Can anybody plz suggest me a good controller which has USB communication facility and where I can interface PS/2 keyboard, and GLCD. 8051 versions will bw prefered.
I want to have a controller with USB facility so that it can be connected with pen drive and PS/2 keyboard will be interfaced separately. 20*4 LCD display could do in place of GLCD.
My thinking, if you want to use GLCD 128x64 and bigger displays then its nice to have more space for program and RAM. From Microchip family of products all weaker and below PIC18F is out of consideration.
Check these:
PIC18F45K22, PIC18F46K22, PIC18F4685,...
I currently making some project with Touch GLCD and I plan to switch from PIC18F45K22 to PIC18F4685. Additional space for data and RAM is always needed in GLCD and TFT projects, my project expand with screens and elements that I need, for now data increase more then 32KB (PIC18F45K22).
8051 can do the job if you use LCD, but all depends from project needs.
Irrespective of the choice of the controller, I only wanted to point out a good product selection tool on the Microchip website. It has helped me select the right MCU in the past. The MCU specs (8051 / PIC / others), as tpetar has already mentioned, will depend on the project requirements.
