We just finished routing our first attempt at an LPC1343 Reference Design (Cortex M3 core), and the boards should be back in two weeks time. We had originally planned on releasing an LPC1313 board, but the 1343 seems to be a much more appropriate choice in that it not only has USB 2.0 support (unlike the comparable LPC2103 in ARM7 or LPC1114 in Cortex M0 which we also have reference designs available for), but it has HID and Mass Storage support built right into the ROM. The main advantage of this isn't so much convenience (though that's a nice bonus), but that you're able to save valuable flash and SRAM since you don't have to add in your own USB stack. On a 32KB/8KB part, every byte makes a difference, and in this case you're probably saving at least 2-3KB!
The LPC1343 is very similar to the LPC1114, so there shouldn't be any surprises when we get the boards back, but we did make a number of changes based on our experience with the LPC1114. Solder jumpers were added to allow someone to physically disconnect the external crystal (to save power if you're only using the internal oscillator, or just want to be 100% sure you're NOT using the external crystal). We previously had physical 0.1" jumpers on the LPC1114 prototype, and it seemed wasteful to have the jumpers sticking up off the board when you're only likely to change their state once or twice anyway. Unlike the LPC1114 board -- which was designed to be battery powered -- the LPC1343 board can only be powered from either USB or a 2.0/2.1mm DC barrel. There is no step-up converter included on the board. We also decided to use only 0805 components (rather than the 0603 parts that we typically use) simply to make it a bit easier for someone to hand-populate the board or solder it by hand if required. Other than that, the main wiring on the board is very similar, and the 1343 seems to be more or less pin-compatible with the 1114.
Similar to the LPC1114 board, we've also included two (identically wired) SWD connectors: the standard ten pin 0.05" SMT connector, along with a larger 0.1" 10-pin Molex-type connector to allow you to more easily connect hardware debuggers that don't have the new 0.05" cable (currently Keil is the only company providing a hardware debugger with the new connectors on it). You can easily hook a Segger J-Link up to the board using some jumper wires, for example.
In any case, we"ll post an update once the boards are in, and will put the Eagle files and schematics up once we're convinced that the basic design is sound. It's a great time to be developping hardware, as feature sets go up, prices go down, and everything seems to get easier than it was before!
Update: A nice feature on the LPC1343 that's easy to miss at first glance is that it has a built in USB Bootloader as well as the classic UART-based ISP. When you boot the device into ISP mode (by setting P0.1 LOW after reset), the bootloader will check the state of pin 0.3. If P0.3 is HIGH, it will cause the LPC1343 to enumerate as a USB/MSC device and will appear as a filesystem on Windows/Linux PCs; If P0.3 is LOW, it will boot into the classic UART/ISP mode and you can update the device using FlashMagic. (For reference sake, we've designed the board to boot into USB mode when the ISP jumper is set and a USB cable is connected, but it will fall back to the the classic UART/ISP mode when a USB cable is not connected.)
