The AT24C256C-SSHL-B is a 256Kb (32,768 x 8) Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) manufactured by Microchip Technology. This high-density non-volatile memory device utilizes the industry-standard two-wire I²C interface, making it an ideal choice for applications that require efficient data storage and retrieval without the need for frequent or fast changes.

With a voltage range of 2.5V to 5.5V, the AT24C256C-SSHL-B provides designers with flexibility for various system voltage levels. This EEPROM is capable of both byte and page write, with the page size being 64 bytes. The fast write cycle times of 5 ms max for both page and byte write operations ensure high performance and efficient system behavior.

One of the key features of this device is its extended temperature range, which makes it suitable for industrial applications, where operations under extreme conditions are a common requirement. The device operates reliably across a temperature range of -40°C to +85°C.

The AT24C256C-SSHL-B also offers a self-timed write cycle with auto-clear, which simplifies the write operation and reduces the need for software polling. This is complemented by a write protect feature that provides hardware data protection. The entire memory can be protected by setting the write protect pin to ground.

For security and data integrity, the EEPROM includes a 32-byte page write buffer, which allows for faster data write operations. Additionally, the device supports a random and sequential read mode, which provides flexible data retrieval options for various application needs.

In terms of packaging, the AT24C256C-SSHL-B comes in an 8-lead SOIC package, which is widely accepted in the industry and suitable for standard PCB assembly processes. This product is lead-free and RoHS compliant, adhering to environmental standards for electronic components.

Whether you're designing consumer electronics, automotive systems, or complex industrial machinery, the Microchip Technology AT24C256C-SSHL-B EEPROM offers a reliable and versatile solution for your non-volatile memory needs.
