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.
