Thanks wicket!
actually when I clicked on your link, Konqueror told me its "<2>" (= second window on same URL). Alas hynix is not really easy to approach for what they offer, you seem to have to call them or mail them. The MCP NAND+RAM package quoted on your 2nd link is a 1GByte NAND plus 512MB RAM. We need 1GByte RAM and we don't care too much about NAND, though of course a 512+MB of NAND on same package would be more than welcome. Anyway we can do NAND on discrete chip, while RAM interface is only available on PoP balls of DM3730 in the CBP package we need to use. We are pondering to go for CUS package (no PoP at all) but that would cost us a UART and a McBSP :-/

PS: the micron 8Gbit density PoP RAM
datasheet
again only states 2Gbit density,

The 2Gb Mobile low-power DDR SDRAM is a high-speed CMOS, dynamic random-access memory containing 2,147,483,648 bits.

that's maybe why I failed on micron's components when searching for a chip 8 weeks ago.

BTW there's a tiny detail that makes our life as hw-engineers a whole lot harder than sw-engineers usually understand it was: when we decide for a component, then we need to know ONEHUNDRED PERCENT that it will fit and match and work. Then we have to spend a lot of money and time to *get* the component and integrate it into the design. And if we fail and picked the wrong component, we easily can burn 100s of k$. IOW we must act impeccable. Any OOOPS is a killer. While software engineers just deploy a patch to fix their oopsies ;-)

how about this? http://www.directindustry.com/prod/h...7-1274567.html
by the way is listed 1-*(to) 4 GB
buy hynix trought intermediars ?

Please don't get fooled, again 1..4Gbit aka 128 .. 512MByte. We know we can get 512MByte easily, even combined with 1GByte NAND. But we need 1GByte RAM!
See http://www.hynix.com/products/mobile...Map=MobileDDR2 linked directly from the page you referred to, resp http://www.hynix.com/products/mobile...sMap=MobileDDR which is the correct memory type for us (DDR[1])
It however seems hynix is not listing all they actually have.

[Alecsandru]

is listed as GB
GB-GigaByte
Gb - Gigabit
1 Byte=8 bit
or those standards are depreciated
sorry for the language but WTF
AND ABOUT NEO : emmc? how big? did you find chips?

eMMC chips are a nobrainer compared to this PoP disaster. We will pick a nice one when the time is up to do so. There's abundance to choose from and available options get better every week. 64GB is probably no issue and speed getting constantly better. Don't worry about eMMC, it will be "good enough"

Apparently a quick search of SK Hynix shows that they're developing DDR3 mobile RAM of 1GB up to 4GB and it is 20nm. Although, I couldn't find more info except for press release.

Hi
just a question about 3g compatibility since about 12 months ago Telstra in Australia changed there 3g network which left the Nokia n900 with no 3g access.
Will the Neo n900 have the same issue?

[joerg_rw]

sorry I can't answer that question since I neither know what Telstra Australia changed nor which bands and WWAN technology they offer now.
You'll need to find out which GSM and/or UMTS and/or LTE bands you could use, and then compare to the P*S8 WWAN module series at http://m2m.gemalto.com/products/m2m-advanced.html and check the bands those modules support - particularly we recommend the PLS8-E, PLS8-US, PXS8. When you found one of the modules that matches your needs, you order your Neo900 with the according module.

A bunch of gun thieves stole my phone!!!!
It sucks cos I can't find another to use, I have to buy another N900 as a standby as I wait for the neo900.
Track/security features were down, had truecrypt and SMSCon but....had not set it up....learnt my lesson...GO Neo900 go! We're watchin

It seems like Telstra switched its 3G band from 2100MHz to 850MHz in Semptember 2012 [1][2]. According to the modem data sheets the Neo900 should support the 850MHz band as long as you chose the PXS8 [3] or PLS8-US [4], NOT the PLS8-E.
