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 significant 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. 24C01A Organization Write Protect P...
