Features of SH7083, SH7084, SH7085, and SH7086

This LSI is a single-chip RISC (Reduced Instruction Set Computer) microcomputer that integrates a Renesas Technology original RISC CPU core with peripheral functions required for system configuration.

The CPU in this LSI has a RISC-type instruction set. Most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. In addition, the 32-bit internal-bus architecture enhances data processing power. With this CPU, it has become possible to assemble low-cost, high-performance, and high-functioning systems, even for applications that were previously impossible with microcomputers, such as real-time control, which demands high speeds.

In addition, this LSI includes on-chip peripheral functions necessary for system configuration, such as large-capacity ROM and RAM, a direct memory access controller (DMAC), a data transfer controller (DTC), timers, a serial communication interface (SCI), a serial communication interface with FIFO (SCIF), a synchronous serial communication unit (SSU), an A/D converter, an interrupt controller (INTC), I/O ports, and an I2C bus interface 2 (I2C2).

This LSI also provides an external memory access support function to enable direct connection to various memory devices or peripheral LSIs.

These on-chip functions significantly reduces costs of designing and manufacturing application systems.
