USB to PS/2 IC for BOTH Keyboard and Mouse interface

[shmueld]

We are looking to design a PS/2 to USB converter for both a Keyboard and Mouse interface. We have experience with the USB via FTDI chips but no experience with the PS/2 interface. We are looking for a single chip solution that will be able to handle both the mouse and keyboard interface. What are the options available ? We really need a chip that will handle the USB side of things seamlessly - else wise we will need to to a FTDI solution and possibly an additional chip.

Hi,

mouse and keyboard are: USB or PS/2?

what´s the other side? A PC? which OS?

but no experience with the PS/2 interface.

There is no way around: You need to read and understand the specification.... unless you find a ready to buy solution for your problem.

PS/2 is a simple serial interface. It should be possible to convert USB devices from one to the other with minimal protocol conversion between them at serial level.

Klaus,

The mouse and keyboard are PS/2 and the USB output is into a PC with OS Windows or Linux.

Do you or anyone else know of specific chips which can do all the required USB communication so that all we are left with is the keyboard \ Mouse PS/2 interface ?

Hi,

Out of curiosity I did an internet search. And guess hwt? There are many "USB PS/2 adapters".
To buy for little money.

I really ask myself why you didn´t do the same...

Klaus,

Yes we know all about these but we need an adapter that will work minimally from -10 deg C to +60 deg C and ideally -40 deg C to +85 deg C ! As far as we know there are no such adapters available !?
