2 / 13 page A623308 Series Preliminary 8K X 8 BIT CMOS SRAM PRELIMINARY (December, 2002, Version 0.3) 1 AMIC Technology, Corp. Features n External Operating Voltage: 4.5V to 5.5V n Access times: 70 ns (max.) n Current: A623308-S series: Operating: 35mA (max.) Standby: 10 µA (max.) A623308-SI/SU series: Operating: 35mA (max.) Standby: 15 µA (max.) n Extended operating temperature range: 0 °C to 70°C for -S series, -25 °C to 85°C for -SI series, -40°C to 85 °C for -SU 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 SOP and TSOP (forward type) packages General Description The A623308 is a low operating current 65,536-bit static random access memory organized as 8,192 words by 8 bits and operates on a single 5V power supply. 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.
