Product details
Overview
STM32F098VCH6TR from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM, integrated CAN 2.0B interface, dual 12-bit DAC, and 12-bit ADC-designed for industrial HMI, smart sensor nodes, and CAN-based embedded control systems operating at 1.8 V supply.
For engineers reviewing the STM32F098VCH6TR datasheet, STM32F098VCH6TR pinout, STM32F098VCH6TR application, or STM32F098VCH6TR equivalent, key selection criteria include CAN timing compliance, 1.8 V I/O tolerance, capacitive touch channel count (23), RTC alarm + wakeup capability, and UFBGA100 package thermal performance in compact industrial enclosures.
Technical Context
This MCU integrates a 48 MHz Cortex-M0 core with hardware CRC, memory protection unit (MPU), and clock recovery system (CRS) for USB/CAN synchronization. It supports dual-bank Flash for secure firmware updates and includes dedicated TSC peripheral with spread-spectrum modulation for robust capacitive sensing.
The analog subsystem features independent VDDA supply (2.4–3.6 V), internal voltage reference (VREFINT), temperature sensor, and battery voltage monitoring (VBAT). Its CAN controller complies with ISO 11898-1:2015 and supports programmable bit timing, loopback mode, and automatic retransmission.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, up to 48 MHz - enables real-time deterministic control with <20 ns interrupt latency. |
| Memory | 256 KB Flash + 32 KB SRAM with HW parity - supports secure boot, OTA updates, and ECC-protected data buffers. |
| Analog Peripherals | 1× 12-bit ADC (16 ch, 1 µs), 2× 12-bit DAC, 2× comparators - enables closed-loop analog control without external signal chain components. |
| Communication | CAN 2.0B, 2× I²C (Fast Mode Plus), 8× USART (3 with ISO7816), 2× SPI/I²S - meets automotive diagnostics (UDS over CAN), industrial serial protocols, and audio interface needs. |

| Capacitive Sensing | 23-channel TSC with shield electrode support - enables robust touchkey, slider, and rotary encoder implementation in noisy industrial environments. |
| Supply & Power | VDD = 1.8 V ±8%, VDDA = 2.4–3.6 V, Stop mode current <1.3 µA - allows direct integration with low-voltage battery or energy-harvesting power rails. |
Pinout & Package
STM32F098VCH6TR uses a 100-pin UFBGA package (7 × 7 mm, 0.5 mm pitch) with 87 fast I/Os - 68 of which are 5 V-tolerant and 19 support independent VDDIO2 supply (1.65–3.6 V).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power and ground domains | Separate digital/analog supplies enable noise isolation; VDDA must be ≥ VDD for ADC/DAC accuracy. |
| PA13/PA14 (SWDIO/SWCLK) | Serial Wire Debug interface | Enables non-intrusive debug and programming without dedicated JTAG pins; shares GPIO functionality. |
| PD0/PD1 (CAN_RX/CAN_TX) | CAN physical layer interface | Direct connection to CAN transceiver; requires external 120 Ω termination and ESD protection per ISO 11898-2. |
| PC13/PC14/PC15 | RTC oscillator inputs | Support 32.768 kHz crystal; PC14/PC15 require load capacitance matching (12.5 pF typical) for ±20 ppm accuracy. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/Os | All support external interrupt; up to 68 pins tolerate 5 V input while powered at 1.8 V - simplifies level-shifting in mixed-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| HDMI CEC wakeup | Enables low-power standby with header-triggered wake from Stop mode - critical for consumer electronics remote control integration. |
| Internal 48 MHz oscillator with auto-trimming | Eliminates external crystal for USB/CAN clocking; calibrated against external sync signal to maintain ±0.25% accuracy over temperature. |
| 96-bit unique ID | Provides immutable device identity for secure firmware binding, license enforcement, and anti-cloning in OEM deployments. |
| ECOPACK2-compliant packaging | Meets RoHS, halogen-free, and lead-free requirements per EU Directive 2011/65/EU - ensures compliance for global industrial shipments. |
| Independent VDDIO2 supply | Allows 19 I/Os to operate at 1.65–3.6 V while core runs at 1.8 V - supports interfacing with legacy 3.3 V peripherals without level shifters. |

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 | Suitable for USB-only or I²C/SPI-based control where CAN is not required | Select when CAN is unnecessary and lower BOM cost is prioritized over fieldbus compatibility. |
| STM32G071VBT6 | Cortex-M0+ core; 128 KB Flash; no TSC; 1× DAC; CAN FD capable | Better USB 2.0 FS support and higher crypto acceleration, but lacks capacitive sensing and second DAC channel | Choose for USB-CDC or secure bootloader applications where CAN FD and AES-128 outweigh touch and dual-DAC needs. |
Compared with STM32F072VBT6 and STM32G071VBT6, the STM32F098VCH6TR uniquely combines CAN 2.0B, dual 12-bit DAC, 23-channel TSC, and 1.8 V operation - making it the only option among the three for compact, low-voltage, touch-enabled CAN edge nodes requiring analog output fidelity and RTC-backed scheduling.

FAQ
What is the maximum allowed VDDA voltage relative to VDD?
VDDA must be within the range of VDD to 3.6 V, and cannot be lower than VDD. Operating VDDA < VDD risks ADC/DAC conversion errors and may cause analog peripheral malfunction. The datasheet specifies VDDA ≥ VDD as a hard requirement for guaranteed specification compliance.
Does STM32F098VCH6TR support USB device functionality?
No - this part lacks a USB PHY and dedicated USB interface. While it includes an internal 48 MHz oscillator suitable for USB clocking, there is no USB peripheral block, registers, or pin assignments for D+/D− lines. USB capability is present only in STM32F04x/F07x/F09x derivatives with 'U' or 'Z' in the part number suffix.
Can the 23 capacitive sensing channels operate simultaneously?
Yes - all 23 TSC channels can be scanned in sequence within a single acquisition cycle. The TSC supports hardware-accelerated charge transfer with automatic gain control and spread-spectrum modulation, enabling full-channel scan times under 10 ms at default settings - sufficient for real-time touch UI response.
Is the CAN interface compatible with ISO 11898-2 physical layer?
Yes - the CAN controller implements ISO 11898-1:2015 data link layer and is fully compatible with standard ISO 11898-2 transceivers (e.g., TJA1042, SN65HVD230). It supports dominant/recessive bit encoding, error framing, and automatic retransmission - requiring only an external CAN transceiver and 120 Ω termination resistor on the bus.
