HM9264B Series
64 k SRAM (8-kword × 8-bit)
ADE-203-618C (Z)
Rev. 3.0
Nov. 1997
Description
The Hitachi HM9264B is 64k-bit static RAM organized 8-kword × 8-bit. It realizes higher performance
and low power consumption by 1.5 µm CMOS process technology. The device, packaged in 450 mil
SOP (foot print pitch width), 600 mil plastic DIP, is available for high density mounting.
Features
• High speed
Fast access time: 85/100 ns (max)
• Low power
Standby: 10 µW (typ)
Operation: 15 mW (typ) (f = 1 MHz)
• Single 5 V supply
• Completely static memory
No clock or timing strobe required
• Equal access and cycle times
• Common data input and output
Three state output
• Directly TTL compatible
All inputs and outputs
• Battery backup operation capability
Note: HM9264B series can't be applied for Aerospace, Aircraft, Nucleus Plants, Main Flame
Computers, Medical Life-support System, and Automobile Engine Control and Industrial
machines. (e.g. Communication Hubs, NC, and others.)
