STMicroelectronics STM32F302C8Y6TR

Overview

STM32F302C8Y6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 64 KB Flash, 16 KB SRAM, integrated USB 2.0 full-speed interface, CAN 2.0B controller, and analog peripherals including 12-bit DAC, three rail-to-rail comparators, and one programmable-gain operational amplifier - deployed in motor control, industrial sensing, and USB-connected embedded instrumentation.

For engineers reviewing the STM32F302C8Y6TR datasheet, STM32F302C8Y6TR pinout, STM32F302C8Y6TR application, or STM32F302C8Y6TR equivalent, key selection considerations include its 72 MHz CPU clock with DSP extensions, dual-domain USART with auto-baud detection, capacitive touch sensing support (up to 18 channels), and 5 V-tolerant I/Os on selected pins for mixed-voltage system interfacing.

Technical Context

The device implements an Arm Cortex-M4 core with single-cycle MAC and hardware divide, enabling real-time signal processing in motor control loops and sensor fusion algorithms. Its analog subsystem integrates a 12-bit DAC with dedicated 16-bit basic timer (TIM6), three ultra-fast comparators with internal reference options, and an op-amp configurable as PGA with external feedback network access.

Clock architecture supports multiple sources: 4–32 MHz HSE crystal, 32 kHz LSE for RTC, 8 MHz HSI with PLL multiplication up to 72 MHz, and 40 kHz LSI for watchdog timing. The interconnect matrix enables concurrent peripheral DMA transfers without bus contention across ADC, SPI, I2C, USART, and DAC paths.

Key Specifications

Pinout & Package

STM32F302C8Y6TR is housed in a 48-pin LQFP package (7 × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow ST's standard STM32F302x8 pinout for LQFP48, supporting full peripheral mapping including USB D+/D−, CAN TX/RX, SWDIO/SWCLK debug, and dedicated analog input/output pins.

FAQ

What is the maximum operating temperature range for STM32F302C8Y6TR?

The STM32F302C8Y6TR is qualified for industrial temperature range: –40°C to +85°C. This is confirmed in Section 6.3.1 of DS9896 Rev 8, which specifies ambient operating conditions and thermal derating curves for all power modes. No extended or automotive grade variants exist for this specific part number.

Does STM32F302C8Y6TR support USB device mode only, or can it act as a USB host?

STM32F302C8Y6TR supports USB 2.0 full-speed device mode only - it lacks OTG capabilities or host controller hardware. The USB peripheral is strictly device-side, compatible with CDC, HID, and MSC class drivers when connected to a host PC or embedded host controller. No external PHY or host stack support is provided.

How many independent PWM outputs can be generated simultaneously on this MCU?

Up to 12 independent PWM outputs are possible: TIM1 provides 6 complementary PWM channels with deadtime; TIM2, TIM15, TIM16, and TIM17 each support up to 4 PWM outputs (though not all simultaneously active due to pin mapping constraints). Real-world concurrent count is limited by available GPIOs with alternate function remapping - typically 10–12 channels depending on pin assignment choices.

Is the internal op-amp in STM32F302C8Y6TR unity-gain stable?

Yes, the integrated op-amp is unity-gain stable when configured in non-inverting mode with appropriate external feedback components. Section 3.13 and Table 6.3.21 of DS9896 confirm stability under unity-gain conditions with capacitive loads ≤ 100 pF. For PGA configurations, gain must be ≥ 2 with external resistors to maintain phase margin.
