Description
The H8/3069R 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 H8/3069R has 512 kbytes of flash memory and 16 kbytes of RAM. Six MCU operating modes offer a choice of bus width and address space size. The modes (modes 1 to 5, 7) include one single-chip mode and five expanded modes. The H8/3069R 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.
