Overview
R5F10BGDLNA#G5 from Renesas Electronics is a 16-bit RL78/F13 microcontroller with CAN and LIN physical layer support, 48-pin LQFP package, 64 KB flash memory, 4 KB RAM, and operating voltage range of 2.7–5.5 V. It integrates a 32 MHz max CPU clock, 12-bit ADC (12 channels), 8-bit D/A converter, and hardware LIN bus controller - deployed in automotive body control modules requiring robust serial communication and mixed-signal processing.
For engineers reviewing the R5F10BGDLNA#G5 datasheet, R5F10BGDLNA#G5 pinout, R5F10BGDLNA#G5 application, or R5F10BGDLNA#G5 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts for automotive subsystem design, ECU firmware migration, and LIN/CAN gateway development.
Technical Context
The R5F10BGDLNA#G5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6 DMIPS/MHz performance and low-power SNOOZE mode (0.52 μA typical). It features dual voltage domains: EVDD/EVSS for analog peripherals (ADC, D/A, comparator) and VDD/VSS for digital logic, enabling independent power optimization.
Its on-chip communication includes one CAN controller compliant with ISO 11898-1 (CAN 2.0B), one LIN controller supporting LIN 2.2A/SAE J2602, and multiple UART/SPI/I²C interfaces. The device supports hardware CRC calculation, 16-bit watchdog timer, and on-chip debug interface via FINE v3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC core, 32 MHz max operation - enables deterministic real-time control with low interrupt latency. |
| Flash Memory | 64 KB on-chip flash with block erase and 100k write/erase cycles - sufficient for complex automotive firmware with OTA update capability. |
| RAM | 4 KB SRAM with retention in STOP mode - supports data logging and state preservation during sleep. |
| ADC | 12-bit successive approximation ADC, 12 input channels, ±1 LSB INL - suitable for precise sensor signal acquisition (e.g., temperature, pressure). |
| DAC | 8-bit voltage-output DAC, 1 channel, monotonic output - provides analog actuator drive without external components. |
| CAN Interface | ISO 11898-1 compliant CAN controller with 32 message objects and programmable bit timing - supports full CAN FD readiness via software configuration. |
| LIN Interface | Dedicated LIN controller with auto-baud detection, checksum generation/verification, and slave node response handling - eliminates host CPU overhead for LIN protocol stack. |
Pinout & Package
Package: 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including CAN_TX, CAN_RX, LIN_TX, LIN_RX, and ADC inputs. |
| P10–P17 | Port 1 bidirectional I/O | Supports external interrupt, key return, and timer capture/compare; P10/P11 serve as crystal oscillator connections (X1/X2). |
| P30–P34 | Port 3 bidirectional I/O | Includes dedicated LIN_SLP (sleep/wake) and CAN_STB (standby) pins - enables low-power network wake-up without MCU core activation. |
| VDD / VSS | Digital power supply / ground | Core logic domain (1.8–5.5 V); decoupling required within 10 mm of pins to ensure noise immunity in automotive environments. |
| EVDD / EVSS | Analog power supply / ground | Separate 2.7–5.5 V analog domain for ADC/DAC/comparator - isolation prevents digital switching noise from degrading analog accuracy. |
| RESET | Active-low reset input | Accepts external reset signal; internal power-on reset (POR) and low-voltage detection (LVD) also available - ensures reliable boot under battery fluctuation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CAN + LIN controllers | Single-chip solution for multi-protocol vehicle networks - reduces BOM count and PCB area vs. discrete transceivers + MCU combinations. |
| Hardware CRC accelerator | Performs CRC-16/CCITT and CRC-32 in one instruction cycle - accelerates firmware signature verification and message integrity checking. |
| SNOOZE mode operation | 0.52 μA typical current with RTC running and LIN wake-up enabled - extends battery life in always-on automotive modules (e.g., door modules). |
| On-chip D/A converter | 8-bit monotonic output with 1.5 V reference - drives analog actuators (e.g., LED dimming, valve biasing) without external DAC or op-amp. |
| FINE v3 debug interface | 2-pin single-wire debug with flash programming support - enables in-circuit debugging and field firmware updates without JTAG header space. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10BGLDNA#G5 | Same package and pinout; differs only in mask ROM content - no flash memory, factory-programmed firmware only. | Not suitable for field-upgradable systems; limited to fixed-function modules with no firmware customization. | Select only for cost-sensitive, high-volume modules where firmware is immutable and flash reprogramming is unnecessary. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, ASIL-B capable, but requires external CAN/LIN transceivers and higher BOM cost. | Targeted at safety-critical powertrain or chassis applications; over-spec for body electronics with stricter certification overhead. | Choose only when ISO 26262 ASIL-B compliance is mandated; otherwise, R5F10BGDLNA#G5 offers optimal balance of integration, cost, and qualification level. |
Compared with R5F10BGLDNA#G5, the R5F10BGDLNA#G5 enables field firmware updates and feature differentiation; compared with SPC560B50L5, it delivers lower system cost and simpler layout by integrating LIN/CAN controllers and analog peripherals - making it ideal for non-safety-critical automotive body electronics.

FAQ
What is the maximum operating frequency of the R5F10BGDLNA#G5?
The R5F10BGDLNA#G5 supports a maximum CPU clock frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is achievable across the full operating voltage range (2.7–5.5 V) and ambient temperature range (−40°C to +105°C), enabling real-time execution of LIN/CAN protocol stacks and sensor processing tasks without external clock conditioning.
Does the R5F10BGDLNA#G5 include an integrated CAN transceiver?
No, the R5F10BGDLNA#G5 integrates a CAN controller only - not a physical-layer transceiver. It requires an external CAN transceiver (e.g., TJA1042T/3) connected to P00 (CAN_TX) and P01 (CAN_RX) pins. This separation allows design flexibility in selecting transceivers with specific fault protection, wake-up sensitivity, or EMC performance.
Is the R5F10BGDLNA#G5 qualified for automotive applications?
Yes, the R5F10BGDLNA#G5 is AEC-Q100 qualified to Grade 2 (−40°C to +105°C), meeting reliability and stress-test requirements for automotive body electronics. Its dual power domains, LIN/CAN integration, and SNOOZE mode are specifically engineered for under-hood and cabin-mounted modules subject to thermal cycling and electrical noise.
What debug interface does the R5F10BGDLNA#G5 support?
The R5F10BGDLNA#G5 supports the FINE v3 single-wire debug interface using the P07 pin. This interface enables full in-circuit debugging, flash programming, and real-time trace without requiring a dedicated JTAG header - reducing PCB footprint and simplifying production programming for automotive Tier 2 suppliers.
Can the R5F10BGDLNA#G5 operate from a 3.3 V supply?
Yes, the R5F10BGDLNA#G5 operates across a wide voltage range of 2.7 V to 5.5 V, fully supporting 3.3 V nominal supply. At 3.3 V, it maintains full 32 MHz operation and all peripheral functionality, including ADC accuracy (±1 LSB INL) and LIN/CAN timing compliance - making it compatible with common 3.3 V automotive domain controllers.
