The R5F100FJAFP#30 supports a maximum CPU clock frequency of 32 MHz using its on-chip high-speed oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and -40°C to +85°C ambient conditions. This enables 41 DMIPS performance while sustaining ultra-low active current (66 μA/MHz).
Does the R5F100FJAFP#30 include a hardware real-time clock (RTC)?
Yes, the R5F100FJAFP#30 integrates a full-featured RTC with calendar support (99-year range), alarm function, and clock correction capability. It operates independently in STOP mode with only 0.57 μA consumption, driven by an external 32.768 kHz crystal connected to RTC_X1/RTC_X2 pins.
Can the R5F100FJAFP#30 perform data flash writes while executing code from main flash?
Yes, the R5F100FJAFP#30 supports Background Operation (BGO) for its 8 KB data flash. This allows the CPU to execute instructions from code flash memory concurrently with data flash erase/write operations - eliminating firmware stalls during field updates or parameter logging.
What communication interfaces are available on the R5F100FJAFP#30?
The R5F100FJAFP#30 provides up to 2 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. UART0 includes native LIN 2.2 support with automatic sync-break detection and checksum generation, making it suitable for automotive body electronics and industrial networks.
Is the R5F100FJAFP#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100FJAFP#30 shares identical 44-pin LQFP pinout and electrical characteristics with all RL78/G13 members in the PLQP0044GC-A package (e.g., R5F100FAAFP#30, R5F100FKAFP#30), enabling drop-in replacement across flash/RAM configurations without PCB changes.
