STMicroelectronics STM32F058T8Y6TR

Overview

STM32F058T8Y6TR from STMicroelectronics is an ARM® Cortex®-M0 32-bit microcontroller with 64 KB Flash, 8 KB SRAM, 48 MHz max CPU frequency, 12-bit ADC (1.0 µs conversion), and 12-bit DAC-designed for embedded control in industrial sensors and low-power HMI systems requiring integrated analog peripherals and capacitive touch sensing.

For engineers reviewing the STM32F058T8Y6TR datasheet, STM32F058T8Y6TR pinout, STM32F058T8Y6TR application, or STM32F058T8Y6TR equivalent, key selection criteria include 1.8 V operation, 5 V-tolerant I/O count (up to 35), RTC with calibration, HDMI CEC interface, and UFBGA64 package compatibility for space-constrained PCB layouts.

Technical Context

The device integrates a single-cycle ARM Cortex-M0 core with hardware parity on SRAM and CRC calculation unit for data integrity. Its clock system combines 4–32 MHz external crystal, 32 kHz RTC oscillator with calibration, and internal 8 MHz RC with x6 PLL-enabling precise timing across sleep/stop modes and real-time control loops.

Analog subsystem includes one 12-bit ADC (0–3.6 V range, 16-channel multiplexing), one 12-bit DAC channel, two programmable analog comparators, and up to 17 capacitive sensing channels-supporting touchkey, linear, and rotary sensor interfaces without external components.

FAQ

What is the maximum operating frequency and supply voltage for STM32F058T8Y6TR?

The STM32F058T8Y6TR operates at up to 48 MHz CPU frequency with digital supply VDD = 1.8 V ± 8%. Analog supply VDDA ranges from 2.4 V to 3.6 V, independent of VDD, ensuring stable ADC/DAC performance across varying system rail conditions.

Does STM32F058T8Y6TR support 5 V tolerant I/Os, and how many?

Yes, STM32F058T8Y6TR supports 5 V tolerant I/Os on up to 35 pins across GPIOA–GPIOF. This capability allows direct interfacing with legacy 5 V peripherals without level shifters, reducing BOM cost and board area in mixed-voltage designs.

What packaging and thermal specifications apply to the UFBGA64 variant?

The STM32F058T8Y6TR uses a 5 × 5 mm UFBGA64 package with 0.5 mm ball pitch and JEDEC-standard thermal resistance (θ_JA = 40 °C/W typical). It is rated for industrial temperature range (–40 °C to +85 °C) and complies with ECOPACK®2 RoHS/REACH requirements.

How does the capacitive sensing controller (TSC) function without external components?

The integrated TSC supports up to 17 channels using internal charge transfer and sigma-delta modulation, eliminating external RC networks. It provides built-in noise immunity, auto-calibration, and direct GPIO mapping-enabling robust touchkey, slider, and rotary implementations with zero external passive components.
