Features of SH7125 and SH7124
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 a ROM, a RAM, timers, a serial communication interface (SCI), an A/D converter, an
interrupt controller (INTC), and I/O ports.
The version of the on-chip ROM is F-ZTAT
TM
(Flexible Zero Turn Around Time)* that includes
flash memory. 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.
