STMicroelectronics STM32F378VCH6

Overview

STM32F378VCH6 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 with hardware parity, three 12-bit DACs, four ADCs (including three 16-bit sigma-delta), two rail-to-rail comparators, and integrated CAN 2.0B interface - deployed in industrial sensor signal conditioning and precision analog front-end control systems.

For engineers reviewing the STM32F378VCH6 datasheet, STM32F378VCH6 pinout, STM32F378VCH6 application, or STM32F378VCH6 equivalent, key selection considerations include its dual ADC architecture (12-bit SAR + 16-bit SDADC), 1.8 V core supply tolerance, 24-channel capacitive sensing capability, and UFBGA100 package compatibility with high-density PCB layouts.

Technical Context

The STM32F378VCH6 integrates a single-core Cortex-M4 CPU with hardware floating-point unit and memory protection unit, supporting deterministic real-time execution of mixed-signal control algorithms. Its analog subsystem combines a 12-bit 1 µs SAR ADC (16 channels) with three independent 16-bit sigma-delta ADCs (up to 21 single-ended inputs), each with dedicated 2.2–3.6 V analog supplies and programmable gain.

Clock management includes dual oscillators (4–32 MHz HSE and 32 kHz LSE), internal 8 MHz RC with x16 PLL, and 40 kHz LSI - enabling precise RTC calibration and low-power Stop-mode wakeup. Communication peripherals include CAN 2.0B, three USARTs with LIN/IrDA support, two Fast Mode Plus I²Cs, and three SPIs with I²S multiplexing.

Key Specifications

Pinout & Package

STM32F378VCH6 uses the UFBGA100 package: 100-ball ultra-fine-pitch ball grid array, 7 × 7 mm body, 0.5 mm pitch, with exposed thermal pad. Pin functions follow ST's standard STM32F3 series mapping, including dedicated VREF+, VREF-, VSSA/VDDA, and SDADC-specific analog input banks.

FAQ

What is the maximum operating frequency and core voltage range for STM32F378VCH6?

The STM32F378VCH6 operates at up to 72 MHz using the ARM Cortex-M4 core, with a core supply voltage (VDD) range of 1.8 V ±8% (1.656 V to 1.944 V). The analog supply (VDDA) supports 1.65–3.6 V, enabling flexible interfacing with external sensors and references while maintaining ADC/DAC linearity and comparator response.

Does STM32F378VCH6 support hardware-accelerated cryptography or secure boot?

No, the STM32F378VCH6 does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot features. It lacks a TRNG, memory firewall, or embedded secure ROM. Security relies on software-implemented protocols and external secure elements - consistent with its positioning as an analog-optimized general-purpose MCU rather than a secure microcontroller.

Can the three 16-bit sigma-delta ADCs operate simultaneously with independent sampling clocks?

Yes, all three SDADCs (SDADC1–SDADC3) can operate concurrently with independent trigger sources (software, timer, or external event), configurable conversion rates from 10 SPS to 1 MSPS, and individual oversampling ratios up to 1024×. This enables true simultaneous multi-channel high-resolution acquisition - confirmed in Section 3.13 of DocID025608 Rev 4.

Is the UFBGA100 package of STM32F378VCH6 RoHS-compliant and lead-free?

Yes, the STM32F378VCH6 in UFBGA100 packaging is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. Full compliance documentation, including material declarations and test reports, is available via ST's Quality & Reliability portal under part number STM32F378VCH6.
