STMicroelectronics STM32F098CCT7

Overview

STM32F098CCT7 from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 256 KB Flash, 32 KB SRAM (HW parity), integrated CAN 2.0B interface, dual 12-bit DAC, and 12-bit ADC (1.0 µs conversion) - deployed in industrial HMI touch panels requiring real-time capacitive sensing, CAN bus connectivity, and analog signal generation.

For engineers reviewing the STM32F098CCT7 datasheet, STM32F098CCT7 pinout, STM32F098CCT7 application, or STM32F098CCT7 equivalent, key selection criteria include its 48 MHz max CPU frequency, 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 STM32F098CCT7 integrates a single-cycle Cortex-M0 core with hardware CRC unit and advanced power management supporting Sleep/Stop modes plus VBAT-backed RTC and backup registers. Its clock system combines internal 48 MHz oscillator (auto-trimmed via external sync), 4–32 MHz HSE, and 32 kHz LSE for precise timekeeping.

Analog subsystem includes one 12-bit ADC (16-channel, 0–3.6 V range, separate VDDA supply), two 12-bit DAC channels, two programmable comparators, and 23-channel touch sensing controller (TSC) - all operating under unified 1.8 V digital supply while maintaining analog integrity via dedicated voltage domains.

FAQ

What is the maximum operating temperature range for STM32F098CCT7?

The STM32F098CCT7 is specified for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 of DS10624 Rev 5, where ambient operating conditions define TA = –40 to 85 °C with derating applied above 70 °C for certain power configurations.

Does STM32F098CCT7 support USB device functionality?

No, STM32F098CCT7 does not include a USB PHY or USB controller. It lacks dedicated USB pads and register sets. The device offers HDMI CEC and CAN interfaces instead - verified in Section 3.19 and Table 1 of DS10624 Rev 5, which list supported peripherals without USB enumeration.

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

Yes, the internal 48 MHz oscillator (HSI48) is CAN-capable and explicitly qualified for CAN bit timing in DS10624 Rev 5 Section 6.3.7. It features automatic trimming using external clock synchronization, achieving ±1.5% accuracy over temperature - sufficient for CAN up to 1 Mbit/s without external crystal.

How many independent power domains does STM32F098CCT7 have?

STM32F098CCT7 has three independent power domains: VDD/VSS (1.8 V digital core), VDDA/VSSA (2.4–3.6 V analog), and VDDIO2 (1.65–3.6 V for selected I/Os). This separation is documented in Section 3.5.1 and Figure 11 of DS10624 Rev 5, enabling noise isolation between digital switching and precision analog circuits.
