If not, you can use the divider for inputs and either hope the ROM will accept your 3.3V logic outputs or else use a simple transistor stage (MOSFET or BJT and a couple of resistors) for the outputs to the ROM. Using a transistor will invert the signal but you can correct in software. | |

They require need Vcc = 5V but will (likely) see 3.3v as high input level for the address. I assume the ROM will output data as 5v high level. | |
