Applications
| Industrial Sensor Node | Smart HVAC Controller |
|---|---|
Use Scenario: Battery-powered temperature/humidity/CO₂ sensor node transmitting data every 10 seconds via UART-to-LoRa module. IC Role / Device Role / Timing Role: Main system controller managing sensor polling, ADC conversion, data formatting, and low-power sleep/wake scheduling. Use Value: STOP mode current ≤0.25 μA extends 2×AA battery life beyond 5 years; integrated ADC eliminates external signal conditioning IC. |
Use Scenario: Wall-mounted HVAC thermostat with display, relay drivers, and ambient air quality monitoring. IC Role / Device Role / Timing Role: Central MCU coordinating fan speed control (PWM), temperature regulation (PID loop), and user interface responsiveness. Use Value: TAU timer arrays deliver precise 25 kHz PWM for brushless fan control; 12-bit ADC resolves 0.1°C temperature steps across full range. |

Use Scenario: Secondary safety monitor in infusion pump detecting occlusion, air-in-line, and motor stall via analog pressure and current sensing. IC Role / Device Role / Timing Role: Independent safety-critical monitor running separate firmware, validating primary controller output against hard-coded limits. Use Value: Parity-protected RAM and flash lock bits ensure runtime integrity; voltage monitor triggers immediate shutdown if supply drops below 1.6 V threshold. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F113GLLNA#W5 | Same die and pinout; differs only in tape-and-reel packaging (3,000 pcs/reel vs. 1,000 pcs/reel) | No functional difference; selected for high-volume SMT line compatibility | Choose #W5 for automated assembly requiring larger reels; #U5 suits prototyping and low-volume production. |
| R5F113GJLNA#U5 | Identical 48-pin LQFP package but with 64 KB flash and 6 KB RAM; same peripheral set and instruction set | Suitable where reduced code size and memory footprint are acceptable to lower BOM cost | Select #GJLNA#U5 when application firmware fits within 64 KB and cost sensitivity outweighs future scalability needs. |
Compared with R5F113GLLNA#U5, the #W5 variant offers identical functionality in higher-density packaging for factory automation, while the #GJLNA#U5 reduces flash and RAM capacity to lower unit cost-making it viable for fixed-function devices where firmware growth is constrained.

FAQ
What is the maximum operating frequency of the R5F113GLLNA#U5?
The R5F113GLLNA#U5 supports a maximum CPU clock frequency of 32 MHz. This can be achieved using the high-speed on-chip oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The device maintains full peripheral functionality and timing specifications across the entire 1.6 V to 5.5 V supply range at this speed.
Does the R5F113GLLNA#U5 include hardware debugging support?
Yes, the R5F113GLLNA#U5 integrates a full-featured on-chip debug interface compliant with Renesas E2 emulator protocol. It supports breakpoints, watchpoints, real-time variable monitoring, and flash programming via a 6-pin SWD-compatible connector - enabling zero-pin-debug during development without sacrificing I/O resources.
How many ADC input channels does the R5F113GLLNA#U5 support?
The R5F113GLLNA#U5 includes a 12-bit successive-approximation ADC with 12 selectable input channels (AN0–AN11), mapped across P10–P17 and P20–P23. All channels share a common sample-and-hold circuit and support hardware-triggered scanning sequences synchronized to timer events or external signals.
Is the R5F113GLLNA#U5 qualified for automotive applications?
No, the R5F113GLLNA#U5 is designated as a Standard-grade product per Renesas quality classification and is intended for industrial, consumer, and office equipment. It is not AEC-Q100 qualified and lacks the extended temperature range, enhanced ESD tolerance, and failure-in-time (FIT) reporting required for automotive use.
What power supply configurations are required for analog accuracy in the R5F113GLLNA#U5?
For optimal ADC and comparator performance, the R5F113GLLNA#U5 requires separate analog power domains: EVDD and EVSS must be decoupled with ≥1.0 μF ceramic capacitors near the REGC pin, and the internal regulator must be enabled. Digital VDD may be supplied independently at 1.6–5.5 V, but analog accuracy degrades if EVDD deviates more than ±2% from nominal 1.25 V.
