CIRCUIT TECHNOLOGY
General Description
The ACT–S128K32V is a High Speed 4 megabit CMOS SRAM Multichip Module (MCM) designed for full temperature range, 3.3V Power Supply, military, space, or high reliability mass memory and fast cache applications. The MCM can be organized as a 128K x 32 bits, 256K x 16 bits or 512k x 8 bits device and is input and output TTL compatible. Writing is executed when the write enable (WE) and chip enable (CE) inputs are low. Reading is accomplished when WE is high and CE and output enable (OE) are both low. Access time grades of 17ns, 20ns, 25ns, 35ns, 45ns and 55ns maximum are standard. The products are designed for operation over the temperature range of -55°C to +125°C and screened under the full military environment. DESC Standard Military Drawing (SMD) part numbers are pending. The ACT-S128K32V is manufactured in Aeroflex’s ……
