  • Forum Post: Re: CDCE906 SMBus compatibility with I2C

    mapefer3
    The CDCE906 and CDCE706 are both SMBbus communication type of devices. When using a uController that generates I2C protocol it might be that the timing between the SCK falling edge and the change of SDA is not respected for SMBbus but it is respected for I2C. Special care must be taken on the SDATA...

  • Forum Post: CDCE913 Not Responding to I2C Command Interface

    bfsystems
    I am pulling my hair out trying to get a PIC MCU (18F46J50) to communicate with a CDCE913. The I2C bus transfers appear to be working (looking at a scope), but the TI device isn't responding functionally as it should. It appears to be stuck in the default power-up configuration, which is passing...

    Sorry - I just read the datsheets and app notes for what feels like the gazillionth time. I must be blind or something. I was not setting bit 7 of the command words to properly indicate byte read/write versus block read/write operations. Duhh - - - its the simple and obvious that's most difficult...

  • Forum Post: BQ32000 clock source

    Yogesh Palkar
    Hi, I have used BQ32000 in a circuit. I have used a 32.768kHz crystal as suggested. Is there any need to connect capacitors to the crystal? Or will the crystal simply work alone? Currently I have connected the crystal alone and the Oscillator flag bit is set to 1. If needed, what value of crystal...

    Hello Ryan Kehr sir, The crystal that is suggested is not available locally. So I have used a 32.768kHz crystal that is available locally. In general for these crystals we use a ceramic low value capacitor. As in for a microcontroller, we connect a 33pF capacitor. Now is capacitor connection necessary...
