• Operating Voltage

• 2.1V~5.5V at 0°C~70°C (commercial)

• 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

• IRC mode: 

          Oscillation mode: 16MHz, 4MHz, 1MHz, 455kHzn.

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

• Programmable free running Watchdog Timer(4.5 ms : 18 ms)
• Power saving Sleep mode
• Selectable Oscillation mode
• Power-on voltage detector available (1.7V ± 0.1V)
