Product details

Overview

STM32G474CCU6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating 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 a 184 ps resolution HRTIM - deployed in motor control, digital power conversion, and industrial sensing systems.

For engineers reviewing the STM32G474CCU6 datasheet, STM32G474CCU6 pinout, STM32G474CCU6 application, or STM32G474CCU6 equivalent, key selection criteria include HRTIM timing precision for PWM generation, dual-bank Flash with read-while-write for firmware updates, CORDIC/FMAC hardware acceleration for real-time math, and UCPD support for USB Type-C™ power delivery implementation.

Technical Context

The STM32G474CCU6 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 supports concurrent high-bandwidth peripheral access without bus contention.

It integrates three FDCAN controllers compliant with ISO 11898-1:2015 for flexible data-rate automotive and industrial networking, alongside a dedicated USB Type-C™/Power Delivery (UCPD) controller with VBUS monitoring and role swap support - distinguishing it from standard USB FS interfaces.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance mixed-signal MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32G474RET6	LQFP64 package (64-pin), adds 16 more GPIOs and 2 additional ADC channels vs. UFQFPN48; same core/peripherals.	Better suited for designs requiring expanded analog acquisition or complex I/O mapping - e.g., multi-axis motion controllers.	Select when board layout allows larger footprint and additional I/O or ADC resources are needed; pin-compatible peripheral register map.
STM32G431CBU6	Same UFQFPN48 package but reduced resources: 128 KB Flash, 32 KB SRAM, no CORDIC/FMAC, single ADC, no UCPD.	Targeted at cost-sensitive motor control or power conversion where advanced math acceleration or USB PD is unnecessary.	Choose for simplified BOM and lower unit cost where HRTIM, dual ADC, or UCPD features are unused - not drop-in compatible due to peripheral disable.

Compared with STM32G474RET6, the STM32G474CCU6 offers identical performance in a space-constrained 7×7 mm package but trades I/O count for PCB area savings; versus STM32G431CBU6, it delivers full G4-series feature set including hardware math engines and triple FDCAN - critical for next-generation digital power and USB-C ecosystems.

FAQ

What is the maximum operating temperature range for STM32G474CCU6?

The STM32G474CCU6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 5.3.1 of DS12288 Rev 6, specifying operating conditions for all G474xC variants including CCU6. Thermal derating begins above 85 °C ambient, and junction temperature must remain below 125 °C per absolute maximum ratings.

Does STM32G474CCU6 support hardware encryption acceleration?

No, the STM32G474CCU6 does not include a dedicated cryptographic accelerator (e.g., AES, SHA, PKA). It relies on software libraries or optional external secure elements. The device features a True Random Number Generator (RNG) and 96-bit unique ID for key derivation, but no hardware AES engine - unlike STM32L5 or STM32H7 series.

Can the HRTIM module generate complementary PWM signals with programmable dead time on STM32G474CCU6?

Yes. The HRTIM module provides six independent timers with complementary output pairs (e.g., CH1A/CH1B), each supporting fully programmable dead-time insertion (184 ps resolution), fault input handling, and emergency shutdown - all implemented in hardware without CPU intervention, as detailed in Section 3.24.1 of the datasheet.

Is the STM32G474CCU6 pin-compatible with other STM32G474x packages like LQFP48?

No. While electrical functionality is identical, the UFQFPN48 (CCU6) and LQFP48 (CCY6) packages have different pinouts. For example, HRTIM outputs and UCPD pins are assigned to distinct locations. Pin mapping must be verified against Sections 4.1 and 4.2 of DS12288 Rev 6 - mechanical compatibility does not imply electrical pin equivalence.
