Description
BR24L††-W series is a serial EEPROM of I²C BUS interface method.
Features
y Completely conforming to the world standard I²C BUS. All controls available by 2 ports of serial clock (SCL) and serial data (SDA)
y Other devices than EEPROM can be connected to the same port, saving microcontroller port
y 1.8 ~ 5.5V^*1 single power source action most suitable for battery use
y Page write mode useful for initial value write at factory shipment
y Highly reliable connection by Au pad and Au wire
y Auto erase and auto end function at data rewrite
y Low current consumption
At write action (5V) : 1.2mA (Typ.)^*2
At read action (5V) : 0.2mA (Typ.)
At standby action (5V) : 0.1µA (Typ.)
y Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
y SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J compact package ^{*3 *4}
y Data rewrite up to 1,000,000 times
y Data kept for 40 years
y Noise filter built in SCL / SDA terminal
Page write
y Shipment data all address FFh
