HM62256A Series 32,768-word × 8-bit High Speed CMOS Static RAM The Hitachi HM62256A is a CMOS static RAM organized 32-kword × 8-bit. It realizes higher performance and low power consumption by employing 0.8 µm Hi-CMOS process technology. The device, packaged in a 8 × 14 mm TSOP with thickness of 1.2 mm, 450-mil SOP (foot print pitch width), 600-mil plastic DIP, or 300-mil plastic DIP, is available for high density mounting. TSOP package is suitable for cards, and reverse type TSOP is also provided. It offers low power standby power dissipation; therefore, it is suitable for battery back up system.

A write occurs during the overlap of a low CS and a low WE. A write begins at the later transition of CS going low or WE going low. A write ends at the earlier transition of CS going high or WE going high. tWP is measured from the beginning of write to the end of write. 2. tCW is measured from CS going low to the end of write. 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the earlier of WE or CS going high to the end of write cycle. 5. During this period, I/O pins are in the output state so that the input signals of the opposite phase to the outputs must not be applied. 6. If the CS low transition occurs simultaneously with the WE low transition or after the WE transition, the output remain in a high impedance state. 7. Dout is the same phase of the write data of this write cycle. 8. Dout is the read data of next address. 9. If CS is low during this period, I/O pins are in the output state. Therefore, the input signals of the opposite phase to the output must not be applied to them. 10. This parameter is sampled and not 100% tested. 11. tOHZ and tWHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage levels. 10 HM62256A Series Low VCC Data Retention Characteristics (Ta = 0 to +70°C) This characteristics is guaranteed only for L/L-SL version.
