FAQ

What is the maximum operating frequency of the R5F213G6DNSP?

The R5F213G6DNSP supports a maximum operating frequency of 20 MHz when powered at 2.7–5.5 V using the XIN clock input. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 5 MHz to ensure stable operation. The on-chip high-speed oscillator also supports adjustable frequencies, though with less precision than crystal-based sources.

Does the R5F213G6DNSP support in-circuit debugging?

Yes, the R5F213G6DNSP includes on-chip debug functionality that enables real-time program execution control, register inspection, and breakpoint setting via a standard debug interface. This eliminates the need for external emulators and accelerates firmware development and validation cycles for the R5F213G6DNSP.

What are the low-power modes supported by the R5F213G6DNSP?

The R5F213G6DNSP supports wait mode (typ. 3.5 µA at 3.0 V with 32 kHz sub-clock) and stop mode (typ. 2.0 µA at 3.0 V), both retaining RAM content and allowing wake-up via interrupts or external events. These modes are controlled via system clock registers (CM0/CM1) and are integral to extending battery life in portable R5F213G6DNSP-based designs.

Can the R5F213G6DNSP's UART2 operate in I²C mode?

Yes, UART2 on the R5F213G6DNSP supports I²C-bus mode using pins P3_7 (SCL2) and P3_4 (SDA2). This allows direct communication with I²C-compatible sensors, EEPROMs, or other peripherals without additional level-shifting components - a confirmed capability documented in the R8C/3GD Group hardware manual.

What is the ADC resolution and channel count of the R5F213G6DNSP?

The R5F213G6DNSP features a 10-bit successive-approximation ADC with 8 input channels (AN0–AN11, with some shared with I/O pins). It includes sample-and-hold functionality and sweep mode for automatic sequential conversion - enabling accurate voltage monitoring and sensor interfacing in R5F213G6DNSP-based systems.
