C BUS EEPROM (2-Wire)
BR24Axxx-WM
(1K 2K 4K 8K 16K 32K 64K)
●General
Description
BR24Axxx-WM 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)
Wide temperature range -40℃ to +105℃
Other devices than EEPROM can be connected to
the same port, saving microcontroller port
2.5V to 5.5V single power source operation most
suitable for battery use
Page write mode useful for initial value write at
factory shipment
Auto erase and auto end function at data rewrite
Low current consumption
At write operation (5V)
: 1.2mA (Typ.)
*1
At read operation (5V)
: 0.2mA (Typ.)
At standby condition (5V) : 0.1μA (Typ.)
Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
Data rewrite up to 1,000,000 times(Ta≦25℃)
Data kept for 40 years(Ta≦25℃)
Noise filter built in SCL / SDA terminal
Shipment data all address FFh
