DS80C400 is a Romless 8051 based microcontroller. i want to do programming of DS80C400 using keil C compiler. but how can i do its programming in C. how DS80C400 upon reset will fetch code from external ROM attached with DS80C400?
Kindly tell me. i have never interfaced external memory with any microcontroller.

HI

Since the DS80C400 dose not have JTAG interfae you will probebly need to use ICE in order to do some professional debug other wise you can also use a ROM EMULATOR (lower cost ) or move to more advnced ARM best microcontoller

Hi

Today 8 Bit ROMLESS or even flash ROM controller are legacy.

They have there pick some 10 years ago

Today even the ARM7 is geting old very fast

This is why I recommend the use of new generation controlleres like the CORTEX M3 or CORTEX M0

All the best
