2 / 14 page  A62L256 Series Preliminary 32K X 8 BIT LOW VOLTAGE CMOS SRAM PRELIMINARY (November, 2001, Version 1.4) 2 AMIC Technology, Inc. Features n External Operating Voltage: 2.7V to 3.6V n Access times: 55ns (max.): for VCC = 3.0V to 3.6V 70ns (max.): for VCC = 2.7V to 3.6V n Current: Operating (ICC1): -55 series 18mA (typ.) -70 series 12mA (typ.) Standby (ISB1): 0.05 µA (typ.) n Extended operating temperature range: -40º C to +85º C for -LLU 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: 2.0V (min.) n Available in 28-pin DIP, SOP and TSOP (forward and reverse type) packages General Description The A62L256 is a low operating current 262,144-bit static random access memory organized as 32,768 words by 8 bits and operates on a low power voltage: 2.7V to 3.6V. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. Minimum standby power is drawn by this device when CE is at a high level, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 2.0V.
