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 H8/3857 Series has the following on-chip peripheral functions required for system
configuration: a maximum 1,280-dot display LCD controller, four types of timers, a 14-bit PWM,
a 2-channel serial communication interface, and an 8-channel A/D converter.
The H8/3854 Series has the following on-chip peripheral functions required for system
configuration: a maximum 640-dot display LCD controller, three types of timers, a single-channel
serial communication interface, and a 4-channel A/D converter.
Both series can be used as embedded microcomputers in systems requiring LCD display.
The H8/3857, H8/3856, H8/3855, H8/3854, H8/3853, and H8/3852 are available in mask ROM
versions, and the H8/3857 and H8/3854 are also available in an F-ZTAT™* version which allows
programs to be written after the chip is mounted on a board.
Note: * F-ZTAT (Flexible Zero Turn-Around Time) is a trademark of Hitachi, Ltd.
This manual describes the hardware of the H8/3857 Series and H8/3854 Series. For details on the
H8/3857 Series and H8/3854 Series instruction set, refer to the H8/300L Series Programming
Manual.

Note:
*
Note that the H8/3854F (F-ZTAT version) and H8/3854 (mask ROM version) have different
ROM and RAM sizes.
When carrying out program development using the H8/3854F with the intention of mask
ROM implementation, care must be taken with ROM and RAM sizes since the maximum
sizes for the mask ROM version are 32 kbytes of ROM and 1 kbyte of RAM.
