SRAM space: 128 bytes.
¨ level 8 deep hardware stack
¨ I / O pin configuration
14 I / O pins with direction control: 5 Pa ports and 8 PC ports.
When PA3 is output, it can only open drain output.
High perfusion current can directly drive LED (except PA3).
PA port pin level change interrupt.
Programmable weak pull-up / pull-down of PA and PC ports (except PA3). ¨ timer
Timer0: 8-bit timer / counter with 8-bit programmable prescaler.
Timer1 / 2: 16bit timer / counter
-16 bit timer / counter with prescaler.
-External Timer1 / 2 gating (count enable).
-If intosc mode is selected, or it can be used in LP mode
Osc1 and osc2 act as Timer1 / 2 oscillators.
¨ 4-channel 12 bit resolution PWM module
4 channels of 12bit high-resolution PWM output.
¨ 13 + 1 channel 12 bit ADC
13 external ADC inputs.
Internal 1 / 4VDD channel input.
Various ADC startup modes.
ADC reference voltage can be selected as internal or external reference by software.
When the internal reference is selected, the on-chip 1.024v can be selected through the configuration register,
2.048v, 4.096V or VDD as the reference voltage.
¨ dual clock system
External high-speed clock: up to 20MHz.
Internal high speed clock: 16mhz RC
Fcpu only supports (16mhz, 8MHz, 4MHz, 2MHz, 1MHz, 500khz250khz).
Internal low-speed clock: RC oscillator 31khz.
¨ high performance RISC CPU
Only 35 instructions need to be learned.
All instructions except jump instructions are single cycle.
Direct, indirect and relative addressing modes.
¨ special features
-High precision internal oscillator with factory calibration accuracy of + / - 1%.
Deviation less than + / - 2%
-The frequency range that can be selected by software is 250kHz to 16mhz- Software optional 31khz internal oscillator.
-Energy saving sleep mode.
-Wide operating voltage range (2.2V to 5.5V).
-Industrial grade temperature range (- - 40 ℃ ≤ TA ≤ + 85 ℃)- Power on reset (POR).
-Power up timer (PWRT) and oscillator start
Oscillator start uptimer (OST).
-LVR low voltage detection selection with software control selection (detection voltage
2.0V, 2.5V, 3.0V, 4.0V (optional).
-On chip oscillator (the oscillator frequency can be selected by software when the pre division ratio
When large, its nominal value is 268 seconds) and can be software enabled enhanced low current
Watchdog timer (WDT).
-The multiplexed input is the main band reset pin- Programmable code protection.
