DESCRIPTION
The ISSI IS61C256AL is a very high-speed, low power,
32,768 word by 8-bit static RAMs. It is fabricated using
ISSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields access times as fast as 10 ns maximum.
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down to 150 µW (typical) with CMOS input levels.
Easy memory expansion is provided by using an active
LOW Chip Enable (CE) input and an active LOW Output
Enable (OE) input. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IS61C256AL is pin compatible with other 32Kx8 SRAMs
and are available in 28-pin SOJ and TSOP (Type I)
packages.
