Programming AT89LS53 in serial mode
Hello

The AT89LS53 from Atmel is a very interesting chip. It needs only 3V in operating mode, it`s in-system programmable and has 12k flash, enough for my needs.

I had a look in the datasheet and found out that the mcu is programmable in serial mode. It should be possible to develop software and a serial programming cable (with electronic parts) to write to the memory. Is programming in serial easier than in parallel mode?
Has anyone some suggestions for the circuit, there aren`t schematics avaliable on the i-net.
I have some C skills and worked a bit with at89c2051, but this type of mcu has not memory for my projects.

Greetings
