AT27C010
1. Description
The AT27C010 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.
In read mode, the AT27C010 typically consumes only 8 mA. Standby mode supply
current is typically less than 10 µA.
The AT27C010 is available in a choice of industry-standard JEDEC-approved onetime 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.
With 128K byte storage capability, the AT27C010 allows firmware to be stored reliably
and to be accessed by the system without the delays of mass storage media.
Atmel’s AT27C010 has 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.

3. System Considerations
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 datasheet 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.

*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 +7.0 volts for pulses of less than 20 ns.

18. Rapid Programming Algorithm
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.
