Hi everyone,
We intend to buy a LPC2378 and I have sent several inquiries to their
technical support a few weeks ago from their web site but I have never
received any reply. The automatic confirmation came but the answer.
I have worked by the past with other companies in the same branch that
had a really efficient,fast tech support, I wonder what happens with
NXP. Looking at the range of microcontrollers they offer I was
expecting a great customer support but I am disappointed.
I start to wonder if we are not going to buy from another company.
Does anyone know how to get in contact with them?

Best regards
Fabrice Lucas

Hmm, normally you do not send inquiry to the technical support
team for sales related items. You can ask for the NXP representatives
or distributors. So far we deal with Arrow Electronics. Only for
technical matters that Arrow FAEs can not answer we will talk
to NXP FAEs.

I have never managed to get a reply from their web site technical
support form either. Complete waste of time.
The only way to get a reply seems to be to go through a distributor -
and even then it's hard work.

However, in my experience other manufacturers are no better. It very
much depends on how keen the distributor is, some are great and will try
really hard to get an answer out of the manufacturer. Others just can't
be bothered.

Some are very good: Microchip and ADI spring to mind, as well as startup
XMOS.

Indeed both are very good and very responsive. We go direct with both
so we do not need to go through distributors.

I've had replies within a day or 2 to all the 3 or so queries I've sent, but I think these
were all issues on clarifications/errors in the documentation - I don't think they've ever been
fixed though. Hard to tell as it can be hard to find latest versions of UMs etc, on NXP's website -
searches tend to find obsolete versions

(You need to be a member of lpc2000 -- send a blank email to lpc2000-subscribe@yahoogroups.com )

Well, I had similar situatuion: send inquires to NXP support.
Yes, they do reply. It takes a while, in my case it was less that 2 weeks.
Once they redirect you to an application engineer (they provide you with a
specific email),
email flow becomes quick.
The hard part is to pass the initial screening they have, which depends on
your problem,
and chip. You know, it seems there are some issues that are more relevant
that others.

There are actually two sites:

hi,

You can buy a development board, and it should support a FAE to you.

If there is any issue FAE can not resolve , he will refer to NXP

technology support.

Hi again,
I have been on www.nxp.com and www.standardics.com but both end up on
http://www.nxp.com/support/form.php when you ask for a support
inquiry. There is some litterature on both sites but I think an
efficient tech support can save you a lot of time and is a key factor
to complete a project on time. I guess I was just lucky with my
experience with other companies.
We will eventually buy a developpment board from IAR and hope they can
help. Anybody has any feedback about their support team?

Thanks everyone

That is not different from Futurlec with their LPC-2119. Their e-mail addresses are either full (both techsupport and webmaster!) or don't answer when the mail does not have the word "PURCHASE ORDER" in it. The phone numbers on their web-site are in reality all faxes, but sending a fax also results in no reaction at all. Oh well, one needs only one time an experience like this to know what to do next time.

Sorry to be banging on about XMOS again, but their customer support
is superb! Queries on their user forum get answered by their
engineers in a few minutes, and when I've phoned them I've been put
through to someone who can help, or they ring me back.

I think this is more a case of XMOS not being that big at present. I guess
things will slow when they inevitably take over the world. Personal
opinion. Flame me, I'm English and we revel in the delights of mid-day sun
on our pale flesh. :-)

Do any of you get the EETimes publication?? Issue 1542 Monday Sept 22, 2008
There was an article on whether NXP will survive the next round of
restructuring (4,500 job cuts in manufacturing as well as the head office)
Maybe some of the job cuts are Tech support/ Chip manufacture?!?!?! You

That is an interesting one. Mchip want to sell off the ASIC division to On

Richard and all,=20

it is way too early to tell whether MCHP will succeed or not. Knowing
both companies fairly well, I would be willing to bet my money on the
following scenario if Atmel gets bought:

1. AVR8 will stay in the market and future devices will be developed
mostly based on the XMEGA core, continuing strong revenues
2. ARM (although part of the original ASIC division) will stay with
its SAM7 / SAM9 / SAM3, this division is profitable and growing=20
3. Coming from the same site the CAP7 and CAP9 are ready to go, being
sold off, not profitable and needs lots of manpower
4. AVR32 although coming from the microcontroller division will be
deinvested, meaning no more additional money but trying to keep
already existing customers, if there is such a thing as an AVR32
customer. Has a long way to profitability
5. All PICxx, including PIC32 and dsPIC are probably all here to stay,
even though some devices are not profitable yet.=20

All in all, AVR8 is the big money maker, SAM7 and SAM9 make some money
and are growing fast, AVR32 is the money sink.

re the below...

On (1) and (5), if you agree that the newer atMega and XMEGA are
comparable +/- to at least some of the PICs, then the following
applies: If Microchip keeps semi-redundant microprocessors for more
than a year, it would be the first time I've seen a merger of two
companies with overlapping product offerings do so. The R.I.P. list
for such is lengthy if you think about it.

Scenario #1:

Microchip buys Atmel, junks the AVR and flicks two fingers to AVR customers
telling them to migrate to PIC. Unlikely, customers don't like to be
blackmailed.

Scenario #2:

Microchip buys Atmel, junks the ancient PIC line and flicks two fingers to
existing PIC customers telling them to migrate to AVR. Unlikely, customers
don't like being held at gunpoint.

Scenario #3:

They live happily ever after as comfortable bedfellows. Nightmare, but it's
probably what will happen if the two worlds merge.

So, if we line up the number of architectures that could end up on
Microchip's plate:

8051/251
MARC4
PIC32
AVR32
ARM7, ARM9, ARM11, Cortex-M3 + variants
AVR8
PIC10
PIC12
PIC16
PIC18
PIC24
PIC30/PIC33

Who, other than Motorola/Freescale, could contemplate such a disparate line
of microcontrollers? The AVR architecture can't die, it's too popular and
too-widely used, and Microchip can't shaft their investment in tools and
customers. Conclusion? Be prepared for both must stay.

However, I think it's a done deal. The cash offer, rather than stock, will
fly if Microchip can pull it off in these times.

One has to wonder how much existing base there are for PIC17 (nearly
gone and not even on your list?), PIC32 and AVR32....

Even PIC18 could be at risk?

What are you talking about? According the EETimes (so it MUST be true):

"The same story is repeated at Motorola and STMicroelectronics. Both at one
point had multiple MCU families and each now supports only one."

I didn't bring up ST as ST have rationalized their line of micros. ST now
have a robust portfolio even if you discount the ARM.

That is a dire article. It is riddled with problems and even mixes up Atmel
and Microchip at one point. Ok, Intel have dropped their own 804x, 80x51,
8080, 80x96, iAPX432, i860 (extra marks for anybody that remembers those
last two) and the XScale+Alpha they inherited from DEC/Compaq. Intel has
IA-32 and IA-64, but then the article forgets the black sheep money-sink,
the Satanic Itanic.

I guess that PowerPC and M.Core don't count. (Ok, M.Core never did...)

What a world. I'd hate to be responsible for the product lines of many of
these companies.

Microchip has always had a policy of never discontinuing manufacture of
a device, AFAIK. Even the ancient PIC16F84 is still made. Atmel has a
nasty habit of dropping chips from their portfolio and leaving
customers in the lurch. I would think that AVR users are safe, if
Microchip does take over Atmel.

Hi All

Has anyone successfully integrated the TLC5930 LED driver into an
LPC2138/48 (or any other ARM) project ? It seems an ideal IC to control
multiple RGB LED's including GLCD backlight, however it doesn't have a
true SPI interface so will have to be bit-banged or, so I'm lead to
believe, used on a dedicated SPI hardware channel.

Data sheet http://focus.ti.com/docs/prod/folders/print/tlc5940.html

The other thing I will probably have a problem with is the fact that the
BLANK signal has to be pulsed every 4096 GSCLK pulses.

Do people have experience of any other multiple (my design needs at
least 8) configurable RGB LED drivers... ?

Cheers
Toby

We have one design/product where LPC2138 handles 7 cascaded TLC5940 chips
which controls each 16 led's.

The SPI bus is used together with a PWM to handle the GSCLK and some IO's
manually handling the other control signals - works out fine.

The GSCLK is pulsed every 10 ms together with a restart of the pulse chain.

void LedRestartPWMandGS(void)

{

LED_BLANK_ON(); // Turn led off.

LED_XLAT_ON(); // Clock in GS data.

LED_XLAT_OFF();

LedInitUpdateGrayScale();

LED_BLANK_OFF(); // Turn led on and restart PWM counter.

}

Best regards

I think that is one of the major reason why Microchip is earning
money and Atmel is losing money. The other reason may be that
Microchip is more focused and Atmel has too broad product lines
(especially some lines which needs extensive investment yet
low yield like some of their ASIC business).

I agree. But it is not a good time for Microchip to take over Atmel
since the stock market has fallen so much that Atmel shareholders
may think Microchip is just bargain hunting and undervalue Atmel.
In the end, the bid may not be success after all.
