Microchip Technology 93LC56T-I/SN EEPROM

The Microchip Technology 93LC56T-I/SN is a 2Kb (256 x 8 or 128 x 16) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device that provides an efficient non-volatile data storage solution for a wide range of applications. This particular model comes in an 8-pin SOIC (Small Outline Integrated Circuit) package, ensuring a compact footprint for space-constrained applications.

This EEPROM device operates with a voltage range of 2.5V to 5.5V, making it compatible with most low-power and standard power applications. It is designed to support the Serial Peripheral Interface (SPI) bus, which allows for simple integration into existing designs and is known for its high-speed data transfer capabilities.

One of the key features of the 93LC56T-I/SN is its self-timed erase and write cycles, which include an auto-erase function before each write operation. This feature simplifies the programming process and ensures data integrity. Additionally, the device supports a write cycle time of 5 ms, providing efficient performance for write operations.

The EEPROM also incorporates a hardware write-protect pin, which provides an additional layer of security to prevent accidental data overwrites. This is particularly useful in applications where data integrity is paramount. The 93LC56T-I/SN also includes a status register for write cycle monitoring, allowing for better control over the write operations.

Designed for reliability, the device offers a write endurance of 1 million cycles and a data retention period of over 200 years, ensuring the longevity and durability of the data stored. The operating temperature range of -40°C to +85°C makes the 93LC56T-I/SN suitable for industrial applications that may be exposed to extreme environmental conditions.

In summary, the Microchip Technology 93LC56T-I/SN is a versatile and reliable EEPROM that provides efficient non-volatile memory storage with a small form factor, SPI compatibility, and robust data protection features, making it an excellent choice for a variety of electronic applications.
