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) HM628512 Series Ordering Information Type No.
