Product details
Overview
STM32L4R7ZIT6 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 STM32L4R7ZIT6 datasheet, STM32L4R7ZIT6 pinout, STM32L4R7ZIT6 application, or STM32L4R7ZIT6 equivalent, key selection criteria include its dual-bank read-while-write Flash, Chrom-ART Accelerator (DMA2D), 24-channel capacitive touch sensing, and hardware parity-protected SRAM - all critical for safety-aware, graphics-intensive embedded systems.
Technical Context
This MCU integrates an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, and features a multi-AHB interconnect matrix for concurrent peripheral access without bus contention. Its power architecture includes three low-power modes (Stop 2, Standby with RTC, Shutdown) with sub-100 nA quiescent current and 5 µs wakeup latency.
The device embeds two independent analog domains: 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 supported by dedicated voltage regulators and independent supply pins.

FAQ
What is the maximum operating frequency and corresponding performance metric?
The STM32L4R7ZIT6 operates at up to 120 MHz with an ART Accelerator enabled, delivering 150 DMIPS (1.25 DMIPS/MHz) and 409.20 CoreMark® (3.41 CoreMark/MHz). This performance level supports real-time audio processing, sensor fusion, and dynamic GUI rendering without external co-processors.
Does this MCU support external memory expansion, and what interfaces are available?
Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, NAND, and FRAM, plus two OctoSPI interfaces for high-speed serial flash or RAM. These enable XIP execution, firmware overlays, and external frame buffer storage - essential for memory-constrained display applications.
How does the power architecture support battery longevity in portable designs?
It offers multiple ultra-low-power modes: 33 nA Shutdown, 125 nA Standby (with 5 wakeup pins), 420 nA Standby with RTC, and 2.8 µA Stop 2 with RTC. Combined with 43 µA/MHz SMPS-run efficiency and 5 µs wakeup, it achieves multi-year operation on small Li-ion or coin cells in intermittent-use devices.
Is hardware cryptographic acceleration included, and which algorithms are supported?
Yes - it includes dedicated hardware engines for AES-128/192/256 encryption/decryption, SHA-256 hashing, and Public Key Acceleration (PKA) supporting RSA and ECC operations. These accelerate secure boot, TLS 1.2/1.3 handshakes, and firmware signature verification without CPU overhead.
