Product details
Overview
STM32G484CEU6 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, 96 KB SRAM (including 32 KB CCM-SRAM with parity), 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 high-resolution timer (HRTIM) with 184 ps resolution-used in precision motor control and digital power conversion systems.
For engineers reviewing the STM32G484CEU6 datasheet, STM32G484CEU6 pinout, STM32G484CEU6 application, or STM32G484CEU6 equivalent, key selection considerations include HRTIM timing precision for PWM dead-time control, dual-bank Flash with read-while-write for firmware updates, hardware CORDIC/FMAC accelerators for real-time trigonometric and filtering operations, and FDCAN support for automotive-grade communication.
Technical Context
The STM32G484CEU6 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix routes up to 107 GPIOs-including 5 V-tolerant pins-to multiple peripherals without contention.
It integrates three FDCAN controllers supporting flexible data-rate (CAN FD), USB 2.0 full-speed with LPM/BCD, and a dedicated UCPD interface for USB Type-C™ power delivery negotiation-enabling single-chip USB-C PD sink/source designs with real-time analog control.

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/peripherals but 512 KB Flash, 128 KB SRAM, LQFP64 package; no UCPD or HRTIM | Lacks USB-C PD and ultra-high-res PWM-unsuitable for USB-C adapters or precision motor drives | Select when higher SRAM and standard timers suffice, and USB-C or sub-ns PWM are not required |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB Flash, 1 MB RAM, dual-core option; no CORDIC/FMAC, different analog subsystem | Targeted at high-throughput applications (e.g., GUI, AI inference); lacks G4's analog integration and HRTIM precision | Choose for compute-heavy tasks where analog co-processing and nanosecond PWM timing are secondary |
Compared with STM32G474RET6, the STM32G484CEU6 adds UCPD and HRTIM for USB-C PD and motor control, while STM32H743VIT6 trades analog richness for raw CPU performance-making the G484CEU6 optimal for mixed-signal real-time edge control where timing, security, and integration density are critical.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating?
The STM32G484CEU6 operates at up to 170 MHz with an ART Accelerator enabled, delivering 213 DMIPS (Dhrystone MIPS). This performance is sustained with zero wait states from Flash memory due to the 4-KB instruction cache and prefetch buffer, verified under VDD = 3.3 V and TA = 25 °C per DS12983 Rev 5 Section 5.3.9.
Does STM32G484CEU6 support USB Type-C™ Power Delivery?
Yes-it integrates a dedicated USB Type-C™ and Power Delivery controller (UCPD) compliant with USB PD 3.0, supporting CC line monitoring, VCONN switching, and PD message handling without external ICs. The UCPD peripheral is electrically isolated and includes built-in fault protection per Section 3.36 of the datasheet.
How many ADC channels and what is the fastest conversion time?
The device features five independent 12-bit ADCs supporting up to 42 total channels. The fastest conversion time is 0.25 µs (4 MSPS) in single-ended mode with synchronous sampling, achieved using the hardware oversampling feature to enhance effective resolution up to 16 bits-detailed in Section 3.18 and Table 5.3.19.
What low-power modes are supported and what is the lowest current draw?
Seven low-power modes are supported: Sleep, Stop, Standby, Shutdown, Low-power Run, Low-power Sleep, and Low-power Stop. In Shutdown mode with VBAT powered and RTC running, typical current consumption is 20 nA at 25 °C (Section 5.3.4), making it suitable for battery-backed real-time clock and tamper-detection applications.
