A623308 Series Preliminary 8K X 8 BIT CMOS SRAM 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: 10µA (max.) A623308-SI/SU series: Operating: 35mA (max.) Standby: 15µA (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 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. 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.

A Write occurs during the overlap (tWP) of a low CE and a low WE . tWR is measured from the earliest of CE or WE going high to the end of the Write cycle. If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs remain in a high impedance state. 5. tCW is measured from the later of CE going low to the end of Write. 6. OE level is high or low. 7. Transition is measured ±500mV from steady. This parameter is sampled and not 100% tested. PRELIMINARY (December, 2002, Version 0.3) 8 AMIC Technology, Corp.
