Description
The Atmel AT27C1024 is a low-power, high-performance 1,048,576-bit, one-time pro-
grammable, read-only memory (OTP EPROM) organized as 64K by 16 bits. It requires only
one 5V power supply in normal read mode operation. Any word can be accessed in less
than 45ns, eliminating the need for speed reducing WAIT states. The x16 organization
makes this part ideal for high-performance, 16- and 32-bit microprocessor systems.
In read mode, the AT27C1024 typically consumes 15mA. Standby mode supply current is
typically less than 10µA.
The AT27C1024 is available in industry-standard, JEDEC-approved, one-time programma-
ble (OTP) PDIP and PLCC 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.
The AT27C1024 has additional features to ensure high quality and efficient production use.
The rapidprogramming algorithm reduces the time required to program the part and guar-
antees reliable programming. Programming time is typically only 100µs/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 pro-
gramming 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 transients may exceed datasheet limits, resulting in device nonconformance.
At a minimum, a 0.1µF, 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 4.7µF 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.

Rapid programming algorithm
A 100µs 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 100µs PGM pulse without verification. Then a
verification/reprogramming loop is executed for each address. In the event a word fails to pass verification, up to 10
successive 100µs 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.
