PRODUCT DESCRIPTION

The UT28F64 amorphous silicon anti-fuse PROM is a high

performance, asynchronous, radiation-hardened,

8K x 8 programmable memory device. The UT28F64 PROM

features fully asychronous operation requiring no external clocks

or timing strobes. An advanced radiation-hardened twin-well

CMOS process technology is used to implement the UT28F64.

The combination of radiation- hardness, fast access time, and low

power consumption make the UT28F64 ideal for high speed

systems designed for operation in radiation environments.
