STMicroelectronics STM32F302VCY6TR

Overview

STM32F302VCY6TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 72 MHz, featuring 256 KB Flash, 40 KB SRAM (16 KB with HW parity), dual 12-bit ADCs (0.20 µs conversion), one 12-bit DAC, four rail-to-rail comparators, and two programmable-gain operational amplifiers. It integrates CAN 2.0B, USB 2.0 FS, five USARTs, three SPIs/I2S, two I2C, RTC with alarm, and capacitive touch sensing - deployed in industrial motor control, digital power supplies, and analog signal conditioning systems.

For engineers reviewing the STM32F302VCY6TR datasheet, STM32F302VCY6TR pinout, STM32F302VCY6TR application, or STM32F302VCY6TR equivalent, key selection considerations include its integrated analog front-end (dual ADCs + DAC + PGAs + COMP), 72 MHz real-time performance with FPU, 2.0–3.6 V supply range, LQFP100 package compatibility, and support for deterministic control loops in closed-loop power electronics.

Technical Context

The device implements a tightly coupled Cortex-M4 core with single-cycle multiply, hardware divide, DSP extensions, and MPU-enabling deterministic execution of motor control algorithms and real-time signal processing. Its analog subsystem includes two independent 12-bit ADCs with selectable resolution (6/8/10/12 bits), differential input capability, and dedicated 2–3.6 V analog supply domain.

Clock architecture supports multiple sources: 4–32 MHz HSE crystal, 32 kHz LSE for RTC, 8 MHz HSI with PLL (up to 72 MHz), and 40 kHz LSI. The interconnect matrix enables concurrent peripheral access without bus contention, critical for simultaneous ADC sampling, PWM generation, and CAN messaging.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32F302VCY6TR operates at up to 72 MHz using its internal PLL driven by HSE or HSI clocks. Its VDD and VDDA supply range is strictly 2.0 V to 3.6 V, with separate analog and digital domains. Operation outside this range risks functional failure or permanent damage, and the device includes a programmable voltage detector (PVD) to trigger interrupts or resets during brown-out conditions.

Does it support hardware CRC calculation and memory protection?

Yes, it integrates a dedicated CRC calculation unit compliant with IEEE-802.3 polynomial (0x04C11DB7) for fast checksum generation on data buffers or firmware images. It also includes a Memory Protection Unit (MPU) supporting eight configurable regions with subregion disable, enabling privilege-level isolation between application tasks and kernel code - essential for IEC 61508 SIL2-certifiable firmware architectures.

How many analog peripherals are integrated and what are their key electrical specs?

It integrates two 12-bit ADCs (0.20 µs conversion, 17-channel, 0–3.6 V range), one 12-bit DAC (2.4–3.6 V analog supply), four rail-to-rail comparators (<100 ns propagation delay), and two operational amplifiers configurable as PGAs (gain up to 32×). All analog blocks share independent supply domains (VDDA/VSSA) and support hardware calibration for offset/gain error correction per datasheet Section 6.3.18–6.3.21.

Is the LQFP100 package RoHS-compliant and what is its thermal performance?

Yes, the LQFP100 package (14 × 14 mm, 0.5 mm pitch) is RoHS-compliant and rated for industrial temperature range (–40°C to +85°C). Its thermal resistance θ_JA is 30°C/W (typical, JEDEC standard board), and it features an exposed thermal pad for enhanced heat dissipation. For sustained 72 MHz operation with active peripherals, PCB layout must include ≥4 thermal vias under the pad connected to an internal ground plane.
