There's the beauty of the 8051 - you've just mentioned 4 different manufacturers in one breath! Yes, this was the single reason I chose 8051 in the first place, I'm all to aware of chip manufactures pulling the carpet from under ones feet. In fact Atmel did this to me by dropping it's PDIL 40 AT89C51ED2 part, I have about 100 in stock, good chip but when it comes to mips AVR wins through. Andy Neil said:
AVRs are single-source - which may or may not be an issue to you. Thats true, but with their new line of xmega series(check price and compare), they seem stable, also the AVR community is massive. Andy Neil said:
Out of interest, did you consider ARM Cortex-M3 or -M0 in your search for your 8051-replacement? I would like to move up to Arm7 but the tool chain is short and very expensive by contrast AVR's tool chain which is very long and at low cost, in fact my AVR compiler I've just ordered supports double 64bit floating point.It has cost me as little as £100 or so to migrate. I'm happy with 20mips at the moment, I'm sure someone will produce prototyping boards for the Xmega series if they havent already. JA |
