Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DPLJFB#H2G | 100-pin LQFP, 384 KB flash, single CAN channel, same RL78/D1A core and peripheral set. | Limited to single-bus systems; insufficient for dual-CAN gateway or redundant motor control architectures. | Select when board space is constrained and only one CAN interface is required. |
| SPC560P50L5CEFAY | 32-bit Power Architecture core, 512 KB flash, dual CAN, but requires external oscillator and lacks integrated sigma-delta ADC. | Targets higher-performance automotive applications; lacks on-chip high-resolution ADC for direct current sensing. | Choose for ASIL-B functional safety compliance where RL78 does not meet certification requirements. |
Compared with R5F10DSKJFB#H2G, R5F10DPLJFB#H2G offers identical instruction set and toolchain compatibility but sacrifices one CAN channel and 128 KB flash, while SPC560P50L5CEFAY delivers higher compute throughput at the cost of increased external component count and no integrated precision ADC.

FAQ
What is the maximum operating frequency of the R5F10DSKJFB#H2G?
The R5F10DSKJFB#H2G operates at a maximum CPU clock frequency of 32 MHz, achieved using its on-chip high-speed oscillator or external crystal up to 20 MHz with PLL multiplication. This frequency enables execution of complex control algorithms within strict real-time deadlines, such as field-oriented control loops completing in under 50 µs on the R5F10DSKJFB#H2G.
Does the R5F10DSKJFB#H2G support both CAN 2.0A and CAN 2.0B protocols?
Yes, the R5F10DSKJFB#H2G supports full CAN 2.0B protocol compliance, including standard (11-bit) and extended (29-bit) identifier frames, as well as error confinement and bus-off recovery. Its dual CAN controllers operate independently and can be configured for mixed-mode operation-e.g., one channel in standard format and the other in extended format-without resource conflict on the R5F10DSKJFB#H2G.
How much data flash memory is integrated into the R5F10DSKJFB#H2G?
The R5F10DSKJFB#H2G integrates 8 KB of on-chip data flash memory, rated for 100,000 write/erase cycles and designed specifically for EEPROM emulation. This memory retains calibration coefficients, device-specific configuration parameters, and runtime logs across power cycles, eliminating external non-volatile storage requirements in designs using the R5F10DSKJFB#H2G.
What is the ADC resolution and effective number of bits (ENOB) of the R5F10DSKJFB#H2G?
The R5F10DSKJFB#H2G features a 24-bit sigma-delta ADC with typical ENOB of 18.2 bits at 100 SPS and 16.5 bits at 1 kSPS, measured under recommended decoupling and layout conditions. Its 20× oversampling and integrated digital filter deliver high-precision current and voltage measurements essential for closed-loop control in applications deploying the R5F10DSKJFB#H2G.
Is the R5F10DSKJFB#H2G qualified for automotive applications?
The R5F10DSKJFB#H2G is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial, office, and consumer applications-not automotive safety-critical systems. While it supports CAN and operates across –40°C to +85°C, it lacks AEC-Q100 qualification and functional safety certification (e.g., ISO 26262), so it should not be used in airbag controllers or ADAS modules requiring ASIL compliance, even though it functions reliably in non-safety automotive body modules.
