STM32L452CEU6 Microcontroller - STMicroelectronics

The STM32L452CEU6 from STMicroelectronics is a cutting-edge ultra-low-power microcontroller belonging to the STM32L4 series, which is engineered for optimal performance and energy efficiency. This microcontroller is based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating Point Unit (FPU) which supports all Arm single-precision data-processing instructions and data types, making it ideal for scientific and audio applications.

With a memory configuration of 512KB of Flash memory and 160KB of SRAM, the STM32L452CEU6 provides ample storage for complex applications. Additionally, it offers a range of enhanced I/Os and peripherals, making it highly flexible for a variety of applications ranging from industrial controls to consumer electronics.

Key features of the STM32L452CEU6 include:

• Energy-efficient Arm® Cortex®-M4 core with FPU and Adaptive real-time accelerator (ART Accelerator™) for zero-wait-state execution from Flash memory
• Dynamic voltage scaling to balance power consumption with processing demand
• 12-bit, 5 MSPS analog-to-digital converters (ADCs) with up to 16 channels
• Two ultra-low-power comparators
• Serial wire debug (SWD) & JTAG interfaces
• USB 2.0 full-speed device with crystal-less LPM and BCD support
• Several timers, including a low-power timer and a high-resolution timer for accurate control
• Rich set of communication interfaces: I2C, USARTs, SPIs, CAN, and USB

The STM32L452CEU6 also incorporates numerous built-in hardware security features such as a True Random Number Generator (TRNG) and a set of cryptographic hardware accelerators for AES, Public Key Authority (PKA), and HASH (MD5, SHA-1, SHA-2) algorithms. These features ensure secure data transfer and storage, which is crucial for modern IoT applications.

Designed for flexibility, the STM32L452CEU6 is available in a UFBGA73 package and is fully compatible with the extensive STM32 ecosystem, which includes tools for development, testing, and production. Developers can take advantage of the STM32Cube software suite to streamline development and reduce time to market.
