FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FCGFP#V0?
The R5F100FCGFP#V0 operates up to 32 MHz with a high-speed on-chip oscillator accurate to ±1.0% over -40°C to +105°C. At this frequency, it achieves 41 DMIPS - sufficient for real-time motor control, sensor fusion, and protocol stack execution without external acceleration. Its minimum instruction time is 0.03125 μs in high-speed mode, confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100FCGFP#V0 support LIN bus communication natively?
Yes, the R5F100FCGFP#V0 supports LIN 2.2-compliant communication through its UART peripherals with dedicated hardware features including break detection, sync field generation, and checksum calculation. This eliminates the need for external LIN transceivers in basic implementations and is documented in Section 1.1 "Serial interface" of the R01DS0131EJ0380 datasheet.
What are the memory resources allocated to the R5F100FCGFP#V0?
The R5F100FCGFP#V0 integrates 96 KB of on-chip code flash memory, 8 KB of data flash memory (rated for 1,000,000 write cycles), and 8 KB of RAM. The data flash supports background operation (BGO), allowing code execution during rewrites - a key capability confirmed in Table 1-1 and Section 1.1 "Code flash memory" and "Data Flash Memory" of the R01DS0131EJ0380 datasheet.
How does the R5F100FCGFP#V0 achieve ultra-low-power operation in battery-powered systems?
The R5F100FCGFP#V0 achieves ultra-low-power operation via three dedicated modes: HALT (0.57 μA with RTC + LVD active), STOP, and SNOOZE. Its 1.6–5.5 V wide supply range and on-chip voltage detector (LVD) with 14 selectable levels enable reliable brown-out protection and wake-on-event functionality - critical for multi-year battery life in remote sensors, as specified in Section 1.1 "Ultra-low power consumption technology" of R01DS0131EJ0380.
Is the R5F100FCGFP#V0 qualified for industrial temperature operation?
Yes, the R5F100FCGFP#V0 carries the 'G' suffix denoting Industrial grade with guaranteed operation from -40°C to +105°C ambient temperature. This qualification is explicitly defined in Figure 1-1 "Part Number, Memory Size, and Package of RL78/G13" and confirmed in Table 1-1 ordering part number listings under "Fields of Application" in the R01DS0131EJ0380 datasheet.
