HM628512B - 4 M SRAM (512-kword x 8-bit)

General Description

The Hitachi HM628512B is a 4-Mbit static RAM organized 512-kword × 8-bit.

It realizes higher density, higher performance and low power consumption by employing 0.35 µm Hi-CMOS process technology.

Key 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 HM628512B Series Ordering Information Type No. HM628512BLP-5 HM628512BLP-7 HM628512BLP-5SL HM6.
