STMicroelectronics STM32F373CCT6TR

Overview

STM32F373CCT6TR from STMicroelectronics is a 32-bit ARM® Cortex®-M4 microcontroller with FPU and MPU, operating up to 72 MHz, featuring 256 KB Flash, 32 KB SRAM, four 12-/16-bit ADCs (including three sigma-delta), three 12-bit DACs, two rail-to-rail comparators, and integrated capacitive sensing-designed for precision analog signal acquisition in industrial sensor nodes and motor control feedback systems.

For engineers reviewing the STM32F373CCT6TR datasheet, STM32F373CCT6TR pinout, STM32F373CCT6TR application, or STM32F373CCT6TR equivalent, key selection criteria include its dual ADC architecture (12-bit SAR + 16-bit SDADC), 5 V-tolerant I/O capability on 45 pins, CAN 2.0B interface, USB 2.0 full-speed support, and RTC with periodic wakeup from Stop/Standby modes.

Technical Context

The device integrates a single-core Cortex-M4 with hardware floating-point unit and memory protection unit, enabling deterministic real-time control with DSP extensions for filtering and sensor fusion. Its analog subsystem combines high-resolution sigma-delta converters (21 single-ended/11 differential channels) with dedicated 12-bit SAR ADC (16-channel, 1 µs conversion), each with independent analog supply domains (2.2–3.6 V and 2.4–3.6 V).

Clock management includes dual oscillators (4–32 MHz HSE and 32 kHz LSE), internal RC sources (8 MHz HSI, 40 kHz LSI), and a programmable PLL supporting multiple peripheral clock trees. Power management supports Sleep, Stop, and Standby modes with VBAT backup for RTC and registers, plus programmable voltage detector (PVD) for brown-out monitoring.

FAQ

What is the maximum operating frequency and core type of the STM32F373CCT6TR?

The STM32F373CCT6TR features an ARM Cortex-M4 core with hardware FPU and MPU, operating at up to 72 MHz. It delivers 1.25 DMIPS/MHz (Dhrystone 2.1) and supports single-cycle multiplication and hardware division-enabling deterministic execution of control loops and DSP routines without software emulation overhead.

Does the STM32F373CCT6TR support 5 V tolerant I/Os, and how many?

Yes, the STM32F373CCT6TR supports 5 V tolerant I/Os on up to 45 pins across GPIO ports A, B, C, D, E, and F. This capability allows direct interfacing with 5 V logic families and industrial sensors without external level-shifting circuitry, reducing BOM cost and PCB complexity in mixed-voltage systems.

What analog peripherals are integrated, and what are their key resolution and channel counts?

The device integrates one 12-bit SAR ADC (16 channels, 1 µs conversion), three 16-bit sigma-delta ADCs (up to 21 single-ended or 11 differential channels), three 12-bit DACs, and two rail-to-rail comparators. Each ADC has dedicated analog supply domains (VDDA: 2.2–3.6 V for SDADC; 2.4–3.6 V for SAR), ensuring optimal SNR and dynamic range.

Is the STM32F373CCT6TR pin-compatible with other STM32F3 devices, and which packages share the same footprint?

The STM32F373CCT6TR uses the LQFP64 (10 × 10 mm) package and is pin-compatible with other STM32F373xx variants in the same package, such as STM32F373CBT6 and STM32F373RBT6. It is not pin-compatible with LQFP48, LQFP100, or UFBGA100 variants due to differing pin counts and layouts.
