STM32G491 in STM32 Family
The STM32G491 sub-family, manufactured by STMicroelectronics, is a high-performance mainstream microcontroller line based on the ARM Cortex-M4 core with FPU and DSP instructions. Operating at frequencies up to 170 MHz, these MCUs bridge the gap between standard mainstream series and high-end performance lines. They are specifically engineered for mixed-signal applications, integrating advanced analog peripherals with hardware mathematical accelerators to offload the CPU in complex control loops and signal processing tasks.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| STM32G491MET3 (STMicroelectronics) | 81-pin · LQFP | 1,294 |
Variants within the STM32G491 family primarily differ by package type, pin count, and temperature rating. Packages range from 32-pin UFQFPN to 100-pin LQFP or BGA options, impacting the number of available GPIOs and analog channels. While flash memory remains consistent at 512 KB for this specific sub-family, certain 'M' or 'R' suffixes denote specific pinout configurations and environmental certifications for industrial or extended temperature ranges.
