HI Guys, I've ordered a few LPC4337 LQFP 144pin MCU's and I'm going to create my own breakout board.

The only thing I'm not too sure of is the JTAG programming port.
Can someone direct me to a circuit which has the LPC4337 with a JTAG programming port.

I've researched and come up with this. Let me know if this is wrong.

JTAG 10PIN programming port to LPC4337 LQFP144pin.

JTAG PIN 1 - +3V3
JTAG PIN 2 - JTAG_TMS with 10k pullup.
JTAG PIN 3 - GND
JTAG PIN 4 - JTAG_TCK with 10k pulldown.
JTAG PIN 5 - GND
JTAG PIN 6 - JTAG_TDO with 10k pulldown.
JTAG PIN 7 - JTAG_RTCK
JTAG PIN 8 - JTAG_TDI with 10k pullup.
JTAG PIN 9 - GND
JTAG PIN10- RESET_IN

Thanks guys and thank you for your recent support. Migrating from Atmel 32Bit to LPC is quite a challenge, but I'm getting there :)

Pete :)

Hey Pete,
are you going to make it available to others or even sell one or two PCBs (unpopulated) ?

Will you design it in a way, that allows use of the UART ISP option? This requires generating the uC's /RESET with a common-anode diode array, to implement a logic AND. And please omit the MAX3232, stick to the 3.3V levels ;-)
