Hope this helps.
if you are looking at something like the Belkin Mobile Numeric Keypd

which has a USB interface you will require a microcontroller with USB host facility such as the PIC24FJ64GB002
PIC24FJ64GB002
yeah, it is definitely possible..not only the keypad but the whole keyboard...
just go through the protocols for the at keyboard the older ones with the ps/2 connector...usb ones are the difficult cases...

You may also give a look to this if you feel comfortable with atmega..anyways you may give a look to the keyboard interfacing section over there.

the 16F877a or 18F4620 do not support USBYeah, that kind of keyboard.
Thanks for the MCU link. Is 877a or 4620 not capable of doing this kind of interfaces?
if you download the Microchip USB Framework for PIC18, PIC24 & PIC32
USB Application Design Center
you will find example code for attaching a USB keyboard to a Microchip Explorer 16 board
on my PC is it in directory
C:\Microchip Solutions v2011-10-18\USB\Host - HID - Keyboard
the example PIC24 code is for a PIC24FJ256GB110. However, it should be fairly easy to adapt it for a lower cost PIC24 such as the PIC24FJ64GB002
PIC24FJ64GB002
which can be used with Microchip's new microstick II
