Product details
Overview
STM32F098RCY6TR 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 touch panels requiring real-time capacitive sensing, CAN bus connectivity, and analog signal generation.
For engineers reviewing the STM32F098RCY6TR datasheet, STM32F098RCY6TR pinout, STM32F098RCY6TR application, or STM32F098RCY6TR equivalent, key selection criteria include its 48 MHz max CPU frequency, VDD = 1.8 V ±8% operation, 87 fast I/Os (68 with 5V tolerance), HDMI CEC wakeup capability, and UFBGA64 5×5 mm package with 64 terminals.
Technical Context
This MCU integrates a single-cycle Cortex-M0 core with hardware CRC unit, dedicated clock recovery system (CRS) for USB/CAN synchronization, and advanced timer subsystem including one 16-bit advanced-control timer (TIM1) for 6-channel PWM and seven general-purpose timers supporting IR decoding and DAC control.
The analog subsystem combines a 12-bit ADC (16-channel, 0–3.6 V range, separate VDDA supply), two independent 12-bit DACs, two programmable analog comparators, and 23-channel touch sensing controller (TSC) - all operating under unified low-power management with Sleep/Stop modes and VBAT-backed RTC.
Key Specifications

FAQ
What is the maximum operating frequency and voltage range for STM32F098RCY6TR?
The STM32F098RCY6TR operates at up to 48 MHz CPU frequency with a digital supply voltage (VDD) of 1.8 V ±8%, analog supply (VDDA) from 1.8 V to 3.6 V, and selectable I/O supply (VDDIO2) from 1.65 V to 3.6 V. These specifications are validated per DS10624 Rev 5 Section 6.3.1.
Does STM32F098RCY6TR support hardware cryptographic acceleration?
No, the STM32F098RCY6TR does not include hardware cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption tasks. This aligns with its positioning as a cost-optimized, analog-rich MCU rather than a security-focused variant like the STM32L5 or STM32H5 series.
Can the internal 48 MHz oscillator be used for USB communication?
Yes, the internal 48 MHz oscillator with automatic trimming based on external synchronization is qualified for full-speed USB 2.0 operation. Its accuracy remains within ±0.25% when calibrated against an external clock source, satisfying USB timing requirements without needing an external crystal.
What is the function of the HDMI CEC pin, and how is it implemented?
The HDMI CEC functionality is implemented via PA15 (CEC pin), which supports wakeup-on-CEC-header reception in low-power Stop mode. It uses the microcontroller's CEC peripheral to decode and generate CEC messages - enabling remote control interoperability in smart displays without external CEC transceivers.
