GENERAL DESCRIPTION  
PACKAGE PINOUT  
The 32K x 8 High Temperature Static RAM is a high  
performance 32,768 word x 8-bit static random access  
memory with industry-standard functionality. It is fabri-  
cated with Honeywell’s HTMOS™ technology, and is  
designed for use in systems operating in severe high  
temperature environments.

The RAM requires only a single 5 V ± 10% power supply  
and has CMOS compatible I/O. Power consumption is  
typically less than 30 mW/MHz in operation, and less than  
10 mW when de-selected. The RAM read operation is fully  
asynchronous, with an associated typical access time of  
50 ns at 5 V.

The RAM provides guaranteed performance over the full  
-55 to +225°C temperature range. Typically, parts will  
operate up to +300°C for a year, with derated perfor-  
mance. All parts are burned in at 250°C to eliminate infant  
mortality.
