Description
The Hitachi HM628512BI is a 4-Mbit static RAM organized 512-kword à 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.

⢠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: â40 to +85ËC
