Product details

Peripheral set — what connects where

This MCU carries CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, and UART/USART interfaces. That QSPI is useful for memory expansion without chewing up I/O pins — you can hang a serial NOR Flash for code shadowing or data logging. The SAI (serial audio interface) makes it a candidate for audio processing or voice-trigger applications.

Package and footprint — 100-LQFP

The 100-LQFP (14x14 mm) is a common, hand-solderable footprint — no hot-air station needed for rework, which matters if you are swapping this on a bench or in the field. The supplier device package is 100-LQFP (14x14). Surface-mount only; no through-hole option. The 82 I/O give you room for a parallel LCD, external memory bus, or a sensor array without a port expander.

Lifecycle — still in active production

STMicroelectronics lists the STM32L471VET6TR as Active. No NRND or EOL notice on this base number.

Frequently asked questions

Can STM32L471VET6TR be replaced by STM32L476VET6?

The STM32L476VET6 is a pin-compatible alternative within the same STM32L4 family, sharing the same 100-LQFP package and similar memory and peripheral set. The key difference is that the STM32L476 includes a full-speed USB OTG peripheral, while the STM32L471 does not. If your design does not require USB, the STM32L471VET6TR is a direct fit; if you need USB, the STM32L476VET6 is the closer match. Verify the specific peripheral list against your application before swapping.
