Notes: 1. t HZ is 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, t HZ maximum is less than tLZ minimum both for a given device and from device to device. 3. Address must be valid prior to or simultaneously with CS1 going low or CS2 going high.

Notes: 1. A write occurs during the overlap of a low CS1, and high CS2, and a high 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. Time tWP is measured from the beginning of write to the end of write. 2. t CW is measured from the later of CS1 going low or CS2 going high to the end of write. 3. t AS is measured from the address valid to the beginning of write. 4. t WR 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 CS1 goes low simultaneously with WE going low after WE goes low, the outputs remain in high impedance state. 7. Dout is the same phase of the written data in this write cycle. 8. Dout is the read data of the next address 9. In the write cycle with OE low fixed, tWP must satisfy the following equation to avoid a problem of data bus contention t WP tWHZ max + tDW min.

Notes: 1. Reference data at Ta = 25C. 2. 10 A max at Ta = -40 to + 40C. 3. 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.
