The H8S/2378 Group and H8S/2378R Group microcomputers (MCU) made up of theH8S/2000 CPU employing Renesas Technology´s original architecture as their cores, and the peripheral functions required to configure a system. TheH8S/2000 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a simple and optimized instruction set for high-speed operation.The H8S/2000 CPU can handle a 16-Mbyte linear address space. This LSI is equipped with direct memory access controller (DMAC and EXDMAC) and data transfer controller (DTC) bus masters, ROM and RAM memory, a 16-bit timer pulse unit (TPU), a programmable pulse generator (PPG), an 8-bit timer (TMR), a watchdog timer (WDT), a serial communication interface (SCI and IrDA), a 10-bit A/D converter, an 8-bit D/A converter, and I/O ports as on-chip peripheral modules required for system configuration. I2C bus interface 2(IIC2)can also be included as an optional interface. A high functionality bus controller is also provided, enabling fast and easy connection of DRAM and other kinds of memory. A single-power flash memory (FLASH) version is available for this LSI´s ROM. The FLASH version provides flexibility as it can be reprogrammed in no time to cope with all situations from the early stages of mass production to full-scale mass production. This is particularly applicable to application devices with specifications that will most probably change.
