Special Order  
Full Military (-55°C to +125°C) Temperature Range  
+3.3V Power Supply  
Choice of Surface Mount or PGA Type Co-fired Packages:  
68–Lead, Dual-Cavity CQFP (F2), .88"SQ x .20"max (.18"max thickness  
available, contact factory for details) (Drops into the 68 Lead JEDEC .99"SQ  
CQFJ footprint)  
General Description  
The ACT–S128K32V is a High  
Speed 4 megabit CMOS SRAM  
66–Lead, PGA-Type (P7), 1.08"SQ x .160"max  
Multichip  
Module  
(MCM)  
Internal Decoupling Capacitors  
DESC SMD# Pending  
designed for full temperature  
range, 3.3V Power Supply,  
military, space, or high reliability  
mass memory and fast cache  
applications.  
Block Diagram – PGA Type Package(P7) & CQFP(F2)  
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.
