Description:
The Microchip Technology Inc. 24AA014/24LC014 is a 1 Kbit Serial Electrically Erasable PROM with operation down to 1.8V. The device is organized as a single block of 128 x 8-bit memory with a 2-wire serial interface. Low-current design permits operation with typical standby and active currents of only 1 A and 1 mA, respectively. The device has a page write capability for up to 16 bytes of data. Functional address lines allow the connection of up to eight 24AA014/24LC014 devices on the same bus for up to 8 Kbits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (150 mil), TSSOP, 2x3 DFN and MSOP packages.
