I am curious about which of the LPC2xxx parts are available in automotive temps? I don't see that easily in the selection guide I found at NXP.com. I have a requirement for a low power MCU which I expect I can meet with one of the LPC2xxx parts, but I need a very small package like the QFN64 and it has to deal with storage temps down to -55C. The data sheet for the LPC2132 says it is o...

Hello; I am seeing some rumors(?) that there may be an LPC2xxx variant that supports USB. Is this real? or vapour-ware? If real? when will this variant be available in production quantities? I am interested in an LPC2xxx device that supports USB-2. I am considering an arm embedded project that needs USB, and it would be very nice to have a

The earlier LPC2xxx ARM processors require a bootloader update in order to protect the code from being read through ISP. We created a free update tool that is suited to reprogram any number of LPC2xxx microprocessors quickly and fool proof. The update tool provided by Philips works just fine, but only for engineers and the update job is quite tedious.

ok... I know that there are some Philips representatives out there. So I am posting this to this forum. I want to see an LPC2xxx part that is somewhat of a hybrid between LPC21xx and LPC22xx. - PQFP-64 package, (very important!) - Only lower 10 address lines, however 8 is also acceptable here - Four chip selects with OE, RD/WR, BLS0/BL

There's been a few posts recently asking about high-bandwidth I/O on the LPC2xxx parts (and I realise high is a relative term here). For what it's worth, here are some hard figures (from memory, so might not be 100% acurate!), based on a system we did a while back. I can't say too much about the application as it's covered by NDA (it was a type of sensor), but the characteristics of...

Most of my microcontroller experience has been with PICs and some other 8-bit microcontrollers. I want to start moving out to 32-bit, and the LPC2xxx series seems to be the best way to begin, as there appears to be a decent amount of support (at least in the hobbyist community). However, I've been a bit confused with how to start out. Model: Which LPC2xxx has enough peripherals to be a ...

With the rising interest in Forth, we have decided to make a demo system for Philips LPC2xxx CPUs. I had a couple of hours spare today, so a first cut is now available. You need 64k Flash, 16k RAM and a 10, 12, or 14.7 MHz crystal and a terminal emulator at 115200 baud. The distribution includes multitasking, floating point and a manual! http://www.mpeforth.com/arena/lpcforth.zip P...
