FAQ
What is the maximum operating frequency and performance rating of the R5F100LFAFA#30?
The R5F100LFAFA#30 operates at up to 32 MHz with a performance rating of 41 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. Its minimum instruction execution time is 0.03125 μs under 32 MHz operation, enabling deterministic real-time response in motor control and sensor fusion applications. The R5F100LFAFA#30 maintains this performance across its full 1.6–5.5 V supply range.
Does the R5F100LFAFA#30 include an integrated real-time clock (RTC) with calendar functionality?
Yes, the R5F100LFAFA#30 includes a dedicated real-time clock peripheral supporting full calendar operation (year/month/day/hour/minute/second), alarm generation, and clock correction. It operates independently in STOP mode with only 0.57 μA current draw when powered by VDD, making it suitable for time-stamped logging and scheduled wake-up in battery-powered systems. The R5F100LFAFA#30 RTC does not require external crystals for basic operation, though a 32.768 kHz crystal can be used for enhanced accuracy.
How much flash and RAM memory does the R5F100LFAFA#30 provide, and what are their usage models?
The R5F100LFAFA#30 provides 128 KB of code flash memory, 8 KB of data flash memory, and 12 KB of on-chip RAM. Code flash stores executable firmware and constants; data flash supports EEPROM-like non-volatile storage with 1,000,000 write cycles and background operation-ideal for calibration data and event logs. RAM is used for stack, heap, and runtime variables. The R5F100LFAFA#30 flash library reserves specific RAM regions (e.g., F7F00H for xL variants) for self-programming operations.
What serial communication interfaces are available on the R5F100LFAFA#30, and do they support LIN bus?
The R5F100LFAFA#30 integrates two UART channels with built-in LIN bus support (LIN 2.2 compliant), three I²C channels (including simplified I²C), and up to eight CSI (SPI-compatible) channels. UART0 and UART1 each support automatic LIN header detection, checksum generation, and slave-mode response handling-enabling direct integration into automotive body electronics and industrial sub-networks without external LIN transceivers. The R5F100LFAFA#30 pin mapping allows UART/LIN functions on multiple pin groups for flexible board routing.
What low-power modes does the R5F100LFAFA#30 support, and what is its lowest active current consumption?
The R5F100LFAFA#30 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-enabling decade-long battery operation in intermittent-sensing applications. Active-mode current is 66 μA per MHz at 32 MHz (2.112 mA typical), scalable via clock gating and peripheral disable. The R5F100LFAFA#30 achieves this via segmented power domains, dynamic voltage scaling, and ultra-low-leakage process technology-verified across –40°C to +85°C ambient temperature.
