Internal RC Frequency Drift Rate
Temperature(-40°C~85°C) Voltage(2.3V~5.5V) Process Total
4 MHz ±5% ±5% ±4% ±14%
16 MHz ±5% ±5% ±4% ±14%
1 MHz ±5% ±5% ±4% ±14%
455 kHz ±5% ±5% ±4% ±14%

All the four main frequencies can be trimmed by programming with four calibrated bits in the ICE341N Simulator. OTP is auto trimmed by ELAN Writer.
