LP62E16128A-I Series
128K X 16 BIT LOW VOLTAGE CMOS SRAM
Features
„
„
„
„
„ Operating voltage: 1.65V to 2.2V
„ Access times: 70 ns (max.)
„ Current:
Very low power version: Operating: 25mA (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: 1.2V (min.)
Available in 44-pin TSOP and 48-ball CSP (6 x 8mm)
packages
„ All Pb-free (Lead-free) products are RoHS compliant
General Description
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 1.2V.
The LP62E16128A-I is a low operating current 2,097,152bit static random access memory organized as 131,072
words by 16 bits and operates on low power voltage from
1.65V to 2.2V. 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.

Notes: 1. tAS is measured from the address valid to the beginning of Write.
2. A Write occurs during the overlap (tWP, tBW) of a low CE , WE and ( HB and , or LB ).
3. tWR is measured from the earliest of CE or WE or ( HB and , or LB ) going high to the end of the Write cycle.
4. OE level is high or low.
5. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.
