    Question:

    What are the power modes in which the Programmable Analog Blocks – Universal Analog Block (UAB), Continuous Time Block (CTB), SAR ADC, and Programmable Reference Block (PRB) can be operated?

     

    Answer:

    PSoC Analog Coprocessor have three power modes – Active, Sleep and Deep-Sleep. The following table lists the modes in which the Programmable Analog Blocks can operate:

                                                                              

    Programmable Analog BlockPower Modes
    UABActive, Sleep
    CTBActive, Sleep, Deep-Sleep*
    SAR ADCActive, Sleep
    PRBActive, Sleep

     

    * Limitations:

     

    1. 10x driver is available but 1x driver is disabled
    2. Input to the opamp is limited to (VDDA –1.5 V)
    3. For VDDA > 2.7 V, CTB is functional across the device operating temperature range specification with opamp high, medium, and low power modes. For 2.4 V < VDDA < 2.7 V, CTB functionality is limited to 0 to 85 °C temperature range with only low-power mode. 

     

    For more information on the architecture of CTB and CTBm, see the technical reference manuals.
