●Overview
●The H8/3048B Group is a series of microcontrollers (MCUs) that integrate system supporting
●functions together with an H8/300H CPU core having an original Renesas Technology architecture. In addition, the H8/3048F-ONE is equipped with an on-chip emulator (E10T)
●2.
●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 integrated timer unit
●(ITU), 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), a refresh controller, and other facilities.
●The H8/3048B Group has 128 kbytes of on-chip ROM and 4 kbytes of on-chip RAM. Seven MCU operating modes offer a choice of data bus width and address space size. The modes
●(modes 1 to 7) include one single-chip mode and six expanded modes. In addition to mask ROM products, the H8/3048B Group includes F-ZTAT™
● 1 version products with on-chip user-programmable flash memory. It enables users to respond quickly and flexibly to changing application specifications as well as to conditions when ramping up from initial to full
●volume production. The on-chip emulator (E10T)
●2 is capable of direct emulation of the
●microcontroller when mounted in the user’s system, thereby making possible on-board program
●debugging.
