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 H8/3834 Series has a system-on-a-chip architecture that includes such peripheral functions as
an LCD controller/driver, five types of timers, a 14-bit PWM, a three-channel serial
communication interface, and an A/D converter. This makes it ideal for use in systems requiring
an LCD display.
This manual describes the hardware of the H8/3834 Series. For details on the H8/3834 Series
instruction set, refer to the H8/300L Series Programming Manual.
Note: The terms H8/3834, H8/3834S, and H8/3834 Series used in the text refer to the products
shown below.
