TABLE 32-19: INTERNAL FRC ACCURACY
AC CHARACTERISTICS
Standard Operating Conditions: 3.0V to 3.6V (unless otherwise stated)
Operating temperature -40°C ≤ TA ≤ +85°C for Industrial
-40°C ≤ T
A ≤ +125°C for Extended
Param. Characteristic Min. Typ. Max. Units Conditions
Internal FRC Accuracy @ FRC Frequency = 7.37 MHz
(1)
F20a FRC -2 — +2 % -40°C ≤ TA ≤ +85°C VDD = 3.0-3.6V
F20b FRC -5 — +5 % -40°C ≤ T
A ≤ +125°C VDD = 3.0-3.6V
Note 1: Frequency calibrated at 25°C and 3.3V. TUN bits can be used to compensate for temperature drift.
