The Microchip Technology Inc. 24AA08/24LC08B
(24XX08*) is a 8 Kbit Electrically Erasable PROM. The
device is organized as four blocks of 256 x 8-bit
memory with a 2-wire serial interface. Low-voltage
design permits operation down to 1.7V, with standby
and active currents of only 1 A and 1 mA, respectively.
The 24XX08 also has a page write capability for up to
16 bytes of data. The 24XX08 is available in the
standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3
DFN, 2x3 TDFN and MSOP packages, and is also
available in the 5-lead SOT-23, or 4-lead Chip Scale
package. All packages are Pb-free and RoHS
compliant.
