Description
The AT27C1024 is a low-power, high-performance 1,048,576 bit one-time program-
mable read only memory (OTP EPROM) organized 64K by 16 bits. It requires only
one 5V power supply in normal read mode operation. Any word can be accessed in
less than 45 ns, eliminating the need for speed reducing WAIT states. The by-16
organization make this part ideal for high-performance 16- and 32-bit microprocessor
systems.

AT27C1024
In read mode, the AT27C1024 typically consumes 15 mA.
Standby mode supply current is typically less than 10 µA.
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 uti-
lized 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.
The AT27C1024 is available in industry standard JEDEC-
approved one-time programmable (OTP) plastic PDIP,
PLCC, and TSOP packages. The device features two-line
control (CE, OE) to eliminate bus contention in high-speed
systems.
With high density 64K word storage capability, the
AT27C1024 allows firmware to be stored reliably and to be
accessed by the system without the delays of mass storage
media.
Atmel’s 27C1024 have additional features to ensure high
quality and efficient production use. The Rapid™ Program-
ming Algorithm reduces the time required to program the
part and guarantees reliable programming. Programming
time is typically only 100 µs/word. 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.

AC Waveforms for Read Operation
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.

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 ver-
ification / reprogramming loop is executed for each
address. In the event a word fails to pass verification, up to
10 successive 100 µs pulses are applied with a verification
after each pulse. If the word fails to verify after 10 pulses
have been applied, the part is considered failed. After the
word 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 words are read again and compared with the
original data to determine if the device passes or fails.
