You can find ADC that also include temperature sensors. I know ADI
makes a few. But I have found that external ADCs tend to be a bit
expensive compared to the MCU, especially when they contain a
temperature sensor. I suggest that you go with an MCU that has an
internal temp sensor and ADC. The ADuCxxxx family of parts are
specifically designed to have good ADC at a reasonable price. The low
end devices are 8051 powered and the higher end devices contain an ARM7
core.

Hello,
In my next uC design I need to check periodically battery and uC
temperature and battery and power-supply voltage.
I do not have a native I2C nor 1Wire on the uC wherever CAN or SPI or
some IOs are available.
What I prefer would be a kind of simple 2wire interface to some small
and handy sensors.
Some recommendations ? Are there some don't use sensors?
Thx,
theAdib.
