Overview
The H8/300L Series is a series of single-chip microcomputers (MCU: microcomputer unit), built
around the high-speed H8/300L CPU and equipped with peripheral system functions on-chip.
Within the H8/300L Series, the H8/3887 and H8/3847 Series comprise single-chip
microcomputers equipped with a controller/driver. Other on-chip peripheral functions include six
types of timers, a 14-bit pulse width modulator (PWM), three serial communication interface
channels, and an A/D converter. Together, these functions make the H8/3887 and H8/3847 Series
ideally suited for embedded applications in systems requiring low power consumption and LCD
display. Models in the H8/3887 and H8/3847 Series are the H8/3882 and H8/3842, with on-chip
16-kbyte ROM and 1-kbyte RAM, the H8/3883 and H8/3843, with on-chip 24-kbyte ROM and 1-
kbyte RAM, the H8/3884 and H8/3844, with on-chip 32-kbyte ROM and 2-kbyte RAM, the
H8/3885 and H8/3845, with 40-kbyte ROM and 2-kbyte RAM, the H8/3886 and H8/3846, with
48-kbyte ROM and 2-kbyte RAM, and the H8/3887 and H8/3847, with 60-kbyte ROM and 2-
kbyte RAM.
The H8/3887 and H8/3847 Series are also available in a ZTAT™* version with on-chip PROM
which can be programmed as required by the user.
Table 1-1 summarizes the features of the H8/3887 and H8/3847 Series.
