PIC18F45K22, Pbp and 16*16 rgb led matrix, will speed be enough?

Hello, will be mentioned combo enough to read from serial eeprom and display on led panel some graphical data at high speed, say 50fps?

Why do you need 50fps ? NTSC TV is 30, Pal is 25, normal cinema is 24, or home movies 18fps or less are quite OK.

I guess it depends on the interface of the LED-matrix. Is it a serial, SPI type interface with the actual LED-drivers and multiplexer built in or do you intend to drive the actual LEDs with the PIC?
Let's say 8bits per color * 3colors * 256 pixels * 50 frames = 307200 bits per second or 38400 bytes per second.
But why 50 frames per second, I'm quite sure 25 would suffice which would reduce the needed bandwidth to 50% or ~155kbit per second. Then of course the actual bandwidth is twice that since you need to first read the data from external memory then send it out again.

Do you have a link to the display in question.

I don't have led panel, I bought for cheap pack of 1000 of RGB 5mm leds. 50fps is for extra smoothness. Commercial scrolling marque led displays run at 60 fps.

anything more than 30 is overkill, and you wont notice a differance.
