Description
The Microchip Technology Inc. 24AA02E48/24AA025E48/24AA02E64/24AA025E64 (24AA02XEXX) is a 2 Kbit Electrically Erasable PROM. The device is organized as two blocks of 128 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.7V, with maximum standby currents of only 1 µA for I-Temp. and 5 µA for E-Temp., as well as a maximum active current of 1 mA. The 24AA02XEXX also has a page write capability for up to eight bytes of data (16 bytes on the 24AA025E48/24AA025E64). The 24AA02XEXX is available in the standard 8-pin SOIC, 5-lead SOT-23, and 6-lead SOT-23 packages.
