FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FHAFP#30?
The R5F100FHAFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction timing - from 0.03125 μs at full speed to 30.5 μs at 32.768 kHz - enabling dynamic power/performance scaling. This makes the R5F100FHAFP#30 suitable for both responsive real-time tasks and ultra-low-power periodic wake-ups.
Does the R5F100FHAFP#30 support LIN communication, and how is it implemented?
Yes, the R5F100FHAFP#30 supports LIN 2.2 communication through one of its two UART channels, which includes dedicated LIN-mode features such as automatic sync-break detection, checksum generation (classic or enhanced), and header timeout handling. This allows the R5F100FHAFP#30 to serve as a LIN slave node in automotive body electronics or industrial sub-networks without external transceivers beyond the physical layer.
How does the data flash functionality work in the R5F100FHAFP#30, and what is its endurance?
The R5F100FHAFP#30 integrates 8 KB of data flash memory with background operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash. It guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. The flash library reserves RAM starting at address FAF00H for self-programming operations - a detail confirmed in the R5F100xJ series documentation and required for safe firmware updates.
What are the low-power modes supported by the R5F100FHAFP#30, and what is the lowest achievable current draw?
The R5F100FHAFP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in metering and sensor applications - a key differentiator validated in Renesas' R01DS0131EJ0380 datasheet.
Can the R5F100FHAFP#30 interface directly with 1.8 V or 2.5 V peripherals, and how is this achieved?
Yes, the R5F100FHAFP#30 supports different-potential I/O interfacing: selected N-ch open-drain ports tolerate 1.8 V, 2.5 V, or 3.3 V logic levels without external level shifters. This is enabled by configuring pins with EVDD withstand voltage (for 64–128-pin variants) or VDD withstand voltage (for 20–52-pin variants like the R5F100FHAFP#30), verified in the "I/O port" section of the datasheet and applicable to its 44-pin LQFP package.
