CHAPTER 1: OVERVIEW
CHAPTER
1OVERVIEW
The S1C60R08 is a microcomputer with a CMOS 4-bit core CPU S1C6200C as main component, and a
built-in programmable RAM (ROM emulator). The S1C60R08 has almost the same functions as the
S1C60N08. The mask ROM in the S1C60N08 has been changed to a ROM emulator that allows the user to
rewrite programs using a Serial EEPROM.
1.1 Configuration
The S1C60R08 is a ROM emulator model of the S1C60N08 and the S1C60A08. Table 1.1.1 lists the differ-
ence between these target models.
