FAQ
What is the maximum operating frequency and corresponding performance of the R5F100JKAFA#V0?
The R5F100JKAFA#V0 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, enabling deterministic real-time response for motor control and communication stacks.
Does the R5F100JKAFA#V0 support LIN bus communication, and which UART channels implement it?
Yes, the R5F100JKAFA#V0 supports LIN 2.1 and LIN 2.2A protocols via its UART0 and UART1 channels. Both channels include automatic LIN break detection, sync field handling, and checksum calculation - enabling direct connection to LIN transceivers without external protocol assist.
How much data flash does the R5F100JKAFA#V0 include, and what is its endurance rating?
The R5F100JKAFA#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing code execution from program memory while rewriting data flash - essential for over-the-air updates and event logging.
What are the low-power operating modes supported by the R5F100JKAFA#V0, and what functions remain active in STOP mode?
The R5F100JKAFA#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode, only the RTC, LVD, and selected interrupts remain active - drawing just 0.57 μA. This enables decade-long battery operation in metering and remote sensing applications where periodic wake-up is required.
Is the R5F100JKAFA#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100JKAFA#V0 is fully pin-compatible with all other 52-pin LQFP RL78/G13 variants (e.g., R5F100JCAFA#V0, R5F100JLAFA#V0), sharing identical pin configuration, electrical characteristics, and peripheral mapping - enabling scalable memory selection without PCB redesign.
