BR24L08-W

TECHNICAL NOTE HIGH GRADE Specification HIGH RELIABILITY series I2C BUS Serial EEPROMs Supply voltage 1.8V~5.5V Operating temperature –40°C~+85°C type BR24L01A-W, BR24L02-W, BR24L04-W, BR24L08-W, BR24L16-W, BR24L32-W, BR24L64-W Description BR24L -W series is a serial EEPROM of I2C BUS interface method. Features Completely conforming to the world standard I2C 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 1.8 ~ 5.5V*1 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 At write action (5V) : 1.2mA (Typ.)*2 At read action (5V) : 0.2mA (Typ.) At standby action (5V) : 0.1µA (Typ.) Write mistake prevention function Write (write protect) function added Write mistake prevention function at low voltage SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J compact package *3 *4 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 *1 *2 *3 *4 BR24L16-W, BR24L32-W : 1.7~5.5V BR24L32-W, BR24L64-W: 1.5mA BR24L32-W: SOP8/SOP-J8/ SSOP-B8/TSSOP-B8 BR24L64-W: SOP8/SOP-J8 pages 8 Byte 16 Byte 32 Byte Product number BR24L01A-W BR24L02-W BR24L04-W BR24L08-W BR24L16-W BR24L32-W BR24L64-W BR24L series Capacity 1Kbit 2Kbit 4Kbit 8Kbit 16Kbit 32Kbit 64Kbit Bit format 128 × 8 256 × 8 512 × 8 1K × 8 2K × 8 4K × 8 8K × 8 Type BR24L01A-W BR24L02-W BR24L04-W BR24L08-W BR24L16-W BR24L32-W BR24L64-W Power source voltage SOP8 SOP-J8 SSOP-B8 TSSOP-B8 MSOP8 TSSOP-B8J 1.8 ~ 5.5V 1.8 ~ 5.5V 1.8 ~ 5.5V 1.8 ~ 5.5V 1.7 ~ 5.5V 1.7 ~ 5.5V 1.8 ~ 5.5V Ver.B Oct.2005 Absolute maximum ratings (Ta=25˚C) Parameter Impressed voltage Recommended action conditions Parameter Symbol Power source voltage Input voltage Memory cell characteristics (Ta = 25˚C, Vcc = 1.8 ~ 5.5V)*1 Parameter Number of data rewrite times Data hold years *2 *2 Symbol Limits Unit Limits Unit *1 Limits VCC -0.3 ~ +6.5 V *1 *2 *3 *4 *5 VCC VIN 1.8 ~ 5.5 0 ~ VCC V V Min. 1,000,000 40 Typ. - Max. - Unit Times Years 450 (SOP8) 450 (SOP-J8) Permissible dissipation *1 BR24L16/L32-W : 1.7~5.5V Pd 300 (SSOP-B8) 330 (TSSOP-B8) 310 (MSOP8) mW Shipment data all address FFh *1 BR24L16/L32-W : 1.7~5.5V *2 Not 100% TESTED 310 (TSSOP-B8J) *6 Storage temperature range Action temperature range Tstg Topr - -65 ~ +125 -40 ~ +85 -0.3 ~ VCC+1.0 ˚C ˚C V Terminal voltage * When using at Ta = 25°C or higher, 4.5mW (*1, *2), 3.0mW (*3), 3.3mW (*4) 3.1mW (*5,*6) to be reduced per 1°C Action timing characteristics *1 SCL frequency Data clock "HIGH" time Data clock "LOW" time SDA,SCL rise time SDA,SCL fall time *2 *2 Electrical characteristics Parameter "HIGH" input voltage 1 "LOW" input voltage 1 "HIGH" input voltage 2 "LOW" input voltage 2 "HIGH" input voltage 3 *3 "HIGH" input voltage 3 *4 "LOW" input voltage 3 *2 "LOW" output voltage 1 "LOW" output voltage 2 Input leak current Output leak current Symbol VIH1 VIL1 VIH2 VIL2 VIH3 VIH3 VIL3 VOL1 VOL2 ILI ILO ICC1 ICC2 Standby current ISB Min. 0.7VCC -0.3 *2 0.8VCC -0.3 *2 0.8VCC 0.9VCC -0.3 -1 -1 Limits Typ.
