STM8S Slide 11

All STM8S devices operate from a single voltage supply between 2.95V to 5.5V with products available for temperature operation from -40°C to 125°C. This block diagram shows the up to 20 MIP 24 MHz STM8 core, interrupt controller and clock controller with clock security system. The system and supervisory functions include the reset block, internal regulator and internal high speed and low speed RC oscillators. The 16 MHz internal RC oscillator can be trimmed to +/-1%. The boot ROM allows firmware updates through UART, CAN, or LIN. Serial interfaces include at least one UART, SPI, and I2C on all STM8S devices with a second UART and CAN available on the Performance Line. Peripherals include an advanced 16-bit timer, second 16-bit timer, 8-bit timer, two watchdogs (one running from an independent clock) and AWU (auto wake-up unit) on all STM8S devices with an additional 16-bit timer on some devices. All devices have a 16-bit ADC and 5 V tolerant GPIOs. The Single Wire Interface Module allows fast programming of less than 6 seconds for 128 KB.
