One-Board Discovery Kit with Three, 8-Pin Microcontrollers

For under $10, the STM8-SO8-DISCO 8-bit microcontroller (MCU) Discovery Kit from STMicroelectronics lets users evaluate all three STM8 variants currently available in the popular 8-pin SO8 package.

As well as an outstanding three-in-one value, the kit offers no-frills simplicity and features to jump-start the next stage of development. A single button and indicator LED are incorporated for interacting with the board, and the embedded STLINK/V2 and USB port simplify in-circuit debugging and programming from a connected PC. Debugging of an external target is also possible with a SWIM connector.

The MCUs are soldered onto individual break-offs that can be separated from the compact main board as pluggable DIL-8 modules ready to start prototyping. The supported MCUs are the STM8S001J3M3, STM8L001J3M3, and STM8L050J3M3.

The STM8S001J3M3 delivers affordable performance with features such as advanced 16-bit timers with three comparator outputs, three capture-compare channels, a 10-bit ADC, and an 8-bit timer. The ultra-low-power STM8L001J3M3 consumes just 0.3µA in halt mode and integrates 8- and 16-bit timers and two comparators. Also employing ultra-low-power technology, the STM8L050J3M3 adds a 12-bit ADC and 4-channel DMA controller.

The MCUs all have the company’s STM8 core running at 16MHz, and 8Kbyte on-chip Flash. System-control features include watchdog and clock control, and popular communication interfaces such as UART, SPI, and Fast I2C. With up to six user I/Os, they are perfect for use in industrial sensors, home-automation, smart lighting, access cards, battery chargers, or smart printer cartridges.
