SRAM Async Single 5V 8M-Bit 1M x 8 55ns 44-Pin TSOP Tray

The Hitachi HM628100I Series is 8-Mbit static RAM organized 1,048,576-word × 8-bit. HM628100I Series has realized higher density, higher performance and low power consumption by employing CMOS process technology (6-transistor memory cell). It offers low power standby power dissipation; therefore, it is suitable for battery backup systems. It is packaged in standard 44-pin TSOP II for high density surface mounting.
