HM628128A Series
131,072-word x 8-bit High Speed CMOS Static RAM
Rev. X January 1995
The Hitachi HM628128A is a CMOS static RAM organized 128 kword x 8 bit. It realizes higher density, higher performance and low power consumption by employing 0.8 m Hi-CMOS process technology. It offers low power standby power dissipation; therefore, it is suitable for battery back-up systems. The device, packaged in a 525-mil SOP (460-mil body SOP) or a 600-mil plastic DIP, or a 8 x 20 mm TSOP with thickness of 1.2 mm, is available for high density mounting. TSOP package is suitable for cards, and reverse type TSOP is also provided.

Notes: 1. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referred to output voltage levels. 2. At any given temperature and voltage condition, tHZ max is less than tLZ min both for a given device and from device to device. 3. This parameter is sampled and not 100% tested. 4. WE is high for read cycle.

Notes: 1. A write occurs during the overlap of a low CS1, a high CS2, and a low WE. A write begins at the latest transition among CS1 going low, CS2 going high, and WE going low. A write ends at the earliest transition among CS1 going high, CS2 going low, and WE going high. tWP is measured from the beginning of write to the end of write. 2. tCW is measured from the later of CS1 going low or CS2 going high to the end of write. 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the earliest of CS1 or WE going high or CS2 going low to the end of write cycle. 5. During this period, I/O pins are in the output state; therefore, the input signals of the opposite phase to the outputs must not be applied. 6. If the CS1 goes low simultaneously with WE going low or after the WE going low, the outputs remain in a high impedance state. 7. Dout is the same phase of the latest written data in this write cycle. 8. Dout is the read data of next address. 9. If CS1 is low and CS2 high during this period, I/O pins are in the output state. Therefore, the input signals of opposite phase to the outputs must not be applied to them. 10. This parameter is sampled and not 100% tested. 11. In the write cycle with OE low fixed, tWP must satisfy the following equation to avoid a problem of 11

CS2 controls address buffer, WE buffer, CS1 buffer, OE buffer, and Din buffer. If CS2 controls data retention mode, Vin levels (address, WE, OE, CS1, I/O) can be in the high impedance state. If CS1 controls data retention mode, CS2 must be CS2 VCC - 0.2 V or 0 V CS2 0.2 V. The other input levels (address, WE, OE, I/O) can be in the high impedance state.
