid prior to or coincident with the later of CS, BHE, or BLE transition LOW; otherwise t
3. Transition is measured ±200mV from steady state.
Timing Waveform of Write Cycle No. 1 (WE Controlled Timing)
NOTES:
1. A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE.
2. OE is continuously HIGH. If during a WE controlled write cycle OE is LOW, t
3. During this period, I/O pins are in the output state, and input signals must not be applied.
4. If the CS LOW or BHE and BLE LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. Transition is measured ±200mV from steady state.
