Product details
Overview
STM32L4P5VGT6 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 SMPS support. It delivers 41 µA/MHz in SMPS-run mode, 190 nA Standby with RTC, and supports capacitive touch sensing - deployed in battery-powered medical monitors and portable industrial HMI systems.
For engineers reviewing the STM32L4P5VGT6 datasheet, STM32L4P5VGT6 pinout, STM32L4P5VGT6 application, or STM32L4P5VGT6 equivalent, key selection criteria include its dual-bank read-while-write Flash architecture, hardware parity-protected SRAM, 2×12-bit ADCs (5 Msps), LCD-TFT interface timing, and low-power mode wakeup latency (5 µs from Stop).
Technical Context
The STM32L4P5VGT6 integrates an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, alongside a memory protection unit (MPU) and FlexPowerControl for dynamic voltage scaling across seven low-power modes. Its interconnect matrix routes 23 peripherals-including USB OTG FS, CAN 2.0B, dual Octo-SPI, and SAIs-via a 14-channel DMA controller and AHB bus matrix.
Core clocking uses three PLLs (system, USB, audio/ADC), internal oscillators trimmed by LSE (±0.25%), and external crystal support (4–48 MHz). Analog subsystem includes two 12-bit DACs with sample-and-hold, two op-amps with PGA, and DFSDM digital filters - all with independent supply domains for noise isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power Cortex-M4 MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L4R9VIT6 | Same LQFP100 package, 2 MB Flash, 640 KB SRAM, no SMPS support, higher max temp (+125 °C) | Better suited for high-memory GUI applications without external SMPS; lacks integrated SMPS driver control logic | Select when larger code footprint or extended temperature is required, and external DC-DC is already present |
| STM32U575ZIT6 | Arm Cortex-M33 core, TrustZone, 2 MB Flash, 786 KB SRAM, 1.5x lower active power, no LCD-TFT controller | Targeted at security-critical IoT endpoints; lacks native display interface but adds PSA-certified secure boot | Choose for cloud-connected devices needing hardware root-of-trust, where display is handled externally or omitted |
Compared with STM32L4R9VIT6, the STM32L4P5VGT6 offers integrated SMPS control and lower standby current (190 nA vs. 420 nA), while STM32U575ZIT6 trades LCD-TFT capability for TrustZone security and deeper power savings - making each optimal for distinct system-level priorities: power-constrained display HMI, memory-rich industrial UI, or certified secure edge node.

FAQ
Does STM32L4P5VGT6 support external SDRAM via FSMC?
Yes, the Flexible Static Memory Controller (FSMC) supports external SDRAM, SRAM, PSRAM, NOR, NAND, and FRAM memories. For SDRAM, it implements a 16-bit data bus with row/column addressing, refresh control, and burst-mode access - validated in ST's AN4821 application note and supported in STM32CubeMX v6.5+.
What is the maximum resolution and refresh rate achievable with the LTDC controller?
The LCD-TFT controller (LTDC) supports up to WXGA (1366×768) at 60 Hz with 24-bit RGB interface. Pixel clock frequency is limited to 65 MHz; actual refresh rate depends on panel timing parameters, memory bandwidth, and DMA2D layer composition overhead - verified using ST's STM32L4P5G-DK evaluation board and TouchGFX SDK.
Can the internal SMPS be used to power external circuitry?
No - the integrated SMPS is designed exclusively to regulate Vcore and Vddio domains within the MCU. Its feedback loop, compensation network, and output stage are not accessible or configurable for external loads. External DC-DC converters must be used for auxiliary rails.
How many capacitive sensing channels does the TSC support on this variant?
The Touch Sensing Controller (TSC) supports up to 24 capacitive sensing channels, configurable as touchkeys, linear sliders, or rotary wheels. All 24 channels are available on the LQFP100 package (pins PA0–PA7, PB0–PB15, PC0–PC3), with simultaneous scanning and hardware-based noise filtering per DS12903 Section 3.29.
