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?


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.
