FAQ

What is the maximum operating frequency of the R5F213G1DNSP#U0 and under what voltage conditions?

The R5F213G1DNSP#U0 achieves a maximum operating frequency of 20 MHz when supplied with VCC ≥ 2.7 V. At lower voltages down to 1.8 V, the maximum supported frequency is reduced to 5 MHz per Renesas specification. This dual-voltage/frequency scaling allows flexible power-performance trade-offs in battery-operated designs where R5F213G1DNSP#U0 serves as the primary system controller.

Does the R5F213G1DNSP#U0 support I²C communication, and which pins are used?

Yes, the R5F213G1DNSP#U0 supports I²C communication via UART2 module operating in I²C mode. Pins P3_4 (SDA2) and P3_7 (SCL2) are dedicated to I²C data and clock functions, both configurable as open-drain outputs with internal pull-up resistors. These pins are shared with UART2 and clock synchronous serial I/O, requiring mode configuration in SFRs before use-critical for R5F213G1DNSP#U0-based sensor interface designs.

What is the function of the MODE pin on the R5F213G1DNSP#U0, and how must it be connected?

The MODE pin on the R5F213G1DNSP#U0 selects boot mode: it must be externally pulled high to VCC via a resistor (typically 10 kΩ) for normal program execution from internal Flash. Leaving MODE floating or pulling low places the device in special programming mode. This requirement is mandatory for reliable startup-failure to configure MODE correctly prevents R5F213G1DNSP#U0 from executing application code after reset.

How many analog input channels does the R5F213G1DNSP#U0 ADC support, and what is its resolution?

The R5F213G1DNSP#U0 integrates a 10-bit successive-approximation ADC with 8 configurable analog input channels (AN0–AN11, though only eight are active per variant). Channels AN0, AN1, AN5, AN6, AN8–AN11 are physically routed to pins 23, 24, 1, 2, 19–22 respectively. The ADC includes sample-and-hold and sweep mode-key for accurate R5F213G1DNSP#U0 implementations measuring thermistors or potentiometers in appliance control loops.

What low-power modes are available on the R5F213G1DNSP#U0, and what are their typical current draws?

The R5F213G1DNSP#U0 offers wait mode (3.5 µA @ 3.0 V with 32 kHz XCIN clock active) and stop mode (2.0 µA @ 3.0 V with all clocks halted). Both modes retain RAM content and allow wake-up via external interrupt or RTC alarm. These ultra-low quiescent currents make R5F213G1DNSP#U0 suitable for energy-sensitive applications like remote controls or battery-backed real-time clocks where minimizing standby drain is critical.
