STMicroelectronics STM32F058R8H6TR

Overview

STM32F058R8H6TR from STMicroelectronics is an ARM Cortex-M0 32-bit microcontroller with 64 KB Flash, 8 KB SRAM, 12-bit ADC/DAC, 11 timers (including advanced-control TIM1 with deadtime and emergency stop), dual I²C (one Fast Mode Plus), dual USART (one with ISO7816/LIN/IrDA), dual SPI (one with I²S), HDMI CEC, and capacitive touch sensing - deployed in industrial HMI panels requiring low-voltage operation (1.8 V ±8%) and robust analog integration.

For engineers reviewing the STM32F058R8H6TR datasheet, STM32F058R8H6TR pinout, STM32F058R8H6TR application, or STM32F058R8H6TR equivalent, key selection criteria include 1.8 V core supply tolerance, 54 fast I/Os (35 with 5 V tolerance), RTC with calibration, SWD debug interface, and UFBGA64 package compatibility for space-constrained embedded control designs.

Technical Context

The device implements a single-cycle ARM Cortex-M0 CPU running 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). Its memory subsystem includes 64 KB Flash with ECC-like error detection via CRC unit and 8 KB SRAM with hardware parity checking - enabling deterministic real-time execution in safety-aware applications.

Analog subsystem integration includes one 12-bit, 1.0 µs ADC (0–3.6 V range, 16-channel), one 12-bit DAC channel, two programmable analog comparators, and a dedicated Touch Sensing Controller supporting up to 17 capacitive channels - all sharing a separate VDDA supply (2.4–3.6 V) decoupled from the 1.8 V digital domain.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and core architecture of the STM32F058R8H6TR?

The STM32F058R8H6TR features an ARM Cortex-M0 32-bit RISC core with a maximum CPU frequency of 48 MHz. It executes instructions in single-cycle mode with no pipeline stalls for branches, delivering predictable real-time performance. The core integrates NVIC, SysTick timer, and supports Thumb-2 instruction set for code density efficiency.

Does the STM32F058R8H6TR support 5 V tolerant I/Os, and how many are available?

Yes, the STM32F058R8H6TR supports 5 V tolerant I/Os on up to 35 of its 54 general-purpose pins. This capability is explicitly confirmed in Section 3.7 of the datasheet (DocID023402 Rev 4), allowing direct connection to 5 V logic without external level-shifting circuitry - critical for interoperability with legacy peripherals in industrial systems.

What are the key low-power modes and their typical current consumption values?

The device supports Sleep and Stop low-power modes. In Stop mode with RTC active and VDD = 1.8 V, typical current consumption is 0.8 µA (Table 24, DocID023402 Rev 4). Sleep mode draws ~120 µA at 48 MHz. Wakeup from Stop occurs in ≤5 µs (Table 29), enabling rapid response to external interrupts while maintaining ultra-low quiescent power.

Is the STM32F058R8H6TR pin-compatible with other STM32F058 variants, and what package options exist?

Yes, the STM32F058R8H6TR shares identical pinout and electrical characteristics with other R8 variants in the STM32F058 family (e.g., STM32F058R8T6 in LQFP64). It is offered exclusively in UFBGA64 (5 × 5 mm) per ordering code "H6TR". Other package options for the F058 family include LQFP64, UFQFPN48, and WLCSP36 - but those use different suffixes and are not pin-compatible with H6TR.
