The STM32F100R8H7B: It carries 64 KB of Flash and 8K x 8 of SRAM.
On the peripheral side you get DMA, a programmable voltage detector (PVD), power-on/power-down reset (POR/PDR), a temperature sensor, a watchdog timer, and PWM-capable timers. The 51 I/O pins in the 64-TFBGA package give you headroom for parallel displays or a bank of switched outputs.
The 64-TFBGA (5x5 mm) is a fine-pitch BGA.
It is suitable for outdoor, factory-floor, and under-hood environments.
The STM32F100R8H6B is a different package variant within the same base product number family (STM32F100). The H7B suffix indicates the 64-TFBGA package; the H6B would be a different BGA or LQFP variant. They are not pin-compatible without a board spin. Check the specific package code on your current BOM before substituting.
