| LP62E16128A-I Series Preliminary Document Title 128K X 16 BIT LOW VOLTAGE CMOS SRAM Revision History Rev. No. 0.0 128K X 16 BIT LOW VOLTAGE CMOS SRAM History Initial issue Issue Date December 11, 2003 Remark Preliminary PRELIMINARY (December, 2003, Version 0.0) 1 AMIC Technology, Corp. LP62E16128A-I Series Preliminary Features Operating voltage: 1.65V to 2.2V Access times: 70 ns (max.) Current: Very low power version: Operating: 25mA (max.) Standby: 10A (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 128K X 16 BIT LOW VOLTAGE CMOS SRAM General Description 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. 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.
