Product details

What this Cortex-M4 brings to the board

It packs 1 MB of Flash and 128 KB of SRAM, with a rich peripheral set including USB OTG, CANbus, QSPI, and multiple serial interfaces.

1 MB Flash and 128 KB SRAM — sizing the firmware budget

With 1 MB of Flash, this MCU can hold a full sensor-fusion stack, a real-time OS, and an OTA update staging area without external memory. The 128 KB SRAM is enough for moderate-size data buffers and protocol stacks; if your application runs heavy graphics or large audio buffers, you will want to budget for external PSRAM or SDRAM via the QSPI interface.

Connectivity that covers the fieldbus landscape

The STM32L475RGT7TR includes USB OTG (host and device), CANbus for industrial or automotive networks, QSPI for high-speed external Flash/RAM, and SAI for I2S audio.

This is a current-production STM32L4 device, so the primary channel is franchised distribution. Independent stock also exists, typically from excess inventory buffers. If you need a reel for a pilot run or a tray for a prototype, let us know the quantity and we will check the open market and franchise back-channels.

Frequently asked questions

Is STM32L475RGT7TR RoHS compliant?

The STM32L475RGT7TR is listed as RoHS compliant by STMicroelectronics. The '7' in the order code typically indicates a green/lead-free package variant, and the datasheet confirms it meets the RoHS directive.

Can STM32L475RGT7TR be used as a replacement for STM32L475RGT6?

The STM32L475RGT7TR is a functional equivalent to the STM32L475RGT6, sharing the same core, memory, and peripheral set. The difference is in the packaging and shipping medium: the '7' suffix indicates a green/lead-free package variant, and the 'TR' suffix denotes Tape & Reel packaging. Pin-compatible and software-compatible, so it can replace the RGT6 on the same PCB.

Does STM32L475RGT7TR have built-in USB OTG?

Yes, the STM32L475RGT7TR includes USB OTG (On-The-Go) as part of its connectivity block, supporting both host and device modes. This is listed in the connectivity field of the specification.

What is the lead time for STM32L475RGT7TR?

Lead time varies with market conditions and order quantity. For current lead time and availability, submit an RFQ — we will confirm the lead time from our supply chain at the time of quoting.
