General Description
The LP62S4096E-I is a low operating current 4,194,304-bit
static random access memory organized as 524,288
words by 8 bits and operates on a low power supply range:
2.7V to 3.3V. It is built using AMIC's high performance
CMOS process.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
Two chip enable inputs are provided for POWER-DOWN
and device enable and an output enable input is included
for easy interfacing.
Data retention is guaranteed at a power supply voltage as
low as 2V.
n CE2 pin for CSP package only
