Product details

72 MHz ARM7 — what the core speed buys you

The LPC2367FBD100,551: 72 MHz is the practical ceiling for this ARM7 pipeline without cache. The DMA peripheral offloads ADC result transfers and memory-card block reads.

512 KB Flash / 58 KB RAM — firmware and data budget

The 512 KB Flash holds a full TCP/IP stack plus the application image. 58 KB of SRAM is enough for two Ethernet frames and the RTOS task stacks.

NXP has marked this part Not Recommended for New Designs (NRND). That means the manufacturing line is still running, but the window for last-time-buy and final shipments is finite.

Frequently asked questions

Is LPC2367FBD100,551 obsolete?

NXP has classified this part as Not Recommended for New Designs (NRND). It is not formally discontinued, but it is on a path to end-of-life. For new projects, choose the pin-compatible LPC2368FBD100 or LPC2378FBD100 instead.

What is the exact replacement for LPC2367FBD100,551?

The closest pin-compatible replacement with more memory is the LPC2368FBD100 (512 KB Flash, 58 KB RAM — same as this, but with additional Ethernet buffer support) or the LPC2378FBD100 (512 KB Flash, 98 KB RAM). Both drop into the same 100-LQFP layout.

Does LPC2367FBD100 have a built-in Ethernet controller?

Yes, it integrates a 10/100 Ethernet MAC with dedicated DMA and an MII/RMII interface. You still need an external PHY chip (e.g., DP83848) and magnetics to complete the physical layer.

How does LPC2367FBD100 compare to LPC2368FBD100?

Both have 512 KB Flash and 58 KB RAM. The LPC2368 adds an extra Ethernet buffer and a few more peripheral features; functionally they share the same core, package, and pinout. The LPC2368 is the recommended upgrade for new designs.
