Product details
Overview
STM32L4S5VIT6 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 + LCD-TFT controller for embedded display applications. It delivers 150 DMIPS, supports -40 °C to 125 °C operation, and achieves 33 nA Shutdown mode current.
For engineers reviewing the STM32L4S5VIT6 datasheet, STM32L4S5VIT6 pinout, STM32L4S5VIT6 application, or STM32L4S5VIT6 equivalent, key selection criteria include ultra-low-power operation across multiple sleep modes, hardware-accelerated graphics (Chrom-ART/DMA2D), cryptographic acceleration (AES-256/HASH), and dual-bank read-while-write Flash for robust firmware updates.
Technical Context
The STM32L4S5VIT6 integrates an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz, and a multi-AHB interconnect matrix supporting concurrent access to Flash, SRAM, and peripherals. Its FlexPowerControl architecture enables dynamic voltage scaling and multiple low-power modes with sub-μA retention.
It features three PLLs - one for system clock, one for USB/SDMMC, and one for audio - plus internal clock sources including auto-trimmed 4–48 MHz and 32 kHz oscillators. The MIPI DSI Host controller supports two lanes at up to 500 Mbit/s each, directly driving display panels without external bridge ICs.

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 |
|---|---|---|---|
| STM32L4R9VIT6 | Same core, 2 MB Flash, but adds Chrom-GRC (GFXMMU) and higher SRAM (2 MB); no MIPI DSI | Targeted at high-resolution GUI with external SDRAM, not direct-panel MIPI DSI drive | Select when graphics memory bandwidth exceeds internal SRAM capacity and external DRAM is acceptable |
| STM32U575ZIT6 | Next-gen Cortex-M33, TrustZone, 1.5 MB Flash, 786 KB SRAM, lower active current (65 µA/MHz), no MIPI DSI | Designed for PSA Level 3 security certification; lacks integrated display interface | Select when hardware root-of-trust and PSA-certified secure boot are mandatory, and display is handled externally |
Compared with STM32L4R9VIT6, the STM32L4S5VIT6 offers native MIPI DSI for direct panel integration but less SRAM; versus STM32U575ZIT6, it trades PSA-certified security for proven display subsystem maturity and broader ecosystem tooling.
