AT27C1024

1. 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 orga-

nization make this part ideal for high-performance 16- and 32-bit microprocessor

systems.

In read mode, the AT27C1024 typically consumes 15 mA. Standby mode supply cur-

rent is typically less than 10 µA.

The AT27C1024 is available in industry-standard JEDEC-approved one-time pro-

grammable (OTP) plastic PDIP, PLCC, and VSOP 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 AT27C1024 have additional features to ensure high quality and efficient pro-

duction use. The RapidProgramming 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.
