Product details
Overview
STM32F098VCH6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM (HW parity), integrated CAN 2.0B interface, 12-bit dual-channel DAC, and 12-bit 1.0 µs ADC - designed for industrial HMI, smart sensor nodes, and CAN-based embedded control systems operating at 1.8 V supply.
For engineers reviewing the STM32F098VCH6 datasheet, STM32F098VCH6 pinout, STM32F098VCH6 application, or STM32F098VCH6 equivalent, key selection criteria include its 48 MHz max CPU frequency, 87 fast I/Os (68 with 5V tolerance), HDMI CEC wakeup capability, 32 kHz RTC oscillator with calibration, and UFBGA100 package with 0.5 mm pitch for high-density PCB layouts.
Technical Context
This MCU integrates a single-cycle ARM Cortex-M0 core with tightly coupled NVIC, CRC calculation unit, and clock recovery system (CRS) for USB/CEC synchronization. It supports dual-supply operation: digital I/Os at 1.8 V ±8% and analog domain (VDDA) up to 3.6 V, enabling mixed-signal coexistence in low-power industrial gateways.
The peripheral set includes two I²C interfaces (one Fast Mode Plus), eight USARTs (three with ISO7816/LIN/IrDA), two SPI/I²S controllers, one advanced-control timer (TIM1) for 6-channel PWM, and a touch sensing controller (TSC) supporting up to 23 capacitive channels - all coordinated via a 12-channel DMA controller and shared memory-mapped registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables real-time deterministic control loops with <200 ns interrupt latency. |
| Memory | 256 KB Flash + 32 KB SRAM with hardware parity - supports secure firmware updates and fault-tolerant data logging. |
| Analog Peripherals | 12-bit ADC (1.0 µs conversion, 16 ch), 12-bit dual DAC, 2 comparators - suitable for closed-loop analog actuation and sensor signal conditioning. |
| Communication | CAN 2.0B, 2×I²C (Fast Mode Plus), 8×USART (3×ISO7816), 2×SPI/I²S - meets automotive diagnostics, industrial fieldbus, and audio subsystem requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072VBT6 | No CAN interface; 128 KB Flash; same UFBGA100 package and 48 MHz Cortex-M0 core. | Lacks CAN 2.0B support - unsuitable for automotive or industrial fieldbus nodes requiring native CAN PHY. | Select when CAN is unnecessary and cost reduction is prioritized over fieldbus compatibility. |
| STM32G071VBT6 | Newer G0-series; 128 KB Flash; no TSC or HDMI CEC; enhanced USB 2.0 FS support. | Missing capacitive touch controller and CEC wakeup - not viable for touch-enabled consumer gateways or CEC-linked appliances. | Choose for USB-centric designs where modern peripherals (USB PD, AES) outweigh legacy feature retention. |
Compared with STM32F072VBT6 and STM32G071VBT6, the STM32F098VCH6 uniquely combines CAN 2.0B, HDMI CEC wakeup, and 23-channel TSC in a 1.8 V UFBGA100 package - making it irreplaceable for cost-constrained, mixed-signal, fieldbus-connected edge nodes requiring both robust communication and human interface integration.

FAQ
What is the maximum operating frequency and voltage range for STM32F098VCH6?
The STM32F098VCH6 operates at up to 48 MHz CPU frequency with a digital supply voltage of 1.8 V ±8% (1.656 V to 1.944 V). The analog supply (VDDA) supports 1.8 V to 3.6 V, and selected I/Os accept VDDIO2 from 1.65 V to 3.6 V - enabling flexible mixed-voltage system design while maintaining full peripheral functionality.
Does STM32F098VCH6 support USB connectivity?
No, the STM32F098VCH6 does not include a USB interface. It features CAN 2.0B, multiple USARTs (including ISO7816 and LIN), I²C, SPI/I²S, and HDMI CEC - but lacks USB PHY or USB device controller. For USB-enabled designs, ST recommends the STM32F072 or STM32G071 families.
How many capacitive sensing channels does the TSC support, and what is their resolution?
The Touch Sensing Controller (TSC) supports up to 23 capacitive sensing channels with 16-bit counter resolution and built-in spread-spectrum modulation. It delivers >100:1 dynamic range and supports touchkey, linear slider, and rotary encoder topologies - validated per IEC 61000-4-6 for EMC robustness in industrial environments.
What debug interfaces are available on STM32F098VCH6?
The STM32F098VCH6 supports Serial Wire Debug (SWD) via dedicated PA13 (SWDIO) and PA14 (SWCLK) pins. It does not support JTAG. SWD enables full programming, real-time debugging, and trace capabilities using standard ST-LINK/V2 or compatible debug probes - with minimal pin overhead and no impact on GPIO count.
