Do any of the LPC ARM's have faster SPI ports (like maybe with a FIFO), or are they all basically the same as LPC210X? I thought I saw mention here that one of them had a slightly faster SPI implementation, but I can't find any such part now.

Hi everyone, I wanted to fabricate a board with the LPC210x that will have USB connectivity. I have found some simple chips that would definitely do the job - for example PDIUSBD12 which is a USB interface device with parallel bus. However, I don't think I would be able to bootstrap

Okay, I'm trying to find out a way to program 13 different LPC2000 devices on the same jtag chain. We have one LPC2138, and twelve LPC2103's.

We'd prefer a windows based solution as that is what the techs have access to already. I a...

Hello friends! About a year ago someone saw here that Philips was about to release new versions od LPC2104-LPC2106 with CRP implemented. Someone has any news about it?

I'm using the 48 pin LPC2102 and I'm having difficulty configuring P0.17 and P0.18. I want to use these pins as a general purpose output to provide a high and low voltage without any pull ups, the problem is that on the board I'm using these pins appear only to be able to give me an open drain output. From the Pin Configuration section (Chapter 6) of the User Manual both P0.17 and P0.

Hi, I'm trying to do my first design using a LPC2103. I use a 14.75 MHz crystal with the params: Freq: 14.75.. MHz CL: (Load capacitance) = 10 pF Rs: (Max crystal resis.) = 200ohm According to the lpc210x user manual on page 17, I should use 18pf external capacitors (since resist. < 320ohm). Can anyone confirm that this is correct and I'm not making a stupid mistake? Thanks a lot
