The Intersil Satellite Applications Flow™ (SAF) devices are fully tested and guaranteed to 100kRAD total dose. These QML Class T devices are processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers while maintaining a high level of reliability. The Intersil HS-6664RH-T is a radiation hardened 64K CMOS PROM, organized in an 8K word by 8-bit format. The chip is manufactured using a radiation hardened CMOS process and utilizes synchronous circuit design techniques to achieve high-speed performance with very low power dissipation. On-chip address latches are provided, allowing easy interfacing with microprocessors that use a multiplexed address/data bus structure. The output enable control simplifies system interfacing by allowing output data bus control in addition to the chip enable control. All bits are manufactured storing a logical 0 and can be selectively programmed for a logical 1 at any bit location.
