STM32L431CCT6 Microcontroller ARM Cortex-M4 STM32L4 MCU IC
The STM32L431CCT6 is an ultra-low-power 32-bit microcontroller from STMicroelectronics, featuring a high-performance ARM Cortex-M4 core with Floating Point Unit (FPU) operating at frequencies up to 80 MHz in a compact 48-pin LQFP package. This advanced MCU delivers 256KB of Flash memory and 64KB of SRAM, utilizing 90nm process technology to achieve exceptional energy efficiency with power consumption as low as 8nA in Shutdown mode and 84μA/MHz in Run mode. Operating from a wide supply voltage range of 1.71V to 3.6V and characterized for industrial temperatures from -40°C to +85°C, this device combines high computational performance with sophisticated power management for battery-operated applications. The mcu is fully RoHS compliant and features comprehensive security mechanisms including readout protection, write protection, proprietary code readout protection, and firewall for embedded Flash memory and SRAM.
The STM32L431CCT6 implements the ARM Cortex-M4 core with DSP instruction set extension and Memory Protection Unit (MPU), achieving 1.25 DMIPS/MHz performance (100 DMIPS at 80MHz) and 273.55 CoreMark score. The FPU supports all ARM single-precision data-processing instructions and data types, enabling efficient mathematical computations for signal processing applications. The embedded chip features a flexible clock system with integrated 48MHz internal clock source, clock recovery, and dual PLLs for system clock, audio, and ADC timing. The 32-bit multi-AHB bus matrix connects two APB buses and two AHB buses, ensuring efficient data flow between the core, memories, and peripherals while maintaining deterministic real-time response.
