ACT-S128K32 High Speed  
4 Megabit SRAM Multichip Module  
Features  
4 Low Power CMOS 128K x 8 SRAMs in one MCM  
Overall configuration as 128K x 32  
CIRCUIT TECHNOLOGY  
www.aeroflex.com  
Input and Output TTL Compatible  
17, 20, 25, 35, 45 & 55ns Access Times, 15ns Available by Special Order  
Full Military (-55°C to +125°C) Temperature Range  
+5V Power Supply  
General Description  
Choice of 7 Hermetically sealed Co-fired Packages:  
68–Lead, Low Profile CQFP (F1), 1.56"SQ x .140"max  
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)  
The ACT–S128K32 is a High  
Speed 4 megabit CMOS SRAM  
Multichip  
Module  
(MCM)  
designed for full temperature  
range, military, space, or high  
reliability mass memory and  
fast cache applications.  
68–Lead, Single-Cavity CQFP (F18), .94"SQ x .140"max (Drops into the 68  
Lead JEDEC .99"SQ CQFJ footprint)  
66–Lead, PGA-Type (P2,P6 with/without shoulders), 1.185"SQ x .245"max  
66–Lead, PGA-Type (P7,P3 with/without shoulders), 1.08"SQ x .160"max  
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.
