BR24L□□-W Series
●Description
2
BR24L□□-W series is a serial EEPROM of I C BUS interface method.
●Features
2
1) Completely conforming to the world standard I C 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
*1
3) 1.8V~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
*2
At write operation (5V)
: 1.2mA (Typ.)
At read operation (5V)
: 0.2mA (Typ.)
At standby operation (5V) : 0.1μA (Typ.)
8) Write mistake prevention function
Write (write protect) function added
9) Write mistake prevention function at low voltage
10) SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J/VSON008X2030 compact package
*3
11) Data rewrite up to 1,000,000 times
12) Data kept for 40 years
13) Noise filter built in SCL / SDA terminal
14) Shipment data all address FFh
