I don't see a max voltage range for VDDIO in the data sheet. And in Creator, cydwr shows that pin at 3.3V for some reason. Makes me wonder if VDDIO can run up to 5V (which is what I want). And of course this should be in the data sheet... or did I miss it? I looked through the Absolute Maximum Ratings section.
Solved! Go to Solution.

Hi,
I also could not find specific max range of VDDIO in the data sheet,
but I found the line below in the PSoC 4 Hardware Design Considerations AN88619
VDDIO ≤ VDDD ≤ VDDA
And in the PSoC 4: PSoC 4200L Datasheet I found the following, in the Table 1. Absolute Maximum Ratings
So I hope that we can assume
VDDIO ≤ VDD+0.5
So I tested by creating a simple project targeting device PSoC 4200L
DWR > System
I enter 5.0 for all VDDA, VDDD, VDDIO
Schematic
main.c
==========
#include "project.h"
int main(void)
{
CyGlobalIntEnable; /* Enable global interrupts. */
/* Place your initialization/startup code here (e.g. MyInst_Start()) */
for(;;)
{
Pin_2_Write(Pin_1_Read()) ;
}
}
==========
And the project could be compiled
