FPGA to 6502
Posted: Tue Jun 22, 2021 1:10 am
Hi guys,
Being somewhat disinterested in an old school solution for video for my 6502 project and after playing with the SPLD's I have an interest in playing with FPGA's. I found the Xosera project based on the ICE40 which, as I understand it, is the same FPGA being used in the Vera on the Commander X16. I think I've settled in on this chip for my first foray.
The ICE 40's are a 3.3v logic level so it appears I need to do some work with level converting, not a huge deal but I'm looking for an 8 bit cmos level shifting transceiver for the data lines.
I found the 74ALVC164245, which seems to check all the boxes, but is 16 bit, I only need 8 bits and can't seem to locate an 8 bit version. Below are the specs of what I think I need, if anyone can help I'd appreciate
DIP *highly desired, but not necessarily required.
Bi-Directional 5v to 3.3v translation
CMOS to CMOS
8 bit
