The 64-LQFP package (10x10 mm) is a standard low-profile quad flat pack with a 0.5 mm pitch — rework-friendly under hot air, with a visible pin 1 chamfer that helps alignment during hand reflow.

Frequently asked questions
What is the closest functional alternative to STM32L471RET6?
The STM32L151CBU6A shares the same 12-bit ADC/DAC resolution and 1.8 V supply range but lacks the CANbus, QSPI, and SAI interfaces. It is not pin-compatible — the STM32L151CBU6A comes in a 48-pin package — so a board redesign is required.
