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."},{"question":"How do I source this part for a Q4 panel build?","answer":"Submit an RFQ with your required quantity, target date, and traceability requirement.
