Opinions about the NXP LPC3000

Michael · 2007-04-25T06:56:07+00:00

Hi there - I've been eying the NXP LPC3000 series for a while now, asit's an ARM9 with both an FPU and an MMU (though no CAN, annoyinglyenough), but never bit the bullet as the BGA package always scared meoff. Well - I've finally developed a technique for soldering BGAs, soI think it's time I play with one of these buggers.Anyways - what do you all think of these parts? Also, is there anycompiler support for the FPU yet? It's a new chip so I'm a bitworried. I looked at the Cirrus EP-9302 a while back but from what Iread, compiler support for it's FPU was seriously lacking.Also - what is your general opinion about NXP? I've only worked withAtmel - who has (for the most part) been very helpful. NXP has a godawful website - so I guess it makes me worried about the rest of thecompany.Thanks!-Michael

The information did not come from a competitor.

DSP,

the right website.

atmelroma.it seems to just redirect to Atmel.com. I will ask my FAE about it. This lack of information online is pretty worrisome though. Seems like a nice chip - but I would prefer to stick with IAR, which doesn't seem to be a possibility.

According to Atmel there is:

(and many, many other documents)

What I've heard is higher clock speed, faster ADCs, DACs, interrupt priority levels, and most importantly to me, DMA. Are you saying you don't know anything about them, or can't say anything about them?

Thanks,

mid 2007 introduction for the Xmega's I heard, so maybe that translates into end of 2007 and samples next year, with production mid

2008 (i.e., available at digikey)

The dip modules from netburner are failry cheap US$40 dev kit is reasonable

Also avr32 from atmel

See if you can use one of the network development boards good for US$69. Atmel provides avr32gcc for windows and linux + ide(eclipse)

Keep an eye on the blackfin handy board project. Boards are supposed to be available soon. analog devices blackfin processor at 600MHz + 64MB ram and 256MB flash

xilinx s3 fpga for io blackfin is a fixed point dsp
