Functional Description
Read Mode
Auto Identify Mode
The A276308 has two control functions, both of which
must be logically active in order to obtain data at the
outputs. CE is the power control and should be used for
device selection. OE is the output control and should be
used to data to the output pins, which is independent of
device selection. Assuming that addresses are stable,
address access time (tAA) is equal to the delay from CE
to output (tCE). Data is available at the output after a
delay (tOE) from the falling edge of OE , as long as CE
has been low and the addresses have been stable for at
least tAA - tOE.
The auto identify mode allows the reading out of a binary
code from a EPROM that will identify its manufacturer
and type. This mode is intended for use by programming
equipment for the purpose of automatically matching the
device to be programmed with its corresponding
programming algorithm.
To activate the mode, the programming equipment must
apply 12.0V ± 0.5V on address line A9 of the A276308.
Three identification code can be read from data output pin
by toggling A0 and A1. The other addresses must be held
at VIL during this mode. Byte 0 (with A0 at VIL, A1 at VIL)
represents the manufacturer code which is 37H. Byte 1
and Byte 2 represent the device code and continuation
code, which is 3DH and 7FH respectively. All identifiers
for these codes will possess odd parity, with MSB (IO7)
defined the parity bit.
Standby Mode
The A276308 has a standby mode which reduces the
active current from 30mA to 100µA. The A276308 is
placed in the standby mode by applying a CMOS high
signal to CE . When in the standby mode, the output are
in a high impedance state, independent of the OE .

These are stress ratings only. Functional operation of
this device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied or intended. Exposure to the absolute
maximum rating conditions for extended periods may
affect device reliability.
Notes:
1. During voltage transitions, the input may undershoot GND to -2.0V for periods less than 20 ns. Maximum DC voltage on
input and I/O may overshoot to VCC + 2.0V for periods less than 20 ns.
2. When transitions, A9 and VPP may undershoot GND to -2.0V for periods less than 20 ns. Maximum DC input voltage
on A9 and VPP is +13.5V which may overshoot to 14.0V for period less than 20 ns.

an additional pulse programming is applied for a
maximum of 25 pulses. On completion of 1 byte
programming and, The verified address is incremented.
After the final address is completed, all bytes are verified
again with VCC = 5.0 Volt.
Programming and Program Verify
The programming flowchart is shown in Page 10.
The A276308 is shipped with all bits being set to "1".
Programming causes relevant bits to be changed to "0".
The programming mode is started by setting VCC to
6.25V, OE /VPP to +12.75V and CE is at VIL. Data to
be programmed can be directly input in the 8 bit format
through the data bus.
Program Inhibit
This mode is used to program one of multiple A276308
whose VCC, address bus and data bus are connected in
parallel. When programming is performed, other
A276308 can be inhibited from being programmed by
setting their CE pins to VIH and OE /VPP pins to
+12.75V.
The write programming algorithm reduces programming
time by using 100µs pulse followed by a byte verification
to determine whether the byte has been successfully
programmed. If the data does not pass the verification,
