The STM32H7B0VBT6 is a high-performance microcontroller under the STM32 family, manufactured by Microelectronics.It is based on Arm Cortex-M7 and Cortex-M4 CPUs and comes in a LQFP100 package. This microcontroller supports a range of interfaces, including I2C, SART, SPI, and more. Here's a rudimentary guide to connecting the STM32H7B0VBT6 microcontroller.

1. Power Supply: VDD pins (pins 8, 18, 32, 47, 63, 75, and 86) should be wired into the power source, which can be anywhere between 1.62V and 3.6V. The VSS pins (pins 7, 19, 33, 48, 64, 76, and 87) are ground pins and ought to be linked to the power supply's ground.

2. Boot Configuration: BOOT0 (pin 93) is used to select the boot space at startup. When BOOT0 is tied to VSS, the main Flash memory is selected as boot space, and when tied to VDD, System memory is selected.

3. Input/Output Pins: All the I/O pins from PA0 (pin 13) to PI15 (depending on availability in LQFP100 package) can be configured to handle digital input/output, as well as specific functions like SART, SPI, I2C, etc., according to your application needs.

4. Reset: The NRST pin (pin 9) is the reset pin, which is typically connected to a push-button switch. When grounded, it resets the microcontroller.

5. Oscillator Pins: PF0 and PF1 (pins 29 and 30) are the oscillator pins, which can be connected to an external crystal oscillator if you require a more accurate clock source than the internal one.

The above represents a simplified way of connecting the STM32H7B0VBT6 microcontroller. For a specific application, it is always recommended to refer to the data sheet and the reference manual of the STM32H7B0VBT6. Considerations for bypass/decoupling capacitors, PCB layout, and other specific configurations based on peripheral use should be taken into account for the actual design. The STM32Cube MCU Package for the STM32H7 series embedded software also provides helpful resources.
