ADE-203-236F (Z)
Rev. 6.0
Jun. 9, 1995
Description
The Hitachi HM628512 is a 4-Mbit static RAM organized 512-kword × 8-bit. It realizes igher density, higher
performance and low power consumption by employing 0.5 µm 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. LP-version is suitable for battery backup system.
Features
• High speed: Fast access time:
55/65/70 ns (max)
• Low power
Standby: 10 µW (typ) (L/L-SL version)
Operation: 75 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
• Capability of battery backup operation (L/L-SL version)
