Minimum Supply Voltage to PSoC 1

Version 1
    Question: What is the minimum operating supply voltage that can be provided to PSoC1 devices ?

     

    Answer:

    The following part families can work on a minimum supply voltage of 2.4 V:

    •   CY8C24x23A
    •   CY8C22x13A
    •   CY8C21x23
    •   CY8C21x34
    •   CY8C20x34

    The following part families can work on a minimum supply voltage of 3 V:

    •   CY8C24x94
    •   CY8C29X66
    •   CY8C27X43
    •   CY8C22x45
    •   CY8C28xxx

    CY8C20xx6A can work on a minimum supply voltage of 1.71 V.

    Note: CY8C21x34 devices need a minimum voltage of 2.5V during POR.
