Wow! This group seems to have all but died. It used to be very vibrant.
I'm trying to determine how prevalent 4-bit MCUs are in the world. I know lots of products have used 4-bit devices in the past, coffee-makers, remote controls, microwave ovens, etc. I believe at one time, in terms of raw q uantity, they outnumbered every other sector. But I don't find very many a t mainstream manufacturers. I've also only found a couple companies with l ess visibility who supply these parts.
Anyone out there work with 4 bit MCUs? Anyone build products in the quanti ties of millions where a 4 bit MCU might make a difference price wise?
