Description
The Hitachi HM628512CI is a 4-Mbit static RAM organized 512-kword × 8-bit. HM628512CI Series has
realized higher density, higher performance and low power consumption by employing Hi-CMOS process
technology. The HM628512CI 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.
