- Operating Frequency range (base on 2 clocks)
- Crystal mode:
DC~16MHz, 4.5V;
DC~8MHz, 3V; DC ~ 4MHz, 2.1V
- ERC mode:
DC ~ 16MHz, 4.5V;
DC ~ 8MHz, 3V;
DC ~ 250ns inst. Cycle, 3V
Oscillation mode: 16MHz, 4MHz, 1MHz, 455kHzn.
- IRC mode:
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.
- Fast set-up time requires only 0.8ms (VDD: 5V Crystal: 4MHz, C1/C2: 30pF) in HXT2 mode and 10ms in IRC mode (VDD: 5V, IRC: 4MHz)
- Peripheral configuration
- Easily implemented IR (infrared remote control)
- 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
- 8-bit real time clock/counter (TCCA, TCCC) and 16-bit real time clock/counter (TCCB) with selective signal sources, trigger edges, and overflow interrupt
- 7-bit multi-channel Analog-to-Digital Converter with 12-bit resolution in Vref mode
- Five available interrupts
- TCC, TCCA, TCCB, TCCC overflow interrupt.
- Input-port status changed interrupt (wake up from sleep mode)
- ADC completion interrupt
- IR/PWM period match completion
- Low voltage detect (LVD) interrupt
- Special features
