BU9833GUL-W

High Reliability Series Serial EEPROMs WL-CSP EEPROM family I2C BUS BU9833GUL-W No.10001EAT17 ●Description 2 BU9833GUL-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 Write (write protect) function added. Write mistake prevention function at low voltage. 9) Data rewrite up to 1,000,000times. 10) Data kept for 40 years. 11) Noise filter built in SCL / SDA terminal 12) Shipment data all address FFh. ●Page write Product number BU9833GUL-W ●BU9833GUL-W Type BU9833GUL-W ●Absolute maximum ratings (Ta=25℃) Parameter Impressed voltage Permissible dissipation Storage temperature range Operating temperature range Terminal voltage Symbol Vcc Pd Tstg Topr – Ratings -0.3~+6.5*1 220 -65~125 -40~85 -0.3~Vcc+1.0 Unit V mW ℃ ℃ V Capacity 2Kbit Bit format 256×8 Power source voltage 1.7~5.5V Package VCSP50L1 Number of pages 16Byte ・When using at Ta=25℃ or higher, 2.2mW (*1) to be reduced per 1℃ www.rohm.com © 2010 ROHM Co., Ltd.
