FAQ

What is the maximum operating frequency and voltage range supported by the R5F2M112ANDD#U0?

The R5F2M112ANDD#U0 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation at 5 MHz down to 1.8 V. This dual-voltage/frequency capability allows flexible power management in battery-backed or wide-input AC/DC systems while maintaining full peripheral functionality across the entire 1.8–5.5 V range.

Does the R5F2M112ANDD#U0 include on-chip debug capability and flash security features?

Yes, the R5F2M112ANDD#U0 integrates on-chip debug circuitry enabling real-time breakpoint and register inspection without external emulators. It also supports flash security via ID code check and lock bit programming - preventing unauthorized readout or modification of firmware stored in its 8 KB program ROM and 2 KB data flash.

How many A/D converter channels does the R5F2M112ANDD#U0 support, and which pins are assigned?

The R5F2M112ANDD#U0 supports five 10-bit A/D converter channels: AN1 (P1_1), AN2 (P1_2), AN3 (P1_3), AN4 (P1_4), and AN7 (P1_7). AN0 is explicitly excluded per R8C/M11A Group specification, distinguishing it from the R8C/M12A Group which includes six channels with AN0 enabled.

What package type and pin count does the R5F2M112ANDD#U0 use, and is it RoHS-compliant?

The R5F2M112ANDD#U0 uses a 14-pin DIP package (PRDP0014AC-A) with 0.3-inch body width and standard 0.1-inch pin spacing. It is RoHS-compliant and lead-free, meeting JEDEC J-STD-609 Category 1 marking requirements for halogen-free materials and Pb-free terminations.

Can the R5F2M112ANDD#U0 generate PWM waveforms, and which timers support this function?

Yes, the R5F2M112ANDD#U0 generates PWM waveforms using Timer RB2 (programmable waveform generation mode) and Timer RC (PWM mode with 3 outputs or PWM2 mode with 1 output). These timers provide configurable duty cycle, period, and dead-time insertion - enabling precise motor speed control or LED brightness regulation directly from the MCU.
