General Description

Block Diagram – PGA Type Package (P3,P7) & CQFP (F2)

The ACT–E128K32 is a highspeed, 4 megabit, CMOSEEPROM multichip module(MCM) designed for fulltemperature range military,space, or high reliabilityapplications. The MCM can beorganized as a 256K x 16 bitsor 512K x 8 bits device and isinput and output CMOS andTTL compatible. Writing isAccess times grades of120,140,150,200,250&300ns

are standard.

The ACT–E128K32 ispackaged in a choice ofhermetically sealed co-firedceramic packages, a 66 pin,1.08"sq PGA or a 68 lead, .88"sq gullwing CQFP. The deviceoperates over the temperaturerange of -55°C to +125°C andmilitary environment.
