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.","metaTitle":"NXP LPC2478FET208,551 ARM7 MCU, 72 MHz, 512 KB Flash, 208-TFBGA","metaDescription":"NXP LPC2478FET208,551 ARM7 MCU, 72 MHz, 512 KB Flash, 96 KB RAM, Ethernet/USB OTG/CAN.
