The interesting new Philips LPC2104 ARM chips (60 MHz, 44 pins) are now available. Eurodis (UK) has a tray of 250 in stock at 5.56 GBP each.
I hope to have a couple of samples shortly.
Philips has just released a Windoze ISP utility for programming them via a serial port, all that is needed on the target board is an RS-232 level converter.
