MICROCHIP 93C46B/P 1Kbit Serial EEPROM DIP8

The MICROCHIP 93C46B/P is a 1Kbit MICROWIRE compatible serial Electrically Erasable Programmable Read-Only Memory (EEPROM) housed in an 8-pin DIP package. It utilises advanced low-power CMOS technology, making it an ideal choice for energy-efficient, nonvolatile memory applications. This device features self-timed erase and write cycles, enhancing operational efficiency.

Key functionalities include an automatic erase all (ERAL) before a write all (WRAL) operation, ensuring data integrity during bulk memory operations. Integrated power-on and power-off data protection circuitry safeguards stored information against corruption. The chip employs an industry-standard 3-wire serial I/O interface and provides a device status signal (ready/busy) for simple system integration.

Other notable features are a sequential read function, support for over 1,000,000 erase/write cycles, and exceptional data retention exceeding 200 years. The device is compatible with other word-selectable family members, such as the 93AA46C, 93LC46C, or 93C46C, which may require external logic to set the word size via the ORG pin. The 93C46B is dedicated to 16-bit communication.

With its robust specifications, including a wide operating voltage range and a temperature tolerance suitable for commercial environments, this EEPROM is a reliable and long-lasting solution for storing configuration data, calibration settings, or other critical information.
