(2) CPU (IC6) SC3041K12F

1General

The CPU controls the loads of the main body and controls the system in synchronization with data transmission and reception through the optional controllers and serial data communication line.

2Features

The SC3041K12F is a high performance single-chip micro computer which is integrated with the necessary peripheral devices as well as the main core of 32-bit H8/300H CPU.

The 32-bit H8/300H CPU is of internal 32-bit composition, and is provided with simple and optimum commands designed for high speed operations with 16 bit x 16 general-purpose registers. It hand- les 16MB linear address space.

As the peripheral devices, included are the ROM, the RAM, the 16-bit integrated timer unit (ITU), the programmable timing pattern controller (TPC), the watch dog timer (WDT), the serial communication interface (SCI), the A/D convertor, the D/A convertor, the I/O port, the MDA controller (DMAC), and the refresh controller.
