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 H8/3834 Series features an on-chip liquid crystal display (LCD)
controller/driver. Other on-chip peripheral functions include five timers, a 14-bit pulse width
modulator (PWM), three serial communication interface channels, and an analog-to-digital (A/D)
converter. Together these functions make the H8/3834 Series ideally suited for embedded control
of systems requiring an LCD display. On-chip memory is 16 kbytes of ROM and 1 kbyte of RAM
in the H8/3832S, 24 kbytes of ROM and 1 kbyte of RAM in the H8/3833(S), 32 kbytes of ROM
and 1 kbyte of RAM in the H8/3834(S), 40 kbytes of ROM and 2 kbytes of RAM in the
H8/3835(S), 48 kbytes of ROM and 2 kbytes of RAM in the H8/3836(S), and 60 kbytes of ROM
and 2 kbytes of RAM in the H8/3837(S).
The H8/3834 and H8/3837 both include a ZTAT™ version*, featuring a user-programmable on-
chip PROM.
