DESCRIPTION
The Microchip Technology Inc. 24C04A is a 4K bit Elec-
trically Erasable PROM. The device is organized as
with a standard two wire serial interface. Advanced
CMOS technology allows a significant reduction in
power over NMOS serial devices. A special feature
provides hardware write protection for the upper half of
the block. The 24C04A has a page write capability of
up to eight bytes, and up to four 24C04A devices may
be connected to the same two wire bus.
This device offers fast (1ms) byte write and
extended (-40°C to 125°C) temperature operation.
It is recommended that all other applications use
Microchip’s 24LC04B.
