General Description
The A62S7308B is a low operating current 1048,576-bit
static random access memory organized as 131,072
words by 8 bits and operates on a low power supply
voltage from 2.7V to 3.6V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
Pin Configurations
n SOP
n TSOP/(sTSOP)
(forward type)
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 Output enable and two chip enable inputs for easy
application
n Data retention voltage: 2V (min.)
n Available in 32-pin SOP, TSOP, sTSOP (8X
13.4mm) forward type and 36-ball Mini BGA (6X8)
packages
n Interfaces directly with 3.3V typ. logic chip
Two chip enable inputs are provided for power down and
a device enable and an output enable input are included
for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 2V.
