Product details
Overview
R5F10DGDJFB#V2 from Renesas Electronics is a 16-bit RL78/D1A microcontroller with CAN interface, 64 KB flash memory, 4 KB RAM, and 48-pin LQFP package. It integrates a 32 MHz max CPU clock, 10-bit ADC (24 channels), 8-bit D/A converter, and hardware real-time clock - designed for automotive body electronics and industrial control nodes requiring robust serial communication and low-power operation.
For engineers reviewing the R5F10DGDJFB#V2 datasheet, R5F10DGDJFB#V2 pinout, R5F10DGDJFB#V2 application, or R5F10DGDJFB#V2 equivalent, key selection criteria include CAN 2.0B compliance, 1.8–5.5 V operating voltage range, 192 KB max program memory address space, and support for on-chip debug via FINE v3 interface - all confirmed in the RL78/D1A Hardware User's Manual Rev.1.10.
Technical Context
The R5F10DGDJFB#V2 implements the RL78 CPU core with 16-bit CISC architecture, supporting 16/32-bit instructions and 16-level priority interrupt nesting. It features dual-voltage domain design (EVDD/EVSS for analog peripherals, SMVDD/SMVSS for digital logic) and integrated voltage regulator for single-supply operation.
Its peripheral set includes one CAN controller (with 32 message objects and FIFO mode), 8-channel 16-bit timer array unit (TAU), watchdog timer (WDT), and low-power modes (HALT, STOP, SNOOZE) enabling sub-1 μA standby current. All peripherals are memory-mapped and accessible via dedicated SFRs defined in the RL78 instruction set.
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 1-cycle instruction execution for most instructions. |
| Flash Memory | 64 KB on-chip flash with 100 k-cycle endurance and 10-year data retention - supports field firmware updates without external memory. |
| RAM | 4 KB on-chip RAM - sufficient for stack, heap, and real-time data buffers in CAN-based sensor node applications. |
| CAN Interface | One CAN 2.0B-compliant controller with 32 message objects and programmable bit timing - meets ISO 11898-1 for automotive network integration. |
| ADC | 10-bit successive approximation ADC with 24 input channels and 1.0 μs conversion time - supports simultaneous sampling of multiple sensors in motor control feedback loops. |
| Operating Voltage | 1.8 V to 5.5 V - allows direct interfacing with 3.3 V and 5 V logic systems and battery-powered operation down to single-cell Li-ion (3.0 V typical). |
| Package | 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) - compatible with standard surface-mount assembly processes and IPC-7351B footprint. |
Pinout & Package
48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 I/O (multiplexed) | 8-bit general-purpose bidirectional port with selectable pull-up, interrupt capability, and alternate functions including UART0 TX/RX and I²C SCL/SDA. |
| P10–P17 | Port 1 I/O (multiplexed) | 8-bit port supporting CAN0 TX/RX, timer output compare, and A/D trigger inputs - critical for CAN node signal routing and timing synchronization. |
| VDD, EVDD0, SMVDD0 | Power supply pins | Dual-domain supply: EVDD0 powers analog peripherals (ADC, DAC, comparator); SMVDD0 powers digital logic - enables independent noise isolation and voltage scaling. |
| VSS, EVSS0, SMVSS0 | GND pins | Separate analog/digital ground returns prevent coupling noise into sensitive ADC measurements and CAN transceiver reference. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external reset IC or microcontroller supervisory signal - ensures reliable initialization after power-on or brownout. |
| REGC | Voltage regulator capacitor terminal | Connects external 1.0 μF ceramic capacitor to stabilize internal LDO output - mandatory for stable 1.8 V core voltage generation from higher input rails. |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Protocol gateway translating pulse-count events into standardized CAN frames with time-stamped payload. Use Value: Hardware RTC and 32-message CAN object buffer ensure accurate event timestamping and guaranteed delivery even during transient bus errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DGCJFB#V2 | Same package and pinout; lacks CAN controller - only 24 KB flash and no CAN peripheral. | Suitable for non-networked control tasks (e.g., standalone motor driver) where CAN is unnecessary. | Select when CAN functionality is not required and cost reduction is prioritized over communication flexibility. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, dual CAN, but requires external oscillator and higher supply voltage (3.3 V only). | Targeted at ASIL-B automotive safety applications with stricter qualification requirements. | Choose for safety-critical systems needing ISO 26262 support - not drop-in compatible due to architecture, pinout, and power constraints. |
Compared with R5F10DGDJFB#V2, R5F10DGCJFB#V2 reduces system cost by removing CAN hardware but sacrifices network interoperability, while SPC560B50L5 offers higher performance and safety certification at the expense of design complexity, PCB redesign, and increased BOM cost.

FAQ
What is the maximum operating frequency of the R5F10DGDJFB#V2?
The R5F10DGDJFB#V2 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal up to 20 MHz with PLL multiplication. This frequency is validated across the full 1.8–5.5 V operating voltage range and industrial temperature grade (–40°C to +85°C), as specified in the RL78/D1A Hardware User's Manual Rev.1.10.
Does the R5F10DGDJFB#V2 include an integrated CAN transceiver?
No, the R5F10DGDJFB#V2 contains only a CAN controller compliant with ISO 11898-1. An external CAN transceiver (e.g., TJA1042 or SN65HVD230) must be used to drive the physical bus. The R5F10DGDJFB#V2 provides dedicated CAN0_TX and CAN0_RX pins that connect directly to the transceiver's TXD and RXD lines - confirmed in Section 1.4.2 and Figure 1.15 of the RL78/D1A Hardware User's Manual.
What is the purpose of the REGC pin on the R5F10DGDJFB#V2?
REGC is the external capacitor connection terminal for the on-chip voltage regulator. A 1.0 μF ceramic capacitor must be placed between REGC and VSS to stabilize the internal LDO output that supplies the 1.8 V core voltage. Omitting this capacitor causes unstable operation or failure to boot - detailed in Section 2.2.20 and Figure 2.1 of the RL78/D1A Hardware User's Manual Rev.1.10.
Can the R5F10DGDJFB#V2 operate from a single 3.3 V supply?
Yes, the R5F10DGDJFB#V2 operates across 1.8 V to 5.5 V, so 3.3 V is fully supported. At 3.3 V, it delivers full 32 MHz performance with all peripherals active. The dual-domain power architecture (EVDD/SMVDD) allows analog and digital sections to share the same supply rail while maintaining noise isolation through separate ground paths - verified in Section 1.3 and Table 1.1 of the RL78/D1A datasheet.
How many ADC channels does the R5F10DGDJFB#V2 support, and what is their resolution?
The R5F10DGDJFB#V2 supports 24 analog input channels with a 10-bit successive approximation ADC. Conversion time is 1.0 μs per sample, and the ADC includes built-in scan mode, window comparison, and hardware trigger linkage to timers and interrupts - all documented in Section 2.1.6 and Chapter 13 of the RL78/D1A Hardware User's Manual Rev.1.10.
