The LPC54606 comes (also) in a QFP100 package. It is shown in the datasheet that it supports 8/16 bit EMC interface. It has support for port 0 and port 1 so most of the EMC (for SDRAM) signals are there.
However, the EMC_A are only located on P3.25 which is not available on the 100 pin package. EMC_A and EMC_A are connected to BA0 and BA1 on a 16 bit SDRAM device. Is there some different connections to be used on the 100 pin package, or is it not possible to support 16 bit SDRAM on this package ?
