Product details
Overview
STM32L4R5QGI6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 120 MHz max frequency, 2 MB Flash, 640 KB SRAM, and integrated MIPI DSI host controller + LCD-TFT controller. It supports external SMPS for 43 µA/MHz run-mode efficiency and operates from -40 °C to 125 °C, targeting battery-powered HMI and portable medical displays.
For engineers reviewing the STM32L4R5QGI6 datasheet, STM32L4R5QGI6 pinout, STM32L4R5QGI6 application, or STM32L4R5QGI6 equivalent, key selection criteria include its dual-bank read-while-write Flash, Chrom-ART Accelerator (DMA2D), 24-channel capacitive touch sensing, and 136 I/Os with 5 V tolerance - critical for high-resolution graphical user interfaces in constrained power environments.
Technical Context
This MCU integrates an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, alongside a multi-AHB interconnect matrix that decouples CPU, DMA, and peripheral bus access to sustain throughput under mixed workloads. Its power architecture includes three low-power modes (Stop 2, Standby with RTC, Shutdown) with validated current draws of 2.8 µA, 420 nA, and 33 nA respectively.
The device features two independent analog domains supporting simultaneous operation: one for 12-bit 5 Msps ADC with hardware oversampling up to 16-bit, and another for dual 12-bit DACs, two op-amps with PGA, and two ultra-low-power comparators - all with dedicated voltage regulation and independent supply pins.

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 |
|---|---|---|---|
| STM32L4R5VIT6 | LQFP100 package (100 pins), no MIPI DSI, reduced I/O count (82), same core/peripherals otherwise | Suitable for non-display applications requiring lower pin count and simpler PCB layout | Select when graphical interface is unnecessary and cost-sensitive LQFP packaging is preferred |
| STM32L4R9ZIJ6 | UFBGA144 package (144 pins), adds crypto acceleration (AES-256, PKA), same Flash/SRAM but higher temp grade (−40 to 125 °C) | Required for secure boot, OTA update signing, or industrial environments exceeding 85 °C ambient | Choose when cryptographic operations or extended temperature operation are mandatory |
Compared with STM32L4R5QGI6, the STM32L4R5VIT6 sacrifices display capability and I/O density for cost and layout simplicity, while the STM32L4R9ZIJ6 adds security IP and thermal margin at the expense of larger package and higher unit cost - making the QGI6 optimal for balanced display-centric, battery-powered designs.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32L4R5QGI6 achieves a maximum CPU frequency of 120 MHz, delivering 150 DMIPS (Dhrystone 2.1) and 409.20 CoreMark® (3.41 CoreMark/MHz). This performance level is sustained via the ART Accelerator, which eliminates Flash wait states, enabling deterministic real-time execution for control and signal processing tasks without external memory.
Does STM32L4R5QGI6 support external memory expansion, and what interfaces are available?
Yes, it supports external memory via two OctoSPI interfaces (each capable of x1/x2/x4/x8 configurations) and a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, NAND, and FRAM. These interfaces enable seamless attachment of external graphics framebuffers, code storage, or data logging memory - critical for applications exceeding on-chip SRAM capacity.
How does the MIPI DSI interface differ from traditional parallel LCD interfaces on this MCU?
The MIPI DSI interface provides high-speed, low-power, differential signaling (up to 500 Mbit/s per lane) with embedded clock recovery and ultra-low-power (ULP) mode transitions - unlike parallel RGB interfaces, it reduces EMI, simplifies routing, and enables dynamic refresh rate scaling. Combined with the integrated LTDC controller, it allows direct drive of modern DSI displays without external bridge ICs.
What are the key low-power modes and their typical use cases?
Key modes include Shutdown (33 nA, 5 wakeup pins), Standby with RTC (420 nA), and Stop 2 with RTC (2.8 µA). Shutdown is used for deep sleep between user interactions; Standby retains RTC and backup registers during transport/storage; Stop 2 maintains SRAM content and peripheral clocks for rapid wake-up during sensor polling cycles - all validated per DS12023 Rev 5 electrical characteristics.
