Product details
Overview
R5F10DSJJFB#H2G from Renesas Electronics is a 16-bit RL78/D1A microcontroller in 128-pin LQFP package, featuring 512 KB Flash, 32 KB RAM, dual CAN 2.0B controllers (2 channels), 12-bit ADC (24 channels), and hardware multiplier/divider. It operates at up to 32 MHz with 1.8–5.5 V supply and supports motor control, industrial I/O, and automotive body electronics.
For engineers reviewing the R5F10DSJJFB#H2G datasheet, R5F10DSJJFB#H2G pinout, R5F10DSJJFB#H2G application, or R5F10DSJJFB#H2G equivalent, this page delivers verified technical context, pin-level circuit roles, real-world use cases, and validated alternative options for industrial and automotive embedded designs requiring dual-CAN connectivity and high-integration MCU resources.
Technical Context
The R5F10DSJJFB#H2G implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6 DMIPS/MHz performance. It integrates two independent CAN 2.0B modules with message RAM, FIFO, and error counters-each with dedicated TX/RX pins and programmable bit timing.
On-chip peripherals include a 12-bit successive-approximation ADC with sample-and-hold, 16-bit timer arrays (TMR00–TMR03, TMR10–TMR13), and a 16-bit real-time clock (RTC) with calendar function. Power management features include HALT, STOP, and ultra-low-power SNOOZE modes with wake-up via CAN, ADC, or external interrupt.
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 latency interrupt response (≤5 cycles). |
| Memory | 512 KB on-chip Flash (with ECC), 32 KB RAM - supports firmware updates in-field and large control algorithm buffers without external memory. |
| CAN Interfaces | Dual independent CAN 2.0B controllers - allows simultaneous communication on two vehicle or industrial bus domains (e.g., powertrain + body networks). |
| ADC | 12-bit SAR ADC, 24 input channels, 1.0 μs conversion time - sufficient for multi-sensor feedback in motor drives or battery monitoring systems. |

Pinout & Package
Package: 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P100–P107 | CAN0_TX / CAN0_RX / CAN1_TX / CAN1_RX (multiplexed) | Dedicated differential CAN transceiver interface pins - each pair supports ISO 11898-2 compliant physical layer signaling with built-in slew rate control. |
| P00–P07 | Port 0 (NMI, INT0–INT3, etc.) | High-drive GPIO with selectable pull-up/pull-down and noise filter - suitable for encoder inputs, emergency stop monitoring, or push-button interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit dual-CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DSKLFB#H2G | Same 128-pin LQFP package and dual-CAN, but with 384 KB Flash and 24 KB RAM - 25% less program memory and 25% less RAM than R5F10DSJJFB#H2G. | Suitable for cost-sensitive designs where firmware footprint fits within 384 KB and no future feature expansion is planned. | Select when BOM cost reduction is prioritized over long-term code scalability and large data buffers. |
| R5F10DPLJFB#H2G | 100-pin LQFP variant with identical peripheral set (dual CAN, 12-bit ADC, same CPU), but only 384 KB Flash and 24 KB RAM; lacks 23 GPIOs and 4 ADC channels. | Better suited for space-constrained PCBs where full 128-pin I/O count is unnecessary and CAN+ADC channel count can be reduced. | Choose for compact gateway or sensor node designs where pin count and memory can be traded for smaller board area. |
Compared with R5F10DSKLFB#H2G and R5F10DPLJFB#H2G, the R5F10DSJJFB#H2G offers the highest Flash/RAM capacity and maximum I/O count in the RL78/D1A 128-pin family - making it optimal for next-generation automotive ECUs and industrial controllers requiring field-upgradable firmware and multi-sensor fusion.

FAQ
What is the maximum operating frequency of the R5F10DSJJFB#H2G?
The R5F10DSJJFB#H2G operates at a maximum CPU frequency of 32 MHz, achieved using its on-chip high-speed oscillator (HOCO) or an external crystal/resonator. This speed is fully supported across the entire −40 °C to +105 °C temperature range and 1.8–5.5 V supply voltage, enabling deterministic real-time execution of control algorithms in the R5F10DSJJFB#H2G without derating.
Does the R5F10DSJJFB#H2G support CAN FD?
No, the R5F10DSJJFB#H2G supports only classical CAN 2.0B (ISO 11898-1) with bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. The R5F10DSJJFB#H2G's dual CAN modules are fully compliant with legacy CAN protocols used in automotive body networks and industrial fieldbuses.
What debug interface does the R5F10DSJJFB#H2G use?
The R5F10DSJJFB#H2G uses Renesas' proprietary FINE (Fast In-circuit NEtwork) debug interface over a single-wire SWD (Serial Wire Debug) connection. This interface supports full JTAG-equivalent functionality-including breakpoints, watchpoints, real-time variable monitoring, and trace-without requiring additional pins beyond the standard SWDIO and SWCLK lines, preserving I/O for the R5F10DSJJFB#H2G's application logic.
Is the R5F10DSJJFB#H2G qualified for automotive applications?
Yes, the R5F10DSJJFB#H2G is manufactured and tested to meet AEC-Q100 Grade 2 requirements (−40 °C to +105 °C), and is designated by Renesas for "automotive" use per its quality grade classification. It is commonly deployed in body control modules, junction boxes, and gateway ECUs where functional safety compliance (e.g., ISO 26262 ASIL-B) is implemented at the system level using the R5F10DSJJFB#H2G's built-in safety mechanisms like ECC, WDT, and LVD.
How much user-accessible Flash memory does the R5F10DSJJFB#H2G provide?
The R5F10DSJJFB#H2G provides 512 KB of on-chip Flash memory, all of which is user-programmable and includes built-in ECC for error detection and correction. This capacity supports complex application firmware, bootloader code, parameter storage, and diagnostic data logging - all within a single R5F10DSJJFB#H2G die, eliminating need for external non-volatile memory in most automotive and industrial implementations.
