GENERAL DESCRIPTION
The 32K x 8 Radiation Hardened ROM is a high perform ance 32,768 word x 8-bit read only memory with industry standard 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.

ROHM was established in Kyoto, Japan, in 1958. ROHM designs and manufactures semiconductors, integrated circuits and other electronic components. These components find a home in the dynamic and ever-growing wireless, computer, automotive and consumer electronics markets. Some of the most innovative equipment and devices use ROHM products.
ROHM's presence in the North American market continues to expand with a logistic headquarters in San Diego, California, a design center in San Jose, California, a QA Center in Novi, Michigan, a sales office in Guadalajara, Mexico and a sales network that covers marketing, sales, and engineering support for the North and South American clients from Canada to Brazil. In addition to a direct sales force, ROHM enjoys the collaboration of several sales-representative organizations and industry leading electronics distributors.
For more than forty years, ROHM has stayed focused on the fundamental philosophy of customization. The company has worked closely with equipment manufacturers to develop next generation equipment and use the technology acquired through these efforts to propose system solutions to its customers and continually provide them with high added values.
The majority of ROHM's manufacturing equipment has been developed in-house. This has given ROHM the ability to respond immediately to changing market needs. The extent of ROHM products is a result of innovations and the capability to adjust to market demands. Automotive, telecommunication, computer, and consumer OEMs are among the leading end users of ROHM products.
