Minimum Supply Voltage to PSoC 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.
