STMicroelectronics STM32F058R8H6

Overview

STM32F058R8H6 from STMicroelectronics is an ARM® Cortex®-M0 32-bit microcontroller with 64 KB Flash, 8 KB SRAM, 12-bit ADC and DAC, HDMI CEC interface, and 54 fast I/Os - including 35 with 5 V tolerance - designed for cost-sensitive industrial control and capacitive touch HMI applications operating at 1.8 V supply.

For engineers reviewing the STM32F058R8H6 datasheet, STM32F058R8H6 pinout, STM32F058R8H6 application, or STM32F058R8H6 equivalent, key selection criteria include 1.8 V core operation, integrated touch sensing controller (up to 17 channels), dual USARTs with IrDA/LIN support, and UFBGA64 package compatibility with space-constrained PCB layouts.

Technical Context

The STM32F058R8H6 integrates a single-cycle ARM Cortex-M0 core running up to 48 MHz, supported by an internal 8 MHz RC oscillator with x6 PLL and dedicated 32 kHz RTC crystal input. Its clock tree enables precise timing for real-time control and low-power wake-up sequences.

It features a 12-bit, 1.0 µs ADC with 16-channel multiplexing and separate analog supply (2.4–3.6 V), plus one 12-bit DAC channel driven by TIM6, two programmable analog comparators, and a dedicated touch sensing controller (TSC) supporting linear/rotary sensors and touchkeys without external components.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and supply voltage for STM32F058R8H6?

The STM32F058R8H6 operates at up to 48 MHz using its internal 8 MHz RC oscillator with PLL, or external crystals up to 32 MHz. Its digital core requires VDD = 1.8 V ± 8% (1.656–1.944 V); analog supply VDDA ranges from 2.4 V to 3.6 V, enabling high-precision ADC/DAC operation independent of core voltage.

Does STM32F058R8H6 support hardware touch sensing without external components?

Yes - it integrates a dedicated Touch Sensing Controller (TSC) with 17 capacitive sensing channels, supporting self-capacitive touchkey, linear slider, and rotary encoder configurations. The TSC performs charge-transfer measurement in hardware, eliminating external RC networks and reducing firmware load versus software-based solutions.

Can STM32F058R8H6 generate PWM signals with deadtime for motor control?

Yes - the advanced-control timer (TIM1) provides 16-bit resolution, 7-channel complementary PWM output, programmable deadtime insertion (down to 1 ns step), and emergency stop functionality triggered by external fault inputs. This enables safe 3-phase inverter gate driving with hardware-level protection.

Is the UFBGA64 package of STM32F058R8H6 compatible with standard reflow profiles?

Yes - the UFBGA64 (5 × 5 mm, 0.5 mm pitch) package complies with JEDEC J-STD-020 moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak temperature ≤ 260 °C). ST provides recommended PCB pad layout and stencil design rules in DocID023402 Section 7.1.
