LP62S16256G-I Series
Preliminary
256K X 16 BIT LOW VOLTAGE CMOS SRAM
Features
General Description
Operating voltage: 2.7V to 3.6V
Access times: 55ns / 70ns (max.)
Current:
The LP62S16256G-I is a low operating current 4,194,304-bit
static random access memory organized as 262,144 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.
Very low power version: Operating: 40mA (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: 2.0V (min.)
Data retention is guaranteed at a power supply voltage as low
as 2.0V.
Available in 44-pin TSOP and 48-ball CSP (6× 8mm)
packages
All Pb-free (Lead-free) products are RoHS compliant

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.
