Electronic – standard In Circuit programming connector for LPC chips


The various LPC microcontroller chips have a boot mode that accepts serial communication and writes the received program to Flash. I want to make a PCB with and LPC1114 that must be programmed in circuit, with only minimal interface circuitry on the PCB. Is there a standard connector for supplying the required signals (GND, RxD, TxD, Reset, BootModeEnable)?

I use Sparkfun's USB to UART board. I bring out UART0, reset and isp to headers. I connect reset and isp to ground with jumpers, then use FlashMagic. This only seems to work right if I also power the device from USB, so the grounds are common.
