CAT25256YI-G Description

Short technical summary and product information.

The CAT25256YI-G from On Semiconductor is a 256-kilobit Serial Peripheral Interface (SPI) EEPROM. It is internally organized as 32Kx8 bits and features a 64-byte page write buffer. This device supports SPI modes (0,0) and (1,1) and operates with a supply voltage range of 1.8 V to 5.5 V, with a maximum clock frequency of 20 MHz.

 

Key features include hardware and software write protection, block write protection for 1/4, 1/2, or the entire array, and an additional identification page with permanent write protection. The device is built using low-power CMOS technology, offering 1,000,000 program/erase cycles and 100 years of data retention. On-chip ECC makes it suitable for high-reliability applications.

 

The CAT25256YI-G is available in an 8-lead TSSOP package, designed for surface mounting. It operates within an industrial and extended temperature range of -40°C to +85°C (TA). The device also offers robust ESD performance, with 2 kV Human Body Model and 1 kV Charged Device Model protection.
