From a historical viewpoint I think that’s unfair to the 65C816. It was launched in 1985; the eZ80 in 2001.
That’s a long time to learn from other people’s mistakes, if they even were mistakes for the time. I can’t find numbers for either on the web but I guess that, being pipelined, the eZ80 uses more transistors than the 65C816 (also, a Z80 already has about twice the number of transistors as a 6502).
If that’s the case, a better ‘improved 6502’ might have been too expensive for its market in 1985.
- PaulHoule 3y agoYou may be right. Zilog made numerous sequels to the Z80 in the 1980s that were somewhat going in that direction such as the Z180, Z280 and Z380 but none of them were as simple, clean and successful as the eZ80. Being a little late the eZ80 benefits from a lot of insight, it makes me think if the AVR-8 which is another architecture which ‘completes’ the 8 bit age.
