IC



This is IC that detects variation of analog data, and then it is converted to the digital signal. It senses analog data every 3 msec, and convert to 10 bit digital data. By an original circuitry, we realized super low power consumption.



Main Characteristic

» operation voltage
      2.5V - 5.5V

» Interface Voltage
      1.4V - 5.5V

» power consumption (sampling : 3msec)
      active
            43.0uA(typ)@2.5V,  54.0uA(typ)@3.3V
      wait
            4.5uA(typ)@2.5V,  9.0uA(typ)@3.3V
      sleep
            0uA(MAX)@2.5V,  100uA(MAX)@3.3V

» Interface
      I2C

» speed
      ->400kHz

» polling style
      IC is updating the data every 3msec with 10 bit AD when active mode.HOST MCU needs to make the data polling speed faster than 3 msec. READ data length is 7 bytes.

» SLEEP and WALE UP mode
      It is getting into the idle mode after receiving the command from HOST.By touching the VectorPad when Idle mode, because of WAKE UP port status changes, it moves to the active mode by receiving command from HOST.

» how to reset
      IC has RESET port, it is able to make reset by initializing the internal resister .

» internal clock
      IC has an internal clock oscillator.

» peripheral parts
      Two pull up resistors for I2C, and one 0.1uF bypass capacitor

» Size, Outer dimension
      4.00 x 4.00 x 0.85mm
