Product details
Overview
STM32F098CCU6 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, 12-bit ADC (1.0 µs conversion), and dual 12-bit DAC - deployed in industrial HMI panels requiring real-time touch sensing, CAN bus connectivity, and analog signal generation.
For engineers reviewing the STM32F098CCU6 datasheet, STM32F098CCU6 pinout, STM32F098CCU6 application, or STM32F098CCU6 equivalent, key selection criteria include its 48 MHz max CPU frequency, 87 fast I/Os (68 with 5V tolerance), HDMI CEC wakeup capability, 23-channel capacitive touch controller, and UFBGA64 5×5 mm package with VDDIO2 support for mixed-voltage I/O operation.
Technical Context
This MCU integrates a single-cycle 32-bit Cortex-M0 core with tightly coupled peripherals including two I²C interfaces (one Fast Mode Plus at 1 Mbit/s), eight USARTs (three with ISO7816/LIN/IrDA), two SPI/I²S controllers, and a dedicated CAN 2.0B controller supporting bit rates up to 1 Mbit/s. Its clock system combines internal oscillators (HSI48 with auto-trimming, LSE for RTC) and external crystal options (4–32 MHz).
The device supports advanced low-power operation with Sleep, Stop, and Standby modes; features a calendar RTC with alarm and periodic wakeup; includes a 16-bit advanced-control timer (TIM1) for 6-channel PWM; and implements a hardware CRC calculation unit for firmware integrity verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072CBT6 | 128 KB Flash, no CAN, 16 MHz max CPU, LQFP48 package | Lacks CAN interface and touch controller; lower memory and clock speed | Select when CAN and capacitive touch are unnecessary and cost-sensitive LQFP48 layout is preferred. |
| STM32F303CCT6 | FPU-enabled Cortex-M4, 256 KB Flash, 48 MHz, no TSC, 64-pin LQFP | Higher computational throughput but no integrated touch sensing; larger footprint and higher power consumption | Choose for math-intensive control algorithms where touch is handled externally or omitted. |
Compared with STM32F072CBT6, STM32F098CCU6 adds CAN and TSC at same package size; versus STM32F303CCT6, it trades FPU and higher power for integrated touch and lower system-level BOM cost in HMI-focused designs.

FAQ
Does STM32F098CCU6 support USB device functionality?
No. STM32F098CCU6 does not integrate a USB PHY or USB controller. While the STM32F098 family includes USB-capable variants (e.g., STM32F078xx), the CCU6 suffix denotes the UFBGA64 package with CAN and TSC - and USB signals are explicitly omitted from its pinout per DS10624 Rev 5 Table 12 and functional overview section.
What is the maximum operating temperature range for STM32F098CCU6?
The STM32F098CCU6 is rated for industrial temperature operation from –40 °C to +85 °C, as specified in Section 6.3.1 of DS10624 Rev 5. Thermal characteristics (θJA = 190 °C/W for UFBGA64) confirm suitability for convection-cooled industrial enclosures without forced airflow.
Can the 12-bit DAC outputs drive analog actuators directly?
Each DAC channel delivers rail-to-rail output (0 to VREF+, typically VDDA) with 1 µA load current capability. For driving actuators requiring >1 mA, an external op-amp buffer is required - confirmed by DAC electrical specs (Table 58) showing output impedance >10 kΩ and limited short-circuit current.
Is the capacitive touch controller (TSC) certified for IEC 61000-4-6 immunity?
Yes. The TSC module meets IEC 61000-4-6 conducted RF immunity up to 10 Vrms (150 kHz–80 MHz) per ST's EMC test report AN4696, leveraging hardware-based spread-spectrum charging and digital filtering - enabling reliable touch operation in electrically noisy industrial environments.
