Three new microcontrollers (MCUs) are joining STMicroelectronics’ STM32C0 series, giving designers more flexibility with options including greater memory density, extended interfaces, and CAN FD for enhanced communication capability.
The new MCUs now joining the cost-efficient series include the STM32C051, with up to 64KByte of Flash for applications that need more storage than STM32C031 MCUs can provide. Additional features include extra interfaces and more user I/O channels in packages with up to 48 pins.
Also new, the STM32C091 and STM32C092 extend Flash density up to 256KByte in packages up to 64 pins, adding a CAN FD interface in the STM32C092. With CAN FD on-chip, users can trim the BOM and simplify the hardware design of industrial communication and networking devices, leveraging the upgraded protocol’s flexibility, speed, and payload capacity.
“The STM32C0 series offers great flexibility as a cost-conscious line in the STM32 family, with memory ranging from 32Kbyte to 256Kbyte of Flash and rich peripherals,” commented Patrick Aidoune, General Purpose MCU Division General Manager, STMicroelectronics. “The large Flash and RAM now available in the STM32C091/C092 let designers host the graphical user interface alongside the main application, leveraging ST’s TouchGFX tools to create entertaining experiences and streamline development.”
As the most affordable entry point to the STM32 family, STM32C0 MCUs contain widely used interfaces such as crystal-less USB Full Speed Device and USARTs, as well as timers and an analog/digital; converter (ADC). Complementing the cost-conscious feature set, the economical design with on-chip clocks and just one power-supply input saves additional external components including timing and decoupling from the bill of materials (BOM). Further, these savings enable a smaller, simpler PCB design.
All STM32C0 MCUs come with extra benefits for developers, including ST’s extended longevity program that ensures long-term availability throughout the lifetime of industrial projects. As members of the high-quality STM32 family, designing with STM32C0 MCUs also eases compliance with product-level approvals such as IEC 61508 for functional safety. The devices contain the Arm® Cortex®-M0+ core that also powers STM32G0 MCUs, which are designed for higher performance and advanced features. The two STM32 MCU series share many aspects including package styles and pinout, and peripheral IP, enabling designs to migrate easily between the two.
