I currently own a CY8CKIT-059 Psoc 5LP Prototyping kit. I was wondering how accurate the internal timing mechanism aka the on board clock. Also, if there are any recommendation on any crystal oscillator I should look into buying to improve the accuracy of the clock.
For PSoC 5LP, the internal IMO and PLL together can generate up to a 80-MHz clock, accurate to ±2% over voltage and temperature.
You can choose external oscillators to improve clock accuracy, It supports a wide variety of crystal types, in the range of 4 to 25 MHz.
For more details about PSoC 5LP, you can refer to resources shared in PSoC 5LP forum:
