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 H8/3644 Group of microcomputers are equipped with a UART
(Universal Asynchronous Receiver/Transmitter). Other on-chip peripheral functions include five
timers, a 14-bit pulse width modulator (PWM), two serial communication interface channels, and
an A/D converter, providing an ideal configuration as a microcomputer for embedding in high-
level control systems. In addition to the mask ROM version, the H8/3644 is also available in a
ZTAT™ *
version with on-chip user-programmable PROM, and an F-ZTAT™ *

version with on-
chip flash memory that can be programmed on-board. Table 1 summarizes the features of the
H8/3644 Group.
