Product details
Overview
STM32L4R9ZIY6PTR 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, integrated LCD-TFT controller and MIPI DSI host interface, designed for high-resolution graphical HMI applications in battery-powered industrial and medical devices.
For engineers reviewing the STM32L4R9ZIY6PTR datasheet, STM32L4R9ZIY6PTR pinout, STM32L4R9ZIY6PTR application, or STM32L4R9ZIY6PTR equivalent, key selection criteria include ultra-low-power operation (420 nA Stop 2 with RTC), dual-bank Flash read-while-write capability, hardware-accelerated graphics (Chrom-ART DMA2D + GFXMMU), and MIPI DSI support up to 500 Mbit/s per lane.
Technical Context
This MCU implements an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, paired with a multi-AHB interconnect matrix for concurrent peripheral access. It integrates three PLLs - one for system clock, one for USB/audio, and one for ADC - supporting precise clock domain isolation.
The device features dual OctoSPI interfaces for external memory expansion, a 14-channel DMA controller with DMAMux routing, and independent analog supply domains for 12-bit 5 Msps ADC, dual 12-bit DACs, two op-amps with PGA, and two ultra-low-power comparators - all operating under flexible voltage scaling.

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 |
|---|---|---|---|
| STM32L4R5VIQ6 | Same core/peripherals but 1 MB Flash, 320 KB SRAM, UFBGA100 (100-pin); no MIPI DSI or LCD-TFT controller | Suitable for non-graphical applications requiring lower cost and smaller footprint | Select when display interface is unnecessary and memory requirements are halved |
| STM32U575ZIT6 | Arm Cortex-M33, TrustZone, 2 MB Flash, 1 MB SRAM, 1.5x higher ULPMark-CP (359), but no MIPI DSI or Chrom-ART | Better security and compute density; lacks dedicated graphics acceleration and display controllers | Prefer for secure firmware updates and cryptographic workloads where display is handled externally |
Compared with STM32L4R9ZIY6PTR, STM32L4R5VIQ6 trades graphics capability for compactness and cost, while STM32U575ZIT6 prioritizes security and efficiency over integrated display subsystems - making the L4R9 optimal for self-contained, battery-powered graphical HMIs.

FAQ
What is the maximum operating temperature range for STM32L4R9ZIY6PTR?
The STM32L4R9ZIY6PTR is qualified for industrial operation from –40 °C to +85 °C. Its thermal design supports sustained 120 MHz operation within this range when using the external SMPS supply and proper PCB thermal layout per AN5053 guidelines.
Does STM32L4R9ZIY6PTR support true hardware encryption?
No - it lacks dedicated cryptographic accelerators (AES, PKA, HASH). It includes a true random number generator (RNG) and 96-bit unique ID for key derivation, but AES operations require software implementation or external secure element integration.
Can the MIPI DSI interface drive a 1080p display?
Yes - with two DSI lanes running at 500 Mbit/s each (1 Gbit/s aggregate), it supports up to WUXGA (1920×1200) at 60 Hz using video mode, provided the external D-PHY PHY and panel timing meet JEDEC-standard electrical and protocol constraints.
Is external SMPS mandatory for ultra-low-power operation?
No - the integrated LDO supports full functionality, but external SMPS reduces active-mode current to 43 µA/MHz (vs. 110 µA/MHz with LDO), delivering up to 61% power savings in sustained processing - essential for multi-day battery life in portable designs.
