Product details

80 MHz Cortex-M4 with 1 MB Flash — memory headroom for field-upgradeable firmware

The STM32L476JGY6TR: The 57 general-purpose I/O lines connect to CANbus, I²C, SPI, Quad-SPI, SAI, USB OTG, and an LCD controller. Two 12-bit DACs and a 16-channel 12-bit ADC handle mixed-signal tasks.

72-WLCSP footprint — board area and rework considerations

Housed in a 72-ball WLCSP measuring 4.41 x 3.76 mm, this package saves significant PCB real estate compared to a QFP or BGA of the same pin count. The wafer-level chip-scale package requires a solder-paste stencil designed for the 0.4 mm pitch and a reflow profile that follows the JEDEC MSL level specified on the reel label. For rework, a hot-air nozzle matched to the package outline and a preheat soak at 125°C reduce the risk of adjacent component disturbance.

The ROHS3 compliance is current.

Frequently asked questions

What is the closest functional alternative to STM32L476JGY6TR?

The STM32L151CBU6A is a lower-cost, lower-performance sibling from the STM32L1 series: it runs a Cortex-M3 core at 32 MHz with 128 KB Flash, fewer I/O (37), and a narrower connectivity set (no CAN, no QSPI, no SAI). It is not a pin-compatible drop-in — the package and peripheral map differ — but it serves as a functional alternative for cost-sensitive designs that can trade down on speed and memory.
