It features a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays, and operates across –40°C to +105°C industrial temperature range.
For engineers reviewing the R5F10DMJCJFB#56 datasheet, R5F10DMJCJFB#56 pinout, R5F10DMJCJFB#56 application, or R5F10DMJCJFB#56 equivalent, this device is selected for automotive body control modules, industrial PLC I/O units, and CAN-based sensor fusion nodes where mixed-signal integration, functional safety readiness, and extended temperature operation are required.
Technical Context
The R5F10DMJCJFB#56 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions and 3-stage pipeline execution. It integrates dual CAN controllers (CAN0/CAN1) compliant with ISO 11898-1:2015, each with 32 message objects, programmable bit timing, and loopback/self-test modes.
On-chip peripherals include a 12-bit successive-approximation ADC with hardware-triggered sampling, 16-bit multifunction timer unit (MTU) with complementary PWM output, and a dedicated low-power real-time clock (RTC) with calendar function. All peripherals are accessible via dedicated SFRs and support interrupt-driven operation with 32 priority levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DMECDSP#55 | Same RL78/D1A family, 80-pin LQFP, but with 384 KB flash, 24 KB RAM, and no CAN1 - only single CAN channel | Suitable for cost-sensitive CAN endpoints without need for bus redundancy or multi-network routing | Select when dual-CAN capability is unnecessary and flash/RAM requirements are lower |
| SPC560B50L3 | 32-bit Power Architecture MCU, 512 KB flash, single CAN 2.0B, AEC-Q100 Grade 2 (–40°C to +105°C), no integrated EEPROM emulation | Targets higher-performance automotive applications requiring complex math or larger code footprint; lacks RL78's ultra-low-power STOP mode | Choose for legacy Power Architecture toolchain compatibility or when 32-bit processing headroom is mandatory |
Compared with R5F10DMJCJFB#56, R5F10DMECDSP#55 reduces system cost by eliminating redundant CAN hardware but sacrifices network flexibility, while SPC560B50L3 offers greater computational throughput at the expense of higher active power and absence of hardware-assisted EEPROM emulation.

FAQ
What is the maximum operating frequency of the R5F10DMJCJFB#56?
The R5F10DMJCJFB#56 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal/resonator with PLL multiplication. This frequency is fully supported across the full –40°C to +105°C operating temperature range and 1.8–5.5 V supply voltage, enabling deterministic real-time response in time-critical control loops.
Does the R5F10DMJCJFB#56 support CAN FD?
No, the R5F10DMJCJFB#56 implements two CAN 2.0B controllers compliant with ISO 11898-1:2015, supporting standard and extended frames up to 1 Mbps, but does not support CAN FD data rates or flexible data-length frames. Its dual-CAN architecture is designed for legacy CAN network segmentation or redundancy-not high-bandwidth FD migration.
What debug interface does the R5F10DMJCJFB#56 use?
The R5F10DMJCJFB#56 uses Renesas' single-wire debug (SWD) interface compatible with E1 and E20 emulators. The debug port shares pin P10 and requires no dedicated debug header, enabling in-system programming and real-time trace without sacrificing GPIO count. Full SWD support includes breakpoints, watchpoints, and memory inspection via CS+ or e2 studio IDEs.
Is the R5F10DMJCJFB#56 qualified for automotive applications?
Yes, the R5F10DMJCJFB#56 is AEC-Q100 qualified (Grade 2: –40°C to +105°C) and designed for automotive body electronics. It includes functional safety features such as RAM parity, flash BIST, windowed WDT, and clock frequency monitoring aligned with ISO 26262 ASIL-B development requirements-though final system-level ASIL certification remains the responsibility of the end equipment integrator.
How much EEPROM emulation capacity is available on the R5F10DMJCJFB#56?
The R5F10DMJCJFB#56 provides 5 KB of dedicated data flash memory configured for EEPROM emulation, managed by Renesas' Flash Self-Programming Library (FSPL). This area supports byte-level read/write, automatic wear leveling, and guaranteed 100,000 write cycles - enabling reliable non-volatile storage of calibration data, device IDs, or operational logs without external serial EEPROM.
