AT27C512R

1. Description

The AT27C512R is a low-power, high-performance 524,288-bit one-time programma-

ble read-only memory (OTP EPROM) organized 64K by 8 bits. It requires 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-performance

microprocessor systems.

Atmel’s scaled CMOS technology provides high-speed, lower active power consump-

tion, and significantly faster programming. Power consumption is typically only 8 mA

in Active Mode and less than 10 µA in Standby.

The AT27C512R is available in a choice of industry-standard JEDEC-approved one-

time programmable (OTP) plastic PDIP, PLCC, SOIC, and TSOP packages. All

devices feature two-line control (CE, OE) to give designers the flexibility to prevent

bus contention.

With 64K byte storage capability, the AT27C512R allows firmware to be stored reli-

ably and to be accessed by the system without the delays of mass storage media.

Atmel’s AT27C512R has additional features to ensure high quality and efficient pro-

duction 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 manufacturer. This feature is used by industry-standard programming

equipment to select the proper programming algorithms and voltages.
