BR24G256FJ-3AGTE2

ROHM  BR24G256FJ-3AGTE2  EEPROM, 256 Kbit, 32K x 8位, 1 MHz, 串行 I2C, SOP, 8 引脚

The is a 256kB 2-wire I²C bus Electrically Erasable Programmable Read-Only Memory EEPROM with 1.7 to 5.5V wide Limit of operating voltage, possible fast mode 1MHz operation. It features single power source operation most suitable for battery use. It is also features all controls available by 2 ports of serial clock SCL and serial data SDA and other devices than EEPROM can be connected to the same port, saving microcontroller port.
