Someone was asking if Atmel have integrated IEEE802.15.4 radio and micro.

Well, today ATmega128RFA1 was announced. Enjoy.

"Available now".

20x faster A/D (than your father's AVRs).

Onboard voltage regulators.

From technical point of view it's pretty good chip. I guess we'll have to see if it is really available.

We happen to be designing a line of wireless sensors right now. They will be AVR-based. If truly "available now" then it would be nice. But I'm not holding my breath.

On a side note, it appears that some "libraries" are available. I haven't registered or downloaded yet. But I happen to be a CodeVision user--certainly a manstream AVR compiler, that in fact claims the most registered users. Anyway, there are loud and vociferous claims that Atmel does not have favoritism when it comes to compiler brands.

OK, when code is made available for RF or QTouch or similar, is it available for CodeVision and ImageCraft? or only for other selected compiler brands? Alternatively, is the source available for porting?

Don't get me started. ;)

Probably a moot point as it will take as long to get into the supply chain as a '1284 or Xplain or Xmega or ... . (there is a part of "available now" that I always fail to understand.)

Pretty cool claim, when one of the major "competitors" is opensource where
you don't have to register. ;-)

Just curious, did Codevision finally go the C99 route? After all, the current
C standard celebrated its 10th anniversary now, and the ISO consortium is already
drafting a successor that is currently titled "C1x".

The Atmel 802.15.4 MAC software has always been available as source code, btw., but
as far as I can tell it might make use of a number of C99 features. Route under
MAC is also available as source code.

Excellent!
Been waiting for a 802.15.4 soloution for the stk600 for some time now :). This one-chip soloution seems good as well. The new 802.15.4 software library can't be downloaded yet though. the download link just sends you to a picture.

Hope the evaluation kits will be available soon!

Anyway, I doubt that all SW had been ported to that IC.

That's mega1281 (with minor changes to reduce power consumption) and at86rf231 on single die. at86rf231's registers are mapped into mega's memory, signals from pins are also mapped into single register.

Porting is pretty straightforward.

BitCloud and MAC have been ported and available.

with the demise of Meshnetics, what manufacturers can we go to if we seek an OEM module for 802.15.4 via Atmel, where the module is type certified by the regulatory authorities (FCC in the US) ? Competing with Digi XBee, Jennic, et al for apps that want to start with a certified module, not a chip? And a module with an optional PA/LNA for more than a couple of mW? (noting that France, Japan, etc. have low EIRP limits).

Atmel continues to manufacture ZigBit modules under its own brand.

Modules are in stock now, not sure if you can sell them without certification, so they must be certified.

PS: What this has to do with megaRF?

Ah thanks! I found ZigBit modules at DigiKey. I mistakenly thought these were dropped by Atmel - you don't read or hear about them in Atmel's announcements. The DigiKey catalog does show stock on hand if you search by part number, but searching by ZigBit doesn't index, nor are they indexed under Atmel/Wireless. Some items are still marked Meshnetics in their database.

But glad to see they exist.
Regarding the '15.4 MAC code for ZigBit modules - is it in synch with that for the dev kits we read about here? Is source for a ZigBit version of the MAC (and demo apps) availsble?

sorry if I confused - just thinking that the new chip would soon become a ZigBit module, or the equivalent from a module manufacturer. Yes?

I don't know about Atmel's MAC much. BitCloud uses its own version.

MegaRF pretty much eliminates the need for module.

You can only use a 2D flatpack version in that case, not the 3D version....

How so, if an OEM wants a drop-in module that comes with regulatory (FCC, et al) Type Certification for country x,y and z? Conversely, does not starting with a chip burden the Atmel customer with taking the design through type certification tests in each intended country for sales?

Don't you have to re-certify new product anyway regardless of module/radio type it uses?

AFAIK, there is no need in Europe to recertify a product if the module is already certified. There is only the need to certify that your equipment alone pass EN61000 or similar EMI compliance. For the rest, then you can rely on the manufacturer certification, and any drop in replacement doesn't need recertification.

BTW, 16KB of RAM is the double available in M1281, but the same than for M1284. A really nice feature in any case.

Hi rledyard,

Mounting it up side down and heating it will also solve your issue,

But now serious where to get the real silicon,

Usually, by the time a manufacturer announces an IC, it is within the
"general sampling" phase, i. e. not yet within full production. The idea
is that potential customers could then get enough samples of it to
design the new IC into their devices, so by the time production has been
ramped up fully, they could already start buying it in larger quantities.

So you'd have to ask the distributor which is responsible for your area
for samples.

That's the part of "available now" from the announcement (not "now sampling" or similar) that I always fail to understand from Atmel.

NB: I asked for samples right away via the Atmel Web site citing a current project. So far no contact from Atmel or the local rep.

I tried that once for an XMega chip I just wanted to evaluate. I got an email asking for details about my proposed project (which didn't exist, of course), expected usage and so on. I suppose I should have made some project up, with millions used each year, but I just gave up.

For the past few years, the Atmel Web site sample system hasn't worked too badly. Within a few days, I'd get contact from my local rep after the request filtered down--he'd have to screen for "legit" but as we use decent amounts of many AVR models that wasn't a problem.

Unfortunately they've now cut down the rep system (at least in my area) so I no longer have a "personal relationship" with a contact. So who knows.

"Phantom" parts are tough to get from any source. For real parts, though, Maxim, TI, and Analog Devices to mention a few have a fast and generally no/few questions asked sample policy. Curiously, the last few AD parts were shipped from the Philippines--you'd think there would be enough US demand to ship from somewhere in US. TI tends to ship out of DigiKey stock.

In the USA, not necessarily. For a certified module that contains both the radio and a fixed antenna, generally not. There also seems to be a module certification that allows you to use it with an antenna of less than X dBi gain without having to re-certify the end product -- I'm not totally sure how that works.

Not really. Have you ever looked at the "waffle packs" that might hold that AVR model? That quantity will be a small multiple of the number in each waffle pack.

788 is indeed strange. "factor 788" tells me it splits into 197 * 2 * 2,
so a tray would have to be 197 chips long and 4 rows wide. ;-)

thanks to Mr. Wunsch for the Dresden Elektronik hint!
I already sent a "power & UART base pcb" to a pcb manufacturer, so I'll be ready to go in a week or so.

but... I just worked with some smaller AVRs until now, AND with codevision only. so I guess I'll have a hard time getting to know and working with AVRstudio/WinAVR. :(

Hi guys,

I have several questions about the AVR2052: BitCloud Quick Start Guide:

1) Where can I adquire the STK600-ATmega128RFA1?

2) In the reference, it refer to a couple of guides that I couldn't find:

- AVR®2051: BitCloud Stack Documentation
- ATmega128RFA1 α-package Quick Start Guide

3) Why is this said in the guide (5.1 Overview)?

"For ZigBit /ZigBit Amp / ZigBit 900 platforms, end devices and routers and the
coordinator read the sensor data from on-board light and temperature sensors, and
forward collected data to WSN Monitor application for visualization. On
ATAVRRZRAVEN and megaRF platforms, zero values are sent to the network
coordinator to emulate sensor data and demonstrate data transmission."

Does not have the STK600-ATmega128RFA1 card (light and temperature)sensors? Why is sending zero values?

4)In the point 10.1.1, it is described tow different evaluation harward (1. For α-package and 2 For STK600 boards). What are the applications for each of them and the differences?

This is all by the moment. Thank you very much for your help.

Cheers, Ignacio

I have 3 of those Dresden Elektronik Boards now.
I made 2 PCBs for it, one containing the power supply (battery charger (MAX8606), LDO 3.3V) and a USB-UART (FT232RQ). The other pcb for analog input and digital IO (connector for I2C & SPI (=> ISP)), also equipped with a 3-axis accelerometer.

After having lots of trouble with these damn FT232RQ QFN-32 chips (I have soldered some QFN by hand, but these were the worst until now, by faaaaar), I can now talk to the ATmega128RFA1. Timers and ADC also working.
Just one little thing missing... - the wireless part!
:roll:

There's lots of reading and trying ahead of me, I don't have much experience with RF stuff, and there's not yet much out there for this chip. And Codevision does not yet support it.
So this will take some time.

I'll give you some more news as soon as I get some data over the air.

The Chip works fine on the Dresden Elektronik boards, piggybacked on a power & debug pcb I made (FT232, LiPo Manager, LDO, Reset Controller), and an additional analog IO board with an 3-axis accelerometer and 2 analog inputs.

I use Codevision, and as the RFA1 is not yet supported, I had to make a few things on my own:
- header file - see attachment
- compile in CV as ATmega1281
- flash'n'fuse with latest AVR Studio ( >=4.18 )
- change number of interrupt vectors in the CV project file *.prj to 72: "InterruptVectorsNumber=72". This can be done in any text editor.

Have fun! 8)
