RAD Tolerant  
ACT–RS128K32 High Speed  
4 Megabit SRAM Multichip Module  
Preliminary  
Features  
4 Low Power CMOS 128K x 8 SRAMs in one MCM  
Overall configuration as 128K x 32  
Tolerant to 30KRad (Si)  
CIRCUIT TECHNOLOGY  
2
www.aeroflex.com/act1.htm  
Latch-up Immunity to 112MeV/(mg/cm )  
Input and Output TTL Compatible  
35 & 45ns Access Times  
Full Military (-55°C to +125°C) Temperature Range  
For Class K devices per MIL-PRF-38534 - Consult Factory  
+5V Power Supply  
General Description  
Choice of 4 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–RS128K32 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.  
66–Lead, PGA-Type (P1), 1.385"SQ x .245"max  
Internal Decoupling Capacitors  
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  
35ns and 45ns maximum are  
standard.
