H8S/20215R Group and H8S/20203R Group microcontrollers have improved usability and capabilities by enhancing the basic functions (timers, serial interface, and D/A converter) of 80-pin H8/300H Tiny products and adding new functions (event link controller and peripheral I/O mapping controller) plus a data transfer controller. They are also equipped with a built-in high-precision high-speed on-chip oscillator.
With 256 Kbytes of flash memory and 12 Kbytes of RAM built-in, real-time OS can be embedded.
An on-chip debugging emulator (E8a) is supported, providing a low-cost development environment.
