READ ONLY MODE
When V
is inactive. The device can either read array or autose-
lect data, or be standby mode.
Read
The device functions as a read only memory when V
< V
must be satisfied in order to output data. CE# controls
power to the device. This pin should be used for spe-
cific device selection. OE# controls the device outputs
and should be used to gate data to the output pins if a
device is selected.
Address access time t
stable addresses to valid output data. The chip enable
access time t
stable CE# to valid data at the output pins. The output
enable access time is the delay from the falling edge of
OE# to valid data at the output pins (assuming the ad-
dresses have been stable at least t
Standby Mode
The device has two standby modes. The CMOS
standby mode (CE# input held at V
sumes less than 100 µA of current. TTL standby mode
(CE# is held at V
to less than 1mA. When in the standby mode the out-
puts are in a high impedance state, independent of the
OE# input.
If the device is deselected during erasure, program-
ming, or program/erase verification, the device will
draw active current until the operation is terminated.

Output Disable
Output from the device is disabled when OE# is at a
logic high level. When disabled, output pins are in a
high impedance state.
Auto Select
Flash memories can be programmed in-system or in a
standard PROM programmer. The device may be sol-
dered to the circuit board upon receipt of shipment and
programmed in-system. Alternatively, the device may
initially be programmed in a PROM programmer prior
to soldering the device to the board.
The Auto select mode allows the reading out of a binary
code from the device that will identify its manufacturer
and type. This mode is intended for the purpose
of automatically matching the device to be pro-
grammed with its corresponding programming algo-
r ithm. Thi s mode is functional over the enti re
temperature range of the device.
Programming In A PROM Programmer
To activate this mode, the programming equipment
must force V

codes will exhibit odd parity with the MSB (DQ7) de-
fined as the parity bit.
