1 HM May 2002 K x synchronous CMOS Static RM Features Full CMOS Design Six Transistor Memory Cell Low Standby Supply Current µ Low Operating Supply Current m Fast ddress ccess Time ns Low Data Retention Supply Voltage V CMOS/TTL Compatible Inputs/Outputs JEDEC pproved Pinout Equal Cycle and ccess Times No Clocks or Strobes Required Gated Inputs No Pull-Up or Pull-Down Resistors Required Easy Microprocessor Interfacing Dual Chip Enable Control Ordering Information Description The HM is a CMOS 192 x -bit Static Random ccess Memory. The pinout is the JEDEC 2 pin, -bit wide standard, which allows easy memory board layouts which accommodate a variety of industry standard ROM, PROM, EPROM, EEPROM and RMs. The HM is ideally suited for use in microprocessor based systems. In particular, interfacing with the Intersil 0C6 and 0C microprocessors is simplified by the convenient output enable (G) input. The HM 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.
