Note 1: Assumption: Oscillator Postscaler is divided by 1.
2: Instruction Execution Cycle Time: T
CY = 1/MIPs.
3: Instruction Execution Frequency: MIPs = (FOSC * PLLx)/4 (since there are 4 Q clocks per instruction cycle).

OS63 Internal FRC Accuracy @ FRC Freq. = 7.37 MHz
(1)
FRC — — ±2.00 % -40°C ≤ TA ≤ +85°C VDD = 3.0-5.5V
— — ±5.00 % -40°C ≤ T
A ≤ +125°C VDD = 3.0-5.5V
Note 1: Frequency calibrated at 7.372 MHz ±2%, 25°C and 5V. TUN <3:0> bits can be used to compensate for
temperature drift.
