Notes (1) CS2 controls address buffer, WE buffer, CS1 buffer and OE buffer. If CS2 controls data retention mode,
Vin levels (WE,OE,CS1,I/O) can be in the high impedance state. If CS1 controls Data Retention mode,
CS2 must be ≥ VCC - 0.2V or 0V ≤ CS2 ≤ 0.2V. The other input levels (address, WE,OE,I/O) can be in the
high impedance state.

Notes:
(1) WE is High for Read Cycle.
(2) Address valid prior to or coincident with CS1 transition low or CS2 high.
(3) tCHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not
referenced to output voltage levels. At any given temperature and voltage condition, tCHZ max is less than
tCLZ min both for a given device and from device to device. This parameter is sampled and not 100% tested.

AC Characteristics 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) tWR is measured from the earlier of CS1 or WE going high or CS2 going high to the end of write cycle.
(3) During this period, I/O pins are in the output state. Input signals out of phase must not be applied.
(4) If CS1 goes low simultaneously with WE going low or after WE going low, outputs remain in high impedance state.
(5) OE is continuously low. (OE=VIL)
(6) Dout is in the same phase as written data of this write cycle.
(7) Dout is the read data of next address.
(8) If CS1 is low and CS2 is high during this period, I/O pins are in the output state. Input signals out of phase must not be
applied to I/O pins.
(9) tWHZ is defined as the time at which the outputs achieve the open circuit conditions and is not referenced to output voltage
levels. These parameters are sampled and not 100% tested.
