Lpc2000

I am working on a design that uses an LPC2212 and need to have power 
consumption minimized. According to the datasheet, the 1.8V draws 
~10uA in sleep mode, but I'm seeing 40uA. The EVBA7 comes in at 5uA 
using same code. And worse, I'm not able to get the 3.3V draw under 
1.2mA(EVBA7 is 200uA.) It needs to be pretty much nil. I have turned 
off all peripheral power using  REG(SYSCON_PCONP) = 0x00000000; I 
have been able to reduce the 3.3V draw from 3.5mA by turning off the 
external memory controller and disconnecting the memory bus and 
debug port using PINSEL2. I've tried to set all peripheral functions 
to GPIO.  I don't think I'm driving anything else on the board with 
3.3V. I've pulled practically every load to check, but no dice. 
Any thoughts/ideas?
Thx
