• Manufacturer Part Number: CY7C1049-20VM
• Description: 512K x 8 Static RAM
• Manufacturer: CYPRESS [Cypress Semiconductor]

Switching Waveforms
Write Cycle No. 1 (CE Controlled)
Write Cycle No. 2 (WE Controlled, OE HIGH During Write)
Notes:
Document #: 38-05063 Rev. **
14. Data I/O is high impedance if OE = V
15. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
16. During this period the I/Os are in the output state and input signals should not be applied.
