STM32H563MIY3QTR, STMicroelectronics 32‑bit High‑Performance MCU (Microcontroller)

TrustZone hardware security: Secure boot and hardware‑based encryption, ideal for devices requiring firmware anti‑tampering protection.

Operating frequency up to 250 MHz, delivering significantly better performance than the F4 series (168 MHz). It features 640 KB RAM, suitable for running complex flight‑control algorithms and attitude calculation.

Compact WLCSP bare‑die‑ball package with minimal PCB footprint, well‑suited for compact drones and portable devices. Requires precise soldering; stencil‑based reflow soldering is mandatory.

H5 series serves as an upgrade replacement for STM32F4 / F7, bringing comprehensive improvements in computing power, RAM size and security.

Applications

Preferred use‑cases

• Main flight‑controller MCU for small‑size drones / racing drones

Advantages: High computing power and large RAM for IMU (ICM‑42688) attitude calculation, PID control and navigation. Tiny WLCSP package fits miniature flight‑controller PCBs. TrustZone provides hardware‑level protection against flight‑controller firmware tampering.

Comparison against legacy solution STM32F405: STM32H563 offers higher computing performance, larger RAM and enhanced security, representing next‑generation flight‑controller MCU.

• Industrial equipment, motor control, AGVs, robot controllers

• High‑security IoT, encrypted gateways, smart portable devices

• Embedded projects demanding compact form‑factor, high computing performance and firmware security

STM32H563MIY3QTR: ST’s new‑generation Cortex‑M33 MCU running at 250 MHz, with 2 MB Flash + 640 KB RAM, compact WLCSP package and hardware TrustZone security. Optimized for next‑generation miniature drone flight controllers as a drop‑in upgrade for STM32F405.
