The Microchip Technology Inc. 24AA08H/24LC08BH
(24XX08H*) is an 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 μA and 1 mA,

Note 1: 100 kHz for VCC <2.5V
respectively. The 24XX08H also has a page write
capability for up to 16 bytes of data. The 24XX08H is
available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP, 2x3 TDFN and MSOP packages, and
is also available in the 5-lead SOT-23 package. All
packages are Pb-free and RoHS compliant.
