STMicroelectronics STM32F098CCU6TR

Overview

STM32F098CCU6TR from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM (with hardware parity), integrated CAN 2.0B interface, and dual 12-bit DAC channels - deployed in industrial HMI touch panels requiring real-time capacitive sensing, CAN bus connectivity, and analog output control.

For engineers reviewing the STM32F098CCU6TR datasheet, STM32F098CCU6TR pinout, STM32F098CCU6TR application, or STM32F098CCU6TR equivalent, key selection criteria include its 48 MHz max CPU frequency, 1.8 V core supply tolerance, 87 fast I/Os (68 with 5V-tolerance), HDMI CEC wakeup capability, and UFBGA64 package compatibility with high-density PCB layouts.

Technical Context

This MCU integrates a single-cycle 32-bit Cortex-M0 core with deterministic interrupt latency and supports full ARM Thumb®-2 instruction set. Its clock system combines internal oscillators (HSI48 with auto-trimming, LSI, LSE) and external crystal options (4–32 MHz HSE, 32 kHz RTC), enabling precise timing for CAN bit-rate synchronization and real-time touch sensing.

The peripheral architecture features a 12-channel DMA controller tightly coupled to dual ADC/DAC paths, advanced TIM1 (6-channel PWM), and dedicated TSC block supporting up to 23 capacitive sensing channels - all coordinated via nested vectored interrupt controller (NVIC) with 32 interrupt lines and priority grouping.

Key Specifications

Pinout & Package

STM32F098CCU6TR uses the UFBGA64 package (5 × 5 mm, 0.5 mm ball pitch, ECOPACK2-compliant). It features 64 solder balls arranged in 8×8 grid with corner balls omitted (A1, A8, H1, H8 missing), optimized for automated assembly and thermal dissipation in industrial ambient conditions.

FAQ

What is the maximum operating frequency and core voltage specification for STM32F098CCU6TR?

The STM32F098CCU6TR operates at up to 48 MHz using the Cortex-M0 core, with a core supply voltage (VDD) range of 1.8 V ± 8% (1.656 V to 1.944 V). This narrow tolerance requires tight regulation but enables ultra-low-power operation in battery-backed or energy-harvesting systems.

Does STM32F098CCU6TR support USB functionality?

No, STM32F098CCU6TR does not include USB PHY or USB device controller logic. Although pins PA11/PA12 are physically present in the UFBGA64 package, they are unconnected internally and function solely as general-purpose I/Os - unlike USB-capable variants such as STM32F072 or STM32F042.

How many capacitive sensing channels does the TSC support, and what GPIOs are assigned?

The integrated Touch Sensing Controller (TSC) supports up to 23 capacitive sensing channels, mapped across GPIOs PA0–PA7, PB0–PB13, PC0–PC4, and PF0–PF1. Channel assignment is configurable via TSC registers, and hardware-accelerated acquisition enables sub-10 µs per-channel measurement with built-in noise filtering.

What is the purpose of the HDMI CEC wakeup feature, and how is it implemented?

The HDMI CEC wakeup feature allows the MCU to remain in Stop mode while monitoring CEC bus activity; a valid CEC header triggers hardware wakeup within 2.5 µs. It uses dedicated logic tied to PB10 (CEC pin), independent of CPU clocks, enabling zero-power remote control reception in consumer electronics and smart home hubs.
