The H8/3062 Group is a series of microcontrollers (MCUs) that integrate system supporting functions together with an H8/300H CPU core having an original Renesas 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, and other facilities. The 11 members of the H8/3062 Group are the H8/3062F-ZTAT R-mask version, H8/3062 (masked ROM version), H8/3061 (masked ROM version), H8/3060 (masked ROM version), H8/3064F-ZTAT B-mask version, H8/3062F-ZTAT B-mask version, H8/3064 masked ROM B mask version, H8/3062 masked ROM B-mask version, H8/3061 masked ROM B-mask version, and H8/3060 masked ROM B-mask version.
