93C46N, 1Kbit Serial EEPROM, MICROWIRE Interface,DIP-8

The 93C46N is a 1Kbit Serial EEPROM designed for low-power, high-reliability applications requiring non-volatile storage. It supports a MICROWIRE-compatible (3-wire SPI) interface, making it ideal for use in microcontroller-based designs, embedded systems, and industrial control applications.

With flexible memory organization, the 93C46N can be configured as 128 x 8-bit or 64 x 16-bit, allowing designers to optimize for byte-based or word-based storage. It supports self-timed erase/write cycles with an automatic erase-before-write function, ensuring efficient and secure data storage.

Operating at 4.5V to 5.5V, this EEPROM provides reliable data retention of over 200 years, and endurance for 1,000,000 erase/write cycles. Built-in Erase/Write Enable (EWEN) and Disable (EWDS) commands prevent accidental overwriting, making it highly secure for firmware, configuration data, and calibration storage.

Encased in a DIP-8 package, the 93C46N is an excellent choice for consumer electronics, automotive applications, and industrial automation where reliable non-volatile memory is required.
