Access times: 55/70 ns (max.)
Current:
Very low power version: Operating:
55ns 40mA (max.)
70ns 35mA (max.)
Standby: 10µA (max.)
Full static operation, no clock or refreshing required
All inputs and outputs are directly TTL-compatible
Common I/O using three-state output
Data retention voltage: 2V (min.)
Available in 44-pin TSOP and 48-ball CSP (6 x 8 mm)
packages
General Description
The LP62S16128B-T is a low operating current 2,097,152-
bit static random access memory organized as 131,072
words by 16 bits and operates on low power 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.
