| 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.
