Frequently asked questions
What replaces the LPC2917FBD144?
There is no NXP-designated drop-in successor. The nearest same-package peer is the LPC2930 (192KB SRAM, 8-channel ADC, 144-LQFP), but it is not I/O-map compatible and is itself in the NXP end-of-life pipeline. A full migration requires a Cortex-M based NXP part and a board respin — the ARM9 register set is architecturally incompatible with Cortex-M.
We're line-down on an LPC2910 board — can we drop in the LPC2917FBD144?
No — the LPC2917FBD144 uses a different base product number (LPC2917 vs LPC2910), different I/O map, and different memory configuration (512KB Flash / 80KB SRAM vs the LPC2910 variant). A direct swap requires a board respin. For a 25-unit emergency build, RFQ the independent-distributor channel now while beginning the layout validation for the replacement part.
Does the LPC2917FBD144 support Profinet natively?
No — the onboard connectivity is CANbus, LINbus, SPI, and UART/USART. Profinet requires a dedicated protocol controller IC and firmware stack; the LPC2917 has neither. A retrofit using TIA Portal V17 with Profinet IO needs a gateway IC (e.g., Anybus or Hilscher module) between the CANbus or UART segment and the Profinet network, or a full redesign to a Cortex-M based part with an integrated Profinet stack.
