Product details
Overview
STM32F098RCH6 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 STM32F098RCH6 datasheet, STM32F098RCH6 pinout, STM32F098RCH6 application, or STM32F098RCH6 equivalent, key selection factors include its 48 MHz max CPU frequency, 64-pin LQFP package with 5V-tolerant I/Os, HDMI CEC wakeup capability, and hardware CRC unit for firmware integrity verification.
Technical Context
The STM32F098RCH6 integrates a single-cycle Cortex-M0 core with tightly coupled NVIC, supporting nested interrupts and low-latency peripheral response. Its clock system combines internal oscillators (HSI48 with auto-trimming, 8 MHz HSI, 40 kHz LSI) and external sources (4–32 MHz HSE, 32.768 kHz LSE), enabling precise RTC calibration and USB-free device synchronization via CRS.
Peripheral architecture includes a 12-channel DMA controller, advanced-control timer (TIM1) for 6-channel PWM, and dual comparators with programmable hysteresis-enabling real-time motor control, capacitive touch sensing (up to 23 channels), and analog signal conditioning without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072RBT6 | Same Cortex-M0 core, 128 KB Flash, no CAN, no HDMI CEC, 1× DAC channel | Lacks CAN and CEC; suitable for cost-sensitive USB-connected devices without automotive bus requirements | Select when CAN and CEC are unnecessary and Flash size can be halved. |
| STM32F078VBH6 | Same 256 KB Flash, 32 KB SRAM, but 100-pin LQFP, adds USB 2.0 FS, removes CEC and TSC | USB host/device capability replaces CEC; larger package accommodates more peripherals but increases PCB area | Choose for USB-centric designs requiring HID or CDC class support instead of HDMI ecosystem integration. |
Compared with STM32F098RCH6, STM32F072RBT6 trades CAN and CEC for lower cost and smaller footprint, while STM32F078VBH6 exchanges CEC and touch sensing for USB functionality-making the RCH6 uniquely suited for CAN+CEC coexistence in compact industrial or consumer electronics.

FAQ
What is the maximum operating frequency and supply voltage range for the STM32F098RCH6?
The STM32F098RCH6 operates at up to 48 MHz using its internal HSI48 oscillator or external crystal. Its digital supply (VDD) is strictly 1.8 V ±8% (1.656–1.944 V); analog supply (VDDA) ranges from 1.8 V to 3.6 V. Operation outside these ranges violates absolute maximum ratings and may cause functional failure or permanent damage.
Does the STM32F098RCH6 support USB connectivity?
No, the STM32F098RCH6 does not include a USB peripheral. It features CAN 2.0B, multiple USARTs (including ISO7816 and IrDA), I²C, SPI/I²S, and HDMI CEC-but no USB PHY or USB controller. For USB-capable variants in the same family, consider the STM32F078VBH6 or STM32F042K6T6.
How many I/O pins are 5V-tolerant, and which ones support independent VDDIO2?
The STM32F098RCH6 provides up to 68 I/Os across the full family; in the LQFP64 package, 51 GPIOs are available, with up to 5V-tolerant capability on most pins. Specifically, 19 I/Os (including PA0–PA7, PB0–PB1, PC0–PC7, PD0–PD2) support independent VDDIO2 supply (1.65–3.6 V), enabling direct interfacing with 3.3 V or 5 V logic without level shifters.
What debug interface does the STM32F098RCH6 use, and what pins are required?
The STM32F098RCH6 uses Serial Wire Debug (SWD), requiring only two pins: SWDIO (PA13) and SWCLK (PA14). No JTAG pins are needed, reducing debug footprint. NRST is optional but recommended for reliable reset control during programming and debugging sessions.
