Microchip 93LC56BT-E/MNY: A 2K SPI Microwire Serial EEPROM Overview

The Microchip 93LC56BT-E/MNY is a 2K-bit Serial Electrically Erasable PROM (EEPROM) designed for reliable non-volatile data storage in a wide range of applications. Organized as 128 x 8-bit or 64 x 16-bit, this memory IC provides a flexible solution for storing configuration parameters, calibration data, and other critical information in systems where space and power are at a premium.

Housed in a compact 8-pin DFN package, this device is ideal for space-constrained designs. It operates over a broad voltage range (1.8V to 5.5V), making it suitable for both low-power battery-operated devices and robust 5V systems. Its low power consumption characteristics further enhance its appeal for portable and energy-sensitive applications.

A key feature of the 93LC56BT-E/MNY is its compatibility with two popular serial protocols: the Microchip Microwire® synchronous serial interface and the broader SPI (Serial Peripheral Interface). This dual-protocol support offers designers significant flexibility, allowing the chip to interface seamlessly with a vast array of microcontrollers and processors without requiring additional glue logic. The interface includes dedicated pins for Chip Select (CS), Serial Clock (SK), Data Input (DI), and Data Output (DO).

The EEPROM boasts a suite of features that ensure data integrity and longevity. It supports both byte-level and page-level write operations, granting firmware engineers efficient control over how data is stored. The memory array is rated for 1,000,000 erase/write cycles and offers 200 years of data retention, ensuring that stored information remains intact for the lifetime of the end product. Furthermore, it includes built-in hardware and software write protection schemes to prevent accidental data corruption.

Typical applications for the 93LC56BT-E/MNY are extensive, spanning across industries. It is commonly found in automotive electronics, industrial control systems, telecommunications hardware, consumer electronics, and medical devices.
