STMicroelectronics STM32F302VDT6

Overview

STM32F302VDT6 from STMicroelectronics is a 32-bit ARM® Cortex®-M4 microcontroller with FPU, operating at up to 72 MHz, featuring 512 KB Flash, 64 KB SRAM (with HW parity on first 32 KB), and integrated analog peripherals including two 12-bit ADCs (18-channel, 0.20 µs conversion), one 12-bit DAC, four rail-to-rail comparators, and two operational amplifiers usable in PGA mode - deployed in motor control, industrial sensing, and digital power supply systems.

For engineers reviewing the STM32F302VDT6 datasheet, STM32F302VDT6 pinout, STM32F302VDT6 application, or STM32F302VDT6 equivalent, key selection considerations include its dual ADC architecture with independent analog supplies (2.0–3.6 V), flexible FSMC interface for external memory expansion, CAN 2.0B support, and capacitive touch sensing capability across up to 24 channels.

Technical Context

The device implements an ARM Cortex-M4 core with hardware floating-point unit, single-cycle multiply, and DSP instruction set, paired with a memory protection unit (MPU) for secure task isolation. Its clock system integrates multiple oscillators: 4–32 MHz HSE, 32 kHz LSE for RTC, 8 MHz HSI with PLL, and 40 kHz LSI - enabling precise timing control across low-power and high-performance modes.

Analog subsystem integration includes dedicated voltage domains: VDDA (2.0–3.6 V) for ADCs/comparators, VREFOPAMP and VREFINT references, and separate 2.4–3.6 V supply for DAC and op-amps. The interconnect matrix enables concurrent peripheral access without bus contention, supporting real-time deterministic response in closed-loop control applications.

FAQ

What is the maximum operating frequency and supported voltage range for STM32F302VDT6?

The STM32F302VDT6 operates at up to 72 MHz using its internal PLL and supports a VDD/VDDA supply range of 2.0 V to 3.6 V. It includes programmable voltage detection (PVD) to monitor supply levels and trigger interrupts or resets before brown-out conditions affect analog accuracy or Flash reliability.

Does STM32F302VDT6 support external memory interfaces, and which types are compatible?

Yes, it integrates a Flexible Static Memory Controller (FSMC) supporting asynchronous/synchronous NOR, PSRAM, NAND Flash, and PC Card/CompactFlash interfaces via four chip-select outputs. This enables direct connection to external displays, data loggers, or FPGA co-processors without additional glue logic.

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

The device integrates two 12-bit ADCs (18-channel, 0.20 µs conversion time, 0–3.6 V range), one 12-bit DAC (2.4–3.6 V analog supply), four rail-to-rail comparators, and two operational amplifiers with PGA capability. All analog blocks feature independent supply domains and internal references (VREFINT, VREFOPAMP) for stable operation.

Is STM32F302VDT6 qualified for industrial temperature range, and what packaging is used?

Yes, STM32F302VDT6 is specified for the industrial temperature range (–40 °C to +85 °C) and is supplied in LQFP64 package (10 × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package supports reflow soldering and provides adequate thermal dissipation for continuous 72 MHz operation in enclosed enclosures.
