Overview
STM32G473PCI6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six rail-to-rail op-amps, and hardware math accelerators (CORDIC, FMAC). It targets motor control, digital power conversion, and industrial sensing systems requiring real-time signal processing and high-precision analog I/O.
For engineers reviewing the STM32G473PCI6 datasheet, STM32G473PCI6 pinout, STM32G473PCI6 application, or STM32G473PCI6 equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, 107 fast I/Os (5 V tolerant on selected pins), FDCAN support for flexible data-rate automotive/industrial networks, UCPD interface for USB Type-C™ power delivery, and low-power timer with sub-microsecond resolution for energy-constrained edge devices.
Technical Context
The STM32G473PCI6 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) for secure task isolation. Its interconnect matrix routes up to 16 DMA channels across multiple AHB/APB buses, supporting concurrent peripheral access without arbitration bottlenecks.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015, supporting CAN FD frames up to 5 Mbit/s, alongside a dedicated USB Type-C™ Power Delivery controller (UCPD) with hardware PD protocol engine and VBUS monitoring - enabling single-chip USB-C port management in embedded chargers and docking stations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same core, Flash, RAM, and peripherals; differs only in package (LQFP64 vs LQFP100) and pin count (64 vs 100) | Fewer GPIOs, ADC channels, and timer outputs; lacks second FDCAN and UCPD interface | Select when board space is constrained and full peripheral set is not required - reduces BOM cost by ~12% |
| STM32H743VIT6 | Higher-performance Cortex-M7 (480 MHz), 2 MB Flash, dual-core option, but no UCPD or CORDIC; larger LQFP100 footprint with different pinout | Targeted at complex HMI and AI-edge inference; lacks native USB-C PD support and analog acceleration blocks | Choose only if >200 DMIPS and external DDR are mandatory - adds complexity, cost, and power overhead for G4-class applications |
Compared with STM32G474RET6, the STM32G473PCI6 offers 36 additional I/Os, full FDCAN triple redundancy, and UCPD - essential for USB-C PD hubs and multi-axis motor drives. Versus STM32H743VIT6, it delivers superior analog integration and lower active power at 170 MHz, making it optimal for cost-sensitive, analog-intensive real-time control.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the STM32G473PCI6?
The STM32G473PCI6 operates at a maximum CPU frequency of 170 MHz, delivering 213 DMIPS (Dhrystone MIPS) as measured per the ARM Dhrystone benchmark v2.1. This performance is sustained with zero-wait-state execution from Flash memory thanks to the integrated ART Accelerator, and includes full DSP instruction support and single-precision floating-point unit (FPU) acceleration.
Does the STM32G473PCI6 support USB Power Delivery (PD) negotiation natively?
Yes - the STM32G473PCI6 integrates a dedicated USB Type-C™ and Power Delivery controller (UCPD) compliant with USB PD 3.0 specification. It includes hardware PD protocol engine, VBUS discharge circuitry, CC line monitoring, and role-swap logic, enabling full PD contract negotiation (including Programmable Power Supply) without external PD controller ICs or software stack overhead.
How many analog-to-digital converters (ADCs) does the STM32G473PCI6 feature, and what are their key timing specifications?
The STM32G473PCI6 integrates five independent 12-bit ADCs with up to 42 total input channels. Each ADC achieves 0.25 µs conversion time (4 MSPS sampling rate), supports hardware oversampling up to 16-bit resolution, and features fully synchronous triggering via advanced timers - enabling precise current/voltage sampling in motor control and power supply applications.
Is the STM32G473PCI6 pin-compatible with other members of the STM32G473 family?
No - the STM32G473PCI6 uses the LQFP100 package (100-pin), whereas other variants like STM32G473CBT6 (LQFP48) or STM32G473CCT6 (LQFP64) have different pin counts and layouts. While they share identical peripheral sets and register-level compatibility, physical pin mapping is not interchangeable; PCB layout must be designed specifically for the LQFP100 footprint and signal routing requirements.
