Product details

The STM32F103VBH7 is a 32-bit ARM Cortex-M3 MCU running at 72 MHz, with 128 KB of Flash and 20K x 8 SRAM. 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.

Frequently asked questions

What is the closest pin-compatible alternative to STM32F103VBH7?

The STM32F103VBT6 (LQFP-100) is a common pin-compatible alternative within the same STM32F103 family. It shares the same 72 MHz Cortex-M3 core, 128 KB Flash, and 20 KB SRAM, but uses a larger LQFP-100 package instead of the 100-LFBGA. Verify the PCB footprint change before substituting.

What is the operating temperature range for STM32F103VBH7?

The STM32F103VBH7 is rated for -40°C to 105°C ambient, making it suitable for industrial and automotive under-hood environments without additional thermal management.

What compliance documentation does ST provide for STM32F103VBH7?

STMicroelectronics provides RoHS and REACH compliance documentation for this part through its standard product-change notification (PCN) process. The 100-LFBGA package is lead-free and RoHS-compliant per ST's material declaration. Request the full compliance package with your RFQ.
