Description

The Hitachi HM628512BI is a 4-Mbit static RAM organized 512-kword × 8-bit. HM628512BI Series has

realized higher density, higher performance and low power consumption by employing Hi-CMOS process

technology. The HM628512BI Series offers low power standby power dissipation; therefore, it is suitable for

battery backup systems. It has packaged in 32-pin SOP, 32-pin TSOP II and 32-pin DIP.

• Access time: 70/85 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

• Operating temperature: –40 to +85˚C
