STMicroelectronics STM32F302CCT6

Overview

STM32F302CCT6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 72 MHz, featuring 256 KB Flash, 40 KB SRAM (16 KB with hardware parity), dual 12-bit ADCs (0.20 µs conversion, 17-channel), one 12-bit DAC, four rail-to-rail comparators, and two programmable-gain operational amplifiers - deployed in motor control, analog signal acquisition, and industrial sensor interface systems.

For engineers reviewing the STM32F302CCT6 datasheet, STM32F302CCT6 pinout, STM32F302CCT6 application, or STM32F302CCT6 equivalent, key selection criteria include integrated analog front-end capability (PGA + COMP + DAC), CAN 2.0B support, capacitive touch sensing (24 channels), and LQFP64 package compatibility with legacy STM32F303/301 footprint constraints.

Technical Context

The STM32F302CCT6 integrates a Cortex-M4 core with single-cycle multiply, hardware divide, DSP extensions, and MPU for deterministic real-time execution. Its analog subsystem includes two independent ADCs with selectable 6/8/10/12-bit resolution, differential input support, and dedicated 2–3.6 V analog supply domain.

Timing architecture combines one 32-bit general-purpose timer, two 16-bit timers with quadrature encoder input, one advanced-control timer (6-channel PWM + deadtime + emergency stop), and RTC with calendar alarm - all synchronized via a multi-source clock tree including HSE (4–32 MHz), LSE (32.768 kHz), and internal RC oscillators.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with STM32F303CCT6, the STM32F302CCT6 omits the sigma-delta ADC but retains identical timing, communication, and analog peripheral capabilities - making it optimal for cost-constrained motor control where 12-bit SAR ADC suffices. Versus STM32F072CBT6, it delivers significantly higher computational throughput and integrated analog front-end density, justifying its use in closed-loop servo and multi-sensor systems.

FAQ

What is the maximum operating frequency and core type of the STM32F302CCT6?

The STM32F302CCT6 features an Arm Cortex-M4 core with integrated FPU, capable of running at up to 72 MHz. It supports single-cycle multiplication, hardware division, and DSP instructions - enabling efficient execution of motor control algorithms and real-time signal processing without external accelerators.

Does the STM32F302CCT6 support hardware CRC calculation and memory protection?

Yes, it includes a dedicated CRC calculation unit compliant with IEEE 802.3 and a Memory Protection Unit (MPU) that enforces privilege levels and region-based access control - essential for functional safety certification (e.g., IEC 61508 SIL2) and secure firmware partitioning in industrial applications.

What analog peripherals are integrated and how are they powered?

The device integrates dual 12-bit ADCs (17-channel, 0.20 µs), one 12-bit DAC, four rail-to-rail comparators, and two programmable-gain op-amps. All analog peripherals use separate analog supplies: VDDA (2.0–3.6 V) and dedicated VREF+ (2.4–3.6 V for DAC/OPAMP), minimizing digital noise coupling into sensitive analog paths.

Is the STM32F302CCT6 pin-compatible with other STM32F3 packages?

No - the STM32F302CCT6 uses LQFP64 (10 × 10 mm). While functionally similar to STM32F303CCT6 (same package), it is not pin-compatible with LQFP48 or LQFP100 variants of the same family due to differing pin counts and peripheral mappings - PCB layout must match the 64-pin footprint exactly.
