STMicroelectronics STM32L4P5VGY6TR

Overview

STM32L4P5VGY6TR 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 STM32L4P5VGY6TR datasheet, STM32L4P5VGY6TR pinout, STM32L4P5VGY6TR application, or STM32L4P5VGY6TR equivalent, key selection criteria include ultra-low-power operation across multiple sleep modes, dual-bank Flash with read-while-write capability, hardware cryptographic acceleration (SHA-256), and integrated LCD-TFT timing control for embedded display systems.

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 interface, and five low-power modes - Shutdown (22 nA), Standby (190 nA with RTC), and Stop 2 (2.95 µA with RTC).

Peripherals are managed via a multi-AHB bus matrix and 14-channel DMA controller. Clocking uses three PLLs (system, USB, audio/ADC), internal 48 MHz RC with clock recovery, and dedicated LSE-driven RTC with hardware calendar and calibration - all coordinated by the RCC and PWR controllers.

FAQ

What is the maximum operating frequency and corresponding performance metric?

The STM32L4P5VGY6TR operates at up to 120 MHz using its Arm Cortex-M4 core with FPU. Its performance is quantified at 150 DMIPS (Dhrystone 2.1) and 409.20 CoreMark® (3.41 CoreMark/MHz). The ART Accelerator ensures zero-wait-state execution from Flash memory, enabling deterministic real-time behavior critical for motor control and metrology applications.

Does this MCU support external memory expansion, and if so, what types?

Yes, the STM32L4P5VGY6TR supports external memory via two Octo-SPI interfaces and a Flexible Static Memory Controller (FSMC). It can interface with SPI NOR/NAND flash, PSRAM, FRAM, and SRAM devices. The Octo-SPI supports x1/x2/x4/x8 configurations up to 133 MHz, enabling memory-mapped execution for large firmware images or graphics frame buffers.

How does the power management architecture enable ultra-low-power operation?

The MCU implements 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 (110 µA/MHz) or external SMPS (41 µA/MHz). Voltage scaling, automatic clock gating, and peripheral-specific power gating allow granular energy control - for example, keeping LPTIM and RTC active while disabling CPU and Flash in Stop mode.

Is hardware cryptographic acceleration included, and what algorithms does it support?

Yes, the STM32L4P5VGY6TR includes a dedicated HASH hardware accelerator supporting SHA-256. It also features a true random number generator (RNG) compliant with NIST SP800-90B and a 96-bit unique device identifier. These blocks enable secure boot, firmware signature verification, and TLS session key generation without CPU intervention or software library dependencies.
