Product details
Overview
STM32L486RGT7 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 1 MB flash, 128 KB SRAM, USB OTG FS, LCD controller, and hardware AES encryption. It operates from 1.71–3.6 V across –40 °C to 105 °C, achieves 100 DMIPS at 80 MHz, and delivers 39 µA/MHz in SMPS mode-enabling battery-powered industrial sensors with local display and secure firmware updates.
For engineers reviewing the STM32L486RGT7 datasheet, STM32L486RGT7 pinout, STM32L486RGT7 application, or STM32L486RGT7 equivalent, key selection criteria include its dual-voltage I/O capability (down to 1.08 V), integrated LCD driver supporting 8×40 segments, low-power timer availability in Stop 2 mode, and verified CAN 2.0B + SDMMC interface coexistence.
Technical Context
This MCU integrates an Adaptive Real-time Accelerator (ART™) enabling zero-wait-state execution from flash at 80 MHz, alongside three independent PLLs for system, USB, and audio clock domains. Its interconnect matrix decouples bus arbitration between CPU, DMA, and peripherals-critical for deterministic real-time response in concurrent LCD refresh and sensor acquisition.
The FlexPowerControl architecture supports seven low-power modes, including Stop 2 with 1.1 µA consumption and 45 µs wakeup, plus dedicated low-power timers and LPUART that remain active during deep sleep. The 128 KB SRAM includes 32 KB with hardware parity, and external memory support spans SRAM, PSRAM, NOR, and NAND via FSMC.

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 |
|---|---|---|---|
| STM32L476RGT6 | Same LQFP64 package, 1 MB flash, but lacks USB OTG FS and LCD controller; 12-bit ADC only (no hardware oversampling) | Suitable for non-display, non-USB sensor nodes where cost optimization outweighs LCD/USB need | Select when USB/LCD functionality is unnecessary and BOM cost reduction is prioritized over feature headroom |
| STM32U575ZIT6 | Higher security (PUF, secure boot), 2.5x lower active power (18 µA/MHz), but no LCD controller and requires QFN/WLCSP packaging | Better for cloud-connected devices needing PSA Level 3 certification, but incompatible with existing LCD-based designs | Choose for next-gen secure IoT endpoints where display is handled externally and footprint flexibility exists |
Compared with STM32L476RGT6, the STM32L486RGT7 adds essential display and USB connectivity at modest power cost; versus STM32U575ZIT6, it trades advanced security for proven LCD integration and LQFP64 compatibility-making it optimal for cost-sensitive, display-centric industrial edge devices.

FAQ
What is the maximum operating temperature rating for STM32L486RGT7?
The STM32L486RGT7 is qualified for operation from –40 °C to +105 °C ambient temperature. This extended range is validated per ST's industrial-grade qualification standards and supports deployment in enclosed industrial enclosures or outdoor metering housings without forced cooling.
Does STM32L486RGT7 support external SMPS control?
Yes-it includes dedicated control signals (VDD12, VDD12_IO, VDD12_USB) and register-mapped SMPS enable/disable logic. The MCU can directly manage an external DC-DC converter to achieve 39 µA/MHz run-mode efficiency, with automatic voltage scaling coordination during low-power transitions.
Can the LCD controller drive segment-based e-paper displays?
No-the integrated LCD controller is designed exclusively for passive segment-based LCDs (e.g., 8×40 or 4×44) with AC bias requirements. It lacks the programmable waveform generator, charge pump voltage range, or grayscale timing needed for e-paper; external display controllers are required for EPD integration.
How many DMA channels are available and what peripherals do they support?
The STM32L486RGT7 provides 14-channel DMA controller with hardware handshaking. It supports all major peripherals including ADC, DAC, SPI, I²C, USART, USB OTG FS, SDMMC, and QUADSPI-enabling concurrent data transfers without CPU intervention, critical for real-time sensor fusion and display buffering.
