Compared with STM8S003F3P6

STM8S003F3P6: A total of 20 pins, support up to 16 GPIOs, support 16 external interrupts; 2 16-bit timers [TIM1/TIM2], can output up to 3 PWM signals; 5 ADC channels, support SPI/I2C/UART 8KBYTE FLASH, 1K RAM, 128 BYTE EEPROM; built-in 16M high speed oscillator, WDG and more.

From the performance of the single slave device: Xintang's N76E003AT20 has a classic advantage compared to:

• 1T/8051: 1T value-for-money microcontroller, 8051 classic kernel we are more familiar with;

• 18KB Flash ROM: better than 8KB Flash, and 18KB of flash space, all of which can be used as data storage space applications;

• 1024B SRAM;

• 17+1 input ports: better than up to 16 GPIOs;

• 2*UART, I2C, SPI: better than SPI/I2C/UART (more than one UART);

• 8ch of 12bit ADC: better than a 5-channel 10bit ADC;

• 6ch of individual duty PWM: better than 3 PWM outputs;

• 10KHz LIRC for WDT reset / WKT ;

• 16MHz HIRC ±1% Room temp. ±2% full condition;

• -40~105 °C temperature range is wider;

• 2.4V to 5.5V wider supply voltage range;

• TSSOP20 / QFN20;

• ESD&EFT: HBM/8KV MM/400V, Over 4KV, excellent ESD and EFT, immunity to interference and ESD protection;
