Product details

STM32L476JEY6TR — ultra-low-power Cortex-M4 with 80 MHz and 512 KB Flash

The 72-WLCSP package (4.41 x 3.76 mm) saves board area but demands careful PCB layout for the fine-pitch ball array. Connectivity includes CANbus, I²C, SPI, UART/USART, USB OTG, QSPI, and SAI — enough for sensor hubs, motor-control interfaces, or human-machine-interface panels. The 57 I/O lines and the integrated LCD driver expand the application space to segmented displays and keypads.

72-WLCSP — footprint and layout considerations

The 72-WLCSP package (4.41 x 3.76 mm) requires a via-in-pad or microvia process to route the 57 I/O and supply balls.

Frequently asked questions

What is the core processor of STM32L476JEY6TR?

It uses an ARM Cortex-M4 core, 32-bit single-core, running at 80 MHz.

Does STM32L476JEY6TR have an equivalent or replacement?

The STM32L151CBU6A is a functional alternative from the STM32L1 series, but it uses a Cortex-M3 at 32 MHz with fewer I/O and less Flash. It is not pin-compatible — the package and footprint differ. For a direct second source within the STM32L4 family, consider other STM32L476 variants in compatible packages.
