Frequently asked questions
Does the ROMless LPC3250FET296,551 require external flash to boot?
Yes — the part boots from external memory over the EBI/EMI bus. A companion external NOR or NAND flash device is mandatory on the BOM; the minimum qualified boot-memory device is documented in the NXP LPC3250 user manual, not the order-code ledger.
What supply voltage does this part need?
0.9 V to 3.6 V single rail. The wide range accommodates 3.3 V industrial logic directly, but at 266 MHz the dynamic current draw under full load at 85 °C ambient requires thermal management via the TFBGA bottom-pad land pattern and PCB ground-plane stitching.
