Description
The Atmel® AT27C512R is a low-power, high-performance, 524,288-bit,
one-time programmable, read-only memory (OTP EPROM) organized as
64K by 8 bits. It requires only one 5V power supply in normal read
mode operation. Any byte can be accessed in less than 45ns,
eliminating the need for speed reducing WAIT states on
high-performance microprocessor systems.
The Atmel scaled CMOS technology provides high speed, lower active
power consumption, and significantly faster programming. Power
consumption is typically only 8mA in active mode and less than 10µA
in standby mode.
The AT27C512R is available in a choice of industry-standard,
JEDEC-approved, one-time programmable (OTP) PDIP and PLCC packages.
All devices feature two-line control (CE, OE) to give designers the
flexibility to prevent bus contention

The AT27C512R has additional features to ensure high quality and
efficient production use. The rapid programming algorithm reduces
the time required to program the part and guarantees reliable
programming. Programming time is typically only 100µs/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.
