For engineers reviewing the R5F113GLLNA#W5 datasheet, R5F113GLLNA#W5 pinout, R5F113GLLNA#W5 application, or R5F113GLLNA#W5 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed automotive-grade operating temperature (−40°C to +105°C), and direct alternative part comparisons for ECU design and replacement sourcing.
Technical Context
The R5F113GLLNA#W5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6 V to 5.5 V single-supply operation and ultra-low power modes (HALT, STOP, and SNOOZE). Its on-chip debug interface enables real-time trace and flash programming via SWD, while the integrated voltage regulator supplies internal logic at 1.8 V.
Peripheral integration includes a 16-bit timer array unit (TAU) with PWM output, watchdog timer (WDT), data flash memory (2 KB) with erase/write endurance of 100,000 cycles, and hardware CRC calculation engine - all aligned with ISO 26262 ASIL-B support requirements for automotive subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F113GLLNA#U0 | Same die, tape-and-reel packaging (vs. tray); identical electrical specs and pinout | No functional difference - intended for automated SMT assembly lines | Select #U0 for high-volume pick-and-place production; #W5 is tray-packaged for prototyping and low-volume builds |

FAQ
What is the maximum operating frequency of the R5F113GLLNA#W5?
The R5F113GLLNA#W5 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. This frequency enables real-time execution of LIN protocol stacks and sensor fusion algorithms while maintaining sub-100 μs interrupt latency - critical for responsive automotive control loops in the R5F113GLLNA#W5.
Does the R5F113GLLNA#W5 include a hardware LIN transceiver?
The R5F113GLLNA#W5 integrates a LIN protocol controller but does not include a physical-layer transceiver. It provides dedicated LIN TX/RX pins (P10/P11) that require an external LIN transceiver IC (e.g., TLE7259-3GE) for bus-level signaling. This architecture allows flexible voltage-level selection and EMC optimization - a key design consideration confirmed in the R5F113GLLNA#W5 hardware manual.
What is the endurance rating of the data flash memory in the R5F113GLLNA#W5?
The R5F113GLLNA#W5 features 2 KB of data flash memory rated for 100,000 erase/write cycles and 20-year data retention at 85°C. This specification is validated per JEDEC JESD22-A117 and supports robust storage of calibration parameters, fault logs, and user preferences - essential for automotive applications where field updates and long service life are required in the R5F113GLLNA#W5.
Is the R5F113GLLNA#W5 qualified to AEC-Q100 standards?
Yes, the R5F113GLLNA#W5 is AEC-Q100 qualified for Grade 2 (−40°C to +105°C ambient temperature) and complies with stress test requirements including HTOL, TC, HAST, and ESD. This qualification is documented in Renesas' official AEC-Q100 certificate for RL78/F15 devices and confirms suitability for under-dash automotive applications - a mandatory requirement for series production use of the R5F113GLLNA#W5.
Can the R5F113GLLNA#W5 operate from a 3.3 V supply?
Yes, the R5F113GLLNA#W5 operates across a 1.6 V to 5.5 V supply range, fully supporting 3.3 V nominal systems. At 3.3 V, it delivers guaranteed performance up to 24 MHz and maintains full peripheral functionality including ADC accuracy (±1 LSB INL), LIN timing compliance, and flash programming - verified in the R5F113GLLNA#W5 electrical characteristics table.
