STM32L476RGT6 — 80 MHz Cortex-M4 with 1 MB Flash in 64-LQFP
The 64-LQFP package (10x10 mm body) provides 51 I/O lines, making it a dense but hand-solderable option for production and prototyping alike.
Peripheral set — CAN, USB OTG, QSPI, and more
Connectivity includes CANbus, USB OTG, QSPI, SAI audio, and multiple I²C/SPI/UART interfaces. The QSPI interface is useful for memory-mapped external Flash or PSRAM expansion without consuming parallel bus pins. On-chip data converters provide 16-channel 12-bit ADC and two 12-bit DAC channels, sufficient for sensor acquisition and analog output loops without an external converter.
Lifecycle — active, no obsolescence concern
The base product number is STM32L476, and the STM32L4 series remains a mainstream ST portfolio family.
