1.1
This LSI is a single-chip RISC (Reduced Instruction Set Computer) microprocessor that integrates
a Renesas Technology original RISC CPU core with peripheral functions required for system
configuration.
The CPU incorporated in this LSI is the SH-2A CPU, which features upward compatibility on the
object code level with the SH-1, SH-2, and SH-2E microcomputers. The CPU has a RISC-type
instruction set and employs a superscalar architecture and the Harvard architecture, which greatly
improves instruction execution speed. In addition, the 32-bit internal-bus architecture independent
of the bus for the direct memory access controller (DMAC) enhances data processing power. This
CPU realizes low-cost, high-performance, and high-functioning systems for applications such as
high-speed realtime control, which has been next to impossible with the conventional
microcomputers.
This LSI has a floating-point unit and a cache.
In addition, this LSI includes on-chip peripheral functions necessary for system configuration,
such as, 32-Kbyte RAM for high-speed operation, a controller area network (RCAN-ET)*
IEBus
serial communication interface with FIFO (SCIF), I
timer pulse unit 2 (MTU2), an 8-bit timer (TMR), a realtime clock (RTC), an A/D converter, a
D/A converter, an interrupt controller (INTC), I/O ports, and advanced user debugger II (AUD-II).
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 reduce costs of
designing and manufacturing application systems.
The features of this LSI are listed in table 1.1.
