I²C BUS
BR24□□□□family
BR24T□□□□Series
No.11001EAT21
●Description
BR24T□□□-W 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) 1.7V～5.5V single power source action most suitable for battery use
4) 1.7V～5.5Vwide limit of action voltage, possible FAST MODE 400KHz action
5) Page write mode useful for initial value write at factory shipment
6) Auto erase and auto end function at data write
7) Low current consumption
8) Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
9) DIP-T8/SOP8/SOP-J8/SSOP-B8/TSSOP-B8/TSSOP-B8J/MSOP8/VSON008X2030 various packages
10) Data rewrite up to 1,000,000 times
11) Data kept for 40 years
12) Noise filter built in SCL / SDA terminal
13) Shipment data all address FFh
