STM32F302R8T6 概要
A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It contains a processor core, memory, and programmable input/output peripherals. The STM32F302R8T6 belongs to the STM32F3 family, which is optimized for analog and mixed-signal control applications, bridging the gap between general-purpose MCUs and digital signal processors (DSPs).
Key features include a 64 MHz ARM Cortex-M4F core with FPU, 64 KB flash, 16 KB SRAM, and a rich set of analog peripherals: two 12-bit DACs, three 12-bit ADCs (up to 5 MSPS), and an operational amplifier. It also integrates a 16-bit advanced-control timer, multiple general-purpose timers, and a real-time clock. Communication interfaces include I2C, SPI, USART, and CAN, making it versatile for industrial and consumer applications.
The STM32F302R8T6 leverages the ARM Cortex-M4F architecture with DSP instructions and a single-precision FPU, enabling efficient execution of complex algorithms. The device operates from a 2.0V to 3.6V power supply and supports a temperature range of -40°C to +85°C. Its advanced analog peripherals allow for high-resolution signal acquisition and generation, reducing external component count.
Typical applications include motor control, power management, industrial automation, and consumer electronics. The combination of high-speed ADC, DAC, and op-amp makes it ideal for closed-loop control systems, such as field-oriented control (FOC) of brushless DC motors. The CAN interface supports robust communication in automotive and industrial networks.
When designing with this MCU, ensure proper decoupling of the power supply pins and a stable clock source. The internal 8 MHz RC oscillator can be used for basic operation, but an external crystal is recommended for applications requiring precise timing. The device supports in-circuit programming and debugging via SWD, simplifying firmware development.

設計ノート
Decouple all VDD and VDDA pins with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 4.7uF capacitor on VDDA for analog noise filtering. The VREF+ pin should be connected to a clean reference voltage, typically 3.3V, with a 1uF capacitor to ground. Proper decoupling is critical for ADC accuracy and stable operation.
For the LQFP-64 package, ensure a solid ground plane under the device. Route the crystal oscillator (if used) with short traces and keep it away from high-speed digital signals. Place the boot configuration resistors (BOOT0 and BOOT1) with pull-downs to ensure reliable startup. Use a 4-layer PCB for optimal EMC performance.
Do not exceed the absolute maximum ratings: VDD max 3.6V, and any I/O pin voltage must be within VSS-0.3V to VDD+0.3V. Ensure the NRST pin is pulled high with a 100nF capacitor to ground for reliable reset. When using the ADC, avoid floating input pins by configuring them as analog inputs. For CAN communication, terminate the bus with 120 ohm resistors at both ends.
