STMicroelectronics STM32F058R8H7

Overview

STM32F058R8H7 from STMicroelectronics is an ARM® Cortex®-M0 32-bit microcontroller with 64 KB Flash, 8 KB SRAM (with hardware parity), and integrated analog peripherals including a 12-bit ADC (1.0 µs conversion), 12-bit DAC, two analog comparators, and up to 17 capacitive sensing channels - deployed in industrial HMI touch panels requiring low-voltage operation (1.8 V ±8%) and RTC-backed periodic wake-up from Stop mode.

For engineers reviewing the STM32F058R8H7 datasheet, STM32F058R8H7 pinout, STM32F058R8H7 application, or STM32F058R8H7 equivalent, key selection criteria include its 1.8 V core supply tolerance, UFBGA64 5×5 mm package with 54 fast I/Os (35 5 V-tolerant), dual USARTs with IrDA/LIN/ISO7816 support, and HDMI CEC interface for consumer electronics control integration.

Technical Context

The STM32F058R8H7 implements a single-cycle ARM Cortex-M0 core running at up to 48 MHz, supported by an integrated 8 MHz RC oscillator with x6 PLL and dual clock sources (4–32 MHz HSE, 32 kHz LSE) enabling precise RTC calibration and low-jitter system timing. Its memory subsystem includes 64 KB Flash with error correction and 8 KB SRAM with hardware parity checking for safety-critical data retention.

Peripheral architecture features a 5-channel DMA controller, 11 timers (including TIM1 advanced-control timer with deadtime generation and emergency stop), two I²C interfaces (one Fast Mode Plus), two SPIs (18 Mbit/s), and dedicated TSC hardware for capacitive touch - all operating under unified power management with Sleep, Stop, and VBAT-RTC backup modes.

FAQ

What is the maximum operating frequency and core type of the STM32F058R8H7?

The STM32F058R8H7 features an ARM Cortex-M0 32-bit RISC core with a maximum operating frequency of 48 MHz. It achieves this speed using the internal 8 MHz RC oscillator with x6 PLL or an external 4–32 MHz crystal. The core supports Thumb-2 instruction set and delivers 1.25 DMIPS/MHz performance, validated across the full industrial temperature range (–40°C to +85°C).

Does the STM32F058R8H7 support 5 V tolerant I/Os, and how many are available?

Yes, the STM32F058R8H7 supports 5 V tolerant I/Os on up to 35 pins (including PA0–PA15, PB0–PB15, and PC13–PC15). These pins tolerate 5 V inputs while operating from a 1.8 V supply, eliminating the need for external level translators when interfacing with legacy 5 V peripherals such as encoders, optocouplers, or industrial sensors.

What analog peripherals are integrated into the STM32F058R8H7?

The STM32F058R8H7 integrates a 12-bit, 1.0 µs ADC with up to 16 channels and 0–3.6 V input range; a 12-bit DAC with buffered output; two fast low-power analog comparators with programmable hysteresis and output routing; and a dedicated Touch Sensing Controller (TSC) supporting up to 17 capacitive sensing channels for touchkey, linear, and rotary sensors.

Which communication interfaces does the STM32F058R8H7 provide, and what are their key capabilities?

The STM32F058R8H7 provides two I²C interfaces (one supporting Fast Mode Plus at 1 Mbit/s with extra current sink), two USARTs (one with ISO7816, IrDA, LIN, and auto-baud detection), two SPIs (18 Mbit/s, one multiplexed with I²S), and a dedicated HDMI CEC interface with header wakeup. All interfaces support low-power mode operation and retain functionality during Stop mode.
