Microchip Technology, Inc. Memory 24LC32AX-I/ST

The 24LC32AX-I/ST is a 32 Kbit Electrically Erasable PROM from Quarktwin Technology Ltd., designed for low-power applications. It operates on a single supply voltage ranging from 1.8V to 5.5V, with a low active current of 1 mA and a standby current of 1 OºA. The device features a 2-wire I¬=C compatible serial interface, allowing for easy integration into various systems. It supports a maximum clock frequency of 400 kHz and can be cascaded to connect up to eight devices, providing a total addressable space of 256 Kbits. The memory is organized as a single block of 4K bytes and includes a page write buffer capable of handling up to 32 bytes of data. It also features hardware write protection for the entire memory and self-timed write cycles, including auto-erase functionality. The device is available in multiple package types, including 8-lead PDIP, SOIC, TSSOP, DFN, and MSOP, and is offered in both industrial and automotive temperature ranges, from -40¬8C to +85¬8C and -40¬8C to +125¬8C, respectively. The 24LC32AX-I/ST is suitable for applications requiring high endurance, with a write cycle endurance of 1,000,000 cycles and data retention exceeding 200 years.
