Overview
R5F10NMLDFB#10 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 64 KB flash memory, 4 KB RAM, and 48-pin LQFP package. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and integrates 12-bit ADC, 8-bit D/A converter, and hardware LIN transceiver for automotive body electronics control.
For engineers reviewing the R5F10NMLDFB#10 datasheet, R5F10NMLDFB#10 pinout, R5F10NMLDFB#10 application, or R5F10NMLDFB#10 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed LIN-compliant timing behavior, and real-world use cases in vehicle subsystems requiring low-power, single-wire serial communication and deterministic real-time response.
Technical Context
The R5F10NMLDFB#10 implements the RL78 CPU core with 3-stage pipeline, 16-bit ALU, and on-chip debug support via FINE v2. It features a dedicated LIN physical layer transceiver compliant with ISO 17987-4:2016, supporting baud rates from 1.2 kbps to 20 kbps with automatic sync-break detection and checksum validation.
Its peripheral set includes a 15-channel 12-bit ADC with programmable sampling time, an 8-bit D/A converter with internal reference, 16-bit timer arrays (TMR00–TMR03), and a real-time clock (RTC) with calendar function. All peripherals are accessible via the 16-bit data bus and share interrupt vectors mapped to the 32-level priority interrupt controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, no integrated LIN transceiver; requires external TJA1020 LIN PHY. | Targeted at higher-performance body controllers with CAN/LIN dual-bus architecture; not suitable for cost-sensitive single-LIN-node designs. | Select only when CAN coexistence and >100 DMIPS processing are required; adds 3 external components and increases layout complexity. |
| TLF35584ESV50 | Dedicated LIN system basis chip (SBC), no MCU core; integrates voltage regulator, watchdog, and LIN transceiver only. | Used as companion device to external MCU (e.g., R5F10NMLDFB#10 itself); cannot execute application code or manage sensors/actuators independently. | Choose when power management and fail-safe supervision are primary needs; must pair with separate MCU for full node functionality. |
Compared with SPC560B50L5 and TLF35584ESV50, the R5F10NMLDFB#10 delivers fully integrated LIN slave functionality in a single die-reducing BoM cost by $0.42/unit and eliminating inter-device timing skew that complicates ISO 17987-3 conformance testing.

FAQ
What LIN protocol versions does the R5F10NMLDFB#10 support?
The R5F10NMLDFB#10 supports LIN 2.2A and SAE J2602 protocols via its integrated hardware transceiver. It complies with ISO 17987-4:2016 physical layer specifications, including automatic sync-break detection, checksum calculation (classic and enhanced), and configurable baud rates from 1.2 kbps to 20 kbps. The R5F10NMLDFB#10 does not support LIN 2.1 or earlier legacy variants without firmware adaptation.
Does the R5F10NMLDFB#10 include a hardware watchdog timer?
Yes, the R5F10NMLDFB#10 includes a 16-bit independent watchdog timer (IWDT) with windowed operation mode and selectable timeout periods (16 ms to 2.1 s). It is clocked by a dedicated on-chip 150 kHz oscillator, ensuring reliable reset generation even if the main system clock fails. The IWDT must be refreshed within its window to prevent unintended reset, and its configuration is locked after initialization to prevent accidental modification during runtime.
Can the R5F10NMLDFB#10 operate from a 3.3 V supply while maintaining full LIN functionality?
Yes, the R5F10NMLDFB#10 operates across 1.6 V to 5.5 V, and LIN transceiver functionality is fully specified at 3.3 V. At this voltage, the LIN output driver meets ISO 17987-4 dominant/recessive voltage thresholds (dominant ≤ 1.0 V, recessive ≥ 8.0 V) with proper external termination (1 kΩ pull-up to battery). No configuration changes are needed-the R5F10NMLDFB#10 automatically adapts drive strength based on VDD level.
What is the maximum ADC sampling rate achievable with the R5F10NMLDFB#10?
The R5F10NMLDFB#10 achieves a maximum ADC conversion rate of 1.15 MSPS when using the fastest sampling clock (32 MHz system clock divided by 4 = 8 MHz ADC clock) and shortest sampling time setting (1 ADC clock cycle). This allows full 12-bit conversions every 860 ns, enabling real-time monitoring of fast-changing analog signals such as motor current ripple or switch debounce transients.
Is the R5F10NMLDFB#10 qualified for automotive applications under AEC-Q100?
Yes, the R5F10NMLDFB#10 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient operating temperature) and supports automotive reliability requirements including HTOL, ESD, and EMC testing per ISO 11452 and ISO 7637-2. Its RL78/F13 lineage is widely deployed in production automotive body control modules, and the R5F10NMLDFB#10 carries the same qualification documentation package as other members of the family.
