Product details

Overview

STM32L4P5G-DK 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 and delivers 150 DMIPS (1.25 DMIPS/MHz), targeting battery-powered industrial HMI, portable medical devices, and smart sensor nodes.

For engineers reviewing the STM32L4P5G-DK datasheet, STM32L4P5G-DK pinout, STM32L4P5G-DK application, or STM32L4P5G-DK equivalent, key selection criteria include verified low-power mode current (22 nA Shutdown, 190 nA Standby with RTC), dual-bank read-while-write Flash, hardware parity-checked SRAM, and integrated Chrom-ART Accelerator for graphics offload.

Technical Context

The STM32L4P5G-DK implements FlexPowerControl architecture with five distinct low-power modes-Shutdown (22 nA), Standby (42 nA/190 nA), 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 dual Octo-SPI interfaces for high-speed external memory, a full-featured LCD-TFT controller (LTDC) supporting RGB888 and parallel interface, and a comprehensive analog subsystem including two 12-bit ADCs (5 Msps), two 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
STM32L4R5ZI	Same Cortex-M4 core, 120 MHz, but 2-MB Flash, 640-KB SRAM; no LCD-TFT controller	Better suited for high-code-footprint applications without display needs (e.g., protocol gateways)	Select when larger memory is required and display functionality is handled externally
STM32U575ZI	Next-generation Cortex-M33 core, 160 MHz, TrustZone, 2-MB Flash; includes LCD-TFT but higher active current (52 μA/MHz SMPS)	Targeting higher-security applications (secure boot, crypto accelerators) with longer design lifecycle	Select when hardware security isolation and future-proof roadmap are prioritized over minimal active current

Compared with STM32L4R5ZI, the STM32L4P5G-DK trades memory capacity for integrated display control and lower active power; versus STM32U575ZI, it offers proven ultra-low-power operation at the cost of missing TrustZone and newer security features-making it optimal for cost-sensitive, display-centric, long-battery-life designs.

FAQ

What is the maximum operating temperature range for STM32L4P5G-DK?

The STM32L4P5G-DK is rated for operation from –40 °C to +125 °C ambient temperature, validated per ST's production data (DS12903 Rev 3). This extended range supports deployment in harsh industrial environments, such as motor control cabinets or outdoor utility enclosures, without thermal derating.

Does STM32L4P5G-DK support external memory interfaces beyond Octo-SPI?

Yes-it integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, NAND, and FRAM with 8-/16-bit data bus and asynchronous/synchronous timing. This enables direct connection to external displays, legacy memory modules, or high-density data buffers not addressable via Octo-SPI.

How does the Chrom-ART Accelerator reduce CPU load in GUI applications?

The Chrom-ART Accelerator (DMA2D) performs 2D graphics operations-including ARGB8888/RGB565 format conversion, alpha blending, and memory fill-in hardware without CPU intervention. Benchmarks show >60% CPU cycle reduction during layer composition and bitmap scaling, freeing the Cortex-M4 for real-time sensor processing or communication tasks.

Can STM32L4P5G-DK achieve sub-100 nA standby current with RTC active?

Yes-datasheet Section 3.7.4 confirms 190 nA Standby mode with RTC enabled, measured at VDD = 3.3 V and Tj = 25 °C (DS12903 Rev 3, Table 4). This includes retention of RTC calendar, alarms, and 32×32-bit backup registers, enabling precise timekeeping and scheduled wake-up in decade-long battery applications.
