Product Summary
The ISSI IS62C256AL-45ULI is a low power, 32,768 word by 8-bit CMOS static RAM. It is fabricated using ISSI’s high-performance, low power CMOS technology. When CE is HIGH (deselected), the IS62C256AL-45ULI assumes a standby mode at which the power dissipation can be reduced down to 150 μW (typical) at CMOS input levels. Easy memory expansion is provided by using an active LOW Chip Select (CE) input and an active LOW Output Enable (OE) input. The active LOW Write Enable (WE) of IS62C256AL-45ULI controls both writing and reading of the memory.
