Product details
Overview
STM32F078VBH6TR from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 128 KB Flash, 16 KB SRAM, crystal-less USB 2.0 FS interface, 12-bit dual DAC, and 12-bit ADC-designed for embedded control systems requiring precise analog signal generation and low-power USB connectivity in industrial HMI and sensor gateway applications.
For engineers reviewing the STM32F078VBH6TR datasheet, STM32F078VBH6TR pinout, STM32F078VBH6TR application, or STM32F078VBH6TR equivalent, key selection criteria include USB clocking autonomy (48 MHz internal oscillator with trimming), VDDIO2 support for mixed-voltage I/O (1.65–3.6 V), 5V-tolerant GPIO count (up to 67), and capacitive touch sensing capability (23 channels).
Technical Context
The device integrates a 48 MHz Arm Cortex-M0 core with hardware CRC, memory protection unit (MPU), and nested vectored interrupt controller (NVIC) supporting up to 32 external interrupts. Its clock system combines internal oscillators-including a factory-trimmed 48 MHz HSI48 for USB-with external 4–32 MHz HSE and 32 kHz LSE for RTC calibration.
Analog subsystems include two independent 12-bit DACs with configurable output buffers, a 12-bit 1.0 µs ADC with 16-channel multiplexing and separate VDDA supply (2.4–3.6 V), and two fast comparators with programmable hysteresis and window mode-enabling closed-loop analog control without external components.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072VBH6 | No crystal-less USB; requires external 48 MHz crystal or HSE for USB FS; same Flash/SRAM, DAC/ADC specs | Lacks HSI48 oscillator and USB clock recovery system - unsuitable for space-constrained or battery-powered USB devices | Select when board layout accommodates 48 MHz crystal and cost sensitivity outweighs BOM simplification |
| STM32F091VCJ6 | 256 KB Flash, 32 KB SRAM, adds CAN 2.0B interface; same USB/DAC/ADC capabilities and 100-pin UFBGA | Supports automotive diagnostics and industrial fieldbus integration where CAN is mandatory | Choose when future-proofing for CAN-based firmware updates or distributed control networks is required |
Compared with STM32F072VBH6, STM32F078VBH6TR reduces component count via crystal-less USB and improves analog subsystem flexibility with independent VDDIO2; versus STM32F091VCJ6, it trades CAN and extra memory for lower unit cost and identical footprint compatibility in non-CAN applications.

FAQ
Does STM32F078VBH6TR support USB device enumeration without an external crystal?
Yes. It integrates a factory-trimmed 48 MHz HSI48 oscillator with automatic frequency calibration using USB Start-of-Frame (SOF) tokens. This enables full-speed USB 2.0 device enumeration and data transfer without any external crystal or oscillator, reducing BOM cost and PCB area.
What is the maximum number of 5V-tolerant I/Os on STM32F078VBH6TR?
The device supports up to 67 5V-tolerant I/Os across GPIO ports A–F. These pins maintain logic-level compatibility with 5V peripherals while operating from a 1.8 V or 3.3 V VDD supply, eliminating the need for external level translators in mixed-voltage systems.
Can the two DAC channels operate simultaneously with independent output buffers?
Yes. Both 12-bit DAC channels (DAC1 and DAC2) feature dedicated output buffers that can be enabled independently. They support simultaneous waveform generation with programmable trigger sources (timers, software, or external events), enabling dual-tone audio synthesis or differential analog output.
Is the capacitive touch sensing controller (TSC) capable of handling noisy industrial environments?
Yes. The TSC includes hardware-accelerated acquisition, spread-spectrum charging, and built-in digital filtering to reject 50/60 Hz mains noise and EFT bursts. With up to 23 channels and configurable charge transfer cycles, it achieves reliable touch detection even in electrically harsh settings like factory floor HMIs.
