Microchip 93C56B-E/SN: A Robust 16-Bit 2K Serial EEPROM Solution

The Microchip 93C56B-E/SN is a 2K-bit, serial-accessible Electrically Erasable PROM (EEPROM) organized as 128 x 16-bit. This device is engineered for applications requiring non-volatile memory storage with high reliability and low power consumption. Housed in a compact 8-lead SOIC package, it is ideally suited for space-constrained environments across automotive, industrial, and consumer electronics.

A key feature of this EEPROM is its wide voltage operation range (1.8V to 5.5V), enabling seamless integration into both 3.3V and 5V systems without the need for level shifters. This flexibility is crucial for designing versatile and future-proof products. The device supports a simple and efficient 3-wire serial interface (CS, SK, DI/DO), facilitating easy communication with a host microcontroller while minimizing pin count on the controller itself.

The 93C56B-E/SN offers both read and write operations with a byte/word programming capability. It includes essential self-timed write cycles and built-in erase/write protection mechanisms, which prevent inadvertent data corruption. With an endurance of 1 million erase/write cycles and data retention exceeding 200 years, this EEPROM ensures long-term data integrity and reliability in the most demanding applications. Its industrial temperature range (-40°C to +85°C) further guarantees stable performance under harsh operating conditions.

ICGOODFIND: The Microchip 93C56B-E/SN stands out as a highly reliable and flexible serial EEPROM solution. Its combination of a wide voltage range, robust endurance, and compact form factor makes it an excellent choice for designers seeking dependable non-volatile memory.
