The Microchip Technology Inc. 24C02C is a 2K bit R/W Control Serial Electrically Erasable PROM with a voltage range of 4.5V to 5.5V. The device is organized as a single block of 256x8-bit memory with a 2-wire serial interface. Low-current design permits operation with typical standby and active currents of only 10 A and 1 mA, respectively. The device has a page write capabil- ity for up to 16 bytes of data and has fast write cycle times of only 1 ms for both byte and page writes. Functional address lines allow the connection of up to eight 24C02C devices on the same bus for up to 16K bits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (3.90 mm), 8-pin 2x3 DFN, 8-pin MSOP and TSSOP packages. 2 I C is a trademark of Philips Corporation. 2007 Microchip Technology Inc.
