Thanks, I found it in the Technical Data
(datasheet?).
Thanks everybody for the prompt
response

Subject: AW: [motoroladsp] 5680x PINS -> electrical
specifications ? The DSP GPIO's are 5V tolerant. ADC is not. I can send you the
Technical Datasheet of the 805, or you can download it from
Motorola.

56F series have 5v tolerant I/O on most
pins. Download the data sheet (not the users manual) for the device
of interest, it will include electrical specs.

FYI, the DSP56F80x family is 5 volt
tolerant on the I/O pins.

Hi,
If you want to traslate voltage levels you can use a LVCC3245 part from
Texas Instruments. This chip translates from 3.3V to 5V and viceversa.
I hope this could be useful.

Does anybody know where can I get a good
electrical description of the Motorola DSP 5680x pins ?
I have to interface the DSP with components
that work with 5V. I guess that the DSP will never take 5V.
In the case of the logic ICs that I use (74HC
and 74ACT families), they have a clamping diode with 10mA max current. Therefore
I can supply them with 3.3V and put 5V in their inputs using current limiting
resistors.
Is this available in 5680x DSPs ? can this be
applied to all digital and analog pins ? If not, what do you do if you need
voltage level translation?
Thanks!
Mariano
