STMicroelectronics STM32G0C1RCI6N

Overview

STM32G0C1RCI6N from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 256 KB flash, 144 KB SRAM, dual 12-bit DACs, two FDCAN controllers, and USB Type-C™ Power Delivery controller - deployed in industrial HMI, smart metering gateways, and USB-C PD-enabled embedded power management systems.

For engineers reviewing the STM32G0C1RCI6N datasheet, STM32G0C1RCI6N pinout, STM32G0C1RCI6N application, or STM32G0C1RCI6N equivalent, key selection criteria include FDCAN interface count, USB-C PD controller integration, 125°C extended temperature rating, and 64-pin LQFP package with 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

This MCU integrates a single-core Arm Cortex-M0+ running up to 64 MHz, with memory protection unit (MPU), dual-bank flash supporting read-while-write, and hardware AES-128/256 acceleration. It features two independent FDCAN 2.0B controllers with time-triggered communication support and a dedicated USB Type-C Power Delivery PHY + policy engine.

Clock architecture includes four oscillators (HSE/LSE/HSI16/HSI48), programmable voltage detector (PVD), and six low-power modes (Stop 0/1, Standby, Shutdown) with RTC and tamper detection. The 64-pin LQFP package supports 51 fast I/Os, 12-channel DMA, and 16-channel 12-bit ADC with hardware oversampling up to 16-bit resolution.

FAQ

What is the maximum operating temperature of the STM32G0C1RCI6N?

The STM32G0C1RCI6N is rated for operation from −40°C to +125°C, validated per JEDEC JESD22-A108 and qualified for automotive-grade extended temperature environments. This rating applies across all operating modes including full-speed execution and peripheral activation, with thermal derating curves documented in Section 6.13 of DS13564 Rev 5.

Does the STM32G0C1RCI6N support crystal-less USB Full-Speed operation?

Yes, the STM32G0C1RCI6N integrates an internal 48 MHz RC oscillator (HSI48) trimmed to ±0.25% accuracy, enabling USB 2.0 Full-Speed device mode without an external crystal. This is confirmed in Section 3.9 and Table 45 of DS13564 Rev 5, reducing bill-of-materials cost and PCB layout complexity.

How many FDCAN controllers does the STM32G0C1RCI6N include, and what standards do they support?

The STM32G0C1RCI6N includes two fully independent FDCAN 2.0B controllers supporting ISO 11898-1:2015 with bit rates up to 5 Mbps, time-triggered communication (TTCAN), and flexible data-rate (FD) frames. Each controller has dedicated TX/RX pins and supports loopback, self-test, and error confinement modes per Section 3.28 of the datasheet.

Is the USB Type-C Power Delivery controller on the STM32G0C1RCI6N a standalone hardware block?

Yes, the USB-C PD controller is a dedicated hardware subsystem comprising BMC physical layer, policy engine, and VCONN switch control - fully autonomous from the Cortex-M0+ core. It operates independently during sleep modes and handles PD negotiation, fault recovery, and role swapping without CPU intervention, as detailed in Section 3.27 of DS13564 Rev 5.
