STMicroelectronics STM32L496G-DISCO

Overview

STM32L496G-DISCO from STMicroelectronics is a full-featured discovery kit centered on the STM32L496AGI6 Arm® Cortex®-M4 microcontroller (1 MB Flash, 320 KB RAM, UFBGA169), integrated with a 1.54-inch 240×240 TFT LCD, SAI audio codec, stereo digital MEMS microphones, 8-Mbit PSRAM, and 64-Mbit Quad-SPI flash - designed for rapid prototyping of ultra-low-power graphics and audio applications.

For engineers reviewing the STM32L496G-DISCO datasheet, STM32L496G-DISCO pinout, STM32L496G-DISCO application, or STM32L496G-DISCO equivalent, key selection considerations include on-board ST-LINK/V2-1 debugger support (mass storage, VCP, debug), dual-supply capability (1.8 V / 3.3 V MCU operation), IDD measurement circuitry, and ARDUINO® Uno V3 and STMod+/Pmod™ expansion compatibility.

Technical Context

The board implements the STM32L496AGI6 as its core controller, leveraging the Chrom-ART Accelerator for efficient 2D graphics rendering and low-power peripherals including SAI for audio streaming, multiple ADCs, and flexible clock management with HSE/HSI/MSI/LSE sources. It supports USB OTG FS and USB Device modes via Micro-B and Micro-AB connectors.

Power architecture enables evaluation across three supply domains: ST-LINK VBUS, USB OTG FS VBUS, or external 5 V/3.3 V inputs, with selectable MCU voltage (1.8 V or 3.3 V) and dedicated current-sense resistor for real-time IDD monitoring - critical for battery-powered design validation.

FAQ

Does STM32L496G-DISCO support USB device mode without external hardware?

Yes - the board integrates native USB OTG FS functionality via the STM32L496AGI6's on-chip PHY and supports device mode using the USB Micro-B connector. The on-board ST-LINK/V2-1 also provides a separate USB interface for debugging and virtual COM port use, independent of target USB operation.

Can the on-board TFT display be driven directly by the MCU without external controllers?

Yes - the 240×240 RGB interface connects directly to the STM32L496AGI6's LTDC peripheral. The Chrom-ART Accelerator handles layer composition and blending in hardware, enabling smooth GUI rendering without CPU overhead or external display controllers.

Is the PSRAM accessible as executable memory (XIP)?

No - the 8-Mbit PSRAM is connected via the FSMC parallel interface and used for data storage only. XIP is supported only on the 64-Mbit Quad-SPI flash, which connects to the Octo-SPI peripheral and allows direct code execution from external memory.

What debug interfaces does the on-board ST-LINK/V2-1 provide?

The ST-LINK/V2-1 offers SWD (2-wire) and JTAG (4-wire) debug access to the target MCU, plus USB-based virtual COM port and mass storage programming - all accessible simultaneously without hardware reconfiguration or jumper settings.
