and the outputs are placed in the high impedance state, independent of the OE#

input.

The device enters the CMOS standby mode when the CE# and RESET# inputs are

both held at Vcc ± 0.2 V. The device requires standard access time (tCE) for read

access, before it is ready to read data.

If the device is deselected during erasure or programming, the device draws ac-

tive current until the operation is completed.

ICC5 in the “DC Characteristics” section represents the standby current

specification.

Caution: entering the standby mode via the RESET# pin also resets the device

to the read mode and floats the data I/O pins. Furthermore, entering ICC7 during

a program or erase operation will leave erroneous data in the address locations

being operated on at the time of the RESET# pulse. These locations require up-

dating after the device resumes standard operations. Refer to the “RESET#:

Hardware Reset Pin” section for further discussion of the RESET# pin and its

functions.

RESET#: Hardware Reset Pin

The RESET# pin is an active low signal that is used to reset the device under any

circumstances. A logic “0” on this pin forces the device out of any mode that is

currently executing back to the reset state. The RESET# pin may be tied to the

system reset circuitry. A system reset would thus also reset the device. To avoid

a potential bus contention during a system reset, the device is isolated from the

DQ data bus by tristating the data output pins for the duration of the RESET

pulse. All pins are “don’t care” during the reset operation.

If RESET# is asserted during a program or erase operation, the RY/BY# pin re-

mains low until the reset operation is internally complete. This action requires

between 1 µs and 7µs for either Chip Erase or Sector Erase. The RY/BY# pin can

be used to determine when the reset operation is complete. Otherwise, allow for

the maximum reset time of 11 µs. If RESET# is asserted when a program or erase

operation is not executing (RY/BY# = “1”), the reset operation will complete

within 500 ns. The Simultaneous Read/Write feature of this device allows the user

to read a bank after 500 ns if the bank was in the read/reset mode at the time

RESET# was asserted. If one of the banks was in the middle of either a program

or erase operation when RESET# was asserted, the user must wait 11 µs before

accessing that bank.

Asserting RESET# during a program or erase operation leaves erroneous data

stored in the address locations being operated on at the time of device reset.

These locations need updating after the reset operation is complete. See Figure

19 for timing specifications.

Asserting RESET# active during VCC and VIO power-up is required to guarantee

proper device initialization until VCC and VIO have reached their steady state

voltages.

Output Disable Mode

See Table 1 Device Bus Operation for OE# Operation in Output Disable Mode.

Autoselect Mode

The autoselect mode provides manufacturer and device identification, and sector

protection verification, through identifier codes output on DQ7–DQ0. This mode
