The new STM32C071 microcontroller expands flash memory and RAM capacity, adds a USB controller, and supports TouchGFX graphics software, making end products thinner, more compact, and more competitive.
Now, STM32 developers can access more storage space and additional features on the STM32C0 microcontroller (MCU), enabling more advanced functionalities in resource-constrained and cost-sensitive embedded applications.
The STM32C071 MCU is equipped with up to 128KB of flash memory and 24KB of RAM, and it introduces a USB device that does not require an external crystal oscillator, supporting TouchGFX graphics software. The on-chip USB controller allows designers to save at least one external clock and four decoupling capacitors, reducing bill of materials costs and simplifying PCB component layout. Additionally, the new product only requires a pair of power lines, which helps streamline PCB design. This allows for thinner, neater, and more competitive product designs.
The STM32C0 MCU uses the Arm® Cortex®-M0+ core, which can replace traditional 8-bit or 16-bit MCUs in products such as home appliances, simple industrial controllers, power tools, and IoT devices. As an economical option among 32-bit MCUs, the STM32C0 offers higher processing performance, larger storage capacity, greater peripheral integration (suitable for user interface control and other functions), as well as essential control, timing, computation, and communication capabilities.
Moreover, developers can accelerate application development for the STM32C0 MCU with the robust STM32 ecosystem, which provides a variety of development tools, software packages, and evaluation boards. Developers can also join the STM32 user community to share and exchange experiences. Scalability is another highlight of the new product; the STM32C0 series shares many common features with the higher-performance STM32G0 MCU, including the Cortex-M0+ core, peripheral IP cores, and compact pin arrangements with optimized I/O ratios.
Patrick Aidoune, General Manager of STMicroelectronics’ General MCU Division, stated: “We position the STM32C0 series as an economical entry-level product for 32-bit embedded computing applications. The STM32C071 series features larger on-chip storage capacity and a USB device controller, providing developers with greater design flexibility to upgrade existing applications and develop new products. Additionally, the new MCU fully supports TouchGFX GUI software, making it easier to enhance user experience with graphics, animations, colors, and touch functionalities.”
Two customers of the STM32C071, Dongguan TSD Display Technology in China and Riverdi Sp in Poland, have completed their first projects using the new STM32C071 MCU. Both companies are authorized partners of ST.
TSD Display Technology selected the STM32C071 to control an entire module for a 240x240 resolution knob display, including a 1.28-inch circular LCD display and position-encoding electronic components. Roger L.J., Chief Operating Officer of TSD Display Technology, stated: “This MCU offers great value for money and is easy for developers to use, allowing us to provide a competitively priced transformative product for the home appliance, smart home device, automotive control, beauty device, and industrial control markets.”
Kamil Kozłowski, Co-CEO of Riverdi, introduced the company’s 1.54-inch LCD display module, which features high clarity and brightness while maintaining extremely low power consumption. “The simplicity and cost-effectiveness of the STM32C071 enable customers to easily integrate the display module into their own projects. This module can connect directly to the STM32 NUCLEO-C071RB development board and leverage the powerful ecosystem to create a TouchGFX graphical demonstration project.”
The STM32C071 MCU is now in production. STMicroelectronics’ long-term supply plan ensures that the STM32C0 MCU will be available for ten years from the date of purchase to support ongoing production and field maintenance needs.
