The STMicroelectronics STM32F103VGT6TR is a 32-bit ARM Cortex-M3 MCU clocked at 72 MHz, packing 1 MB of Flash and 96 KB of SRAM in a 100-LQFP package. It belongs to the STM32F1 series, a widely deployed family for industrial control, motor drives, and embedded systems that need a balance of processing throughput, memory, and peripheral integration. The 72 MHz core delivers enough headroom for real-time control loops and protocol stacks without pushing the silicon to its timing wall.
1 MB program memory — firmware footprint and field updates
With 1 MB of Flash, this MCU can hold a full application stack plus a bootloader for over-the-air or field-bus firmware updates. The 96 KB SRAM supports moderate-size data buffers and real-time variable storage — enough for a CANopen stack with a few hundred PDO mappings or a USB mass-storage class implementation without external RAM.
Industrial temperature grade — deployment environment
Supply range is 2 V to 3.6 V.
