FAQ

What is the maximum operating frequency of the R5F213G4DDSP#U0 and under what voltage conditions?

The R5F213G4DDSP#U0 achieves a maximum operating frequency of 20 MHz when supplied with VCC ≥ 2.7 V. At lower supply voltages down to 1.8 V, the maximum supported frequency reduces to 5 MHz - a specification explicitly defined in Table 1.2 of the R8C/3GD Group datasheet (REJ03B0289-0100 Rev.1.00). This dual-voltage/frequency rating enables flexible power management in battery-operated designs.

Does the R5F213G4DDSP#U0 support I²C-bus communication, and how is it implemented?

Yes, the R5F213G4DDSP#U0 supports standard-mode I²C-bus communication via UART2 configured in I²C mode, using pins P3_7 (SCL2), P3_4 (SDA2), and P3_5 (CLK2). This is a full hardware implementation meeting I²C timing requirements without software bit-banging - confirmed in Table 1.1 (Serial Interface section) and Pin Function descriptions (Table 1.5). The R5F213G4DDSP#U0 can act as master or slave.

What are the A/D converter specifications of the R5F213G4DDSP#U0, and which pins are assigned to it?

The R5F213G4DDSP#U0 features a 10-bit successive-approximation A/D converter with 8 input channels (AN0–AN11), sample-and-hold circuitry, and sweep mode for automatic multi-channel scanning. Pins assigned include P0_6 (AN1), P0_7 (AN0), P1_0–P1_3 (AN8–AN11), and P0_1/P0_2 (AN6/AN5) - all listed in Table 1.4 and Table 1.5 of the official datasheet. Reference voltage is applied via P4_2 (VREF).

How does the R5F213G4DDSP#U0 handle reset and power-on initialization?

The R5F213G4DDSP#U0 incorporates a dedicated RESET pin (Pin 5) that triggers asynchronous hardware reset when driven low. It also includes an internal voltage detection circuit (VW0C/VW1C registers) providing power-on reset and selectable voltage monitoring thresholds. The MODE pin (Pin 4) must be externally pulled high to select single-chip operation mode - a requirement specified in Table 1.5 and Section 1.4 of the R8C/3GD documentation.

What packaging and compliance information applies to the R5F213G4DDSP#U0?

The R5F213G4DDSP#U0 is supplied in a 24-pin LSSOP package designated PLSP0024JB-A (formerly 24P2F-A), with 0.65 mm pin pitch. It complies with RoHS Directive requirements, as confirmed by Renesas' environmental statements in the document footer and Notice #10. The device is rated for "Standard" quality grade per Renesas' classification - suitable for office equipment, consumer appliances, and industrial robots, but not for safety-critical or life-support systems.
