The Hitachi HM628128B is a CMOS static RAM organized as 131,072-word by 8-bit. It offers high density, high performance, and low power consumption through its 0.8 mm Hi-CMOS shrink process technology. This RAM features fast access times of 70ns or 85ns and low standby power dissipation, making it ideal for battery backup applications.
The device operates from a single 5V supply and is completely static, requiring no clock or timing strobe. It offers equal access and cycle times with common data input and output, and a three-state output. All inputs and outputs are directly TTL compatible.
The HM628128BLP-7 is available in a 600-mil, 32-pin plastic DIP package. Other available packages include 525-mil plastic SOP and 8mm x 20mm TSOP (normal and reverse bend types). The L/L-SL versions offer capability for battery backup operation with chip selection.
Key electrical characteristics include a typical standby power of 10 mW for the L/L-SL version and a typical operating power of 50 mW/MHz. Data retention current is 50 mA for standard versions and 15 mA for SL versions.
