Here is the link to a small product brief of sm342....
Could you please check it out???....They havent specifically told the name of the processor, they have just mentioned that it is a 32 bit risc processor..
Does the selection of the programmer and comiler for an soc depends solely on the core only???...coz in that case there is another Multimedia SoC sm341 which uses 8051, so for that can any of the 8051 programmers like USB Universal In-Circuit Programmer, model:PRESTO can be used with keil micro vision as compiler... ???
