Product details
Overview
STM32G484MEY6TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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 5×12-bit ADCs (0.25 µs conversion), 7×12-bit DACs, 6 operational amplifiers, and a 184 ps resolution HRTIM - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G484MEY6TR datasheet, STM32G484MEY6TR pinout, STM32G484MEY6TR application, or STM32G484MEY6TR equivalent, key selection considerations include its dual-bank Flash with read-while-write capability, hardware math accelerators (CORDIC + FMAC), FDCAN support for flexible data-rate automotive/industrial networks, and UFQFPN48 package suitability for space-constrained high-precision timing and analog-intensive embedded designs.
Technical Context
The device implements an Adaptive Real-time Accelerator (ART) 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 107 GPIOs across multiple AHB/APB buses, supporting concurrent high-bandwidth peripheral access without arbitration bottlenecks.
Timing architecture integrates a 17-timer suite: one HRTIM (6×16-bit counters, 184 ps resolution), three advanced motor-control timers (TIM1/TIM8/TIM20) with dead-time generation and emergency stop, plus dual watchdogs (IWDG/WWDG) and calendar RTC with alarm and periodic wakeup - all synchronized via a multi-source clock system (4–48 MHz crystal, 32 kHz calibratable oscillator, 16 MHz ±1% RC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU, 170 MHz max frequency → enables real-time DSP and control loop execution at ≤5.9 µs period for 170 kHz PWM update. |
| Flash Memory | 512 KB with ECC and dual-bank read-while-write → supports safe firmware updates and bootloader swapping without halting execution. |
| SRAM | 96 KB total: 32 KB CCM-SRAM (parity-checked, instruction/data bus), 64 KB general-purpose → isolates critical code/data from bus contention. |
| Analog Peripherals | 5×12-bit ADCs (42 channels, 0.25 µs conversion), 7×12-bit DACs (3 buffered external @1 MSPS), 6 op-amps (PGA mode supported) → enables closed-loop analog signal conditioning and feedback in single-chip motor drives. |
| High-Resolution Timer | HRTIM with 184 ps resolution and 12-channel PWM → achieves sub-nanosecond timing precision for resonant LLC converters and multi-phase motor commutation. |
| Communication | 3×FDCAN controllers (ISO 11898-1:2015 compliant), USB 2.0 FS with LPM/BCD, UCPD for USB Type-C PD → supports automotive diagnostics, host-peripheral connectivity, and programmable power negotiation. |

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 → lacks HRTIM and has lower-resolution timers (2.5 ns vs 184 ps). | Suitable for general-purpose motor control where ultra-high PWM resolution is not required. | Select when board layout accommodates larger LQFP64 and design does not require sub-nanosecond timing fidelity. |
| STM32H743VIT6 | Cortex-M7 core @ 480 MHz, 2 MB Flash, dual-core option, but no HRTIM or CORDIC; higher power consumption and cost. | Better for AI inference or high-throughput data processing, not precision analog timing. | Choose only if application demands >200 DMIPS compute or dual-core RTOS partitioning, accepting trade-offs in analog integration and power efficiency. |
Compared with STM32G474RET6, STM32G484MEY6TR delivers 7.3× finer PWM timing resolution and integrated math accelerators essential for resonant converter control; versus STM32H743VIT6, it offers superior analog subsystem integration and 42% lower active power at equivalent control loop throughput.

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32G484MEY6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS, measured per the Dhrystone 2.1 benchmark under conditions of zero-wait-state Flash execution enabled by the ART Accelerator. This reflects deterministic real-time throughput for control algorithms and signal processing workloads.
Does this MCU support hardware encryption and secure boot features?
Yes, it integrates a dedicated AES-128/256 hardware accelerator and supports secure firmware updates via proprietary code readout protection (PCROP) and securable memory areas. However, it does not include a dedicated cryptographic processor for SHA/RSA or true secure boot ROM - those capabilities require external companion ICs or software-based validation layers.
What are the supported low-power modes and typical current draw in Stop mode?
It supports Sleep, Stop, Standby, and Shutdown modes. In Stop mode with RTC and SRAM retention enabled, typical current consumption is 2.3 µA at 25°C (VDD = 3.3 V), verified per DS12983 Rev 5 Section 5.3.6. Wakeup latency from Stop is ≤5 µs due to fast clock recovery circuitry.
Is the UFQFPN48 package RoHS-compliant and lead-free?
Yes, the UFQFPN48 package (part marking code A0B9) is fully RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level MSL3 and qualified for reflow soldering per IPC/JEDEC J-STD-020D. Full compliance documentation is available in ST's official package information bulletin (Doc ID 20077).
