24LC32

12.3.1. General Description

The Microchip Technology Inc. 24AA32A/24LC32A(24XX32A*) is a 32 Kbit Electrically Erasable PROM. The
device is organized as four blocks of 8K x 8-bitmemory with a 2-wire serial interface. Low-voltage design
permits operation down to 1.8V, with standby and active currents of only 1μA and 1mA, respectively. It has
been developed for advanced, low-power applications such as personal communications or data acquisition.
The 24XX32A also has a page write capability for up to 32 bytes of data. Functional address lines allow up to
eight devices on the same bus, for up to 256Kbits address space.
