STMicroelectronics STM32F401CCY6TR

Overview

STM32F401CCY6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 256 KB Flash, 64 KB SRAM, and 84 MHz max CPU frequency. It integrates one 12-bit 2.4 MSPS ADC, up to 11 communication interfaces (including USB OTG FS, SPI, I²C, USART), and supports -40 °C to 85 °C operation in a 48-pin UFQFPN package. It is used in portable medical sensors requiring low-power real-time signal acquisition and USB-based data upload.

For engineers reviewing the STM32F401CCY6TR datasheet, STM32F401CCY6TR pinout, STM32F401CCY6TR application, or STM32F401CCY6TR equivalent, key selection criteria include Flash/SRAM size, USB OTG FS capability, 12-bit ADC performance at ≥2 MSPS, low-power Stop mode current (<42 µA), and UFQFPN48 package compatibility with space-constrained PCB layouts.

Technical Context

The device implements an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 84 MHz. Its memory subsystem includes 256 KB of embedded Flash with ECC support, 64 KB of SRAM, and 512 bytes of OTP memory for secure configuration storage.

Power management features include three low-power modes (Stop with fast/slow wakeup, Standby), programmable voltage scaling, and independent VBAT supply for RTC backup. Clocking supports 4–26 MHz external crystal, internal 16 MHz RC, and 32 kHz RTC oscillator with calibration.

FAQ

What is the maximum operating frequency and core type of STM32F401CCY6TR?

The STM32F401CCY6TR features an Arm Cortex-M4 core with FPU, rated for up to 84 MHz operation. It delivers 105 DMIPS at this frequency, validated under standard conditions (VDD = 3.3 V, Tj = 25 °C) per DS9716 Rev 11. The ART Accelerator™ ensures zero-wait-state execution from Flash memory at full speed.

Does STM32F401CCY6TR include an integrated USB physical layer?

Yes, STM32F401CCY6TR integrates a full-speed USB 2.0 OTG controller with an on-chip PHY. This eliminates the need for external transceivers in USB device, host, or OTG configurations. Pin assignments USB_DP and USB_DM are dedicated, 3.3 V-tolerant, and compliant with USB specification timing requirements.

What are the low-power mode current specifications for STM32F401CCY6TR?

In Stop mode with Flash in deep power-down and slow wakeup, typical current is 10 µA at 25 °C; maximum is 28 µA. In Standby mode without RTC, it draws 2.4 µA at 25 °C and 1.7 V. These values are measured per DS9716 Rev 11 Section 6.3.7 and assume proper configuration of regulators and clocks.

Which package and pin count does STM32F401CCY6TR use?

STM32F401CCY6TR uses the UFQFPN48 package: 48-pin, 7 mm × 7 mm body, 0.5 mm pitch, with exposed thermal pad. This is confirmed in Table 1 and Section 7.2 of DS9716 Rev 11. The 'Y' in the part number explicitly denotes the UFQFPN48 variant per ST's ordering code convention.
