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 H8/38024 Group, H8/38024S Group, and H8/38124 Group comprise single-chip microcomputers equipped with a LCD (Liquid Crystal Display) controller/driver. Other on-chip peripheral functions include six timers, a two-channel 10-bit pulse width modulator (PWM), a serial communication interface, and an A/D converter. Together, these functions make the H8/38024 Group, H8/38024S Group, and H8/38124 Group ideally suited for embedded applications in systems requiring low power consumption and LCD display. Models in the H8/38024 Group, H8/38024S Group, and H8/38124 Group are the H8/38024, H8/38024S, and H8/38124 with on-chip 32-Kbyte ROM and 1-Kbyte RAM, the H8/38023, H8/38023S, and H8/38123 with on-chip 24-Kbyte ROM and 1-Kbyte RAM, the H8/38022, H8/38022S, and H8/38122 with on-chip 16-Kbyte ROM and 1-Kbyte RAM, the H8/38021, H8/38021S, and H8/38121 with 12-Kbyte ROM and 512 byte RAM, and the H8/38020, H8/38020S, and H8/38120 with 8-Kbyte ROM and 512 byte RAM.

The H8/38024 is also available in a ZTAT™*1 version with on-chip PROM which can be programmed as required by the user. The H8/38024 is also available in F-ZTAT™*2 versions with on-chip flash memory which can be reprogrammed on board.

The H8/38124 is also available in an F-ZTAT™ version with on-chip flash memory that can be programmed on board.
