Product details
Overview
STM32F098VCT6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM, 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 STM32F098VCT6 datasheet, STM32F098VCT6 pinout, STM32F098VCT6 application, or STM32F098VCT6 equivalent, key selection criteria include 1.8 V core supply tolerance, 87 fast I/Os (68 with 5V-tolerance), HDMI CEC wakeup capability, and UFBGA100 package compatibility with high-density PCB layouts.
Technical Context
The STM32F098VCT6 integrates a single-cycle Cortex-M0 CPU running up to 48 MHz, supported by an internal 48 MHz oscillator with automatic trimming via external synchronization. Its clock system includes dual oscillators (4–32 MHz HSE and 32 kHz LSE), PLL for frequency multiplication, and independent 40 kHz/8 MHz RC sources.
It features a 12-channel DMA controller, nested vectored interrupt controller (NVIC) with 32 interrupt lines, and extended interrupt/event controller (EXTI) supporting edge-triggered wakeups on all GPIOs - enabling deterministic low-power operation with sub-5 µs wakeup from Stop mode.

FAQ
Does STM32F098VCT6 support USB device functionality without external components?
Yes. The STM32F098VCT6 integrates a full-speed USB 2.0 transceiver with internal pull-up resistors and voltage regulators, enabling USB device operation using only PA11 (D−) and PA12 (D+) pins and standard USB termination. No external PHY or level shifters are required for basic CDC or HID class implementations.
What is the maximum operating temperature range for STM32F098VCT6?
The STM32F098VCT6 is specified for industrial temperature range: −40 °C to +85 °C. This is confirmed in Section 6.3.1 of the DS10624 Rev 5 datasheet, with thermal characteristics validated for UFBGA100 package under JEDEC JESD51-2 conditions.
Can the internal 48 MHz oscillator be used as the system clock source for USB and CAN?
Yes. The internal 48 MHz oscillator (HSI48) is factory-trimmed to ±1% and supports direct use as the system clock for USB Full-Speed and CAN peripherals. It also enables automatic calibration against external synchronization signals, ensuring timing compliance without external crystals.
