GENERAL DESCRIPTION The 32K x 8 Radiation Hardened ROM is a high performance 32,768 word x 8-bit read only memory with industrystandard functionality. It is fabricated with Honeywell’s radiation hardened technology, and is designed for use in systems operating in radiation environments. The ROM operates over the full military temperature range and requires only a single 5 V ± 10% power supply. The ROM is available with either TTL or CMOS compatible I/O. Power consumption is typically less than 15 mW/MHz in operation, and less than 5 mW when de-selected. The ROM operation is fully asynchronous, with an associated typical access time of 14 ns. Honeywell’s enhanced SOI RICMOS™ IV (Radiation Insensitive CMOS) technology is radiation hardened th...
