FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GHDFB#V0?
The R5F104GHDFB#V0 operates at up to 32 MHz and delivers 44 DMIPS performance per the RL78/G14 datasheet. This benchmark reflects execution speed under typical compiler-optimized code and confirms deterministic real-time capability for control loops requiring sub-100 µs response times. The R5F104GHDFB#V0 achieves this using its 3-stage pipeline RL78 core with high-speed on-chip oscillator calibration.
Does the R5F104GHDFB#V0 support LIN bus communication, and which peripheral handles it?
Yes, the R5F104GHDFB#V0 supports LIN bus communication through its UART channels - specifically UART0 and UART2, both compliant with LIN 2.2 physical layer requirements. The UART module includes automatic baud rate detection and LIN break detection logic. This capability is confirmed in the RL78/G14 datasheet section "Serial Interfaces" and applies directly to the R5F104GHDFB#V0 variant.
What are the memory resources allocated to the R5F104GHDFB#V0, and how is data flash utilized?
The R5F104GHDFB#V0 features 128 KB code flash, 8 KB data flash, and 16 KB RAM. The data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for logging or configuration updates. Its 1,000,000 write endurance (typ.) and 1.8–5.5 V rewrite voltage range make it suitable for field-updatable parameters in the R5F104GHDFB#V0.
Which package type and pin count does the R5F104GHDFB#V0 use, and what is its moisture sensitivity level?
The R5F104GHDFB#V0 uses a 48-pin LFQFP package with 0.5 mm pitch (RENESAS code PLQP0048KF-A), measuring 7 × 7 mm. Its moisture sensitivity level (MSL) is Level 3 per J-STD-020, requiring bake conditioning if exposed beyond floor life. This package is explicitly listed in Table 1-1 of the RL78/G14 datasheet for R5F104GHDFB#V0 under "48-pin plastic LFQFP".
How does the R5F104GHDFB#V0 achieve ultra-low power consumption, and what is its lowest active current draw?
The R5F104GHDFB#V0 achieves ultra-low power via multiple hardware states: HALT mode (66 μA/MHz), STOP mode (0.60 μA with RTC+LVD active), and SNOOZE mode for selective peripheral operation. Its lowest active current is 66 μA per MHz at 32 MHz (2.112 mA total), verified in the "Ultra-Low Power Consumption Technology" section of the RL78/G14 datasheet - a value directly applicable to the R5F104GHDFB#V0.
