Product details
Overview
R5F10NPLDFB#50 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with LIN bus interface, 64 KB flash memory, 4 KB RAM, and 64-pin LQFP package. It integrates a 32 MHz max CPU clock, 12-bit ADC (12 channels), 8-bit D/A converter, and hardware LIN transceiver for automotive body electronics control. It operates from 2.4 V to 5.5 V and supports -40°C to +105°C industrial temperature range.
For engineers reviewing the R5F10NPLDFB#50 datasheet, R5F10NPLDFB#50 pinout, R5F10NPLDFB#50 application, or R5F10NPLDFB#50 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed LIN-compliant timing behavior, and real-world automotive subsystem integration guidance - all specific to the R5F10NPLDFB#50 variant within the RL78/F13 (LIN-incorporated) family.
Technical Context
The R5F10NPLDFB#50 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.62 μs minimum instruction cycle at 32 MHz. It includes on-chip debug functionality via single-wire SWD interface and a dedicated LIN physical layer compliant with ISO 17987-4:2016 Class B requirements.
Its peripheral set features a 15-channel event link controller for deterministic interrupt chaining, a 16-bit multifunction timer array (with dead-time insertion), and independent watchdog and clock frequency accuracy measurement (CFAM) circuits - all operating under a dual-voltage domain (AVDD/EVDD) for analog/digital isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC core with 32 MHz max operation - enables deterministic real-time control in LIN node applications without external clock source. |
| Flash Memory | 64 KB on-chip flash with background operation (BGO) - supports firmware updates over LIN without halting application execution. |
| RAM | 4 KB on-chip RAM with parity error detection - ensures data integrity in safety-critical body control modules. |
| ADC | 12-bit successive approximation ADC with 12 input channels and 1.1 μs conversion time - suitable for precise sensor monitoring (e.g., cabin temperature, seat position). |
| LIN Interface | Dedicated hardware LIN controller + integrated transceiver (ISO 17987-4 Class B) - eliminates need for external LIN PHY and reduces BOM count by one IC. |
| Operating Voltage | 2.4 V to 5.5 V supply range - compatible with automotive battery voltage fluctuations including cold-crank (down to 2.4 V). |
| Temperature Range | -40°C to +105°C ambient - qualified for under-hood and interior automotive locations per AEC-Q100 Grade 2. |
Pinout & Package
Package: 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P100–P107 | Port 10 (bidirectional I/O) | Configurable as LIN TX/RX pins (P100 = LIN_TX, P101 = LIN_RX) with internal pull-up/down and slew-rate control for EMI suppression. |
| VDD, EVDD0, EVDD1 | Power supply inputs | Separate digital (VDD), analog (EVDD0), and LIN transceiver (EVDD1) supplies - enable noise isolation between domains. |
| VSS, EVSS0, EVSS1 | GND returns | Dedicated ground planes per supply domain reduce coupling of switching noise into analog/LIN paths. |
| RESET | Active-low reset input | Accepts external reset signal or internal power-on reset (POR)/voltage monitor (LVD) assertion - ensures safe initialization during brown-out. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN-node microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NLGDFB#50 | Same RL78/F13 (LIN) family, but 48 KB flash / 3 KB RAM - reduced code/data capacity. | Suitable for simpler LIN nodes with fewer features (e.g., basic mirror control only). | Select when firmware size is ≤40 KB and RAM usage stays below 2.5 KB to reduce cost without sacrificing LIN compliance. |
| SPC560B50L5 | 32-bit Power Architecture MCU with CAN+LIN, 512 KB flash, no integrated LIN PHY - requires external transceiver. | Targeted at higher-tier body domain controllers requiring CAN backbone connectivity alongside LIN subnets. | Choose when system architecture mandates CAN-LIN gateway functionality or >100 KB firmware footprint - not a drop-in replacement. |
Compared with R5F10NPLDFB#50, R5F10NLGDFB#50 offers identical peripheral timing and LIN electrical behavior but less memory headroom, while SPC560B50L5 provides broader network capability at the cost of increased BOM complexity and no integrated LIN PHY.

No external LIN transceiver IC is required, reducing bill-of-materials count and PCB area for LIN slave nodes.
What is the flash memory endurance and data retention specification for the R5F10NPLDFB#50?
The R5F10NPLDFB#50 guarantees 10,000 write/erase cycles for its 64 KB on-chip flash memory and 20-year data retention at +85°C ambient temperature. These values are validated per JEDEC JESD22-A117 and apply to standard erase/write operations without special wear-leveling firmware.
Which development tools are officially supported for the R5F10NPLDFB#50?
Renesas officially supports the E2 Emulator Lite and E2 Emulator for debugging the R5F10NPLDFB#50, along with the CS+ IDE and e2 studio toolchains.
