Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KBT6 | Same core, 170 MHz, but only 64 KB Flash, 16 KB SRAM; lacks CCM SRAM and one ADC | Suitable for cost-sensitive motor control where dual ADC oversampling or crypto acceleration is not required | Select when BOM cost reduction outweighs need for AES, dual 16-bit ADCs, or 128 KB Flash firmware headroom |
| STM32F303VCT6 | Cortex-M4F at 72 MHz; no CORDIC/FMAC; 256 KB Flash, 48 KB SRAM; no UCPD or FDCAN | Legacy industrial designs needing higher SRAM but lower compute throughput and no USB-C PD support | Choose only if existing F3 firmware base exists and USB-C/FDCAN integration is unnecessary |
Compared with STM32G431KBT6, the STM32G441VBT6 adds 64 KB Flash, CCM SRAM, and hardware crypto - justifying its use in secure, feature-rich digital power. Against STM32F303VCT6, it delivers 2.4× higher DMIPS, FDCAN, and UCPD - making it the sole choice for next-gen USB-C industrial gateways.

FAQ
What is the maximum operating frequency and associated performance metric for the STM32G441VBT6?
The STM32G441VBT6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), measured per EEMBC benchmark v1.1. This performance is sustained with zero wait states thanks to the ART Accelerator, and includes full DSP instruction support and single-cycle MAC operations - validated across industrial temperature ranges (–40 °C to +85 °C).
Does the STM32G441VBT6 support USB Type-C™ Power Delivery, and how is it implemented?
Yes - the STM32G441VBT6 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It manages CC line signaling, VBUS monitoring/sourcing, and port role negotiation (DFP/UFP) entirely in hardware, eliminating need for external PD controllers. The UCPD peripheral connects directly to GPIOs PA13/PA14 (CC1/CC2) and supports programmable VCONN switching and fault protection.
How many analog-to-digital converters does the STM32G441VBT6 include, and what are their key resolution and speed capabilities?
The device integrates two independent 12/16-bit ADCs (ADC1 and ADC2), each supporting up to 23 input channels and 0.25 µs conversion time. Resolution scales from 12-bit (fastest) to 16-bit (with hardware oversampling up to 256×), achieving effective resolution >15 bits. Both ADCs operate across the full 0–3.6 V input range and support simultaneous sampling, injected conversions, and analog watchdogs - confirmed in DS12960 Rev 5 Section 3.18.
What low-power modes are supported, and what is the minimum current consumption in shutdown mode?
The STM32G441VBT6 supports Sleep, Stop 0/1, Standby, and Shutdown modes. In Shutdown mode (all clocks and regulators disabled except VBAT domain), typical current consumption is 200 nA at 25 °C with RTC and backup registers retained - verified in DS12960 Rev 5 Table 32. Wakeup latency from Shutdown is <10 µs via EXTI or RTC alarm, enabling ultra-low-energy sensor polling.
