Question

C8051 and EFM8 devices include a high-precision 24.5 MHz internal oscillator, with a minimum / maximum frequency specification of 24 MHz / 25 MHz (2% accuracy). Is this specification guaranteed over the life of the device?

Answer

Yes. This specification is guaranteed to be held across the entire life of the device.

 

These devices have been characterized with a 1000-hour high-temperature operational life (HTOL) to determine how the devices will change over their lifetime. For the precision internal oscillator, no significant change was observed.
