STMicroelectronics STM32F401CCU6TR

Summary of STM32F401CCU6TR Product by STMicroelectronics

The STM32F401CCU6TR, manufactured by STMicroelectronics, is a high-performance, low-power microcontroller based on the ARM Cortex-M4 core with FPU, operating up to 84 MHz. As part of the widely adopted STM32F4 family, this 32-bit MCU is tailored for demanding embedded applications that require substantial computing performance, memory resources, and a rich suite of communication peripherals. In its 48-pin UFQFPN package (7x7mm), the STM32F401CCU6TR targets space-constrained designs needing both functional density and robust performance.

Design Structure and Main Features of STM32F401CCU6TR

At the heart of the STM32F401CCU6TR is the ARM Cortex-M4 32-bit RISC processor with integrated Floating Point Unit (FPU) for single-precision operations, supporting extensive DSP instructions—ideal for signal processing, control systems, and real-time response. The core leverages ST’s ART Accelerator™ technology, allowing zero wait-state execution from on-chip Flash even at high clock frequencies, thus maximizing CPU throughput up to 105 DMIPS. A Memory Protection Unit (MPU) further enhances system security and stability, especially in multitasking RTOS environments.

Memory Capabilities of STM32F401CCU6TR

The STM32F401CCU6TR provides a rich set of embedded memories:

Up to 256 KB of high-speed Flash for code and non-volatile data

Up to 64 KB of SRAM for runtime data,

512 bytes of OTP memory for permanent configuration

The multi-AHB bus matrix enables parallel memory and peripheral access, supporting high system bandwidth even during intensive DMA operations. Strong memory resources enable complex firmware and multitasking applications, with ample space for protocol stacks and signal processing algorithms.

Power Supply Options and Power Handling for STM32F401CCU6TR

Supporting an operating voltage range from 1.7V to 3.6V, the STM32F401CCU6TR features flexible power supply concepts with internal voltage regulators and supervisors. Multiple power modes (Run, Sleep, Stop, Standby) allow developers to finely manage power consumption, achieving figures as low as 2.4 μA in Standby mode. Brown-out Reset (BOR), Power-on/Power-down Reset (POR/PDR), and voltage monitoring (PVD) safeguard the device during voltage variations, while the VBAT pin delivers sustained RTC and backup operation during main power loss, crucial for applications like data loggers and always-on security systems.
