STM32F439 in STM32 Family
The STM32F439 sub-family by STMicroelectronics represents the high-performance tier of the Cortex-M4 portfolio, specifically designed for applications requiring significant memory and advanced security. Based on the Arm Cortex-M4 core with a Floating Point Unit, these microcontrollers operate at frequencies up to 180 MHz. They are widely utilized in industrial gateways, sophisticated human-machine interfaces, and secure connected devices where the integrated cryptographic acceleration and Chrom-ART Accelerator provide a competitive edge in processing efficiency and graphics performance.
Variants in This Sub-Family
Variants within the STM32F439 sub-family primarily differ based on package size and Flash memory density, ranging from 1 MB to 2 MB. Package options include LQFP100, LQFP144, LQFP176, and BGA configurations like the UFBGA169 and WLCSP. Higher pin-count packages offer increased GPIO availability and support for the full external memory interface (FSMC), while smaller footprints cater to space-constrained industrial sensors and portable devices.
