Frequently asked questions
Is the 80-LQFP footprint of the LPC1758FBD80K compatible with existing 175x designs in our panel?
The 80-pin, 0.5mm-pitch LQFP (12x12mm) package maps to the standard LPC175x pinout. Verify corner power/ground assignments against your existing layout before assuming drop-in compatibility — some early 175x designs routed signals to corner pins that changed function on the FBD80 variant. The 52 I/O count is the spec to cross-check against your current board's I/O map.
Does the 512KB Flash and 64KB RAM of the LPC1758FBD80K support migration from a legacy 1756 controller without bank-switching?
512KB program Flash handles most legacy codebases without bank-switching. Confirm your compiled.bin against actual Flash consumption — drivers and communication stacks consume more room than the base application. RAM at 64KB covers most real-time data and buffer needs at this performance tier.
What debug interface does the LPC1758FBD80K use?
ARM SWD and JTAG are both supported. The NXP LPC-Link2 probe is compatible with the standard ARM toolchain — Keil MDK, IAR EWARM, and MCUXpresso IDE all support SWD debug and production flashing via this probe.
