High Reliability Series
EEPROMs I2C BUS
BR24A□□-WM series
No.09001ECT02
●Description
BR24A□□-WM series is a serial EEPROM of I²C BUS interface method.
●Features
1) Completely conforming to the world standard I²C BUS. All controls available by 2 ports of serial clock(SCL) and serial data(SDA)
2) Other devices than EEPROM can be connected to the same port, saving microcontroller port
3) 2.5V~5.5V single power source action most suitable for battery use
4) Page write mode useful for initial value write at factory shipment
5) Highly reliable connection by Au pad and Au wire
6) Auto erase and auto end function at data rewrite
7) Low current consumption
At write operation (5V)
: 1.2mA (Typ.) ^*1
At read operation (5V)
: 0.2mA (Typ.)
At standby operation (5V) : 0.1μA (Typ.)
8) Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
9) SOP8/SOP-J8/MSOP8 compact package ^*2
10) Data rewrite up to 100,000 times
11) Data kept for 40 years
12) Noise filter built in SCL / SDA terminal
13) Shipment data all address FFh
