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 rapid programming 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.
