Description
The AT27C010 is a low-power, high-performance 1,048,576-bit one-time programma-
ble 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-perfor-
mance microprocessor systems.
In read mode, the AT27C010 typically consumes only 8 mA. Standby mode supply
current is typically less than 10 µA.

0321K–EPROM–4/2004
The AT27C010 is 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.
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 27C010 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 manu-
facturer. This feature is used by industry standard programming equipment to select the
proper programming algorithms and voltages.
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 tran-
sients 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 V CC and
Ground terminals of the device, as close to the device as possible. Additionally, to stabi-
lize 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.

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.
Note: 1. X can be VIL or VIH.
2. Refer to Programming Characteristics.
3. VH = 12.0 ± 0.5V.
4. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled
low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.

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 succes-
sive 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 ver-
ifies properly, the next address is selected until all have been checked. V
PP is then
lowered to 5.0V and VCC to 5.0V. All bytes are read again and compared with the origi-
nal data to determine if the device passes or fails.
