Product details
Overview
STM32F401CCY6BTT from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, delivering 105 DMIPS at 84 MHz, featuring 256 KB Flash, 64 KB SRAM, and integrated peripherals including 1×12-bit 2.4 MSPS ADC, USB 2.0 FS OTG, and up to 11 communication interfaces. It targets low-power embedded control in industrial sensors, portable medical devices, and smart home hubs requiring deterministic real-time response and compact BGA packaging.
For engineers reviewing the STM32F401CCY6BTT datasheet, STM32F401CCY6BTT pinout, STM32F401CCY6BTT application, or STM32F401CCY6BTT equivalent, key selection criteria include ART Accelerator™-enabled zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 78 fast I/Os), sub-10 µA Stop mode power consumption, and WLCSP49 package suitability for space-constrained PCB layouts.
Technical Context
The device implements an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states across full 84 MHz operation, enabling deterministic code execution critical for motor control and audio processing. Its memory protection unit (MPU) supports secure partitioning of firmware tasks, while the dual-clock domain (HSI/HSI16 + HSE 4–26 MHz) enables precise timing for RTC, USB, and synchronous serial interfaces.
Peripheral integration follows a multi-AHB bus matrix architecture supporting concurrent DMA transfers across 16-stream controllers, allowing simultaneous ADC sampling, SPI audio streaming, and USB data upload without CPU intervention. The embedded SWJ-DP debug interface and ETM trace capability provide non-intrusive real-time profiling for safety-critical firmware validation.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F401CCY6BTT achieves 84 MHz maximum CPU frequency using its internal PLL driven by either the 4–26 MHz HSE crystal or 16 MHz HSI RC oscillator. The ART Accelerator™ eliminates Flash wait states, enabling full-speed execution directly from embedded Flash memory without external cache or SRAM code relocation.
Does this MCU support USB device functionality without external components?
Yes - the STM32F401CCY6BTT integrates a full-speed USB 2.0 OTG controller with an on-chip PHY, requiring only a standard USB Type-A/B receptacle, series resistors, and ESD protection diodes. No external transceiver or clock source is needed for basic HID, CDC, or MSC class operation.
What are the key low-power modes and their typical current draw?
It supports Run (128 µA/MHz), Stop (10 µA typ in Deep Power Down), and Standby (2.4 µA @25°C) modes. Stop mode retains SRAM and register content with fast wakeup (<10 µs), while Standby mode powers down the entire system except RTC and backup registers, enabling calendar-based wakeups.
How many I/O pins support 5 V tolerance and what is the significance?
All 81 GPIOs are 5 V tolerant, meaning they accept input voltages up to 5.5 V regardless of VDD level (1.7–3.6 V). This allows direct interfacing with legacy 5 V logic, sensors, and displays without level-shifting circuitry - reducing BOM cost and PCB complexity in mixed-voltage systems.
