Presentation Notes
Several innovations are coming with the STM32G0 Series to allow customer select the most compact microcontroller package with a minimum set of external components, thus reducing significantly the BOM cost: - Only 1 power supply pair up to 64-pin packages provide more IOs - The embedded 1% accurate clock across a wide temperature range from 0°C to 90°C allows to remove external components - Bigger flash and RAM fit into packages as small as 28-pin up to 128 Kbytes Flash, or 32-pin up to 512 Kbytes Flash Can you guess the savings associated? Let’s go to the next slide.
Innovations for Your Benefit 4
• No external clock -10ctsAccurate internal high speed clock +/-1% for 0 / 90°C
• No decoupling capacitances -4ctsRemove up to 6 decoupling capacitors for supply and clocks
• Smaller PCB -1ctsSmaller package, less components: save on PCB area
Additional benefits for your convenience:
• USB-C power delivery -15ctsIntegrated transceivers, pull-up/down resistors and digital
• Secure programming -25ctsIn house or at 3rd parties

Presentation Notes
When computing the savings on the bill of material, the savings are significant for the benefit of STM32G0 users: - the internal high speed clock supports +/-1 % accuracy from 0 to 90°C, and less than +/-2% from -40°C to +125°C. Practically, most applications will be able to operate without external clock, thus removing the clock itself, but also decoupling capacitances. - One power supply up to 64-pin package also allows to remove more decoupling capacitances. - One power supply up to 64-pin package means also smaller package, better cost, and savings on board material. All together, one can easily consider 15 cents savings when buying STM32G0 compared to a standard solution. And guess what: more can be saved, thanks to the integrated USB type C power delivery, or secure programming capabilities and services.

What about current consumption? Be prepare for a very nice surprise: the STM32G0 Series bridges the need for efficient and compact MCU with the most demanding efficiency on current consumption, usually served with dedicated microcontrollers. When it comes to extending battery life or meeting new eco-friendly standards, STM32G0 is a microcontroller of choice. Let us list some typical consumptions: - Excellent dynamic consumption below the 100 µA/MHz - Stop mode from 3 to 8 µA with or without Real Time Clock - Stand-by mode at 500 nA with RTC or even down to 200 nA without Real Time Clock - Shutdown mode allows to reach as low as 40 nA if wake-up time if no major constraint - VBAT mode allows to decrease down to few Nano amperes, up to 400 nA with Real-Time Clock

Presentation Notes
How to get cost advantage with a microcontroller? Because it embeds so much in it. Those are the system integrated features: - A full set of monitoring functions allow to always keep control, diagnose and react whatever happens on the CPU, flash, clock or voltage. There is always a fallback plan and the microcontroller is never stuck. - Robust in temperature, the STM32G0 can operate up to 125 °C ambient temperature. - Robust against disturbances, the STM32G0 is particularly immune against fast transient voltages, reaching the level and class 5 A, which means practically more than 8 kV on the equipment. - Whatever is customer’s topology, the STM32G0 demonstrates high flexibility with a dynamic DMA mapping, all IOs with external interrupt capability and extra RAM capability by disabling parity. - Last but not least, let us remind the BOM cost and battery life savings addressed in the previous slides.

Let’s take a look at the portfolio coverage: what do we see? The STM32G0 Series is available from 8-pin SO package, delivering up to 6 IOs! But the same series also extends up to 512 Kbytes and 100-pin packages, allowing a platform approach while remaining on the same Series. Look at this interesting area: Big flash on small packages: it combines the need for more flash or RAM with the lowest possible impact on BOM or PCB area. Here again, the efficiency of the STM32G0 Series is at its best. Several package flavors are available to answer different needs such as easy handling, low-thickness, smallest area impact, or different pitch requirements. There is always a corresponding STM32G0!

The Evaluation board enables a deep dive into the STM32G0 features. The STM32G0 Series is supported by the STM32CubeMX configuration tool and the STM32CubeG0 package. STM32CubeMX offers an intuitive and graphical configuration for pinout, peripherals, clock setting, and for power consumption simulation. It will create the framework to start developing your application so quickly. Then re-use easily an existing code or develop your new program with the Hardware Abstraction Layer library. This is the good way for maximum re-use and easy porting. Also available, the Low-Layer drivers get closer to the register implementation for optimized footprint.

Presenter
Presentation Notes
The STM32CubeMX relies on the STM32Cube embedded software bricks to generate the peripheral initialization code. The first firmware layer of these embedded software bricks is made up of the low-level drivers, i.e the Hardware Abstraction Layer (HAL) and the low-layer (LL) APIs. The HAL implements a high portability between STM32 series, while the LL APIs bring the performance aspect to the STM32CubeG0 offer. The HAL abstracts the STM32 series from one another, thanks to a highly portable set of APIs, thus ensuring an easy migration path from one series to another. The LL APIs are a lot closer to the machine and constitute a light-weight, high-performance, expert-oriented firmware stack for maximum dynamic reactivity and flexibility. Last but not the least, these low-level drivers are distributed under the BSD license, one of the most permissive and business-friendly open-source licenses. For more convenience, the STM32CubeG0 embedded firmware also comes with a set of middleware bricks. They are portable on any STM32 series that supports the required functionality. These middleware bricks also come for free, and most of them are based either on open-source de facto standards, or ST deliverables with permissive and business-friendly license terms. In addition, numerous examples are provided to help the customer understand how to use the HAL, the LL APIs, and the middleware with the microcontroller. ST proposes high-quality low-level drivers which have been thoroughly qualified using both standard and ST-specific validation tools and processes. For more information, you can refer to the presentation dedicated to the STM32Cube embedded software qualification.
