Frequently asked questions
Is the 80-LQFP footprint drop-in compatible with the 100-pin LPC176x variants?
No — the 80-pin LPC1752FBD80,551 is not pin-compatible with any 100-pin LPC176x variant. They differ in pin count and pinout. A drop-in replacement requires matching the 80-pin LPC1752 footprint exactly.
Does this part need an external Ethernet PHY for fieldbus?
Yes — the LPC1752 does not carry an integrated Ethernet MAC. Any Ethernet-based fieldbus (Profinet, EtherNet/IP) requires an external PHY regardless of application. The on-die USB peripheral type (device/host/OTG) is not specified in the cited evidence and should be verified in the NXP datasheet for your USB role requirement.
