Product details

This is the mainstream-density member of the family, sized for control applications that need a real-time core with a balanced memory budget — motor drives, field-sensor nodes, and CAN-linked industrial peripherals are its typical deployment.

Industrial temperature and BGA footprint

The 64-TFBGA (5x5 mm) package saves board area versus a TQFP-64 but requires controlled-impedance layout and X-ray inspection for BGA solder joints — a factor for assembly yield planning.

Peripherals and connectivity set

On-chip peripherals include DMA, motor-control PWM, programmable voltage detector (PVD), power-on reset (POR), and a temperature sensor.

Frequently asked questions

What is the difference between STM32F103R8H7 and STM32F103RBT7?

Both are STM32F103 series ARM Cortex-M3 MCUs in a 64-TFBGA package. The R8H7 has 64 KB Flash and 20 KB RAM; the RBT7 has 128 KB Flash and 20 KB RAM. The extra 64 KB Flash on the RBT7 supports larger firmware images — otherwise the peripheral set, pinout, and supply range are identical.
