Preface
The H8/300L Series of single-chip microcomputers has a high-speed H8/300L CPU core, with
many necessary peripheral system functions on-chip. The H8/300L CPU instruction set is
compatible with the H8/300 CPU.
On-chip peripheral functions of the H8/3637 Series include a high-precision DTMF generator for
tone dialing, a 14-bit PWM, five types of timers, two serial communication interface channels, and
an A/D converter.
This manual describes the hardware of the H8/3637 Series. For details on the H8/3637 Series
instruction set, refer to the H8/300L Series Programming Manual.

Section 1 Overview
1.1 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 H8/3637 Series of single-chip microcomputers features a high-
precision DTMF generator for tone dialing. Other on-chip peripheral functions include five types
of timers, two serial communication interface channels, an A/D converter, and a 14-bit pulse width
modulator (PWM). The H8/3637 Series includes three models, the H8/3637, H8/3636, and
H8/3635, with different amounts of on-chip memory: the H8/3637 has 60 kbytes of ROM and 2
kbytes of RAM; the H8/3636 has 48 kbytes of ROM and 2 kbytes of RAM; and the H8/3635 has
40 kbytes of ROM and 2 kbytes of RAM.
The H8/3637 has a ZTAT version with user-programmable on-chip PROM.
Table 1.1 summarizes the features of the H8/3637 Series.
