The NXP LPC3141FET180,551 is an ARM926EJ-S application processor from the LPC3100 series, clocked at 270MHz and built on a 16/32-bit core. It integrates a LCD controller, USB OTG, I²S audio interface, and a 4-channel 10-bit ADC — making it a fit for portable media players, handheld terminals, and industrial HMIs that need a single-chip display and connectivity solution. The part is ROMless, so all code runs from external memory via the EBI/EMI interface.
The 180-TFBGA (12x12 mm) package is a fine-pitch BGA. Surface-mount only; no socket option for this footprint.
