Where can I find the pinouts for micro controllers? Specifically BK3254.
Where can I find the pinouts for micro controllers? Specifically BK3254.
I cannot find it on the suppliers website, which I really dislike. I would e-mail info@bekencorp.com and ask for it.
Hi jcbrinsfield,
have a look at this. hope it's what you were looking for:

Looks like datasheet and related info (including firmware) is behind FTP server. But it's locked and you need password to get in there, AFAIK.
It seems like it's a pinout for a module that uses this chip, not particular chip in question.
p.s. Polaroid PBT641 Bluetooth Speaker uses the said chip, but in SMD DIP package.
The chip has the code "BK3254SS280" Which I think stands for "BK3254, Single Sided version, 28 pin"
Pin 1, 2, 3, 4, 6, 7, 8, 10, 11, 13, 14, 15, 16, 25, 26, 27 looks like they're NC on this circuit.
Pin 5 is connected to BT antenna.
Pin 9 is connected to GND.
I've got the datasheet from the manufacturer, but they say since this is confidential, I am disallowed from sharing it on public sites (thus have to use email)
If you want it, please let me know through this throw-away mail address: netvolution2014@gmail.com
Proof:
Note: You'll receive the datasheet free of charge. I'm just required to keep this datasheet otherwise confidential as requested by the provider.
Found the data sheet freely available with Google (online), but schematics are not included.
