The STM32L471RET6TR: The integrated CAN controller in the 64-LQFP package reduces BOM count. The 51 I/O lines handle a parallel display bus, keypad matrix, and sensor interrupts without a port expander.
The device comes in a 64-lead LQFP with a 10x10 mm body and 0.5 mm pitch.
Yes, the connectivity block includes a CANbus interface. This is an on-chip peripheral, so no external CAN controller is needed — just a CAN transceiver on the bus pins.
Within the STM32L4 series, the STM32L476 and STM32L496 families share the same 64-LQFP footprint and similar peripheral sets, though Flash and SRAM densities vary. For a direct drop-in with identical pinout, check the STM32L471xx family — the RET6 variant (512 KB Flash) is the same silicon. No official second-source alternate from another manufacturer is recorded for this base product number.
