Microchip 93C86CT-E/MS 16Kb Microwire Serial EEPROM: Features and Applications

The Microchip 93C86CT-E/MS is a 16-Kilobit (1024 x 16 or 2048 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) that utilizes the reliable Microwire serial interface. Housed in an 8-pin MSOP package, this device is engineered for high-performance, non-volatile data storage in a wide array of embedded systems. Its combination of density, durability, and a simple communication protocol makes it a versatile solution for numerous applications.

A key feature of this EEPROM is its Microwire synchronous serial interface, which requires only three signal lines for communication: Chip Select (CS), Serial Clock (SK), and Data Input (DI) and Output (DO). This simplicity reduces the number of I/O pins required from the host microcontroller, making it ideal for space-constrained designs. The device supports a wide voltage range from 2.5V to 5.5V, enabling operation across various logic levels and power environments, from battery-powered devices to main-powered systems.

The 93C86CT-E/MS offers impressive reliability with a endurance of 1 million erase/write cycles and data retention of over 200 years. This ensures data integrity over the entire lifespan of the end product. It also features both software and hardware write-protection mechanisms, safeguarding critical memory blocks from accidental corruption. The organization's flexibility, allowing operation in either 8-bit or 16-bit word length, provides designers with configuration options to optimize for code or data storage efficiency.

Applications of the 93C86CT-E/MS are extensive. It is commonly used for storing calibration data, configuration settings, and identity information in automotive electronics such as dashboards and sensors. In consumer electronics, it serves in set-top boxes, televisions, and appliances for preserving user preferences. Furthermore, it is a staple in industrial control systems for parameter storage and in telecommunications equipment. Its small MSOP package makes it particularly suitable for portable and miniaturized devices where board space is at a premium.

ICGOODFIND: The Microchip 93C86CT-E/MS stands out as a robust, high-density non-volatile memory solution. Its simple 3-wire interface, exceptional endurance and retention, and flexible organization make it an excellent choice for designers seeking reliable memory across automotive, industrial, and consumer applications.
