2214 "simple" board design suggestions - skykotech - Feb 27 20:26:00 2004

I have about 4 or 5 projects that the LPC2214 would be about a
perfect fit. I have 3 sample 2214 parts, but hopefully can get a few
more down the road. I was wondering if some on this list might
appreciate a cheap, somewhat simple 2214 board, made available at
cost + shipping, and with the schematics and gerbers posted in the
files section. I have the time and desire, and I have routed many 2
and 4 layer boards including a very dense PCI card.

Anyway, if so, what would you want on the board? Just the processor,
regulators (simple linear?) for the 1.8V core and 3.3V IO, and a
crystal, with all other signals brought to .1 inch headers, or
something a bit more exotic, but maybe more usefull?

I am ok with making the board either 2 layers or 4 layers, but if it
is 4 layers, it really screams for doing *something* with the
external address/data bus. I want to try my hand at a compact flash
interface, but I could possibly attach that on a daughterboard at a
later date if that is viewed as an unwanted peripherial.

If you guys are interested, I will take note of your suggestions and
work up a schematic and layout for review.

Thanks!

Rick

I expect there will be plenty of eval boards around shortly. I
believe I have heard of some 3 or 4 companies that are designing them.
I don't know that they are all 2214s.

How did you get the samples? My local rep has told me to forget it
until Q4 or so. Did you get any insight into when the parts would be
in production? I am currently designing in an OKI 67Q5003, but would
like to consider this part if it is real. The package is also an
issue. The TQFP144 is way too large. So far Philips has not put any
of these chips into a QFN or BGA yet even though they are supposed to
have a QFN64 out shortly if I have my facts straight. I was told it
is delayed due to "mechanical" issues. Does that mean the chip is too
large for the package?

I can give you info on how the OKI ARM board is done, including info
on an Ethernet interface. Contact me by email.

I would suggest that you provide space on the board for the three
types of memory, SRAM, SDRAM and Flash. Then the Linux people can do
their thing with it.

I would love to see an EP1K50 mapped to the bus. That is what our DSP
board will have to provide various IO. I wouldn't mind using your
board as a prototype, but my guess is that ours will be ready to test
before yours. :(

small somewhat general purpose microcontroller board that is cheap
enough to leave in whatever prototype I make while I grab another one
off the shelf. I had in mind spending hopefully less than $50 or so
per stuffed board, if I made about 25 or so. > How did you get the samples? My local rep has told me to forget it

I got the parts from Phillips direct. It seemed pretty dang easy, I
just sent an email saying I was interested in the 2214 and asked if I
could have 2 to 5 samples. They sent three.

As far as the package size....the Oki part you mention is the same
size isn't it? I think i remember it being a 144 pin tqfp. If you
want a small bga part, perhaps an atmel AT91? > I can give you info on how the OKI ARM board is done, including info

with that part that I will not have time to get one of these projects
done by spring when it is due. I don't think you really want to
interface SDRAM to the phillips 2214...

I understand. But adding the footprints does not mean they need to be
populated. The board I have here is only about 4" on a side and
single sided with all the functionality I described including
Ethernet. Adding USB or some other IO would not take a lot more space
and the board can be made smaller by putting parts on the bottom. You
can see a picture at the
http://photos.groups.yahoo.com/group/OKI-ARM-mcus photo page. Then
the board can be much more widely used and populated according to the
needs. > > How did you get the samples? My local rep has told me to forget it

I'll give that a try. Did you send an email or call by phone? What
address or number?

The OKI part comes in a 144 pin BGA, 11 mm sq., 0.8 mm pitch. > > I can give you info on how the OKI ARM board is done, including info

Like I said above, you can put hardware on the board and not populate
the chips. Also, you don't need an OS really. I found out that there
is a microMonitor that provides debug support and hooks for using IO
like the serial port and Ethernet. It is from Lucent and it is open
source. I am no SW weenie, but it looks pretty easy to port. It is
running on this OKI board. > > I would love to see an EP1K50 mapped to the bus. That is what our

Don't you need some hardware for Robotics? Aren't you going to have
an FPGA or CPLD on board?

ethernet + compact flash

or lcd interface
either graphical or touch screen

or reasonable sized fpga
only hassle with fpga(xilinx or altera)
is needing a config prom

If you use one of the actel flash fpga's
could avoid this.

I remember seeing a link a while back
on the memec usa site of a board nicknamed gozilla
arm7 + actel flash fpga.

Could always do a similar board and try and aim it at the
education market ? Also maybe a bit of proto space or enough space for a few
opto couplers

You don't need a config prom. The CPU can configure the device either
through a serial pin or through an 8 bit parallel port. The EP1K50,
for example, is 96 kB which will fit in the Flash of any of these
devices. A little compression algorithm will likely squeeze that into
half that space. > If you use one of the actel flash fpga's
> could avoid this.

Yes, but they are not 5 volt tolerant. A lot of IO functions need to
deal with 5 volt IOs.

existing evaluation boards are mostly for the LPC2106, there is at
least one from Keil that uses the LPC2129. > How did you get the samples? My local rep has told me to forget it

oh come on, the LPC2129 which is in the QFN64 is already available on
evaluation boards from Keil, which seems to be in volume production
now because it can be ordered from the Philips web-site.
The LPC2129 is a superset of the LPC2124 (which is the 64-pin version
of the LPC2214).
The numbering scheme is a little confusion but heck, which vendor has
a logical numbering scheme ;-)

I don't know why Philips is telling me this stuff is not available.
If everyone else is gettng them, why am I being told differently? I
just got an email back from Philips this week saying the QFN packages
were delayed and not available with no date as to when they would be
out.

I guess I need to push harder.

I took a look at the Keil and Philips pages, and neither one shows a
QFN64 package for the LPC2129.

http://www.keil.com/mcb2100/specs.htm
http://www.keil.com/mcb2100/picture.htm
http://www.semiconductors.philips.com/pip/LPC2129FBD64.html#parametrics

Are you confusing the QFN with the LQFP package?

Sorry!!

I did confuse the LQFP package with the QFN package. I've seen the
LPC2106 in a QFN-48 but mo information about availability of the
64-pin device in QFN-64

Bob

btw. I did not even know that a QFN package is on the roadmap. Were
did you get the information about such a package for the LPC2xxx?

I didn't. Now that I have looked at it harder, I realize that I have
not seen any note on the larger part being available in a smaller
package. At least I can't say for sure I have seen anything. Philips
has done a pretty poor job of documenting where they are going with
these parts and I have found tons of discrepancies between the web
site, the data sheets and the info I have gotten directly from the
sales reps.

Even the latest User Manual for the LPC2114/2124/2212/2214 lists the
memory sizes differently on different pages.

The info I got from my sales rep shows, LPC2114FBD64, LPC2114FHN64,
LPC2124FBD64, LPC2124FHN64 part numbers. The same package designators
are shown for the LPC22 parts. I have also seen some web pages that
show a 64QFN part number. This info also shows LPC2194HBD64,
LPC2194HHN48, LPC2290HBD144 and LPC2294HBD144 part numbers which are
full automotive temps with CAN and ADC, the last two having an
external bus. The 2290 has no internal Flash.

But I think I can let this go now. Since the 2214 does not come in a
small package, I can't fit it on my board. I'll stick with the OKI
part in the 11mm BGA.
