● Description
BR25L□□□-W series is a serial EEPROM of SPI BUS interface method.
Features
● High speed clock action up to 5MHz (Max.)
● Wait function by HOLD terminal
● Part or whole of memory arrays settable as read only memory area by program
● 1.8 ~ 5.5V single power source action most suitable for battery use
● Page write mode useful for initial value write at factory shipment
● Highly reliable connection by Au pad and Au wire
● For SPI bus interface (CPOL, CPHA) = (0, 0), (1, 1)
● Auto erase and auto end function at data rewrite
● Low current consumption
At write action (5V) : 1.5mA (Typ.)
At read action (5V) : 1.0mA (Typ.)
At standby action (5V) : 0.1μA (Typ.)
Page write
● Address auto increment function at read action
● Write mistake prevention function
