Hello,
I am using P89LPC 930 for my Design. But now I have one question:
Which ISP circuit should I take for my design? Are the two circuits listed in the home page are both OK? I notice that in their guide they both concerns with the 920 series. Now I wonder if there are any changes should I take for my design?

The 920 and upwards can be programmed by ISP (In-System-Programming) via UART and serial port of PC... and Flashmagic s/w.
All new LPC900 parts 8pin ~ 44pin can be programmed by ICP (but ICP bridge circuit is needed)
Page 5 shows the keil development board circuit (www.keil.com/mcb900).
If you want less problems then I would purchase a Keil board...as the hardware and limited programming software is supplied....... and will allow you to "kick start" your 1st design.... you can purchase from Keil or www.LPCtools.com.
From then..... if you build your own programmer .... and it doesn't work... you can always double check with the MCB900 board.
Regards
Joseph
