2 / 17 page LP62S2048A-I Series Preliminary 256K X 8 BIT LOW VOLTAGE CMOS SRAM PRELIMINARY (June, 2002, Version 0.0) 2 AMIC Technology, Inc. Features General Description n Power supply range: 2.7V to 3.3V n Access times: 55/70 ns (max.) n Current: Very low power version: Operating: 55ns: 25mA (max.) 70ns: 20mA (max.) Standby: 10 µA (max.) 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, TSSOP (8X13.4mm) and 36-pin CSP packages The LP62S2048A-I is a low operating current 2,097,152-bit static random access memory organized as 262,144 words by 8 bits and operates on a low power supply range: 2.7V to 3.3V. 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. Two chip enable inputs are provided for POWER-DOWN and device enable and an output enable input is included for easy interfacing. Data retention is guaranteed at a power supply voltage as low as 2V.
