Product details

150 MHz Cortex-M3 with dual industrial networking

The 150 MHz core speed determines the real-time loop closure rate for motor drives and the packet-per-second throughput on the Ethernet port.

Memory sizing for firmware and buffers

512 KB Flash accommodates a full Ethernet TCP/IP stack plus a CANopen or Modbus TCP application image, with room left for a small bootloader and OTA staging area. The 136K x 8 RAM (roughly 136 KB) is the working memory ceiling — enough for two full Ethernet frames (jumbo-sized) and a few hundred CAN message objects, but tight if you plan to run a heavy GUI or large audio buffers without external SDRAM.

Industrial temperature range and package constraints

The 256-LBGA (17x17 mm) package requires a multilayer PCB with blind/buried vias for signal breakout.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1833FET256,551 in the LPC18xx family?

Within the LPC18xx series, pin-compatible density options exist — for example, the LPC1837FET256 with 1 MB Flash and 136 KB RAM shares the same 256-LBGA footprint. Verify the exact memory and peripheral set against your firmware image before substituting.

What compliance documentation does NXP provide for LPC1833FET256,551?

NXP provides RoHS and REACH compliance declarations for the LPC1833FET256,551. UL and IEC certification documentation is available through the standard datasheet package and NXP's document portal.
