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.","metaTitle":"STM32L471VET6TR STMicroelectronics ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STM32L471VET6TR is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics, 80 MHz, 512 KB Flash, 128 KB SRAM, 100-LQFP, -40°C to 85°C.

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.
