FAQ

What is the maximum operating frequency of the R5F10BBELNA#G5?

The R5F10BBELNA#G5 supports a maximum system clock frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is achievable across the full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature, with timing margins verified per Renesas' AC characteristics table in the R01UH0368E hardware manual.

Does the R5F10BBELNA#G5 include a hardware LIN controller?

Yes, the R5F10BBELNA#G5 integrates a dedicated hardware LIN controller compliant with LIN 2.2A and SAE J2602 standards. It handles frame synchronization, header detection, checksum generation, and response timing autonomously - freeing the CPU from bit-level protocol management and ensuring deterministic latency under interrupt load.

What package type and dimensions does the R5F10BBELNA#G5 use?

The R5F10BBELNA#G5 is packaged in a 32-pin LSSOP (Low-profile Shrink Small Outline Package) measuring 7.6 mm × 5.6 mm with 0.65 mm lead pitch. It is RoHS-compliant, rated MSL-3, and features gull-wing leads compatible with standard reflow profiles per J-STD-020.

Can the R5F10BBELNA#G5 operate from a single 3.3 V supply?

Yes, the R5F10BBELNA#G5 operates fully across 1.6–5.5 V, including standard 3.3 V nominal supplies. At 3.3 V, it delivers full 32 MHz performance, supports all peripherals (ADC, D/A, timers, CAN, LIN), and maintains specified timing margins - eliminating need for voltage translation in mixed-voltage systems.

Is the R5F10BBELNA#G5 qualified for automotive applications?

Yes, the R5F10BBELNA#G5 is AEC-Q100 qualified for Grade 2 (-40°C to +105°C ambient), meeting automotive reliability and stress test requirements. Its integrated CAN/LIN controllers, fail-safe features (windowed WDT, BIST), and production traceability make it suitable for body electronics, chassis sensors, and non-safety-critical powertrain subsystems.
