●Description
BR24T□□□-W series is a serial EEPROM of I
2
C BUS interface method
●Features
・ Completely conforming to the world standard I
2
C BUS. All controls available by 2 ports of serial clock(SCL) and serial
data(SDA)
・ Other devices than EEPROM can be connected to the same port, saving microcontroller port
・ 1.7V～5.5V single power source action most suitable for battery use
・ 1.7V～5.5Ｖwide limit of action voltage, possible FAST MODE 400KHz action
・ Page write mode useful for initial value write at factory shipment
・ Auto erase and auto end function at data write
・ Low current consumption
・ Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
・ DIP-T8/SOP8/SOP-J8/SSOP-B8/TSSOP-B8/TSSOP-B8J/MSOP8/VSON008X2030 compact package
・ Data rewrite up to 1,000,000 times
・ Data kept for 40 years
・ Noise filter built in SCL / SDA terminal
・ Shipment data all address FFh
