Product details
Overview
STM32L4P5VGY6PTR 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 41 µA/MHz in SMPS-run mode, 190 nA Standby with RTC, and supports capacitive touch sensing for battery-powered HMI applications.
For engineers reviewing the STM32L4P5VGY6PTR datasheet, STM32L4P5VGY6PTR pinout, STM32L4P5VGY6PTR application, or STM32L4P5VGY6PTR equivalent, key selection criteria include ultra-low-power operation across multiple sleep modes, dual-bank read-while-write Flash, hardware parity-checked SRAM, and integrated LCD-TFT timing control for embedded display systems.
Technical Context
The device integrates an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 120 MHz, and a multi-layer AHB bus matrix with 14-channel DMA for concurrent peripheral access. Its power architecture includes FlexPowerControl with five low-power modes-Shutdown (22 nA), Standby (190 nA with RTC), Stop 2 (2.95 µA with RTC), and Run modes optimized for LDO or external SMPS supply.
Clock management features three PLLs (system, USB/audio, ADC), internal multispeed oscillator auto-trimmed by LSE (±0.25%), and 48 MHz clock recovery. Analog subsystem includes two 12-bit ADCs (5 Msps), two 12-bit DACs, two op-amps with PGA, and two ultra-low-power comparators-all with independent supply domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L4R5ZIT6 | Same core/peripherals but LQFP144 (144-pin), 2-MB Flash, no external SMPS support, higher pin count | Better suited for complex HMI with larger display, more sensors, or Ethernet PHY interface | Select when >1-MB code space or additional I/Os are required; not drop-in compatible due to package and power architecture |
| STM32U575ZIT6 | Arm Cortex-M33 core, TrustZone, 2-MB Flash, 780 nA Stop mode, no LTDC, different clock tree | Targeted at security-critical IoT endpoints requiring PSA-certified firmware isolation | Choose for enhanced security compliance; requires redesign for graphics and analog subsystem migration |
Compared with STM32L4R5ZIT6, the STM32L4P5VGY6PTR offers lower system BOM cost via integrated SMPS control and smaller footprint, while the STM32U575ZIT6 trades display capability for hardware-enforced security-making the L4P5 optimal for cost-sensitive, display-rich, battery-operated edge devices.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating?
The STM32L4P5VGY6PTR operates at up to 120 MHz with an ART Accelerator enabled, achieving 150 DMIPS (1.25 DMIPS/MHz per Dhrystone 2.1). This performance is sustained with zero wait states from Flash memory, verified under industrial temperature conditions (–40 °C to +85 °C) and 3.3 V supply.
Does this MCU support external SMPS control, and how is it implemented?
Yes-STM32L4P5VGY6PTR integrates dedicated SMPS control logic including synchronous buck converter drivers (SW1/SW2 pins), feedback monitoring (FB pin), and enable/disable sequencing. It supports external DC-DC converters such as the ST1PS01 or discrete MOSFET-based designs, reducing active-mode current to 41 µA/MHz versus 110 µA/MHz in LDO mode.
What display interfaces does the STM32L4P5VGY6PTR support, and what is the maximum resolution?
The MCU includes a full-featured LCD-TFT controller (LTDC) supporting RGB parallel interfaces up to WXGA (1366×768) at 60 Hz. It provides two display layers with alpha blending, dithering, and programmable timing generators. The Chrom-ART Accelerator (DMA2D) handles 2D graphics composition independently of the CPU.
How many low-power modes are available, and what is the lowest current draw with RTC active?
Six low-power modes are supported: Shutdown (22 nA), Standby (190 nA with RTC), Stop 2 (2.95 µA with RTC), Stop 1, Low-power Run, and Low-power Sleep. The 190 nA Standby mode retains RTC operation, 32×32-bit backup registers, and five wakeup pins-verified per DS12903 Rev 3, Table 4 and Section 3.7.4.
