Datasheet Serial EEPROM Series Automotive EEPROM 125℃ Operation SPI BUS EEPROM BR25H040-2C ●General Description BR25H040-2C is a serial EEPROM of SPI BUS interface method. ●Features „ High speed clock action up to 10MHz (Max.) „ Wait function by HOLDB terminal. „ Part or whole of memory arrays settable as read only memory area by program. „ 2.5V to 5.5V single power source action most suitable for battery use. „ Page write mode useful for initial value write at factory shipment. „ For SPI bus interface (CPOL, CPHA)=(0, 0), (1, 1) „ Self-timed programming cycle. „ Low Supply Current At write operation (5V) : 1.0mA (Typ.) At read operation (5V) : 1.0mA (Typ.) At standby operation (5V) : 0.1μA (Typ.) „ Address auto increment function at read operation „ Prevention of write mistake Write prohibition at power on. Write prohibition by command code (WRDI). Write prohibition by WPB pin. Write prohibition block setting by status registers (BP1, BP0). Pre...
