Product details

80 MHz Cortex-M4 with 256 KB Flash — mid-range industrial MCU

The 64-LQFP package gives 51 usable I/O, which is a practical count for a sensor hub or motor-drive interface without wasting board area on a larger QFP.

Industrial temperature range and peripheral set

The peripheral list includes CANbus, USB OTG, QSPI, and multiple I²C/SPI/UART interfaces, so it can serve as a fieldbus gateway node or a data concentrator bridging CAN to a USB host.

That means no last-time-buy clock is running, and the part is still being manufactured in volume by ST. The base product number is STM32L475, so any errata or application notes under that family apply directly.

The brown-out detect and reset peripheral is built in, so an external supervisor is optional.

Frequently asked questions

What is the flash memory size of STM32L475RCT7?

This is paired with 128 KB of SRAM.

Does STM32L475RCT7 have USB OTG support?

Yes, USB OTG is listed in the connectivity block alongside CANbus, I²C, SPI, QSPI, SAI, and UART/USART interfaces.

What is the difference between STM32L475RCT7 and STM32L476RCT6?

The STM32L476RCT6 is a close sibling in the same L4 family with the same 256 KB Flash and 64-LQFP package. The main difference is that the L476 includes a hardware cryptographic accelerator and a true random number generator, which the L475 lacks. If your application does not need on-chip AES or RNG, the L475 is a cost-effective drop-in alternative — pin-compatible and software-compatible for most peripheral code.
