PSoC 4 MCU

Contributor

Hi,

  • Is it possible to run power mode 1 (powering the psoc with a 4-5V supply), and get the IO voltages to be 1.8V
  • How much current can VCCD provide (assuming we use this 1.8V tap to power some low-current peripheral IC's)

From the datasheet below:

Mode 1: 1.8 V to 5.5 V External Supply

In this mode, the PSoC 4000S is powered by an external power supply that can be anywhere in the range of 1.8 to 5.5 V.

Hi,

The IO voltage is derived from VDDD.

No, this is not supported.

how about the io voltage, will that be 1.8V or 1:1 with the supplied rail, ie 3.6-4.2v running off a lipo battery!?
