Description:

The Microchip Technology Inc. 24AA014/24LC014 is a

1 Kbit Serial Electrically Erasable PROM with opera-

tion down to 1.8V. The device is organized as a single

block of 128 x 8-bit memory with a 2-wire serial inter-

face. Low-current design permits operation with typical

standby and active currents of only 1 μA 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 TDFN and MSOP packages.
