The AT93C56SC from Microchip Technology is a high-performance, serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device, designed to provide a robust storage solution for a wide range of applications. This EEPROM offers a storage capacity of 2K (2,048 bits) and utilizes the industry-standard Serial Peripheral Interface (SPI) for communication, making it an ideal choice for embedded systems that require a reliable non-volatile memory.

The device operates over a voltage range of 2.7V to 5.5V, which enables compatibility with both 3.3V and 5V systems, ensuring it can be integrated into various circuit designs without additional level shifting. The AT93C56SC is optimized for low-power consumption, making it suitable for battery-operated and power-sensitive applications.

Featuring a self-timed write cycle, the AT93C56SC includes an automatic erase-before-write capability, ensuring data integrity and simplifying the programming process. The write cycle is completed within 5 ms, providing efficient write operations. Additionally, the device supports a write protect feature, which can be activated via a dedicated pin to prevent accidental data alteration.

The AT93C56SC comes in a compact 8-lead SOIC package, which is suitable for space-constrained applications. It is also available in other package options to cater to different design requirements. The device is designed to withstand harsh operating conditions and is rated for an industrial temperature range of -40°C to +85°C.

Microchip's AT93C56SC EEPROM is a versatile memory component that is well-suited for applications such as parameter storage, device configuration, and identification, where small amounts of non-volatile memory are essential. The combination of high-reliability, low-power operation, and industry-standard interface makes it a preferred choice for designers looking to enhance their systems with a dependable memory solution.
