Need help fast

hi guys..
I am trying to interface b/w a microcontroller and 10 cascaded LED 5x7
panels and I have figured out most of the stuff. But I am trying to
find out something which has around 35 latches for the one LED panel
and some memory and clock too like a PLD which i can use for each LED
panel as midpart b/w the microcontroller and the LED block.
