Product details

The 109 I/O lines in a 144-LQFP package suit designs that need parallel display interfaces or multiple sensor inputs — think industrial gateways, battery-powered data loggers, or mid-complexity motor-control panels.

Connectivity and peripherals

On the peripheral side, the MCU includes CANbus, I²C, SPI, UART/USART, QSPI, SAI, and SWPMI — enough wired interfaces to handle sensor fusion, display communication, and fieldbus bridging without external transceivers (except for CAN).

Package and mounting

Housed in a 144-LQFP (20x20 mm) with surface-mount termination, this is a standard fine-pitch QFP that reflows on a typical lead-free profile.

Lifecycle and sourcing posture

This is a standard catalog part from ST, available through the usual authorized channels.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L471ZET6TR?

Within the STM32L4 series, the STM32L476ZET6 shares the same 144-LQFP footprint and pinout, but offers a different peripheral set (e.g., additional USARTs). Check the STM32L4 reference manual for the exact peripheral mapping before substituting.
