HM628128A Series
131,072-word × 8-bit High Speed CMOS Static RAM
Rev. X
January 1995
The Hitachi HM628128A is a CMOS static RAM
organized 128 kword × 8 bit. It realizes higher
density, higher performance and low power
consumption by employing 0.8 µm Hi-CMOS
process technology.
Features
• High speed
— Fast access time: 55/70/85/100 ns (max)
• Low power
— Active: 75 mW (typ)
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 × 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.
— Standby: 10 µW (typ)
• Single 5 V supply
• Completely static memory
No clock or timing strobe required
• Equal access and cycle times
• Common data input and output
Three state output
• Directly TTL compatible
All inputs and outputs
• Capability of battery back up operation

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

2. 6 µA max at Ta = 0 to 40˚C (L-L-version).
3. 3 µA max at Ta = 0 to 40˚C (L-SL-version).
4. 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.
