PRODUCT DESCRIPTION
The UT28F256 amorphous silicon anti-fuse PROM is a high
performance, asynchronous, radiation-hardened,
32K x 8 programmable memory device. The UT28F256 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 UT28F256.
The combination of radiation-hardness, fast access time, and low
power consumption make the UT28F256 ideal for high speed
systems designed for operation in radiation environments.
