Description:
The Microchip Technology Inc. 24AA014H/24LC014H
is a 1 Kbit Serial Electrically Erasable PROM with
operation down to 1.7V. 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
maximum standby and active currents of only 1 μA and
400 μA, 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 24AA014H/
24LC014H 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 TDFN and MSOP packages.
