Product details
Overview
STM32F303VCY6TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 72 MHz, featuring 256 KB Flash, 48 KB SRAM (including 8 KB CCM), four 12-bit ADCs (0.20 µs conversion), two 12-bit DACs, seven rail-to-rail comparators, and four programmable-gain operational amplifiers - deployed in industrial motor control, digital power supplies, and analog signal conditioning systems.
For engineers reviewing the STM32F303VCY6TR datasheet, STM32F303VCY6TR pinout, STM32F303VCY6TR application, or STM32F303VCY6TR equivalent, key selection criteria include integrated analog front-end capability (PGA + COMP + DAC), CAN 2.0B interface support, capacitive touch sensing (24 channels), and dual-voltage domain operation (VDDA 2.4–3.6 V, VDD 2.0–3.6 V).
Technical Context
This MCU integrates a Cortex-M4 core with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time control with DSP instruction support. Its interconnect matrix decouples peripheral bus arbitration, allowing concurrent high-bandwidth transfers across ADC, DMA, and timers without CPU intervention.
The analog subsystem features independent voltage domains: VDDA powers all analog peripherals (ADC, DAC, COMP, OPAMP) at 2.4–3.6 V, while digital logic runs on VDD (2.0–3.6 V). The four OPAMPs support PGA mode with externally accessible terminals and configurable gain (1–16×), directly interfacing with ADC inputs for sensor signal conditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303RCT6 | LQFP64 package (64-pin), 256 KB Flash, 48 KB SRAM, identical peripheral set but fewer I/Os (51 vs 87) and no TSC support. | Limited analog channel count and no capacitive touch - unsuitable for HMI-rich designs requiring >16 touch inputs. | Select when board space is constrained and full TSC/analog I/O count is unnecessary. |
| STM32G474RET6 | Higher-performance Cortex-M4 (170 MHz), enhanced analog (dual 12-bit ADCs with hardware oversampling), same LQFP64 footprint but different pin mapping. | Superior ADC throughput and resolution - better for high-precision power metering or audio codec interfaces. | Choose for next-gen designs needing >1 MSPS aggregate ADC sampling or improved dynamic range. |
Compared with STM32F303RCT6, the STM32F303VCY6TR offers 36 additional I/Os and full TSC support for complex HMI; versus STM32G474RET6, it trades raw speed for proven analog integration and broader legacy toolchain compatibility in cost-sensitive industrial deployments.

FAQ
What is the maximum operating frequency and core type of the STM32F303VCY6TR?
The STM32F303VCY6TR features an Arm Cortex-M4 core with hardware FPU, rated for a maximum operating frequency of 72 MHz. It delivers 90 DMIPS performance from its CCM SRAM and supports single-cycle multiplication and hardware division. This enables deterministic execution of complex control algorithms such as field-oriented control (FOC) for motors or digital power supply regulation.
Does the STM32F303VCY6TR support capacitive touch sensing, and how many channels are available?
Yes, the STM32F303VCY6TR integrates a dedicated Touch Sensing Controller (TSC) supporting up to 24 capacitive sensing channels. It natively handles touchkey, linear, and rotary touch sensors with built-in charge transfer and spread-spectrum measurement, eliminating the need for external touch controllers. All TSC GPIOs are mapped to specific pins in the LQFP100 package as defined in the device datasheet.
What analog supply voltage ranges are required for the ADC, DAC, and OPAMP peripherals?
The ADC, DAC, comparators, and op-amps require a dedicated analog supply (VDDA) in the range of 2.4 V to 3.6 V. This is distinct from the digital supply (VDD = 2.0–3.6 V). Maintaining VDDA ≥ 2.4 V ensures full 12-bit linearity and specified offset/gain error for all analog peripherals. The datasheet mandates separate filtering and routing for VDDA to preserve SNR in precision measurement applications.
Is the STM32F303VCY6TR pin-compatible with other members of the STM32F303xB/C family?
No - the STM32F303VCY6TR uses the LQFP100 package (100-pin), while other variants like STM32F303CBT6 (LQFP48) or STM32F303RBT6 (LQFP64) have different pin counts and layouts. Pin compatibility exists only within the same package option (e.g., all LQFP100 variants share identical pinouts), but peripheral mapping and alternate functions vary across density grades and memory configurations per the reference manual.
