STMicroelectronics STM32F303VEH7TR

Overview

STM32F303VEH7TR from STMicroelectronics is an ARM® Cortex®-M4 32-bit microcontroller with FPU, operating at up to 72 MHz, featuring 512 KB Flash, 80 KB SRAM (64 KB + 16 KB CCM), and integrated analog peripherals including four operational amplifiers, seven comparators, two 12-bit DACs, and four ADCs (12/10/8/6-bit selectable resolution). It supports CAN 2.0B, USB 2.0 FS, and capacitive touch sensing - deployed in industrial motor control and digital power supply feedback loops.

For engineers reviewing the STM32F303VEH7TR datasheet, STM32F303VEH7TR pinout, STM32F303VEH7TR application, or STM32F303VEH7TR equivalent, key selection criteria include its dual DAC channels with 2.4–3.6 V analog supply, rail-to-rail comparators, PGA-capable op-amps, and FSMC interface for external memory expansion in real-time control systems.

Technical Context

The STM32F303VEH7TR implements a tightly coupled Cortex-M4 core with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time execution of DSP-intensive algorithms such as field-oriented control (FOC) and active filter compensation. Its interconnect matrix enables concurrent peripheral access without bus contention.

Analog subsystem integration includes independent analog supplies (VDDA 2.0–3.6 V, VREFOPAMP 2.4–3.6 V) and dedicated low-noise domains for op-amps and comparators - supporting simultaneous high-speed signal acquisition (ADC conversion time ≤0.20 µs), precision voltage generation (DAC monotonicity ±1 LSB), and fast overvoltage detection (comparator propagation delay <100 ns).

FAQ

What is the maximum operating frequency and core type of the STM32F303VEH7TR?

The STM32F303VEH7TR features an ARM Cortex-M4 core with integrated FPU, running at a maximum frequency of 72 MHz. It delivers 90 DMIPS performance and supports single-cycle multiplication and hardware division. The core includes a Memory Protection Unit (MPU) for enhanced system reliability in real-time applications.

Does the STM32F303VEH7TR support external memory expansion?

Yes, it integrates a Flexible Static Memory Controller (FSMC) supporting NOR, PSRAM, NAND, and PC Card interfaces. The FSMC provides four chip select lines and fully programmable timing parameters - enabling direct connection to external displays, SRAM buffers, or data loggers without external glue logic.

What analog peripherals are integrated into the STM32F303VEH7TR?

The device integrates four rail-to-rail operational amplifiers (configurable as PGAs), seven ultra-fast comparators (<100 ns propagation), two 12-bit DAC channels, and four 12/10/8/6-bit ADCs with up to 40 input channels and 0.20 µs conversion time. All analog blocks feature independent supply domains (VDDA 2.0–3.6 V, VREFOPAMP 2.4–3.6 V) for noise isolation.

Is the STM32F303VEH7TR pin-compatible with other STM32F3 series MCUs?

No - the STM32F303VEH7TR uses the LQFP100 package with 100 pins and specific pin assignments defined in ST's datasheet (DocID026415 Rev 5, Section 4). While other F303 variants (e.g., STM32F303VCT6) share the same package outline, pin functions differ significantly due to peripheral count and routing constraints; direct substitution requires schematic and layout revision.
