CAT25256XI-T2 Description

Short technical summary and product information.

The CAT25256XI-T2 from ON Semiconductor is a 256Kb Serial EEPROM device that utilizes the SPI protocol for communication. Internally organized as 32K x 8 bits, it features a 64-byte page write buffer and supports SPI modes (0,0) and (1,1). The device operates within a wide supply voltage range of 1.8V to 5.5V and can achieve clock frequencies up to 20 MHz.

 

This EEPROM offers robust write protection mechanisms, including both hardware and software controls, allowing for partial or full array protection. It also includes an additional identification page with permanent write protection. Designed for reliability, the CAT25256XI-T2 incorporates on-chip ECC (Error Correction Code) and boasts 1,000,000 program/erase cycles with 100 years of data retention.

 

The CAT25256XI-T2 is available in an 8-lead SOIC package, suitable for surface mounting. It operates across an industrial and extended temperature range of -40°C to 85°C (TA). The device is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.
