FAQ
What is the maximum operating frequency and corresponding performance of the R5F100PFDFB#30?
The R5F100PFDFB#30 operates at up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling adaptive performance/power tuning in battery-constrained deployments.
Does the R5F100PFDFB#30 support LIN bus communication, and how is it implemented?
Yes, the R5F100PFDFB#30 supports LIN bus communication through its UART peripherals, which are compliant with LIN 2.1 and SAE J2602 standards. The UART modules include hardware LIN break detection, sync field handling, and checksum calculation - allowing direct connection to LIN transceivers without software bit-banging, reducing CPU load in automotive body electronics and industrial networks.
What are the data retention and endurance specifications for the on-chip data flash in the R5F100PFDFB#30?
The R5F100PFDFB#30 integrates 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with data retention exceeding 20 years at +85°C. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash - critical for reliable firmware updates and parameter storage in mission-critical industrial controllers.
How does the R5F100PFDFB#30 manage power in low-duty-cycle applications like wireless sensors?
The R5F100PFDFB#30 achieves ultra-low power consumption via multiple hardware states: HALT mode (0.23 μA), STOP mode (0.57 μA with RTC + LVD active), and SNOOZE mode for selective peripheral wake-up. Combined with programmable voltage detector (LVD) interrupt levels and automatic clock gating, it enables multi-year battery life in intermittent-sensing applications without compromising responsiveness.
Is the R5F100PFDFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100PFDFB#30 is pin-compatible with all RL78/G13 devices in the 100-pin LFQFP package (FB suffix), including R5F100PGDFB#30, R5F100PHDFB#30, and R5F101PFDFB#30.
