Description

The Microchip Technology Inc. 24AA32A/24LC32A (24XX32A*) is a 32 Kbit Electrically Erasable PROM. The device is organized as a single block of 4K 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. It has been developed for advanced, lowpower applications such as personal communicationsor data acquisition. The 24AA32A/24LC32A  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, 2x3 DFN and MSOP packages.

The Microchip Technology Inc. 24AA32A/24LC32A  is a 4K x 8 (32K bit) Serial Electrically Erasable PROM in an ISO micromodule for use in smart card applications. 24AA32A/24LC32A has a page-write capability of up to 32 bytes.
