The Microchip Technology Inc. 24AA08/24LC08B(24XX08*) is a 8 Kbit Electrically Erasable PROM. Thedevice is organized as four blocks of 256 x 8-bitmemory with a 2-wire serial interface. Low-voltagedesign permits operation down to 1.7V, with standbyand active currents of only 1 A and 1 mA,respectively. The 24XX08 also has a page writecapability for up to 16 bytes of data. The 24XX08 isavailable in the standard 8-pin PDIP, surface mountSOIC, TSSOP, 2x3 DFN, 2x3 TDFN and MSOPpackages, and is also available in the 5-lead SOT-23package. All packages are Pb-free and RoHScompliant.
