NEC 78Kxx controllers

Far better instruction set, especially for a compiler. Fewer instructions to achieve anything useful. More easily available in Japan, and more readily accepted by Japanese clients. Many more bellylaughs reading the Manuals and more satisfaction from the voyage of discovery to determine what the status and control registers

*really* do. No more agonizing over which manufacturer to buy your parts or compilers from.

You forgot:

• Challenge and thrill of soldering down TQFP emulation sockets, and the skill-test of keeping the board functional long enough to debug your code.

• No more annoyance of having to stare at boxes of micros while you wait for other parts to arrive. The leadtimes are practically five months. (And the leadtimes on flash variants are practically the same as on masked variants).

Penny per feature, the ATmega series is much cheaper and considerably easier to work with, plus it has JTAG. In fact, the flash ATmega is cheaper than the equivalent mask-ROM 78K0.

Hi Mehta,

over the original 51 there is a speed advantage and there was once a price advantage, With 2 clock cores from Philips (LPC900 family) and Infineon (C800-family) or even some (sort of) single clock cores like Silicon Labs, the new generation 51s are faster, they are cheaper for the smaller flash devices due to strong competition and with the Keil development tools you get better tools than any 78k tool.
