Section 1 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 H8/3847R Group, H8/3847S Group, H8/38347 Group, and

H8/38447 Group comprise single-chip microcomputers equipped with an LCD (liquid crystal

display) 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 H8/3847R Group, H8/3847S Group, H8/38347

Group, and H8/38447 Group ideally suited for embedded applications in systems requiring low

power consumption and LCD display. Also available are models incorporating 16 Kbytes to 60

Kbytes of ROM and 1 Kbyte to 2 Kbytes of RAM on-chip.

The H8/3847R is also available in a ZTAT™ *

version with on-chip PROM which can be

programmed as required by the user.

The H8/38347 and H8/38447 are available in a F-ZTAT™ *

version with on-chip flash memory

that can be programmed on-board.

Table 1.1 summarizes the features of the H8/3847R Group, H8/3847S Group, H8/38347 Group,

and H8/38447 Group.
