MICROCHIP 93C46B-I/SN 1Kbit Serial EEPROM, SOIC-8 Package

The MICROCHIP 93C46B-I/SN is a 1 kilobit (1Kbit) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for reliable, non-volatile data storage. Utilising advanced CMOS technology, this device is ideal for applications demanding low power consumption and robust performance. It is compatible with the MICROWIRE serial interface, providing a simple and efficient three-wire connection for communication with microcontrollers and other logic devices.

This EEPROM features a memory configuration of 64 words by 16 bits and supports a maximum clock frequency of 3 MHz. Key operational benefits include self-timed erase and write cycles, which simplify programming, and an automatic 'erase all' (ERAL) function that precedes a 'write all' (WRAL) operation for batch programming. Built-in power-on and power-off data protection circuitry safeguards your stored information against corruption during voltage transitions.
