Hello, I'm looking to monitor 7 voltages: 0.85V, 0.95V, 0.9V - 1.1V, 1.5V, 1.8V, 2.5V and 3.3V. I was looking at the PSoc5 devices and was wondering if this would be a good choice to monitor these voltages. Can anyone comment on this or suggest a better device? I was also looking at Altera's MAX10 device but I would rather use a microcontroller.
Thanks,
Joe

This is of course a question of
Frequency - How often need the values be sampled/s
Precision - How many bits are needed
and last: What do you want to do with the 7 values?

Bob,
Hello, how about measure every second with a resolution of millivolts and send the values to a LCD display over SPI.

Bob,
Thank you very much for the suggestion. Is the PSoc6 a better choice than the PSoc5 on this topic of voltage monitoring?
Thanks,
Joe

The PSoC6 is a bit more complicated because it contains two MPUs which can be programmed individually. For your requirements a PSoC5 will be sufficient. Even a PSoC 4 would be enough to handle your requirements.

Bob,
Hi, one more question for you. I'm looking at the datasheet for the PSoc 5LP family of microcontrollers and on page 4 they have 4 opamps in the Analog System block. My question is, can the Analog System sample any of the GPIO pins? Or only the pins that have OPAMPxp/n, so that means I can only monitor 4 signals.
Thanks,
Joe
