4 Clock Source:
- 16MHz high speed internal oscillator with ±1% accuracy at 5.0V power supply. All operating conditions range ±2% accuracy class.
- 10 kHz low speed internal oscillator.
5 Functions:
- Up to 18 standard universal pins.
- Standard external interrupt pins INT0 and INT1.
- Two sets of 16-bit timers/counters 0 and 1, compatible with standard 8051.
- A set of 16-bit timers 2 with 3-way input capture and 9 input pins to choose from.
- A set of 16-bit automatic reload function timers 3.
- A set of 16-bit PWM counting interrupts.
A set of watchdog (WDT) with an internal 10 kHz independent clock as the clock source.
- A set of self-wake function timers (WKT) for self-wake in low power mode.
- A set of full-duplex serial ports. The TXD and RXD pins can be replaced by software.
- A set of SPI buses, when the system clock is 16MHz, the maximum transfer rate can reach 8Mbps in both host mode and slave mode.
- A set of I2C buses with a maximum transmission rate of 400kbps in both host mode and slave mode.
- Three pairs, 6-channel pulse width modulator (PWM), 10 output pins to choose from, 16-bit resolution, with different operating modes and FaultBrake function.
- Up to 8 channel pin interrupts can be configured. All I/O ports support this function. Edge or level triggering can be configured by software.
- A set of 12-bit ADCs with a sampling rate of up to 380ksps, allowing easy control of motor functions with hardware startup and comparison of conversion results.
6 Power Management Module:
- Two power saving modes: idle mode and power off mode.
7 Power monitoring:
- Undervoltage detection (BOD) Detects the low power supply voltage of the system. The four-level voltage can be selected and interrupts can be configured
- Power-on Reset (POR)
8 Strong ESD and EFT capability
