Frequently asked questions

Can I use the 47 I/O and dual SSP ports for a Profinet/RT Ethernet stack?

The LPC2138 does not carry an integrated EMAC (Ethernet MAC) — a Profinet/RT stack requires external PHY hardware and consumes significant CPU cycles on the SSP/SPI ports. The LPC2378, which includes a built-in EMAC, is better suited to Ethernet-connected designs. If your architecture uses a external PHY, confirm the SSP bus bandwidth and CPU headroom against your protocol stack load before committing the LPC2138 to that role.

How do I source this part for a Q4 panel build?
