Overview
The H8S/2339 Group is a series of microcomputers (MCUs: microcomputer units), built around
the H8S/2000 CPU, employing Renesas’ proprietary architecture, and equipped with peripheral
functions on-chip.
The H8S/2000 CPU has an internal 32-bit architecture, is provided with sixteen 16-bit general
registers and a concise, optimized instruction set designed for high-speed operation, and can
address a 16-Mbyte linear address space. The instruction set is upward-compatible with H8/300
and H8/300H CPU instructions at the object-code level, facilitating migration from the H8/300,
H8/300L, or H8/300H Series.
On-chip peripheral functions required for system configuration include DMA controller (DMAC)
and data transfer controller (DTC) bus masters, ROM, RAM, a 16-bit timer pulse unit (TPU),
programmable pulse generator (PPG), 8-bit timer, watchdog timer (WDT), serial communication
interface (SCI), A/D converter, D/A converter, and I/O ports.
A high-functionality bus controller is also provided, enabling fast and easy connection of DRAM
and other kinds of memory.
Single-power-supply flash memory (F-ZTAT™*) and mask ROM versions are available,
providing a quick and flexible response to conditions from ramp-up through full-scale volume
production, even for applications with frequently changing specifications. ROM is connected to
the CPU via a 16-bit data bus, enabling both byte and word data to be accessed in one state.
Instruction fetching is thus speeded up, and processing speed increased.
The features of the H8S/2339 Group are shown in table 1.1.
