国外友人求助，关于PMB6850 and PMB6250集成电路

那位朋友知道小8的集成电路，这是原文：

其实，6688的芯片是支持GPRS class 12的！请查看 Infineon芯片PMB6850/E-GOLD V1和SMARTi PMB6250
Ok for the first time I have opened my phone, and can confirm to everyone who doesn't believe that the SL45 is GPRS compatible that they are wrong! It is GPRS class 12 compatible, Siemens never enabled it because if SL45 had GPRS then there would be no point in S45, and they wanted more profit. These are the Infineon chips inside:

SMARTi PMB6250

Here are pics to prove it, I couldn't really get better ones than this, u can just about read what it says on the chip.


This shows us all the parts of the SL45 when it is taken apart:

This shows the main E-Gold chip. On the chip it has the Infineon logo and says 'PMB 6850 E'

This shows the dual band GSM chip, it has the Infineon logo and says on the chip '6250 SMARTI'

Also it is nothing to do with the processor because these 2 chips work together, and the processor is located on the E Gold chip - so the processor has to be fast enough. Infineon wouldn't make an onboard processor if it wasn't fast enough for all the other functions that the chip supports!

硬件要软件支持.
6688没有编写相关的软件,所以,6688不能用GPRS.

Xinshou

对于国外高手，软件不是个问题。以前大家都说硬件不支持。
我的看法是，虽然芯片支持，但是就怕小8主板上的线路设计不支持，从而可说硬件不支持GPRS。

能不能找到更详细的资料，他可是个高手啊，呵呵。

虽然不能榜上什么忙，但顶上去，也是支持！

hmj

能否从3618（S45）的FUBU下手，找到GPRS的突破口？

wwssff

他们确实认为硬件上是支持GPRS的.

pioneercpu

硬件上是支持GPRS？？？？？？？？？？？？？？

硬件上是支持GPRS！！！！！！！！！！！！！！1

高什么手，多半是末天看到了芯片的说明书，看到上面有支持gprs的片言只语而已。能不能实现，还要看很多东西的。

wwssff

很多东西就是在怀疑声中实现的，要我是设计师，芯片有的功能我一定会在电路上考虑，留下接口，时机成熟就变一下系统就出来了。

期待实现gprs,用数据线连接笔记本,cnwap 20元包月无线上网:)
早日实现!!

wwssff

20元包月啊，那么便宜。

我这里包月30呢

下午四点半

我10块不限量。^_^

期待梦想…………

我们这里也是20包月，但只对动感地带的卡。

芯片支持还要设计到很多方面的配合，希望6688的设计已经是配合好的，只是在软件和最终的接入上做了屏蔽。我始终觉得工程模式里的“no GPRS support”有点诡异。
