Microchip 93LC56C-I/SN: A Compact 1K 5V Serial EEPROM for Embedded Systems

The Microchip 93LC56C-I/SN is a highly reliable 1K-bit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for a wide range of industrial, automotive, and consumer applications. Organized as 128 x 8-bit, this non-volatile memory IC provides a robust solution for storing critical data such as configuration parameters, calibration constants, and user settings in microcontroller-based systems.

Operating from a single 5V power supply, the 93LC56C supports a simple and efficient 3-wire serial interface (CS, SK, DI/DO), making it easy to interface with a vast array of microcontrollers and digital logic circuits. Its sequential read operation allows for efficient data streaming, enhancing overall system performance. The device features both software and hardware write protection mechanisms to prevent accidental data corruption, ensuring the integrity of stored information.

Housed in a space-saving 8-lead SOIC (SN) package, this EEPROM is ideal for applications where board real estate is at a premium. It offers a high level of endurance, capable of 1,000,000 erase/write cycles, and boasts a data retention period of over 200 years, underlining its exceptional reliability for long-term deployments. Its extended industrial temperature range (-40°C to +85°C) ensures stable operation in harsh environments.

ICGOOODFIND: The 93LC56C-I/SN stands out as a versatile and durable serial EEPROM, offering an optimal blend of simplicity, density, and reliability for modern embedded designs requiring non-volatile memory.
