Description
The AT27C010/L is a low-power, high performance 1,048,576 bit one-time programmable 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 performance 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 standard JEDEC-approved one-time programmable (OTP)
plastic PDIP, PLCC, and TSOP packages. All devices feature two line control (CE, OE) to give designers the flexibility to prevent bus contention.
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these
transients may exceed data sheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high frequency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should
be connected between the VCC and Ground terminals of
the device, as close to the device as possible. Additionally,
to stabilize the supply voltage level on printed circuit
boards with large EPROM arrays, a 4.7 µF bulk electrolytic
capacitor should be utilized, again connected between the
VCC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power
supply is connected to the array.
With 128K byte storage capability, the AT27C010/L allows
firmware to be stored reliably and to be accessed by the
system without the delays of mass storage media.
Atmel’s 27C010/L have additional features to ensure high
quality and efficient production use. The Rapid Programming Algorithm reduces the time required to program the
part and guarantees reliable programming. Programming
time is typically only 100 µs/byte. The Integrated Product
Identification Code electronically identifies the device and
manufacturer. This feature is used by industry standard
programming equipment to select the proper programming algorithms and voltages.

*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
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 output pin voltage is VCC + 0.75V dc which may overshoot to +7.0V for pulses of less than 20 ns.

Notes: 1. Timing measurement reference level is 1.5V for -45
and -55 devices. Input AC drive levels are VIL =
0.0V and VIH = 3.0V. Timing measurement reference levels for all other speed grades are VOL =
0.8V and VOH = 2.0V. Input AC drive levels are VIL
= 0.45V and VIH = 2.4V.
2. OE may be delayed up to tCE - tOE after the falling
edge of CE without impact on tCE.
3. OE may be delayed up to tACC - tOE after the address is valid
without impact on tACC.
4. This parameter is only sampled and is not 100% tested.
5. Output float is defined as the point when data is no longer
driven.

2. tOE and tDFP are characteristics of the device but
must be accommodated by the programmer.

AC Programming Characteristics
Rapid Programming Algorithm
TA = 25 ± 5°C, VCC = 6.5 ± 0.25 V, VPP = 13.0 ± 0.25V
A 100 µs PGM pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and
VPP is raised to 13.0V. Each address is first programmed
with one 100 µs PGM pulse without verification. Then a
verification / reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to
10 successive 100 µs pulses are applied with a verification 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 selected until all have been checked. VPP is then lowered to
5.0V and VCC to 5.0V. All bytes are read again and compared with the original data to determine if the device
passes or fails.
