DESCRIPTION
The Microchip Technology Inc. 24C01A/02A/04A is a
1K/2K/4K bit Electrically Erasable PROM. The device
is organized as shown, with a standard two wire serial
interface. Advanced CMOS technology allows a signif-
icant reduction in power over NMOS serial devices. A
special feature in the 24C02A and 24C04A provides
hardware write protection for the upper half of the block.
The 24C01A and 24C02A have a page write capability
of two bytes and the 24C04A has a page length of eight
bytes. Up to eight 24C01A or 24C02A devices 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 24LCXXB.
