Package and I/O for panel-mount integration
The LPC55S26JBD64K: The 64-HTQFP exposed pad package (10x10 mm) gives 36 general-purpose I/O plus the Flexcomm interfaces that can be reconfigured as I²C, SPI, UART, or I²S without changing the PCB. The exposed pad pulls heat into the ground plane — useful when the MCU drives a USB host or multiple PWM channels near the 105°C ceiling. Mounting is standard surface-mount; no special reflow profile beyond the usual lead-free recipe.
Sourcing note for BOM freeze
The active status means no supply discontinuity is expected, but as with any semiconductor, lead times can shift — an RFQ locks the allocation for your build window.
