BU9889GUL-W Datasheet | ROHM

Description 2 BU9889GUL-W is a serial EEPROM of I C BUS interface method. - Features 2 1) pletely conforming to the world standard I C BUS. All controls available by 2 ports of serial clock (SCL) and serial data (SDA) 2) 1k words×8 bits architecture 8kbit serial EEPROM. 3) Other devices than EEPROM can be connected to the same port, saving microcontroller port. 4) 1.7～5.5V single power source action most suitable for battery use. 5) FAST MODE 400k Hz at 1.7～5.5V 6) Page write mode useful for initial value write at factory shipment. 7) Auto erase and auto end function at data rewrite. 8) Low current consumption At write operation (5V) : 0.5m A (Typ.) At read operation (5V) : 0.2m A (Typ.) At standby operation (5V) : 0.1µA (Typ.) 9) Write mistake prevention function Write (write protect) function added Write mistake prevention function at low voltage 10) WLCSP6pin pact package 11) Data rewrite up to 100,000 times 12) Data kept for 40 years 13) Noise filter built in SCL / SDA terminal 14) Shipment data all address FFh - Absolute maximum ratings (Ta=25℃) Parameter symbol Impressed voltage Permissible dissipation Storage temperature range Action temperature range Terminal voltage VCC Pd Tstg Topr No.10001EAT07 Limits -0.3+6.5 220- 1 -65+125 -40+85 -0.3～Vcc+1.0 Unit V m W ℃ ℃ V - 1 When using at Ta=25℃ or higher, 2.2m W to be reduced per 1℃ - Memory cell characteristics (Ta=25℃, Vcc=1.7～5.5V) Limits Parameter Min.
