Full static operation, no clock or refreshing required All inputs and outputs are directly TTL-compatible Common I/O using three-state output Data retention voltage: 2.0V (min.) Available in 28-pin, DIP/SOP and TSOP Pb-Free package only All Pb-free (Lead-free) products are RoHS compliant 35mA (max.) 10A (max.) 35mA (max.) 15A (max.) 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 A623308A is a low operating current 65,536-bit static random access memory organized as 8,192 words by 8 bits and operates on a voltage from 4.5V to 5.5V. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures.
