2 / 14 page LP62S4096E-I Series 512K X 8 BIT LOW VOLTAGE CMOS SRAM (January, 2002, Version 2.0) 2 AMIC Technology, Inc. Features n Power supply range: 2.7V to 3.6V n Access times: 55ns / 70ns (max.) n Current: Very low power version: Operating: 30mA (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 Data retention voltage: 2V (min.) n Available in 32-pin TSOP/TSSOP 36-ball CSP package General Description The LP62S4096E-I is a low operating current 4,194,304-bit static random access memory organized as 524,288 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. n CE2 pin for CSP package only Product Family Power Dissipation Product Family Operating Temperature VCC Range Speed Data Retention (ICCDR, Typ.)
