The logo on the 626 3322 chip, what could that M stand for? Guesses?

Found out, it's Mitsumi. See here. Altough, meanwhile it's also stated on SparkFun, I could also have looked there earlier again. --Kosi2801 01:52, 20 December 2006 (EST)
The U7849 6Q63 chip is ROHM's ADPCM decoder LSI (BU7849?) and 6Q63 is Lot No., I guess. See here. --Demo-n 00:52, 5 January 2007 (EST)
- I guess you could really be right there! I was confused first, as the article you were linking to is talking about Rohm's BU8844FV chip, but later I read that the article says "The newest gaming console from Nintendo Co., Ltd., Wii, is slated to incorporate Rohm's ADPCM decoder LSIs.". They don't have a ?U7849 chip listed, but what's interesting is that Rohm has a BU7848, which actually is... a ADPCM decoder chip! On the other hand, their BU7848 is still in development according to their homepage and has a 24 pin package, whereas the U7849 in the Wiimote is a 16 pin package. [[1]] But there is another point that makes it quite plausible: That U7849 chip is located directly next to the BH7824 speaker amplifier chip - only on the other side of the PCB. On the other hand, the Rohm ADPCM chips support a sampling rate in the range of 4-32 khz, in 1khz steps - wheras it currently seems that you can setup the output sampling rate very precise, and 4khz currently(!) seems to be the maximum of what's possible.

[edit] Proposed merge
I think this article should be merged into Wiimote
- Isn't the Wiimote article way too long anyway? I think the Wiimote article should be split up into different articles, including information from here. OC 01:33, 5 January 2007 (EST)
