Could someone please explain the differences between the IRC oscillator and the system oscillator from a circuit point of view as well as stability over temperature and supply?

Is the IRC oscillator a Resonant Crystal osc. on chip or is it a more typical R-C (resistor-capacitor) oscillator?
What is the system oscillator made of? I could not find any info.

Since the time base is very important in our application, we need to understand these differences (and we can't really afford a crystal on the BOM).

Thank you!
