Instruction Set
The MN1030/MN103S Series of 32-bit microcontrollers has a simple instruction set designed to make C compiler output compact and highly optimized. It minimizes code size by adopting a variable length instruction format with a basic instruction length of only one byte. It is thus able to minimize increases in assembler program code size even though the only data transfers supported by the simple instruction set are load and store.

CPU Cores
AM30, AM31, and AM32 are 32-bit embedded application microcontroller cores from the Matsushita AM Series of C-oriented 8-, 16-, and 32-bit microcontrollers. Their specifications differ for certain instructions. The following are brief overviews of these three cores.
