Overview
●The SH7144 Group and SH7145 Group single-chip RISC (Reduced Instruction Set Computer)
●microcomputers integrate a Renesas Technology original RISC CPU core with peripheral functions required for system configuration.
●The SH7144 Group and SH7145 Group CPU 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/high-functioning
●systems, even for applications that were previously impossible with microcomputers, such as realtime control, which demands high speeds.
●Features
●• Central processing unit with an internal 32-bit RISC (Reduced Instruction Set Computer)architecture
