Product details
Overview
STM32L4R9ZGJ6 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 - deployed in battery-powered industrial HMIs and portable medical displays requiring high-resolution graphics and sub-μA standby operation.
For engineers reviewing the STM32L4R9ZGJ6 datasheet, STM32L4R9ZGJ6 pinout, STM32L4R9ZGJ6 application, or STM32L4R9ZGJ6 equivalent, key selection criteria include its dual-bank read-while-write Flash architecture, 43 μA/MHz SMPS-enabled Run mode, Chrom-ART Accelerator (DMA2D), 24-channel capacitive touch sensing, and UFBGA144 10 × 10 mm package with 136 fast I/Os (most 5 V-tolerant).
Technical Context
This MCU implements an adaptive real-time memory accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 120 MHz, paired with a multi-AHB interconnect matrix for concurrent peripheral access. Its power architecture integrates three independent voltage regulators (LDO/SMPS/backup), supporting five low-power modes including 33 nA Shutdown and 420 nA Standby with RTC.
The graphics subsystem combines Chrom-ART Accelerator (DMA2D) for 2D composition and Chrom-GRC (GFXMMU) for dynamic memory mapping, while the MIPI DSI Host supports two lanes at 500 Mbit/s each - enabling direct drive of high-speed display panels without external bridge ICs.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32L4R9ZGJ6 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, even when executing from dual-bank Flash memory.
Does this MCU support external memory expansion, and what interfaces are available?
Yes - it supports external memory via Flexible Static Memory Controller (FSMC) for NOR/PSRAM/SRAM/NAND/FRAM and two independent OctoSPI interfaces. Each OctoSPI supports XIP, memory-mapped mode, and dual-flash configurations, enabling up to 4 GB addressable external storage with hardware-accelerated access.
How does the power management system support ultra-low-power operation?
It integrates FlexPowerControl with three regulator options (LDO, SMPS, VBAT), five low-power modes, and hardware peripherals active in Stop/Standby - including 2.8 μA Stop 2 with RTC, 420 nA Standby with RTC, and 33 nA Shutdown with five wakeup pins. Brownout reset (BOR) operates in all modes except Shutdown.
What display interfaces does the STM32L4R9ZGJ6 natively support?
It natively supports both MIPI DSI Host (dual-lane, 500 Mbit/s per lane) and parallel LCD-TFT controller (24-bit RGB, up to 24 MHz pixel clock). No external bridge IC is required for DSI panels, and Chrom-ART Accelerator (DMA2D) + Chrom-GRC (GFXMMU) enable efficient GPU-like 2D composition and memory optimization.
