LP62S1664C Series
Preliminary
64K X 16 BIT LOW VOLTAGE CMOS SRAM
Features
General Description
n Operating voltage: 2.7V to 3.6V
n Access times: 55/70 ns (max.)
n Current:
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
LP62S1664C-55 series: Operating: 50mA (max.)
performance CMOS process.
Standby:
LP62S1664C-70 series: Operating: 40mA (max.)
Standby: 5mA (max.)
5mA (max.)
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.
n Extended operating temperature range : -40°C to 85°C
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.
