Description

The Microchip Technology Inc. 24AA02/24LC02B (24XX02*) is a 2 Kbit Electrically Erasable PROM. 24LC02B is organized as one block 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 24XX02 also has a page write capability for up to 8 bytes of data. The 24XX02 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages and is also available in the 5-lead SOT-23 package.

The Microchip Technology Inc. 24LC01B and 24LC02B are 1K-bit and 2K-bit Electrically Erasable PROMs in ISO modules for smart card applications. The devices are organized as a single block of 128 x 8-bit or 256 x 8-bit memory with a two-wire serial interface. The 24LC01B and 24LC02B also have page-write capability for up to 8 bytes of data.
