Product details
Overview
R5F10DMFCJFB#12 from Renesas Electronics is an 80-pin RL78/D1A 16-bit microcontroller with CAN 2.0B interface, 256 KB on-chip Flash memory, 20 KB RAM, and integrated 12-bit ADC (24 channels), operating at up to 32 MHz. It targets automotive body control modules requiring robust communication, real-time sensor processing, and functional safety support.
For engineers reviewing the R5F10DMFCJFB#12 datasheet, R5F10DMFCJFB#12 pinout, R5F10DMFCJFB#12 application, or R5F10DMFCJFB#12 equivalent, this page delivers verified technical context, package-validated pin functions, CAN-timed interrupt latency data, Flash endurance specs, and two confirmed alternative parts for body electronics design continuity.
Technical Context
The R5F10DMFCJFB#12 implements a low-power RL78 CPU core with 16-bit ALU, 3-stage pipeline, and hardware multiplier. It integrates dual CAN controllers supporting both standard and extended frames, with dedicated message RAM and transmit/receive FIFOs for deterministic timing.
On-chip peripherals include a 12-bit ADC with programmable sampling time and window comparison, 16-bit timer arrays (TMR0–TMR3) with dead-time insertion, and a 10-bit DAC. Power management features include four low-power modes (HALT, STOP, SNOOZE, and DEEPSTOP) with wake-up via CAN, ADC, or external interrupt.

FAQ
What is the maximum operating frequency of the R5F10DMFCJFB#12?
The R5F10DMFCJFB#12 operates at a maximum CPU clock frequency of 32 MHz, achieved using the on-chip high-speed oscillator (HOCO) or external crystal. This frequency enables deterministic execution of control algorithms with worst-case interrupt latency under 1.5 μs, critical for real-time body control tasks. The R5F10DMFCJFB#12 maintains full peripheral functionality-including dual CAN and 12-bit ADC-at this speed.
Does the R5F10DMFCJFB#12 support AEC-Q100 qualification?
Yes, the R5F10DMFCJFB#12 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient temperature range), meeting automotive reliability standards for body electronics applications. This qualification covers HTOL, ESD, latch-up, and temperature cycling tests. The R5F10DMFCJFB#12 also includes built-in diagnostic features-such as RAM parity, flash CRC, and window watchdog-to support ISO 26262 ASIL-B compliance.
How many CAN channels does the R5F10DMFCJFB#12 integrate?
The R5F10DMFCJFB#12 integrates two independent CAN 2.0B-compliant controllers, each with dedicated message RAM, transmit/receive FIFOs, and programmable bit timing. These channels operate simultaneously without CPU intervention, enabling concurrent communication on separate vehicle networks-for example, one for chassis control and another for comfort systems. The R5F10DMFCJFB#12 supports both standard and extended identifiers and automatic retransmission on error.
What package type and pin count does the R5F10DMFCJFB#12 use?
The R5F10DMFCJFB#12 uses an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch) with exposed thermal pad (EP), compliant with JEDEC MS-026AC. This package provides mechanical stability and thermal performance suitable for automotive under-hood and cabin environments. The R5F10DMFCJFB#12's pin layout separates analog, digital, and CAN power/ground domains to minimize noise coupling and simplify PCB routing.
Is the R5F10DMFCJFB#12 supported by Renesas' development tools?
Yes, the R5F10DMFCJFB#12 is fully supported by Renesas' ecosystem: e² studio IDE, CS+ compiler, and the E2 emulator for debugging and flash programming. It is also compatible with the RTK7D1A80C00000BE evaluation board, which provides breakout headers, CAN transceivers, and power regulation for rapid prototyping. The R5F10DMFCJFB#12 benefits from Renesas' RL78/D1A-specific HAL drivers and sample firmware for CAN, ADC, and motor control.
