It holds a CANopen stack, USB HID or CDC class, and a motor-control loop, but leaves no room for over-the-air update staging. ## 20 KB SRAM — watch the stack and buffers 20 KB of SRAM is adequate for a single control loop with moderate data logging, but it fills fast when you enable USB buffers, a TCP/IP stack, or multiple DMA channels. Budget the RAM early in the design phase — the 20 KB is shared across all peripherals and the Cortex-M3 stack. ## 100-ball LFBGA — board assembly note The 100-LFBGA package requires X-ray inspection for solder-joint verification and a controlled reflow profile. Store the trays in a dry cabinet — BGA packages are moisture-sensitive and need baking if the seal is broken. ## Peripheral set — motor control and fieldbus ready The built-in motor control PWM timers, DMA controller, and CAN interface make this part a fit for a servo drive or VFD auxiliary controller. The USB full-speed device interface handles firmware updates without a separate UART-to-USB bridge. ## Lifecycle and sourcing — EOL notice in effect The STM32F103VBH6 carries an end-of-life (EOL) status.","metaTitle":"ST STM32F103VBH6 ARM Cortex-M3 MCU, 72 MHz, 128 KB Flash","metaDescription":"STM32F103VBH6 32-bit MCU with 72 MHz core, 128 KB Flash, 20 KB RAM, 80 I/O, CAN/USB/SPI/I2C, -40 to 85°C, 100-LFBGA.
