Description
The Atmel ? AT27C040 is a low-power, high-performance, 4,194,304-bit, One-Time
Programmable, Read-Only Memory (OTP EPROM) organized as 512K by 8 bits. The
AT27C040 requires only one 5V power supply in normal Read mode operation. Any
byte can be accessed in less than 70ns, eliminating the need for speed reducing wait
states on high-performance microprocessor systems.
The Atmel scaled CMOS technology provides low active power consumption and fast
programming. Power consumption is typically 8mA in active mode and less than 10 μ A
in standby mode.
The AT27C040 is available in a choice of industry standard, JEDEC-approved, PDIP
and PLCC packages. The device features two-line control (CE, OE) to eliminate bus
contention in high-speed systems.
The AT27C040 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 100 μ s/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.
