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.

The H8/3937 and H8/3937R Series are H8/300L Series microcomputers with an on-chip FLEX™ decoder. With on-chip peripheral functions including a FLEX™ decoder, five kinds of timers, a 2-channel serial communication interface, and an A/D converter, the configuration of these series makes them ideal for use as embedded microcomputers in pagers using the FLEX™ system, which require low power consumption. Models in the H8/3937 Series and H8/3937R Series are the H8/3935 and H8/3935R, with on-chip 40-kbyte ROM and 2-kbyte RAM, the H8/3936 and H8/3936R, with on-chip 48-kbyte ROM and 2-kbyte RAM, and the H8/3937 and H8/3937R, with on-chip 60-kbyte ROM and 2-kbyte RAM.

The H8/3937 and H8/3937R Series are also available in a ZTAT™* version with on-chip PROM which can be programmed as required by the user.

The H8/3937 Series supports non-roaming, while the H8/3937R Series supports roaming.
