Notes: 1. t CHZ, tOHZ and t WHZ are defined as the time at which the outputs achieve the open circuit conditions
and are not referred to output voltage levels.
2. This parameter is sampled and not 100% tested.
3. At any given temperature and voltage condition, t HZ max is less than tLZ min both for a given device
and from device to device.
4. A write occurs during the overlap (tWP) 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.
5. t CW is measured from CS1 going low or CS2 going high to the end of write.
6. t AS is measured from the address valid to the beginning of write.
7. t WR is measured from the earlier of WE or CS1 going high or CS2 going low to the end of write
cycle.
8. 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.
9. If the CS1 goes low or CS2 going high simultaneously with WE going low or after WE going low,
the output remain in a high impedance state.
10. Dout is the same phase of the write data of this write cycle.
11. Dout is the read data of next address.
12. If CS1 is low and CS2 high 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 to them.
13. In the write cycle with OE low fixed, tWP must satisfy the following equation to avoid a problem of
data bus contention. t WP ≥ tDW min + tWHZ max

Notes: 1. This characteristic is guaranteed only for L-version, 30 µA max. at Ta = –40 to +40°C.
2. 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.
3. Typical values are at VCC = 3.0 V, Ta = +25°C and specified loading, and not guaranteed.
