The pinout is the JEDEC 28 pin, 8-bit wide standard, which allows easy memory board layouts which accommodate a variety of industry standard ROM, PROM, EPROM, EEPROM and RMs. The is ideally suited for use in microprocessor based systems. In particular, interfacing with the Intersil 80C86 and 80C88 microprocessors is simplified by the convenient output enable (G) input. The is a full CMOS RM which utilizes an array of six transistor (6T) memory cells for the most stable and lowest possible standby supply current over the full military temperature range.

5 Low Voltage Data Retention Intersil CMOS RMs are designed with battery backup in mind. Data Retention voltage and supply current are guaranteed over the operating temperature range. The following rules ensure data retention: 1. The RM must be kept disabled during data retention. This is accomplished by holding the pin between -0.3V and GND. 2. During power-up and power-down transitions, must be held between -0.3V and 10% of V CC. 3. The RM can begin operating one TVX after V CC reaches the minimum operating voltage of 4.5V.
