for -LLI series

n Full static operation, no clock or refreshing required

n All inputs and outputs are directly TTL-compatible

n Common I/O using three-state output

n Data retention voltage: 2V (min.)

n Available in 44-pin TSOP and 48-ball Mini BGA (6X8)

packages.

The LP62S1664C is a low operating current 1,048,576-

bit static random access memory organized as 65,536

words by 16 bits and operates on low power supply

voltage from 2.7V to 3.6V. 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.

The chip enable input is provided for POWER-DOWN,

device enable. Two byte enable inputs and an output

enable input are included for easy interfacing.

Data retention is guaranteed at a power supply voltage

as low as 2V.
