HM628512C Series
4 M SRAM (512-kword × 8-bit)
ADE-203-1212 (Z)
Preliminary
Rev. 0.0
Sep. 12, 2000
Description
The Hitachi HM628512C is a 4-Mbit static RAM organized 512-kword × 8-bit. It realizes higher density,
higher performance and low power consumption by employing Hi-CMOS process technology. The device,
packaged in a 525-mil SOP (foot print pitch width) or 400-mil TSOP TYPE II or 600-mil plastic DIP, is
available for high density mounting. The HM628512C is suitable for battery backup system.
Features
• Single 5 V supply
• Access time: 55/70 ns (max)
• Power dissipation
Active: 50 mW/MHz (typ)
Standby: 10 µW (typ)
• 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
Preliminary: The specification of this device are subject to change without notice. Please contact your
nearest Hitachi’s Sales Dept. regarding specification.
