A double cell structure provides a failsafe method of data reliability, while a double reset function prevents data miswriting. In addition, gold pads and gold wires are used for internal connections, pushing the boundaries of reliability to the limit. BR24L-W Series assort 1Kbit64Kbit. BR24S-W Series are possible to operate at high speed in low voltage and assort 16Kbit256Kbit.

Features 2 Completely conforming to the world standard I 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 1.8V~5.5V single power source action most suitable for battery use Page write mode useful for initial value write at factory shipment Highly reliable connection by Au pad and Au wire Auto erase and auto end function at data rewrite Low current consumption *2 At write operation (5V) : 1.2mA (Typ.) At read operation (5V) : 0.2mA (Typ.) At standby operation (5V) : 0.1A (Typ.) Write mistake prevention function Write (write protect) function added Write mistake prevention function at low voltage *3 SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J/VSON008X2030 compact package Data rewrite up to 1,000,000 times Data kept for 40 years Page write Noise filter built in SCL / SDA terminal Number of Shipment data all address FFh 8Byte 16Byte 32Byte Pages *1 BR24L02-WBR24L16-WBR24L32-W : 1.75.5V BR24L04-W Product BR24L01A-W BR24L32-W *2 BR24L32-WBR24L64-W : 1.5mA BR24L08-W number BR24L02-W BR24L64-W *3 Refer to following list BR24L16-W BR24L series Power source VSON008 Capacity Bit format Type SOP8 SOP-J8 SSOP-B8TSSOP-B8 MSOP8 TSSOP-B8J Voltage X2030 1Kbit 1288 BR24L01A-W 1.85.5V 2Kbit 2568 BR24L02-W 1.75.5V 4Kbit 5128 BR24L04-W 1.85.5V 8Kbit 1K8 BR24L08-W 1.85.5V 16Kbit 2K8 BR24L16-W 1.75.5V 32Kbit 4K8 BR24L32-W 1.75.5V 64Kbit 8K8 BR24L64-W 1.85.5V 2/32
