FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100JEAFA#10?
The R5F100JEAFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator. At this frequency, its typical active current is 66 μA per MHz - resulting in ~2.1 mA total at 32 MHz with all peripherals enabled. Power scales linearly with frequency, and STOP mode draws only 0.57 μA when RTC and LVD remain active.
Does the R5F100JEAFA#10 support LIN bus communication natively?
Yes, the R5F100JEAFA#10 includes UART peripherals with LIN bus support, providing hardware-level break detection, sync field generation, and checksum calculation per ISO 9141-2 and LIN 2.x specifications. No external transceiver is required for basic LIN slave functionality; a standard LIN transceiver (e.g., TJA1020) is needed for bus physical layer compliance.
How many analog input channels does the R5F100JEAFA#10 have, and what ADC resolution is supported?
The R5F100JEAFA#10 features a 10-bit successive approximation ADC with 12 selectable analog input channels (ANI0–ANI11). It supports internal 1.45 V reference voltage and an integrated temperature sensor - both accessible via dedicated ANI pins. Conversion time is programmable down to 1.5 μs per sample.
What debug interface does the R5F100JEAFA#10 use, and is SWD supported?
The R5F100JEAFA#10 uses Renesas' on-chip debug interface via the TOOLx pins (e.g., TOOLRxD/TOOLTxD on P11/P12), compatible with E2 emulator and E2 studio IDE. It does not support ARM-standard SWD; debugging relies on Renesas proprietary serial-wire debug protocol over dedicated pins, requiring Renesas debug probes.
Is the R5F100JEAFA#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCAFA#10 through R5F100JLAFA#10) share identical pinouts and electrical characteristics. Memory size, data flash presence, and temperature grade vary by suffix, but PCB layout and peripheral routing remain fully interchangeable across the R5F100JE-x family.
