FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104FJAFP#V0?
The R5F104FJAFP#V0 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 yields ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA when running RTC and LVD-critical for battery-backed real-time logging in the R5F104FJAFP#V0.
Does the R5F104FJAFP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104FJAFP#V0 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to protect critical bootloader sections. It enables secure firmware updates using self-programming with boot swap-allowing validated new firmware to be written to inactive bank while running from active bank, then atomic switch on reset. This capability is fully implemented in the R5F104FJAFP#V0.
How many analog input channels and what ADC resolution does the R5F104FJAFP#V0 provide?
The R5F104FJAFP#V0 integrates a 10-bit successive approximation ADC with up to 20 configurable analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM pins for precision reference. It also features an internal 1.45 V reference voltage and integrated temperature sensor-enabling accurate environmental monitoring without external components in the R5F104FJAFP#V0.
What serial communication interfaces are available on the R5F104FJAFP#V0?
The R5F104FJAFP#V0 provides three UART/LIN channels (supporting LIN 2.2A physical layer), three to eight CSI channels (SPI-compatible), and four to ten I²C/simplified I²C channels-all configurable via peripheral I/O redirection registers. These interfaces operate independently and can be time-synchronized via the Event Link Controller, making them highly flexible for mixed-protocol industrial gateways based on the R5F104FJAFP#V0.
Is the R5F104FJAFP#V0 pin-compatible with other RL78/G14 variants in the same LQFP-44 package?
Yes, all RL78/G14 devices in the 44-pin LQFP-44 package-including R5F104FAAFP#V0, R5F104FCAFP#V0, R5F104FDAFP#V0, R5F104FEAFP#V0, R5F104FFAFP#V0, R5F104FGAFP#V0, R5F104FHAFP#V0, and R5F104FJAFP#V0-share identical pinouts, electrical characteristics, and peripheral mapping. Firmware and PCB layouts designed for one are directly reusable across this family, including the R5F104FJAFP#V0.
