P4C1048L PYRAMID [Pyramid Semiconductor Corporation], P4C1048L Datasheet - Page 6

• Manufacturer Part Number: P4C1048L
• Description: LOW POWER 512K x 8 CMOS STATIC RAM
• Manufacturer: PYRAMID [Pyramid Semiconductor Corporation]

Notes:
6. CE and WE are LOW for WRITE cycle.
7. OE is LOW for this WRITE cycle to show t
8. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high impedance state.
9. Write Cycle Time is measured from the last valid address to the first transitioning address.
