Product details
Overview
R5F10DSLJFB#X6G from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 128-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, dual CAN 2.0B controllers (2 channels), and integrated 12-bit ADC with 32 channels. It operates at up to 32 MHz, supports low-power SNOOZE mode (0.42 µA), and targets automotive body control modules requiring functional safety support.
For engineers reviewing the R5F10DSLJFB#X6G datasheet, R5F10DSLJFB#X6G pinout, R5F10DSLJFB#X6G application, or R5F10DSLJFB#X6G equivalent, key selection criteria include dual-CAN interface capability, ASIL-B-ready peripheral consistency, 128-pin LQFP mechanical compatibility, and RL78/D1A family toolchain alignment (CS+ IDE, PG-FP5 programmer).
Technical Context
The R5F10DSLJFB#X6G implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiplication/division and bit manipulation. Its memory subsystem includes 512 KB on-chip flash with ECC protection, 32 KB RAM (including 4 KB data flash), and 8 KB ROM for bootloader functions.
Peripheral integration includes two independent CAN controllers compliant with ISO 11898-1:2015, a 12-bit ADC with hardware-triggered sampling and window comparison, 16-bit timer arrays (TMR0–TMR3) with dead-time insertion, and a dedicated LIN controller supporting both master and slave modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC CPU with 32 MHz max clock; enables deterministic real-time control with sub-100 ns interrupt latency. |
| Flash Memory | 512 KB with ECC and 100K write/erase cycles; supports in-application programming (IAP) and secure firmware updates. |
| RAM | 32 KB SRAM (including 4 KB data flash); sufficient for dual-CAN message buffering and real-time task stacks. |
| CAN Interfaces | Dual CAN 2.0B controllers (CAN0/CAN1); each supports 32 message objects, automatic retransmission, and bus-off recovery. |
| ADC | 12-bit resolution, 32-channel SAR ADC with ±1 LSB INL; supports simultaneous sampling across 2 groups for motor current sensing. |
| Operating Voltage | 1.6 V to 5.5 V supply range; allows direct connection to 3.3 V or 5 V automotive domains without level-shifting. |
| Low-Power Mode | SNOOZE mode draws 0.42 µA (typ.) with RTC running; enables battery-backed wake-up for periodic sensor polling. |
Pinout & Package
Package: 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DSKJFB#X6G | Same 128-pin LQFP package and RL78/D1A core, but with 384 KB flash and single CAN channel. | Lacks second CAN controller; suitable for non-gateway body control nodes where only one CAN bus is required. | Select when dual-CAN is unnecessary and cost reduction is prioritized over future firmware scalability. |
| R5F10DPLJFB#X6G | 100-pin LQFP variant with dual CAN, 384 KB flash, and identical peripheral set except reduced ADC channels (24 vs. 32). | Smaller footprint limits I/O count; appropriate for space-constrained modules with fewer analog sensors. | Choose for compact designs needing dual CAN but not requiring 32 ADC inputs or 512 KB flash headroom. |
Compared with R5F10DSKJFB#X6G and R5F10DPLJFB#X6G, the R5F10DSLJFB#X6G provides maximum on-chip resources-512 KB flash, 32 ADC channels, and dual CAN-making it optimal for high-integration automotive gateways where firmware complexity and sensor density demand headroom.

FAQ
What is the maximum operating frequency of the R5F10DSLJFB#X6G?
The R5F10DSLJFB#X6G operates at a maximum CPU clock frequency of 32 MHz. This speed is achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. The 32 MHz limit ensures timing compliance across all integrated peripherals-including dual CAN controllers and the 12-bit ADC-under worst-case voltage and temperature conditions specified in the datasheet.
Does the R5F10DSLJFB#X6G support ISO 26262 functional safety certification?
The R5F10DSLJFB#X6G includes hardware features aligned with ISO 26262 ASIL-B requirements, such as flash/RAM built-in self-test (BIST), lockstep-capable timers, voltage/frequency monitors, and error-correcting code (ECC) for memory. While Renesas provides safety manuals and FMEDA reports, final ASIL-B certification depends on system-level implementation-including software diagnostics, layout practices, and failure analysis-per customer-specific safety plans.
How many CAN interfaces does the R5F10DSLJFB#X6G support, and are they fully independent?
The R5F10DSLJFB#X6G supports two fully independent CAN 2.0B controllers (CAN0 and CAN1), each with its own message RAM, acceptance filters, error counters, and bus-off recovery logic. They operate concurrently without resource contention, enabling true dual-bus communication-for example, CAN0 for powertrain messaging and CAN1 for chassis network traffic-without requiring time-slicing or arbitration.
What development tools are officially supported for the R5F10DSLJFB#X6G?
Renesas officially supports the CS+ integrated development environment (IDE) with C compiler and debugger, the E2 emulator Lite for on-chip debugging, and the PG-FP5 Flash Memory Programmer for mass production programming. These tools provide full visibility into the R5F10DSLJFB#X6G's dual CAN registers, ADC configuration, and low-power mode transitions, and are validated against the RL78/D1A User's Manual Rev.1.20.
Is the R5F10DSLJFB#X6G pin-compatible with other RL78/D1A 128-pin variants like R5F10DSKJFB#X6G?
Yes, the R5F10DSLJFB#X6G is pin-compatible with other RL78/D1A 128-pin LQFP variants including R5F10DSKJFB#X6G and R5F10DSJJFB#X6G. All share identical pin assignments for power, ground, reset, debug, CAN, ADC, and general-purpose I/O. Differences lie in internal configuration-such as flash size and peripheral enablement-not pin function mapping-allowing drop-in replacement in existing PCB layouts when upgrading firmware capacity or feature set.
