Graphic controller for the ARM7 - ARM has no WAIT pin

Hello,

I hope anyone can help me, I understand German too.

My problem is: The graphic controllers form Epson, the S1D1 series have a WAIT signal to stop the bus when too busy. The ARM7 (LPC2214) does not offer a WAIT pin. It uses wait states instead. But when using DRAM with the Epson chips the delay is variable, between a few Nano sec and 1us. So performance is going down.

Can somebody advice a multi purpose TFT graphic controller for the ARM7 external bus?

Regards,
Christian
