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, interface. Development support: Single line interface module (SWIM) and the debug module () 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 : 2 16-bit universal purpose with 2+3 channels (IC, OC or PWM), Advanced Control : 16-bit, 4 channels, 3 complementary outputs, dead-time insertion and flexible Synchronization, 8-bit base with 8-bit prescaler, auto , 2 watchdog : windowed watchdog and watchdog Communication interface: UART with synchronous clock output, smart card, infrared IrDA, 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 () for easy in-circuit programming and non-intrusive debugging colour: black Material: ABS+metal Size: 49.3x23.1mm Package Contents: 2 x STM8S Development Board Only the above package content, other products are not included.
