STMicroelectronics STM32F098CCT6

Overview

STM32F098CCT6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit MCU 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 STM32F098CCT6 datasheet, STM32F098CCT6 pinout, STM32F098CCT6 application, or STM32F098CCT6 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 for high-density PCB layouts.

Technical Context

The STM32F098CCT6 integrates a single-cycle 48 MHz Cortex-M0 core with hardware CRC unit and nested vectored interrupt controller (NVIC) supporting up to 32 external interrupts. Its memory subsystem includes 256 KB Flash with error correction and 32 KB SRAM with hardware parity checking - enabling robust firmware execution in safety-critical edge nodes.

Clock architecture combines four oscillators: 4–32 MHz HSE crystal, 32 kHz LSE for RTC, 8 MHz HSI with x6 PLL, and factory-trimmed 48 MHz HSI48 for USB/CAN timing. Power management supports Sleep/Stop modes with VBAT-backed RTC and backup registers, and independent VDDIO2 supply for mixed-voltage I/O operation.

FAQ

Does STM32F098CCT6 support USB device functionality?

No - the STM32F098CCT6 lacks a USB PHY and dedicated USB controller. It features HDMI CEC and CAN interfaces instead. For USB connectivity, ST recommends the STM32F072 or STM32G071 families, which integrate full-speed USB 2.0 device controllers with internal transceivers and descriptor handling.

What is the maximum operating temperature range for STM32F098CCT6?

The STM32F098CCT6 is qualified for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 of DS10624 Rev 5, specifying ambient operating conditions and thermal derating curves up to 85 °C junction temperature under defined power dissipation limits.

Can the internal 48 MHz oscillator (HSI48) be used for CAN timing?

Yes - the HSI48 oscillator is explicitly qualified for CAN communication per Section 6.3.7 of DS10624 Rev 5, with ±2% factory trim and automatic synchronization to external clocks or USB SOF. It meets CAN bit timing accuracy requirements up to 1 Mbps without external crystal dependency.

Is there hardware support for secure boot or cryptographic operations?

No - the STM32F098CCT6 does not include hardware accelerators for AES, SHA, or secure boot ROM. It relies on software-based validation and external secure elements for cryptographic functions. For integrated security, ST recommends the STM32L5 or STM32H5 series with TrustZone and cryptographic co-processors.
