General Description
The ACT–E128K32 is a high speed, 4 megabit, CMOS EEPROM multichip module (MCM) designed for full temperature range military, space, or high reliability applications. The MCM can be organized as a 256K x 16 bits or 512K x 8 bits device and is input and output CMOS and TTL compatible. Writing is executed when the write enable (WE) and chip enable (CE) inputs are low and output enable (OE) is high. Reading is accomplished when WE is high and CE and OE are both low. Access times grades of 120, 140, 150, 200, 250 & 300ns are standard.
