The Microchip 93LC86T-I/SN: A Robust 16K-Bit Serial EEPROM Solution

In the realm of non-volatile memory, serial EEPROMs remain a fundamental component for storing critical configuration, calibration, and data-logging information across a vast array of applications. The Microchip 93LC86T-I/SN stands out as a reliable and versatile solution, offering 16K bits of organized memory in a compact SOIC package. This device is engineered to provide a seamless blend of performance, durability, and ease of integration, making it a preferred choice for designers.

A key feature of the 93LC86T-I/SN is its wide voltage operation range (2.5V to 7.0V), which ensures robust performance even in electrically noisy environments or systems with fluctuating power supplies. This high maximum voltage rating is particularly advantageous in industrial and automotive applications where reliability is paramount. The memory is organized as 1024 x 16 bits, allowing for efficient storage of larger data words and simplifying software management.

Communication is handled via a simple and ubiquitous 3-wire serial interface (CS, SK, DI/DO), which minimizes the number of microcontroller I/O pins required, making it ideal for space-constrained PCB designs. The device supports a comprehensive instruction set, enabling full read, write, erase, and write-enable/disable operations. Furthermore, it features built-in write protection mechanisms, including both software and hardware data protection, to prevent accidental data corruption.

The 93LC86T-I/SN is designed for endurance, supporting over 1 million erase/write cycles and boasting a data retention period of more than 200 years. This exceptional longevity guarantees the integrity of stored information over the entire lifespan of the end product. Its commercial temperature range (0°C to +70°C) ensures stable operation in most common use cases.

Typical applications are extensive, ranging from storing calibration tables in medical devices and metering equipment to preserving user settings in consumer electronics and automotive modules. Its serial interface and small form factor also make it perfect for integration into smart sensors, modules, and other peripheral boards.
