Just dropped in my mailbox this aft. Nothing available yet but the press
release.

Hi Robert, my apologies, did not realize that we had a publishing problem on our website. In the files section I just uploaded the Data Sheet. For the Users Manual it will probably take another week. Some highlights: One device with 32k Flash / 8k RAM (sounds familiar? ;-) One device with 512k Flash / 32k RAM probably does not sound familiar Single voltage supply 10-bit ADC with 8 or 16 inputs 10-bit DAC 32 kHz input and option to run Real Time Clock during Power down Counter inputs for 2 timers Brown-out detect. overall 47!! pins for I/O if all are used for that Embedded Trace Macrocell Improved SPI, called SSP Hope this made you curious.

Thanks for the data sheet, apologies certainly accepted but not really
needed. I'm used to press releases preceding the data sheets (Microchip in
particular seems to take years). Having the datasheet immediately
available is nice though.

Definitely, can I take it the SSP cures the race condition in the SPI? And
how about the race condition in the timers (that's actually more critical I
believe)?

Hi Could someone please tell something more about these race condition ? Both SPI and Timers Could it not be avoided ? best regards John

The SPI race condition is explained in the errata sheets, the timer issues
is not officially documented in an errata yet but an explanation is
contained in a file in the files section
http://groups.yahoo.com/group/lpc2000/files/Timer_issue.pdf
The basic problem in both cases is the same. If a register is read at the
same time as the underlying HW attempts to update it the update gets 'lost'

This is simply an amazing device. It has everything that I have been asking for in a micro (well I would have liked more RAM, ala the LPC2106). However the built in 1.8V reg, battery powered RTC, A/D and D/A are amazing. Thanks Philips - you once again made my life a little easier (and more enjoyable!). I noticed that the data sheet you uploaded to the yahoo files section and the one on the Philips site differ in size yet the version appears to be the same - can you specify any differences, if any, between these two files? I am meeting with Arrow (our Philips distributor) next Wednesday. They promised more information on this part (specifically the LPC2138). I am hoping to get a user manual and a complete data sheet, and of course pricing and availability. Is there a possibility to get either of these documents from Philips directly, before then? The sooner I get this information the sooner I can start getting boards made and firmware written.

Hi, sorry for the confusion about file size of the Data Sheet. This is simply because of compression difference in the Adobe Acrobat. The posted file on the Yahoo Group was last handled in the team who writes the Data Sheets after knowing it is released, the other document on the website got the final touch by our publishing team in the Netherlands. The data sheet is the same! Thanks for the compliments, tried to implement as much as possible from the feedback we got during the poll in summer. btw. Users Manual will probably take another week or two. Best regards, Robert --- In lpc2000@yahoogroups.com, "R M" <rodlist@r...> wrote:

And an errata sheet? With the new POR, can you just tie /RESET to VDD? The Aug 25 manual says that the boot loader uses 12 KB in the LPC2138, leaving 500 KB for the user, but in the LPC2132 it uses 0 KB. Does the LPC2132 (and LPC2131) have an extra secret 12 KB flash or ROM, or is there really only 20KB/52KB left in the LPC2131/32? Or is there no boot loader at all? How large is the SSP FIFO? And can SSPCR0.DSS (data size) be set to any size between 4 and 16 bits, or are only 4, 8, and 16 allowed? (And why didn't you change both SPI controllers to SSP? The master /SSEL "feature" is apparently only fixed in the SSP?) Karl Olsen

Hi Karl, the User's Manual has been posted in the file section (by John). The 2132 and 2131 have an extra Flash area for the boot loader. 64k / 32k are all available to the user. SSP Fifo 16 messages (see UM), data length any value between 4-bit and 16-bit. Why not changed both SPI to SSP, legacy / compatibility. The old SPI let's you switch between master and slave mode on the fly, the SSP sort of does not. This feature is not typical in SPI usage but.. some people might use / want it. Hope these answers help. Robert --- In lpc2000@yahoogroups.com, "Karl Olsen" <kro@p...> wrote:

Robert, Do you know if there are any plans on adding USB to the LPC parts? USB host? USB device?

Hi In 2005 Philips will release LPC214x, which is LPC213x + USB. I think it will be USB device, but who knows ? See Philips Roadmap 2004-2005 in files section. It looks good. Best regards John Noergaard --- In lpc2000@yahoogroups.com, "Gus" <gus_is_working@y...> wrote:

The POR isn't very well explained. Can the chip boot correctly with /RESET tied to VDD, regardless of the VCC ramp? And can the ISP erase/program functions be expected to work correctly as long as POR and BOD don't reset the processor? The datasheet says that Vbat min = 3.0V. Can I expect it to work reliably with a 3V lithium battery? In addition, are you planning to update the LPC2000 Flash Utility to support LPC213x? I have some LPC2132 samples and will soon have to convert some LPC2114 projects to LPC2132. And may I suggest an option to please get rid of the splash screen at startup? Thanks, Karl Olsen

Don't know the characteristics of a lithium battery in regards to stability of voltage but the brownout should help you if the voltage goes below 3V. There will be no undefined operation before the brownout hits even if voltage goes below 3V but is still above brownout threshold. > > In addition, are you planning to update the LPC2000 Flash Utility to > support LPC213x?

Hi Gus, the answer to your two questions USB host? USB device? is Yes. First the device on the LPC2140 series but we are also working on a host option for 2nd half of the year. And oops the Fifo for the SSP is 16 messages but it is 8 for receive and 8 for sending. Robert --- In lpc2000@yahoogroups.com, "Gus" <gus_is_working@y...> wrote:
