Description
The AT27C010/L is a low-power, high performance 1,048,576 bit one-time program-
mable read only memory (OTP EPROM) organized as 128K by 8 bits. They require
only one 5V power supply in normal read mode operation. Any byte can be accessed
in less than 45 ns, eliminating the need for speed reducing WAIT states on high per-
formance microprocessor systems.
Two power versions are offered. In read mode, the AT27C010 typically consumes 25
mA while the AT27C010L requires only 8 mA. Standby mode supply current for both
parts is typically less than 10 µA.

System Considerations
The AT27C010/L in available in a choice of industry stand-

ture two line control (CE, OE) to give designers the flexibil-
ity to prevent bus contention.
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excur-
sions. Unless accommodated by the system design, these
transients may exceed data sheet limits, resulting in de-
vice non-conformance. At a minimum, a 0.1 µF high fre-
quency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should

*NOTICE: Stresses beyond those listed under “Absolute Maxi-

for extended periods may affect device reliability.
Note: 1. Minimum voltage is -0.6V dc which may undershoot
to -2.0V for pulses of less than 20 ns. Maximum out-

Notes: 1. The Input Timing Reference is 0.8V for VIL and
2.0V for VIH.
3. When programming the AT27C010/L, a 0.1 µF capacitor is
required across VPP and ground to suppress spurious volt-
age transients.
2. tOE and tDFP are characteristics of the device but
must be accommodated by the programmer.

with one 100 µs PGM pulse without verification. Then a
verification / reprogramming loop is executed for each ad-
dress. In the event a byte fails to pass verification, up to
10 successive 100 µs pulses are applied with a verifica-
tion after each pulse. If the byte fails to verify after 10
pulses have been applied, the part is considered failed.
After the byte verifies properly, the next address is se-
lected until all have been checked. V is then lowered to
5.0V and V to 5.0V. All bytes are read again and com-
pared with the original data to determine if the device
passes or fails.
