Overview
R5F10NMLDFB#50 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 64 KB flash memory, 4 KB RAM, and 48-pin QFP package. It operates at up to 32 MHz, supports 10-bit ADC (12 channels), and integrates a 16-bit timer array unit (TAU) and real-time clock (RTC). It targets automotive body electronics and industrial control nodes requiring reliable serial communication and low-power operation.
For engineers reviewing the R5F10NMLDFB#50 datasheet, R5F10NMLDFB#50 pinout, R5F10NMLDFB#50 application, or R5F10NMLDFB#50 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed LIN protocol compliance, and direct alternative part comparisons for automotive-grade embedded design.
Technical Context
The R5F10NMLDFB#50 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V supply range and ultra-low power modes (HALT, STOP, SNOOZE) down to 0.52 µA in deep standby. Its on-chip LIN controller complies with LIN 2.2A/SAE J2602 and supports automatic baud rate detection and slave node response timing.
It integrates a 10-bit successive approximation ADC with internal reference (1.45 V), programmable gain amplifier (PGA) on selected channels, and hardware-based CRC calculation unit for firmware integrity verification. The TAU supports input capture, output compare, PWM generation, and encoder interface functions across multiple channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NLGDFB#50 | Same RL78/F13 family, 48-pin LQFP, but with 32 KB flash and no PGA on ADC inputs. | Suitable for cost-sensitive LIN nodes where sensor signal levels exceed 1 V and external amplification is acceptable. | Select when flash requirement ≤32 KB and analog front-end complexity allows discrete signal conditioning. |
| SPC560B50L5 | 32-bit Power Architecture MCU, 512 KB flash, CAN-only interface, no native LIN support. | Requires external LIN transceiver and software stack; targets higher-performance engine control modules. | Choose only if CAN+LIN hybrid networking is required and existing SPC5 ecosystem integration justifies higher BOM cost and power. |
Compared with R5F10NMLDFB#50, R5F10NLGDFB#50 reduces flash capacity and removes PGA capability-making it viable for simpler LIN slaves-but SPC560B50L5 introduces architectural complexity and external component dependencies unsuitable for compact, low-cost body electronics.

What are the power supply requirements for the R5F10NMLDFB#50?
The R5F10NMLDFB#50 operates from a single 1.6 V to 5.5 V supply across VDD, with separate EVDD0/EVDD1 pins for analog domain regulation. It requires external 1 µF ceramic capacitors on VDD and REGC pins, and decoupling capacitors (0.1 µF) near each VDD/VSS pair. The device meets AEC-Q100 Grade 2 requirements (-40°C to +105°C ambient) under these conditions.
How much flash and RAM memory does the R5F10NMLDFB#50 provide?
The R5F10NMLDFB#50 includes 64 KB of on-chip flash memory with background operation (BGO) support and 4 KB of SRAM. Flash supports up to 100,000 write/erase cycles and retains data for 20 years at +85°C. SRAM maintains full contents in STOP mode with RTC active, enabling fast wake-up and state recovery in battery-powered applications.
Is the R5F10NMLDFB#50 qualified for automotive applications?
Yes, the R5F10NMLDFB#50 is AEC-Q100 Grade 2 qualified (-40°C to +105°C) and designed for automotive body electronics including door modules, seat controls, and HVAC actuators.
