BU9847GUL-WE2

High Reliability Series Serial EEPROMs WL-CSP EEPROM family I2C BUS BU9847GUL-W No.10001EAT14 ●Description 2 BU9847GUL-W series is a serial EEPROM of I C BUS interface method. 1.7V single power source action and actions available at 400kHz. ●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. 3) Actions available at 400kHz clock (1.7V～5.5V) 4) 1.7～5.5V single power source action most suitable for battery use. 5) Page write mode useful for initial value write at factory shipment. 6) Auto erase and auto end function at data rewrite. 7) Low current consumption At write action (5V) : 1.2mA (Typ.) At read action (5V) : 0.2mA (Typ.) At standby action (5V) : 0.1μA (Typ.) 8) Write mistake prevention function ●Page write Write (write protect) function added. Write mistake prevention function at low voltage. Number of pages 16Byte 9) Data rewrite up to 1,000,000times. 10) Data kept for 40 years. Product number BU9847GUL-W 11) Noise filter built in SCL / SDA terminal 12) Shipment data all address FFh. ●BU9847GUL-W Capacity 4Kbit Bit format 512×8 Type BU9847GUL-W Power source voltage 1.7~5.5V VCSP50L1 ● ●Absolute maximum ratings (Ta=25°C) Parameter Impressed voltage Permissible dissipation Storage temperature range Operating temperature range Terminal voltage * Symbol Vcc Pd Tstg Topr - Ratings -0.3~+6.5 220 *1 Unit V mW ℃ ℃ V -65~125 -40~85 -0.3~Vcc+1.0 When using at Ta=25℃ or higher, 2.2mW (*1) to be reduced per 1℃ ●Recommended action conditions Parameter Power source Input voltage voltage Symbol Vcc Vin Ratings 1.7~5.5 0~Vcc Unit V ●Memory cell characteristics (Ta=25°C, Vcc=1.7~5.5V) Parameter Number of data rewrite times *1 Data hold years *1 Not 100% TESTED Limits Min 1,000,000 40 Typ.
