Advanced STM8 core
Clock, reset and power management: 3.0~5.5V working voltage, flexible clock control, low power mode, always open low power and power down reset.
Communication Interface: with synchronous clock output UART, smart card, infrared IrDA, LIN interface.
Development support: Single line interface module (SWIM) and the debug module (DM) can facilitate online programming and non intrusive debugging.
Structure: Extended Instruction Set; Memory: Medium Density Program and Data Memory: Up to 32K bytes of Flash; data can be stored for 20 years at 55℃ after 10K erasing and rewriting

Power Management:
Low power modes (waiting, active shutdown, shutdown)
Peripheral clocks can be individually turned off, always-on low-power power-on and power-down resets
Interrupt management: Nested interrupt controller with 32 interrupts, 6 external interrupt vectors, up to 37 external interrupts
Timers: 2 16-bit universal purpose timers with 2+3 CAPCOM channels (IC, OC or PWM), Advanced Control Timer: 16-bit, 4 CAPCOM channels, 3 complementary outputs, dead-time insertion and flexible Synchronization, 8-bit base timer with 8-bit prescaler, auto wake-up timer, 2 watchdog timers: windowed watchdog and independent watchdog
Communication interface: UART with synchronous clock output, smart card, infrared IrDA, LIN interface
SPI interface up to 8Mbit/s, I 2 C interface up to 400Kbit/s analog-to-digital converter analog-to-digital converter (ADC), 10-bit, +/- 1LSB ADC, up to 10 channels, scan mode and analog watchdog Function
I/O Ports: Up to 38 I/Os on a 48-pin package, including 16 high sink current outputs, very robust I/O design, very strong ability to withstand backflow current
Development Support: Single Wire Interface Module (SWIM) and Debug Module (DM) for easy in-circuit programming and non-intrusive debuggi
