Product details
Overview
STM32L4P5CGT6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 120 MHz (150 DMIPS), featuring 1-MB Flash, 320-KB SRAM, LCD-TFT controller, and integrated external SMPS support. It delivers 2.95 µA Stop 2 mode with RTC, 41 µA/MHz Run mode in SMPS configuration, and supports capacitive touch sensing for battery-powered HMI applications.
For engineers reviewing the STM32L4P5CGT6 datasheet, STM32L4P5CGT6 pinout, STM32L4P5CGT6 application, or STM32L4P5CGT6 equivalent, key selection criteria include ultra-low active/standby current, dual-bank read-while-write Flash, hardware parity-checked SRAM, and integrated Chrom-ART Accelerator for TFT graphics rendering.
Technical Context
The device integrates an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, alongside a memory protection unit (MPU) and dual-bank Flash architecture supporting seamless firmware updates. Its power architecture includes configurable voltage scaling (VOS), internal SMPS control logic, and five low-power modes - Shutdown (22 nA), Standby (42 nA), and Stop 2 with RTC (2.95 µA).
Peripherals are routed via a multi-AHB bus matrix with 14-channel DMA, supporting concurrent high-bandwidth operations: Octo-SPI interfaces drive external NOR/FRAM, SAI handles I²S audio streams, and the LCD-TFT controller drives RGB888 panels up to 1024×768 resolution with hardware layer blending.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32L4P5CGT6 operates at up to 120 MHz with its Arm Cortex-M4 core, delivering 150 DMIPS (Dhrystone 2.1) and 409.20 CoreMark® (3.41 CoreMark/MHz). This performance is sustained without wait states thanks to the ART Accelerator, which enables zero-wait-state execution from Flash memory.
Does this MCU support external memory expansion, and if so, what types?
Yes - it supports external static memories via its Flexible Static Memory Controller (FSMC), compatible with SRAM, PSRAM, NOR, NAND, and FRAM. Additionally, two Octo-SPI interfaces enable high-speed x8/x4/x1 SPI NOR/NAND/DRAM-like memory access, with dual Octo-SPI allowing concurrent memory mapping.
How does the low-power capability compare between LDO and SMPS configurations?
In LDO mode, active current is 110 µA/MHz; in external SMPS mode, it drops to 41 µA/MHz - a 63% reduction. The MCU includes dedicated SMPS control logic (VDDSMPS, VDDA_SMPS pins) and internal regulators to manage switching converter feedback, enabling efficient sub-100 µA/MHz operation across temperature ranges.
Is the LCD-TFT controller capable of driving standard RGB panels, and what resolution is supported?
Yes - the integrated LCD-TFT controller supports RGB666 and RGB888 interfaces with up to three layers (foreground, background, alpha-blended), hardware clipping, and dithering. It drives resolutions up to 1024×768 at 60 Hz, with programmable pixel clock and timing registers compliant with common TFT timing requirements.
