The 100-LFBGA package (10x10 mm) with 80 I/O requires a four-layer PCB with microvia capability. The ball pitch is manageable for a standard SMT line. On-chip peripherals include a 16-channel 12-bit ADC, motor-control PWM timers, DMA, and a temperature sensor. The STM32F103VBH7 is flagged at an EOL hot lifecycle stage. While STMicroelectronics still lists the product status as Active, the broader supply chain signals that this BGA variant is approaching end-of-life. The 72 MHz speed is the ceiling for this Cortex-M3 implementation. The 20K x 8 SRAM (20 KB) is the tightest resource.","metaTitle":"ST STM32F103VBH7 ARM Cortex-M3 MCU, 72MHz, 128KB Flash","metaDescription":"STMicroelectronics STM32F103VBH7 32-bit ARM Cortex-M3 MCU with 72MHz core, 128KB Flash, 20K x 8 SRAM, industrial temp -40°C to 105°C. 100-LFBGA.
