SH7018 Features

The SH7018 is a CMOS single-chip microcomputer with a CPU based on Hitachi-original RISC-type SuperH™* architecture as its core. It also provides peripheral functions essential to system configuration.

The CPU incorporated into the chip supports the RISC (reduced instruction set computer) instruction set. Basic instructions execute in one cycle, so instruction execution times are extremely fast. The chip has an internal 32-bit architecture for efficient data processing. The CPU is capable of supporting applications employing real-time control. Such applications were not practical using previous microcomputers due to the extremely fast processing speeds required. It makes possible the development of systems providing high performance and excellent functionality at low cost.

The chip incorporates several peripheral functions essential to system configuration, such as ROM, RAM, timers, serial communication interface (SCI), A/D converter, interrupt controller (INTC), and I/O ports. It also supports external memory access, which allows for efficient connections to external memory and LSI devices. These features help to reduce system costs substantially.
