 Hello and welcome to this introduction to the STM32C0 microcontroller series. This short presentation describes the various lines available in the new STM32C0 series of entry-level microcontrollers for cost-sensitive applications. The STM32C0 microcontrollers have been designed with the following objectives affordability, very low cost, reliability, benefits from proven STM32 quality and reliability, continuity, consistent pinout with STM32C0 that simplifies the design of board and software targeting of the two MCU families. This slide summarizes the portfolio of MCU's and MPU's designed by ST Microelectronics. It's divided into five categories, MPU, high performance MCU's, mainstream MCU's, ultra low power MCU's and wireless MCU's. The STM32C0 belongs to the mainstream MCU product line. This is an entry-level microcontroller that can run up to 48 MHz. Performance expressed in CoreMark is 114, which is slightly above the one of the STM32F0 series. The STM32C0 is based on an ARM Cortex M0 plus core, which is a 32-bit processor supporting a 4GB flat-address space. In terms of software design, this is much easier to manage than paging required by 8-bit and 16-bit processors. Thus, the STM32C0, due to its performance and low consumption, can efficiently replace 8-bit and 16-bit MCU's. Here's the list of typical applications for which the STM32C0 can be appropriate. Smart home, appliances such as fridges, ovens, coffee machines, industrial, alarm detectors, pumps, circuit breakers, and consumer devices, PC peripherals and accessories, e-cigarettes. The STM32C0 is the most cost-effective STM32MCU. It also contributes to reduce the bomb cost because it requires fewer surrounding components. Only one external power supply is necessary. Clocks can be synthesized from an internal oscillator, which is 1% accurate and very stable over temperature. If a more accurate clock is needed, an external crystal can be used as well. ST offers these devices in 9 packages, starting with 8-pin SO8N. Several innovations are coming from the STM32C0 series to allow customers to elect the most impact microcontroller package with a minimum set of external components, thus reducing significantly the bomb cost. Only one power supply pair provide more IOs. The embedded 1% accurate clock across a wide temperature range from 0 to 90 degrees Celsius allows to remove external components. 32 or 16 kilobyte flash and 12 or 6 kilobyte ram fit into packages from 8-pin to 48-pin. The STM32C0 supports a wide set of packages types fitting different sizes and width requirements such as WLCSP, TSSOP, SON, LQFP and UFQFPN packages. The STM32C0 shares the same technological platform as the STM32G0. Both are based on ARM Cortex M0 Plus Core running up to 48 MHz. They deliver 44D MIPS instruction throughput with 114 core mark performance. Continuity with STM32G0 family includes consistent pinout, same IP platform enabling software reuse, same 90 nanometer technology platform. Ten-year longevity commitment program ensures continuous supply for 10 years. The pinout of STM32C011 is consistent with STM32G031 as shown in the two figures describing the 8-pin SO8N and 20-pin TSSOP packages. Due to the unique FDD VSS pair, these microcontrollers offer the maximum IO ratio versus pin count. Project migration between the two microcontroller families is facilitated in terms of hardware and software design. The STM32C0 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 meeting new eco-friendly standards while running the application, STM32C0 is a microcontroller of choice. Let us list some typical consumptions. Excellent dynamic consumption below the 48 microamps per megahertz. Sleep mode at 20 microamps per megahertz with flash memory in power down. Stop mode at 80 microamps with all clocks off, 72 microamps with flash in power down. Standby mode at 7.45 microamps with all clocks off. Shutdown mode allows to reach as low as 19 nanoamps if wake-up time is no major constraint. These metrics are provided under the following conditions. 3V power supply and 25°C temperature. This slide compares the STM32C0 and the STM32G0 according to four criteria. Maximum frequency, voltage range, temperature range, smallest and largest package. The STM32C0 integrates the following subsystems. System modules PWR, RCC, RTC, Cystic, GPIO, CRC and CIS CFG. Processor modules Cortex-M0 plus core, MPU, NVIC and ZeroWire debug. DMA controllers supporting three channels. Interconnect based on an HBA light matrix and an HB2APB bridge. Embedded memories, 16 or 32 kilobyte flash memory plus 12 or 6 kilobyte SRAM. Control modules, 116-bit timer that can be used to control a motor, two 16-bit timers with PWM capability and complementary outputs, one 16-bit timer with PWM. Analog modules, temperature sensor, 12-bit ADC. And connectivity modules, one SPI module also supporting I2S, two USARTs, one I2C controllers. Most peripherals can request a DMA transfer to the DMA marks and then the DMA controller in order to transfer data to and from SRAM or flash memory. For instance, characters received by USART1 can be transferred to a buffer in SRAM without software intervention by relying on a DMA channel. This figure indicates for each STM32C0 particular reference the size of integrated memories, flash and SRAM, the package. Thank you for attending this presentation.
