ARM Cortex-M4 at 120 MHz with a full peripheral set
The NXP LPC4088FET208,551 is a 32-bit ARM Cortex-M4 microcontroller running at 120 MHz, with 512 KB of Flash program memory and 96 KB of RAM. It is part of the LPC40xx series and targets applications that need a balance of processing throughput and peripheral integration — think industrial gateways, HMI panels with LCD support, and CAN-based machine control. The internal oscillator and brown-out detect/reset reduce external BOM count.
The 208-TFBGA (15x15 mm) is a fine-pitch BGA — board assembly requires a solder-paste stencil and reflow profile matched to the package; hand-soldering is impractical. The 165 I/O are distributed across the ball grid, so a 4-layer PCB with a solid ground plane is typical to route signals and maintain signal integrity on the Ethernet and USB differential pairs.
