Renesas R5F10DMGCJFB#56

Overview

R5F10DMGCJFB#56 from Renesas Electronics is an 80-pin RL78/D1A 16-bit microcontroller with integrated CAN 2.0B controller, 128 KB flash memory, 8 KB RAM, and operating voltage range of 2.7–5.5 V. It features a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays, and operates across –40°C to +85°C industrial temperature range. It is designed for real-time control in automotive body electronics and industrial networked sensors.

For engineers reviewing the R5F10DMGCJFB#56 datasheet, R5F10DMGCJFB#56 pinout, R5F10DMGCJFB#56 application, or R5F10DMGCJFB#56 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), on-chip debug interface (FINE), low-power STOP mode current (0.52 µA), and support for I²C, UART, and LIN physical layer via software emulation.

Technical Context

The R5F10DMGCJFB#56 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiplication/division and bit manipulation. Its peripheral set includes two independent CAN controllers (CAN0/CAN1), each with 32 message objects and programmable acceptance filtering.

It integrates a 12-bit successive-approximation ADC with sample-and-hold, configurable trigger sources (timer, external pin, software), and conversion time as low as 1.1 µs. The MCU supports three low-power modes-HALT, STOP, and SNOOZE-with wake-up capability from CAN bus activity, external interrupts, or RTC alarm.

FAQ

What is the maximum operating frequency of the R5F10DMGCJFB#56?

The R5F10DMGCJFB#56 supports a maximum CPU clock frequency of 32 MHz when powered at 2.7–5.5 V. This is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator up to 20 MHz with PLL multiplication. At 32 MHz, the instruction cycle time is 31.25 ns, enabling fast real-time response for time-critical CAN message handling and control loops.

Does the R5F10DMGCJFB#56 support hardware CAN FD?

No, the R5F10DMGCJFB#56 implements CAN 2.0B only, with support for standard (11-bit) and extended (29-bit) identifiers and bit rates up to 1 Mbps. It does not include CAN FD features such as flexible data-length or faster bit rates beyond 1 Mbps. For CAN FD applications, consider Renesas' RA6T2 or RH850/F1K series instead.

How many CAN controllers does the R5F10DMGCJFB#56 integrate?

The R5F10DMGCJFB#56 integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each with its own message RAM (32 objects), acceptance filter, and error counter. They operate concurrently and can be configured for different bit rates and message priorities - ideal for separating chassis and infotainment networks in automotive systems.

What debug interface does the R5F10DMGCJFB#56 use?

The R5F10DMGCJFB#56 uses the FINE v3 (Fast In-Circuit Emulator) debug interface, which supports single-wire SWD (Serial Wire Debug) for full-speed programming and real-time tracing. No external debug probe is required beyond a standard SWD adapter, and no dedicated JTAG pins are needed - simplifying PCB layout and reducing pin count overhead.

Is the R5F10DMGCJFB#56 qualified for automotive applications?

The R5F10DMGCJFB#56 is rated for industrial temperature (–40°C to +85°C) and meets AEC-Q200 stress test guidelines for passive components, but it is not officially AEC-Q100 qualified as a complete microcontroller. It is widely used in non-safety-critical automotive body electronics (e.g., BCM, lighting modules); for ASIL-B or higher applications, Renesas recommends the RH850 or RL78/F14 series.
