Microchip Technology's 93LC56AT/SN EEPROM

The 93LC56AT/SN is a high-quality EEPROM (Electrically Erasable Programmable Read-Only Memory) device produced by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This particular EEPROM offers a reliable and convenient way to store data in a non-volatile format, meaning the information is retained even when the power is turned off.

Designed with versatility in mind, the 93LC56AT/SN provides a storage capacity of 2 Kbits, organized as 128 x 16-bit words when using the word addressing mode, or as 256 x 8-bit words in byte mode. This flexibility allows developers to select the most appropriate data granularity for their specific application requirements.

The device operates over a standard voltage range of 2.5V to 5.5V, making it suitable for a wide array of applications from industrial to consumer electronics. It features a self-timed erase and write cycles, including auto-erase and auto-write functions, which simplifies the task of managing data storage and reduces the overhead for the host microcontroller.

One of the key advantages of the 93LC56AT/SN is its serial interface, which minimizes the number of I/O lines used, thus reducing the overall design footprint and complexity. This serial EEPROM utilizes the industry-standard 3-wire serial communication protocol, which includes Chip Select, Data In (DI), Data Out (DO), and Clock (CLK) pins, making it compatible with a vast range of microcontrollers and other digital systems.

For added reliability, the 93LC56AT/SN features a write protect pin to prevent inadvertent writes, which can be crucial in applications where data integrity is paramount. Additionally, the device is specified for a high endurance of one million erase/write cycles and a data retention period of over 200 years, ensuring the longevity and durability of the stored information.

Available in an 8-pin SN (SOIC) package, the 93LC56AT/SN is a practical choice for applications that require a compact, reliable, and low-power solution for data storage. Whether used in automotive systems, medical devices, or consumer electronics, this EEPROM from Microchip Technology offers a trusted option for maintaining critical data across power cycles.
