For engineers reviewing the R5F104MHAFA#30 datasheet, R5F104MHAFA#30 pinout, R5F104MHAFA#30 application, or R5F104MHAFA#30 equivalent, key selection criteria include its 80-pin LQFP-0.65 mm footprint, -40°C to +85°C industrial temperature grade (D suffix), 192 KB code flash with data flash shield window, and support for background data flash rewriting (BGO) without CPU stall.
Technical Context
The R5F104MHAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a configurable Event Link Controller (ELC) enabling hardware-triggered peripheral chaining across 19–26 event sources.
Its power management includes HALT, STOP, and SNOOZE low-power modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable).
