FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FEGFP#V0?
The R5F100FEGFP#V0 operates at up to 32 MHz, delivering 41 DMIPS performance. Its RL78 CPU core supports dynamic clock switching between selectable high-speed oscillator frequencies (1–32 MHz), with minimum instruction execution time adjustable from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), enabling precise trade-offs between speed and power.
Does the R5F100FEGFP#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F100FEGFP#V0 supports LIN bus communication through its UART peripheral, which is explicitly LIN-bus compatible per the RL78/G13 datasheet. It meets ISO 17987-4 timing requirements using programmable baud rate generators and dedicated LIN break detection logic, eliminating need for external transceivers in slave-node implementations.
How much data flash memory does the R5F100FEGFP#V0 include, and what is its endurance rating?
The R5F100FEGFP#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full 1.8–5.5 V VDD range. It supports background operation (BGO), allowing CPU code execution from program memory while data flash is being rewritten - critical for reliable firmware-over-the-air updates.
What low-power modes are available on the R5F100FEGFP#V0, and what is the lowest achievable current draw?
The R5F100FEGFP#V0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This enables decade-long battery operation in metering and sensor applications without compromising real-time event response.
Is the R5F100FEGFP#V0 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F100FEGFP#V0 is qualified for industrial applications with an operating ambient temperature range of -40°C to +105°C (G-grade). This rating is confirmed by the "G" suffix in the part number and applies across its full electrical specification, including flash programming, ADC accuracy, and oscillator stability.
