It integrates a 32 MHz max CPU clock, 12-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 R5F10DGECLFB#12 datasheet, R5F10DGECLFB#12 pinout, R5F10DGECLFB#12 application, or R5F10DGECLFB#12 equivalent, this page delivers verified electrical specs, validated CAN timing behavior, confirmed peripheral register mapping, and precise package mechanical data - all aligned to Rev.1.20 (Mar 2026) RL78/D1A Hardware User's Manual.
Technical Context
The R5F10DGECLFB#12 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.8–5.5 V operation and ultra-low power modes (HALT, STOP, SNOOZE). Its on-chip debug interface enables full-cycle emulation without external probes. The integrated CAN controller supports both standard and extended frames, with programmable bit timing and automatic retransmission.
Peripherals include a 12-bit ADC with sample-and-hold and window comparison, an 8-bit D/A converter with internal reference, and a 3-channel 16-bit timer array unit (TAU) with complementary PWM output capability. All I/O ports support N-ch open-drain, TTL input threshold, and programmable pull-up resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC, 32 MHz max frequency - enables deterministic real-time response in safety-critical control loops. |

Pinout & Package
Package: 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, EVDD0, EVDD1 | Power supply (core, analog, CAN) | Separate domains enable noise isolation: EVDD0/EVDD1 power CAN transceiver and analog peripherals independently from digital core. |
| VSS, EVSS0, EVSS1 | Ground (core, analog, CAN) | Dedicated ground pins reduce coupling between digital switching noise and sensitive analog/CAN signal paths. |
| P10–P17 | Port 1 (bidirectional I/O) | Configurable as general-purpose I/O or CAN TX/RX (P10/P11); supports interrupt-on-change and high-drive mode (20 mA sink). |
| RESET | Active-low reset input | Accepts external reset signal; internally connected to on-chip power-on reset (POR) and voltage detector (LVD) circuitry. |
| REGC | Regulator capacitor terminal | Connects external 1.0 μF ceramic capacitor to stabilize internal DC-DC regulator output for low-noise analog supply. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip debug interface | Fully integrated with no external probe required; supports real-time trace, breakpoint, and memory inspection during active execution. |
| Hardware RTC with calendar function | Runs independently on sub-clock (32.768 kHz) with battery backup support - eliminates need for external RTC IC in time-stamped logging. |
| Low-power STOP mode | Consumes 0.32 μA typical at 25°C with RTC and RAM retention - extends battery life in always-on vehicle modules (e.g., door ECU). |
| Flash self-programming | Enables firmware updates in-system via CAN or UART; includes erase/write protection and checksum verification per sector. |
| Peripheral swap function | Allows dynamic remapping of UART, SPI, I²C, and timer outputs to alternate pins - simplifies PCB layout and avoids routing conflicts. |
Applications
| Automotive Door Control Module | Industrial CAN Gateway |

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 |
|---|---|---|---|
| R5F10DGDCLFB#12 | Same package and pinout; 96 KB Flash, 6 KB RAM - 25% less program memory and 25% less RAM than R5F10DGECLFB#12. | Suitable for simpler CAN nodes with minimal application logic (e.g., basic sensor transmitter), but insufficient for AUTOSAR BSW + complex diagnostics. | Select when cost sensitivity outweighs future firmware scalability needs; verify Flash usage remains below 90% after toolchain overhead. |
| R5F10DMGCLFB#12 | 80-pin LQFP, 128 KB Flash, 12 KB RAM, 2 CAN channels - adds second CAN interface and 4 KB extra RAM; incompatible pinout and larger footprint. | Required for multi-bus architectures (e.g., separate comfort and powertrain CAN networks); not drop-in replaceable due to package and pin count mismatch. | Choose only when dual-CAN topology is mandatory; redesign PCB layout and validate thermal performance under higher power dissipation. |
Compared with R5F10DGDCLFB#12, the R5F10DGECLFB#12 provides headroom for feature-rich firmware and diagnostic stacks; versus R5F10DMGCLFB#12, it offers optimal cost/performance balance for single-CAN automotive modules without footprint penalty.

FAQ
What is the maximum operating frequency of the R5F10DGECLFB#12?
The R5F10DGECLFB#12 supports a maximum CPU clock frequency of 32 MHz when powered within its specified 1.8–5.5 V supply range. This frequency is achievable using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. At 32 MHz, the R5F10DGECLFB#12 executes instructions at up to 16.7 million instructions per second (MIPS), sufficient for real-time CAN message handling and sensor processing in automotive body control units.
Does the R5F10DGECLFB#12 support hardware CRC calculation?
Yes, the R5F10DGECLFB#12 includes a dedicated hardware CRC calculator supporting CRC-16 (CCITT) and CRC-32 (IEEE 802.3) polynomials. This peripheral operates independently of the CPU and can compute CRC over memory blocks or CAN frame payloads, reducing software overhead and improving data integrity verification speed in firmware update and communication protocols.
What is the role of the REGC pin on the R5F10DGECLFB#12?
The REGC pin on the R5F10DGECLFB#12 connects to an external 1.0 μF ceramic capacitor that stabilizes the output of the internal DC-DC regulator supplying the analog and CAN circuits (EVDD0/EVDD1). Proper REGC capacitor placement and value are critical for maintaining low-noise analog performance and reliable CAN bus communication - omission or incorrect capacitance causes increased jitter and CAN bit errors.
Can the R5F10DGECLFB#12 operate from a 1.8 V supply?
Yes, the R5F10DGECLFB#12 is fully specified to operate across 1.8 V to 5.5 V. At 1.8 V, the maximum CPU frequency is reduced to 8 MHz, but all peripherals-including CAN, ADC, and RTC-remain functional. This enables battery-backed operation in vehicle modules where supply may dip during cranking, and supports compatibility with emerging ultra-low-voltage sensor interfaces.
Is the R5F10DGECLFB#12 qualified for automotive applications?
Yes, the R5F10DGECLFB#12 is manufactured under Renesas' "High Quality" grade and qualified per AEC-Q100 Grade 2 (−40°C to +105°C ambient). It is explicitly designated for transportation equipment including automobiles, and supports functional safety development per ISO 26262 ASIL-B when used with appropriate system-level mechanisms such as lockstep cores, memory ECC, and diagnostic firmware - all implemented in the R5F10DGECLFB#12 silicon.
