Overview
The H8/3068F is a series of microcontrollers (MCUs) that integrate system supporting functions
together with an H8/300H CPU core having an original Renesas Technology architecture.
The H8/300H CPU has a 32-bit internal architecture with sixteen 16-bit general registers, and a
concise, optimized instruction set designed for speed. It can address a 16-Mbyte linear address
space. Its instruction set is upward-compatible at the object-code level with the H8/300 CPU,
enabling easy porting of software from the H8/300 Series.
The on-chip system supporting functions include ROM, RAM, a 16-bit timer, an 8-bit timer, a
programmable timing pattern controller (TPC), a watchdog timer (WDT), a serial communication
interface (SCI), an A/D converter, a D/A converter, I/O ports, a direct memory access controller
(DMAC), and other facilities.
The H8/3068F has 384 kbytes of ROM and 16 kbytes of RAM.
Seven MCU operating modes offer a choice of bus width and address space size. The modes
(modes 1 to 7) include two single-chip modes and five expanded modes.
The H8/3068F includes an F-ZTAT™* version with on-chip flash memory that can be programmed on-board. This version enables users to respond quickly and flexibly to changing
application specifications, growing production volumes, and other conditions.
Table 1.1 summarizes the features of the H8/3068F.
