Product details
Overview
STM32L4P5CGU6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 120 MHz max frequency, 1 MB Flash, 320 KB SRAM, and integrated LCD-TFT controller. It supports external SMPS, operates from 1.71–3.6 V, achieves 190 nA Standby with RTC, and targets battery-powered industrial sensors and portable medical devices.
For engineers reviewing the STM32L4P5CGU6 datasheet, STM32L4P5CGU6 pinout, STM32L4P5CGU6 application, or STM32L4P5CGU6 equivalent, key selection criteria include ultra-low-power mode current (e.g., 22 nA Shutdown), dual-bank read-while-write Flash, hardware parity on 64 KB SRAM, and support for Octo-SPI and USB OTG FS with LPM.
Technical Context
The STM32L4P5CGU6 implements FlexPowerControl architecture with five low-power modes (Shutdown, Standby, Stop 2, Low-power Run, Run), each with distinct voltage regulator configuration (LDO or external SMPS) and peripheral retention. Its ART Accelerator enables zero-wait-state execution from Flash at 120 MHz.
It integrates three PLLs (system, USB/audio, ADC), a 14-channel DMA controller, and an interconnect matrix routing peripherals to AHB/APB buses. The device includes two 12-bit ADCs (5 Msps), two DACs, two op-amps with PGA, and Chrom-ART Accelerator (DMA2D) for graphics offload - all operating under independent supply domains.

FAQ
What is the maximum operating frequency and core type of the STM32L4P5CGU6?
The STM32L4P5CGU6 features an Arm Cortex-M4 core with FPU, rated for up to 120 MHz operation. It delivers 150 DMIPS at this frequency using the ART Accelerator for zero-wait-state Flash execution. The core includes a Memory Protection Unit (MPU) and full DSP instruction set, enabling deterministic real-time control and signal processing tasks.
Does the STM32L4P5CGU6 support external SMPS, and how does it affect power consumption?
Yes, the STM32L4P5CGU6 supports external switched-mode power supply (SMPS) via dedicated VDDSMPS and VDDIO2 pins. In SMPS mode, active current drops to 41 µA/MHz (vs. 110 µA/MHz in LDO mode), significantly extending battery life in continuous operation. This configuration requires external SMPS circuitry but enables optimal efficiency across wide load ranges.
What display interfaces does the STM32L4P5CGU6 provide, and what resolutions are supported?
The STM32L4P5CGU6 integrates a full LCD-TFT controller (LTDC) supporting RGB, YUV, and CYMK pixel formats with up to 24-bit color depth. It drives displays up to WXGA (1366×768) resolution at 60 Hz using external SDRAM as frame buffer. The controller includes layer blending, alpha channel support, and dithering - eliminating need for external display drivers in mid-range HMI designs.
How many analog-to-digital converters does the STM32L4P5CGU6 include, and what are their key specifications?
The STM32L4P5CGU6 includes two independent 12-bit ADCs, each capable of 5 Msps sampling rate. Both support hardware oversampling up to 16-bit effective resolution and operate with 200 µA/Msps power efficiency. They feature fully differential inputs, programmable sampling time, and built-in offset/gain calibration - enabling high-precision sensor measurement in battery-constrained systems.
