Description:
The Microchip Technology Inc. 24AA014/24LC014 is a
1 Kbit Serial Electrically Erasable PROM with opera-
tion down to 1.7V. 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 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 TDFN and MSOP packages. The 24AA014/
24LC014 is also available in the 6-lead SOT-23
package.
