STMicroelectronics has introduced new fashions in its STM32C0 sequence of 32-bit microcontrollers, the STM32C071 household — providing elevated reminiscence and on-chip USB help.
“We conceived the STM32C0 sequence as an reasonably priced entry level to 32-bit embedded computing,” remembers STMicro’s Patrick Aidoune of the sequence into which the brand new fashions slot. “With bigger reminiscence choices and USB Host/Machine on-chip, the STM32C071 line now provides extra flexibility to improve present purposes and create new merchandise. Additionally, with full help in TouchGFX GUI [Graphical User Interface] software program, these MCUs [Microcontroller Units] simplify elevating consumer experiences with graphics, animation, shade, and contact.”
The brand new STM32C071 components, dropped at our consideration by CNX Software program, use the identical up-to-48MHz 32-bit Arm Cortex-M0+ microcontroller core as the opposite fashions within the STM32C0 vary — however now provide as much as 24kB of static RAM (SRAM) and 128kB of flash storage. An even bigger change is an on-board USB controller, which works with out the necessity for an exterior clock crystal, and is able to working in USB Full-Pace Host and USB Machine modes.
Exact specs rely upon mannequin chosen, with as much as 61 5V-tolerant general-purpose enter/output (GPIO) pins, a five-channel direct reminiscence entry (DMA) controller, 12-bit up-to-19-channel analog to digital converter (ADC), two I2C, two SPI, and two USART buses. All fashions will probably be accessible to order for the following ten years, the corporate has confirmed.

These seeking to experiment with the brand new components can go for a quick-start Nucleo board, the NUCLEO-C071RB, which adopts the acquainted Arduino UNO type issue and hosts a STM32C071RB with 24kB SRAM and 128kB flash — and which features a second USB Sort-C port, for interfacing with the brand new USB controller.
Extra data is offered on the STMicro web site; pricing begins at $0.53 per unit in TSSOP20 and $0.73 in LQFP64 packages, each primarily based on 1,000-unit tray portions, with the event board accessible to order direct from STMicro at $10.19 per unit.
