●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-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.8V, with standby and active currents of only 1µA and 1 mA, 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 256 Kbits address space. The 24XX32A is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP and MSOP packages.
