The NXP LPC2478FET208,551 is a 16/32-bit ARM7-based microcontroller from the LPC2400 series, clocked at 72 MHz with 512 KB of on-chip Flash and 96 KB of SRAM. It targets mid-complexity embedded systems that need a single-chip host for a local display, a wired network stack, and multiple fieldbus connections — think HMI panels, industrial gateways, or building-automation controllers where the BOM must carry Ethernet, USB OTG, and CAN on one die without an external bridge chip.
72 MHz ARM7 — what the speed means for your design
At 72 MHz the ARM7 core delivers enough throughput for an RTOS, Ethernet stack, LCD refresh, and CAN messaging.
Package reality — 208-ball TFBGA
The 208-TFBGA (15x15 mm) demands a multi-layer PCB with microvia capability. Rework requires a BGA station.
The internal oscillator and brown-out detect help maintain reliable operation across the temperature span without an external supervisor in many designs.
