Product details
Overview
R5F10DMGCJFB#12 from Renesas Electronics is an 80-pin RL78/D1A 16-bit microcontroller with integrated CAN 2.0B controller, 256 KB flash memory, 20 KB RAM, and operating voltage range of 1.6–5.5 V. It features a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays (TAU), and low-power SNOOZE mode for battery-powered industrial control applications.
For engineers reviewing the R5F10DMGCJFB#12 datasheet, R5F10DMGCJFB#12 pinout, R5F10DMGCJFB#12 application, or R5F10DMGCJFB#12 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases in CAN-based motor control and sensor aggregation, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The R5F10DMGCJFB#12 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiplication/division and bit manipulation. It integrates dual CAN controllers (CAN0/CAN1) compliant with ISO 11898-1:2015, each with 32 message objects and programmable FIFOs.
On-chip peripherals include a 12-bit ADC with ±1 LSB INL, 16-bit TAU with dead-time insertion for motor gate drive, and a hardware multiplier unit delivering 1-cycle 16×16-bit multiply. Power management supports five low-power modes-HALT, STOP, SNOOZE, DEEPSTOP, and ULTRADEEPSTOP-with wake-up latency as low as 3.5 µs from SNOOZE.
Key Specifications

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 |
|---|---|---|---|
| R5F10DMECJFB#12 | Same 80-pin LQFP package, identical peripheral set, but 192 KB flash and 16 KB RAM - 25% less program/data space. | Suitable for cost-sensitive designs where firmware size remains under 192 KB and runtime data fits in 16 KB. | Select when BOM cost reduction is prioritized and feature set matches; no PCB change required. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB flash, single CAN 2.0B, no SNOOZE mode - higher performance but larger footprint and power envelope. | Better suited for complex diagnostics and multi-protocol gateways requiring AUTOSAR stack support. | Choose only if 32-bit processing, ASIL-B compliance, or AUTOSAR compatibility are mandatory; requires new layout and toolchain migration. |
Compared with R5F10DMGCJFB#12, R5F10DMECJFB#12 offers identical pinout and peripheral timing but reduced memory - ideal for scaled-down variants; SPC560B50L5 delivers higher compute throughput at the cost of power, size, and software ecosystem complexity.

FAQ
What is the maximum operating frequency of the R5F10DMGCJFB#12?
The R5F10DMGCJFB#12 supports a maximum CPU clock frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is achievable across the full 1.6–5.5 V supply range and ambient temperature of –40°C to +85°C, enabling deterministic execution of real-time control loops with sub-microsecond timing resolution.
Does the R5F10DMGCJFB#12 support CAN FD?
No, the R5F10DMGCJFB#12 implements two CAN 2.0B controllers compliant with ISO 11898-1:2015, supporting standard and extended frame formats up to 1 Mbps. It does not support CAN FD data rates or flexible data-length payloads; for CAN FD capability, consider Renesas' RA6T2 or RH850/F1K families instead.
What debug interface does the R5F10DMGCJFB#12 use?
The R5F10DMGCJFB#12 uses Renesas' single-wire Fine (Fast In-circuit Emulator) debug interface, accessible via the P00 pin. This interface supports full-speed debugging, flash programming, and real-time trace without requiring a dedicated JTAG header, reducing PCB footprint and simplifying production test access.
Is the R5F10DMGCJFB#12 qualified for automotive applications?
The R5F10DMGCJFB#12 is rated for industrial temperature range (–40°C to +85°C) and classified as "Standard" grade per Renesas documentation. While widely used in automotive body electronics, it is not AEC-Q100 qualified; for automotive safety-critical systems, Renesas recommends the RL78/F14 or RH850 families with formal AEC-Q100 certification.
How much EEPROM-equivalent functionality does the R5F10DMGCJFB#12 provide?
The R5F10DMGCJFB#12 does not include dedicated EEPROM, but its 256 KB flash supports up to 100,000 write/erase cycles with hardware-assisted wear leveling via Renesas' Data Flash library. This enables emulated EEPROM functionality for storing calibration data, device IDs, and configuration parameters with guaranteed endurance matching industrial EEPROM requirements.
