FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100GFANA#20?
The R5F100GFANA#20 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions using the EEMBC CoreMark benchmark. The high-accuracy ±1.0% on-chip oscillator ensures timing stability across voltage and temperature without requiring external crystals.
Does the R5F100GFANA#20 support hardware LIN bus communication?
Yes, the R5F100GFANA#20 supports LIN 2.2-compliant communication via its UART0 peripheral, which includes dedicated hardware features for LIN: automatic break detection, sync field handling, checksum generation/validation, and timeout recovery. This eliminates software overhead and ensures robust communication in automotive subnetworks.
What are the low-power modes available on the R5F100GFANA#20, and what is the lowest achievable current draw?
The R5F100GFANA#20 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at 25°C. This ultra-low quiescent current enables decade-long battery operation in metering and sensor applications where periodic wake-up events are infrequent.
Can the R5F100GFANA#20 perform background data flash writes while executing application code from program memory?
Yes, the R5F100GFANA#20 supports Background Operation (BGO) for data flash. While rewriting 4–8 KB of data flash memory, the CPU can concurrently execute instructions from code flash - enabling seamless firmware updates, parameter logging, or calibration storage without interrupting real-time tasks.
What is the analog input capability of the R5F100GFANA#20, including resolution, channel count, and reference options?
The R5F100GFANA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and external AVREFP/AVREFM inputs, enabling precise measurements across the full 1.6–5.5 V supply range. An integrated temperature sensor is also accessible via dedicated ADC channel ANI25.
