The R5F113GLKNA#U5 supports a maximum CPU clock frequency of 32 MHz using its on-chip high-speed oscillator or an external crystal/resonator. This frequency is achievable across the full 1.6 V to 5.5 V supply range and at ambient temperatures from −40°C to +85°C, as specified in the RL78/F15 Electrical Characteristics section of the Hardware Manual Rev.1.10.
Does the R5F113GLKNA#U5 include on-chip debug capability?
Yes, the R5F113GLKNA#U5 integrates a full-speed Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It supports real-time program execution control, memory/register access, flash programming, and trace via a 4-pin connection (SWCLK, SWDIO, RESET, VDD), eliminating the need for external debug probes during development.
What ADC resolution and channel count does the R5F113GLKNA#U5 support?
The R5F113GLKNA#U5 includes a single 12-bit successive-approximation ADC with 12 analog input channels (AN0–AN11), configurable for single-ended or differential input modes. Conversion time is 1.0 µs at maximum clock rate, and hardware triggers from TAU timers ensure precise sampling synchronization without CPU overhead.
Is the R5F113GLKNA#U5 qualified for automotive applications?
No, the R5F113GLKNA#U5 is designated as a "Standard" quality grade device per Renesas' classification and is intended for industrial, consumer, and office equipment - not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature range (−40°C to +125°C), or ISO 26262 support required for automotive deployment.
What package type and pin count does the R5F113GLKNA#U5 use?
The R5F113GLKNA#U5 uses a 48-pin QFN package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is documented in Section 1.5.5 ("RL78/F15 Pin Configuration for 48-pin Products") and Section 2.1.5 ("RL78/F15 48-pin products") of the RL78/F15 Hardware Manual Rev.1.10.
