www.st.com/mcuwww.st.com/mcu February 2010 STM8S/STM8A/STM8L 8-bit microcontroller families 2 STM8 stands for a platform of technologies, IPs and tools which form the basis of STMicroelectronics’ comprehensive family of 8-bit microcontrollers. These cover a wide range of applications from low-power and consumer electronics through home appliances and factory automation to automotive. The platform provides outstanding levels of digital and analog performance combined with a high level of cost- effectiveness. Implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals, the microcontrollers in the STM8 family are manufactured using an ST-proprietary 130 nm embedded non-volatile memory technology. STM8 core The STM8 core is an evolution of the industry-standard ST7 core. It has been significantly improved to reach 1.6 cycles per instruction and up to 24 MHz clock frequency.

These technologies are highly competitive due to the outstanding integration level. As a result, all STM8 devices feature real data EEPROM with read while write capability. This means an easy-to-use data NVM eliminating the need for complex EEPROM emulation software. The performance of the integrated EEPROM is at the same level as standalone devices, meeting even the most demanding automotive reliability standards. Low-power technology The ultra-low-power design (clock gating, low-power Flash with power- off capability) ensures reduced overall run and wait mode current consumption by turning off clocks of unused peripherals or Flash. Multiple modular-technology options allow solutions for high-speed, ultra-low leakage and power, high integration level or analog performance. Rich portfolio Up to 128 Kbytes of program memory, up to 80-pin packages, and 145 °C max. operating temperature make the STM8 a perfect fit for strategic platform choices, and facilitates reuse of design concepts. Large voltage range With a voltage range from 1.65 to 5.5 V, the STM8 families can cover a wide scope of application segments. Family concept The compatibility within and across the families through a modular peripheral set simplifies design reuse, so improving time to market. The hardware implementation in the STM8 devices provides a consistent migration across the package families. Increasing or decreasing the pin count with a similar location for supply, control or peripheral pins simplifies the hardware design and validation. Analog Inputs System Timers Communications Moreover, the flexible alternate function mapping ensures all communication peripherals (U(S)ART, I²C or SPI) are always available and brings the versatility of low pin count packages to a new level. 33 Robustness The products are designed to withstand a high level of external disturbance, ensuring robust applications without the expense of external protection elements. Immune against EMS and robust against latch-up or ESD, with built- in checksum mechanisms, the products support IEC 60335 class B compliance. The main contributors to this robustness are the clock controller with 2 independent watchdogs and the clock security system (CSS), as well as a protection mechanism for critical registers and illegal opcodes. Mux 1 to 24 MHz Xtal and external clock 128 kHz internal RC oscillator Window watchdog 16 MHz internal RC oscillator CSS WDG timer Clock control unit CPU and peripherals The I/Os of the devices feature a high level of robustness against current injection when the protection diodes are used for clamping. During reset of the microcontroller, the I/Os are in high-impedance state. I/O - 4 mA injected current I/O < 1 µA leakage on adjacent pins Debug module and SWIM interface SWIM A single-wire interface module allows direct access to the debug module, the registers and the device memory. The interface can be activated in all device operation modes and supports debugging and programming of the device. Debug module The non-intrusive debug module is present on each STM8 device. It is conncected to the internal bus and allows breakpoint setting and CPU monitoring and control. In-circuit debugging Application debugging on microcontroller products has never been easier or more affordable. Using the advanced single-wire SWIM interface and the integrated debug module, a simple USB adapter turns your PC into a powerful development tool featuring: Non-intrusive debugging – no wasted target resources, no reserved NVM QQ addresses, no monitor Real-time read and write of RAM and peripheral registers – no wait, no stallQQ On-the-fly access to CPU via shadow registersQQ Hot-plug during application execution and post-mortem debugQQ Unlimited breakpoints on all memory instructionsQQ Hardware breakpoints – 23 configurationsQQ Step-by-step code executionQQ Fast Flash programmingQQ For the most demanding applications, ST offers the FPGA based STice emulator, which complements the environment with solutions for code tracing, code coverage measurement and profiling.
