STMicroelectronics STM32F302VET6TR

Overview

STM32F302VET6TR from STMicroelectronics is an ARM® Cortex®-M4 32-bit 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 configurable as PGAs. It targets motor control, industrial sensing, and human-machine interface applications requiring mixed-signal processing and real-time responsiveness.

For engineers reviewing the STM32F302VET6TR datasheet, STM32F302VET6TR pinout, STM32F302VET6TR application, or STM32F302VET6TR equivalent, key selection considerations include its LQFP100 package, 2.0–3.6 V supply range, CAN 2.0B interface, FSMC for external memory expansion, and capacitive touch sensing support across 24 channels.

Technical Context

The device integrates a Cortex-M4 core with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time execution and secure memory partitioning. Its analog subsystem includes dual independent ADCs with selectable resolution (6/8/10/12 bits) and separate analog supply (2.0–3.6 V), plus a dedicated 12-bit DAC with 2.4–3.6 V analog supply.

Clock architecture supports multiple sources: 4–32 MHz HSE crystal, 32 kHz LSE for RTC, 8 MHz HSI with PLL multiplication, and 40 kHz LSI. Peripheral interconnect matrix enables flexible routing of DMA, timers, and communication interfaces-including three I²C (Fast Mode Plus), five USART/UART, four SPI/I²S, USB 2.0 FS, and CAN 2.0B-without resource contention.

FAQ

What is the maximum operating frequency and does it require external clock circuitry?

The STM32F302VET6TR operates at up to 72 MHz using its internal 8 MHz HSI oscillator multiplied by the PLL. An external 4–32 MHz crystal (HSE) is optional but recommended for applications requiring precise timing (e.g., USB or RTC calibration). The device also supports 32.768 kHz LSE for RTC accuracy and internal 40 kHz LSI for watchdog independence.

Does this MCU support hardware encryption or secure boot features?

No, the STM32F302VET6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. It lacks tamper detection, secure memory isolation, or embedded secure element functionality. For security-critical applications, ST recommends the STM32L5 or STM32H5 series, which integrate Arm TrustZone and dedicated crypto peripherals.

Can the op-amps be configured as instrumentation amplifiers or only as PGAs?

The two operational amplifiers support programmable-gain amplifier (PGA) mode with gains of 1, 2, 4, 8, 16, or 32 via internal resistor networks, but they cannot be externally wired as three-op-amp instrumentation amplifiers. Their inputs and outputs are fully accessible, allowing external feedback configurations-but no dedicated INAMP topology or laser-trimmed resistor matching is provided.

Is the FSMC interface compatible with standard parallel NOR flash devices?

Yes, the FSMC supports asynchronous non-multiplexed NOR flash with up to 64 MB address space, configurable wait states, and hardware NWAIT assertion. It complies with JEDEC standards for common parallel NOR devices (e.g., Spansion S29GL, Macronix MX29LV), including read/write timing parameters documented in Section 6.3.11 of the datasheet (DocID026900 Rev 4).
