STMicroelectronics STM32F302RCT7TR

Overview

STM32F302RCT7TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 72 MHz, featuring 256 KB Flash, 40 KB SRAM (16 KB with HW parity), dual 12-bit ADCs (0.20 µs conversion, 17-channel), one 12-bit DAC, four rail-to-rail comparators, two programmable-gain operational amplifiers, and CAN 2.0B interface - deployed in motor control, digital power supplies, and industrial sensor fusion systems.

For engineers reviewing the STM32F302RCT7TR datasheet, STM32F302RCT7TR pinout, STM32F302RCT7TR application, or STM32F302RCT7TR equivalent, key selection criteria include analog peripheral integration (PGA + COMP + DAC), 5 V-tolerant I/O count (up to 87), USB 2.0 FS + CAN coexistence, and LQFP64 package compatibility with legacy STM32F303 designs.

Technical Context

The device implements a tightly coupled Cortex-M4 core with single-cycle MAC, hardware divide, and DSP extensions, paired with an MPU for memory protection. Its analog subsystem integrates two independent OPAMPs configurable as PGAs with external feedback, four fast comparators with window mode, and dual ADCs sharing a common analog domain but supporting simultaneous sampling.

Clock architecture includes dual oscillators (4–32 MHz HSE + 32.768 kHz LSE), internal 8 MHz HSI with PLL multiplication, and 40 kHz LSI - enabling precise RTC calibration and low-power Stop/Standby wake-up via multiple sources including comparator output and TSC events.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32F302RCT7TR operates at up to 72 MHz with a core supply (VDD) and analog supply (VDDA) range of 2.0 V to 3.6 V. The VDDA must be ≥ VDD for guaranteed analog performance, and the device supports brown-out detection and programmable voltage monitoring down to 2.0 V threshold.

Does this MCU support hardware cryptographic acceleration?

No, the STM32F302RCT7TR does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption; for hardware crypto, consider STM32L4 or STM32H7 series devices with CryptoCell or AES peripherals.

Can the internal OPAMPs be used without external components?

Yes - both OPAMPs support unity-gain buffer mode using internal feedback, and PGA mode with external resistors for gains from 1× to 100×. All terminals (VIN+, VIN−, VOUT) are accessible on dedicated pins, enabling flexible configuration without additional opamp ICs.

Is the USB interface full-speed capable without external PHY components?

Yes, the STM32F302RCT7TR integrates a full-speed USB 2.0 PHY with internal pull-up resistors on PA11/PA12. No external transceiver or termination resistors are required - only a USB connector and ESD protection diodes are needed for basic compliance.
