Preface
The H8/300L Series of single-chip microcomputers has the high-speed H8/300L CPU at its core,
with many necessary peripheral functions on-chip. The H8/300L CPU instruction set is
compatible with the H8/300 CPU.
The H8/3867 Series and H8/3827 Series have a system-on-a-chip architecture that includes such
peripheral functions as a as an LCD controller/driver, six timers, a 14-bit PWM, a two-channel
serial communication interface, and an A/D converter. This allows H8/3867 Series devices to be
used as embedded microcomputers in systems requiring LCD display.
The H8/3867 Series incorporates an LCD drive power supply and step-up constant power supply
(5 V), enabling a fixed 5 V voltage to be obtained independently of V
CC
.
This manual describes the hardware of the H8/3867 Series and H8/3827 Series. For details on the
H8/3864 Series instruction set, refer to the H8/300L Series Programming Manual.
