1.1 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.
In terms of on-chip ROM, F-ZTAT^TM (Flexible Zero Turn Around Time)* version incorporating
flash memory and mask ROM version are available. The flash memory can be programmed with a
programmer that supports programming of this LSI, and can also be programmed and erased by
software. This enables LSI chip to be re-programmed at a user-site while mounted on a board.
The features of this LSI are listed in table 1.1.
