  Ashling's answer is incomplete. From the 'Flash security' thread just a 
  little while ago.

  "Hello Armando,

  Richard is right, The LPC2104 / 2105 and 2106 do not support code read
  protection. Somebody with a JTAG debugger can go in an read your code.
  All other devices of the LPC2000-family do support code read protection.

  Application Support Philips"

With no internal flash there is nothing to protect.  The point is moot.

Protecting external flash would require some sort of encrypted bus.
