FAQ

What is the maximum operating frequency and corresponding power consumption of the R5F104PJGFA#30?

The R5F104PJGFA#30 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to approximately 2.1 mA total supply current. Its ultra-low-power HALT mode draws just 0.60 μA when only the RTC and LVD remain active-critical for battery-backed applications where runtime must exceed years.

Does the R5F104PJGFA#30 support LIN bus communication natively?

Yes, the R5F104PJGFA#30 supports LIN 2.2 and SAE J2602 protocols natively through UART0 hardware, which includes dedicated break detection, sync field generation, and checksum calculation. No bit-banging or external LIN transceiver is required for basic node functionality-only a standard LIN physical layer transceiver (e.g., TJA1020) is needed for bus interface.

How many analog input channels does the R5F104PJGFA#30 ADC support, and what reference options are available?

The R5F104PJGFA#30 integrates a 10-bit successive-approximation ADC supporting up to 20 analog input channels. It offers selectable reference sources: external AVREFP/AVREFM pins, internal 1.45 V bandgap reference, or VDD. This flexibility allows precise ratiometric measurements with external sensors or fixed-voltage calibration against the internal reference.

What debug interface does the R5F104PJGFA#30 use, and how many pins are required?

The R5F104PJGFA#30 uses Renesas' on-chip debug interface with single-wire SWD (Serial Wire Debug) capability, requiring only two pins: P40 (debug clock/data) and RESET. No JTAG header or additional debug signals are needed, simplifying PCB layout and reducing debug footprint-especially valuable in space-constrained industrial modules.

Is the R5F104PJGFA#30 pin-compatible with other RL78/G14 variants in the same package?

Yes, all RL78/G14 devices in the 100-pin LFQFP-0.5mm package-including R5F104PJGFA#30, R5F104PLGFA#30, and R5F104PKGFA#30-share identical pinouts and electrical characteristics. Memory size and peripheral enablement differ by part number, but PCB layout, decoupling, and signal routing remain fully interchangeable across the family.
