The BR25G256FJ-3GE2 is a 256Kbit EEPROM manufactured by ROHM that operates over an SPI bus. Its features include a low power consumption, a wide operating voltage range from 2.2V to 5.5V, and a programmable write protection for up to 16Kbytes. The access time is 20µs, and the write cycle time is 70µs. The device is capable of over 10,000 write/erase cycles, making it highly reliable for in-system applications. It also includes error correction and on-chip programming verification, reducing the amount of time and effort required for programming. This EEPROM is ideal for use in applications requiring a small and low-power non-volatile memory.
