Lr3692

[Armando1989]

Hello there!
Just very simple question, may not simple aswer...
It would be feasible implementing sharp lr3692 lcd controller on max2 cpld as substitute?.
Im not sure since seems sharp chip have some microcontroller like block behavior inside.
Thanks!

Hello,

You may use any LCD as long as you have the controller IP(verilog or vhdl) to program inside MAX10.

Hi Farsbi!
Thanks in advance for your answer. I know i can usea any lcd as long as i have the controller. The question here is replacing the actual lr3692 sharp ic with cpld. If it is feasible for max ii family or not
Thanks

Hello,

You will need to refer to the Max II Handbook to ensure it is meeting the clock speed, Fmax and also the I/O standard available. It should be feasible Max II have similar electrical specifications needed with the LR3692.

Refer to below links for the relevant documentations for MAX II support:

Hello,

I wish to follow up on this thread. Do you have further questions or support needed?

Thank you.

Hi
Sadly the project is not feasible as involves other stuff as form factor and routing
Thanks anyway

Hi,

apparently LR3692 contains only digital functions of a LCD controller, analog display driver are external to it. In so far it should be possible to implement it in CPLD. Not sure if largest MAX II or MAX V with 2210 LE will be sufficient.

Also LR3692 is 5V device, there's no recent 5V capable CPLD with sufficient logic resources on the market.
