Product details
Overview
STM32L4P5VET6 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 for 41 µA/MHz run-mode efficiency, operates from 1.71–3.6 V across –40 °C to +85 °C, and delivers 150 DMIPS for real-time embedded control in battery-powered industrial HMI and portable medical devices.
For engineers reviewing the STM32L4P5VET6 datasheet, STM32L4P5VET6 pinout, STM32L4P5VET6 application, or STM32L4P5VET6 equivalent, key selection criteria include verified low-power mode current (190 nA Standby with RTC), dual-bank read-while-write Flash architecture, hardware parity on 64 KB SRAM, and support for Octo-SPI, USB OTG FS, and CAN 2.0B - all confirmed in DS12903 Rev 3.
Technical Context
The STM32L4P5VET6 implements FlexPowerControl with five distinct low-power modes: Shutdown (22 nA), Standby (42 nA or 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). Its ART Accelerator enables zero-wait-state execution from Flash at 120 MHz.
It integrates a full peripheral suite including two 12-bit ADCs (5 Msps), two 12-bit DACs, two op-amps with PGA, two ultra-low-power comparators, Chrom-ART Accelerator (DMA2D), and LCD-TFT controller - all powered from independent analog supplies to ensure signal integrity in mixed-signal applications.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32L4P5VET6 achieves a maximum CPU frequency of 120 MHz, delivering 150 DMIPS (Dhrystone 2.1) and 409.20 CoreMark® (3.41 CoreMark/MHz). This performance is sustained with zero wait states via the ART Accelerator, confirmed in DS12903 Rev 3 Section 3.2 and Table 10.
Does this MCU support external memory expansion, and which interfaces are available?
Yes - it supports external static memories via the Flexible Static Memory Controller (FSMC) for NOR, PSRAM, NAND, and FRAM, plus two Octo-SPI interfaces for high-speed serial flash or RAM. Both are fully documented in Sections 3.18 and 3.19 of DS12903 Rev 3, with timing specifications in Tables 28 and 29.
What are the lowest power consumption figures in retention-capable low-power modes?
In Standby mode with RTC enabled, current draw is 190 nA; in Stop 2 mode with RTC, it is 2.95 µA. These values are measured at 3.3 V and 25 °C, specified in Table 4 (Modes overview) and validated in Section 6.3.5 of DS12903 Rev 3.
Is the LQFP100 package RoHS-compliant and qualified for industrial temperature range?
Yes - the STM32L4P5VET6 in LQFP100 package meets RoHS Directive 2011/65/EU and is qualified for operation from –40 °C to +85 °C, as stated in Section 6.3.1 (General operating conditions) and Package Information Section 7.4 of DS12903 Rev 3.
