I am currently learning to program a NXP LPC1347 for a project which will utilize two SSD1963 controller-based displays. The issue is that the uC only has 51 IO pins whereas the total pins of the display would amount to 26. This leaves too few pins for the peripherals that I need to have on the board (switches, UART, SPI, I2C)
I was initially going to upgrade to a LPC17xx but I figured I could also multiplex the 8-bit data and could save quite a few pins. Perhaps I could even multiplex the 5 control signals as well. Is this a better solution than using a more complex and more expensive part like a LPC17xx or are there pitfalls that I'm not considering?
