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.
CE2 pin for CSP package only
