R8C/1A Group, R8C/1B Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER REJ03B0144-0140 Rev.1.40 Dec 08, 2006 1. Overview These MCUs are fabricated using the high-performance silicon gate CMOS process, embedding the R8C/ Tiny Series CPU core, and is packaged in a 20-pin molded-plastic LSSOP, SDIP or a 28-pin plastic moldedHWQFN. It implements sophisticated instructions for a high level of instruction efficiency. With 1 Mbyte of address space, they are capable of executing instructions at high speed. Furthermore, the R8C/1B Group has on-chip data flash ROM (1 KB × 2 blocks). The difference between the R8C/1A Group and R8C/1B Group is only the presence or absence of data flash ROM. Their peripheral functions are the same. 1.1 Applications Electric household appliances, office equipment, housing equipment (sensors, security systems), portable equipment, general industrial equipment, audio equipment, etc. Rev.1.40 Dec 08, 2006 Page 1 of 45 REJ03B0144-0140 R8C/1A Group, R8C/1B Group 1. Overview 1.2 Performance Overview Table 1.1 outlines the Functions and Specifications for R8C/1A Group and Table 1.2 outlines the Functions and Specifications for R8C/1B Group.
