It features a 32 MHz max CPU clock, 12-bit ADC (24 channels), 16-bit timer arrays (TMR0–TMR3), and low-power SNOOZE mode for battery-powered industrial sensing and control applications.
For engineers reviewing the R5F10DMJCLFB#12 datasheet, R5F10DMJCLFB#12 pinout, R5F10DMJCLFB#12 application, or R5F10DMJCLFB#12 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), on-chip debug interface (FINE), and compliance with AEC-Q100 Grade 2 for extended temperature operation (−40°C to +105°C).
Technical Context
The R5F10DMJCLFB#12 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions and 3-stage pipeline execution. It integrates dual CAN controllers (CAN0/CAN1) with message objects (32 × 16-bit FIFO), programmable bit timing, and loopback self-test mode.
On-chip peripherals include a 12-bit successive-approximation ADC with sample-and-hold, 16-bit real-time clock (RTC) with calendar function, and hardware multiplier/divider. Power management includes five low-power modes (HALT, STOP, SNOOZE, DEEP STOP, and ULTRA DEEP STOP) with wake-up via CAN interrupt or external pin.

FAQ
What is the maximum operating frequency of the R5F10DMJCLFB#12?
The R5F10DMJCLFB#12 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal/resonator. Its 3-stage pipeline architecture enables efficient instruction execution at this rate, with typical current consumption of 3.2 mA at 32 MHz and 3.3 V supply. The R5F10DMJCLFB#12 also supports sub-1 MHz operation in low-power modes for extended battery life.
Does the R5F10DMJCLFB#12 support CAN FD?
No, the R5F10DMJCLFB#12 implements CAN 2.0B protocol only, not CAN FD. It provides two fully independent CAN 2.0B controllers (CAN0 and CAN1), each supporting standard and extended frame formats, programmable bit timing, and 32 message objects with maskable acceptance filtering. For CAN FD requirements, consider Renesas' RA6T2 or third-party alternatives such as NXP's S32K144.
What debug interface does the R5F10DMJCLFB#12 use?
The R5F10DMJCLFB#12 uses Renesas' FINE (Fast In-circuit Non-intrusive Emulator) single-wire debug interface. This allows full real-time debugging-including breakpoints, watchpoints, and memory inspection-without halting peripheral operation. FINE requires only one dedicated pin (typically P140) and is supported by Renesas CS+ and e2 studio IDEs. No external JTAG adapter is needed for basic development.
Is the R5F10DMJCLFB#12 qualified for automotive applications?
Yes, the R5F10DMJCLFB#12 is qualified per AEC-Q100 Grade 2 (−40°C to +105°C), making it suitable for under-hood and cabin automotive applications such as body control modules, lighting controllers, and HVAC actuators. It meets stringent reliability, ESD, and thermal cycling requirements defined in the AEC standard, and its dual-CAN capability supports distributed vehicle networks compliant with ISO 11898-1.
How much EEPROM emulation is available on the R5F10DMJCLFB#12?
The R5F10DMJCLFB#12 does not include physical EEPROM but supports EEPROM emulation in its on-chip flash memory using Renesas' Flash Self-Programming (FSP) library. Up to 4 KB of flash can be allocated for emulated EEPROM with wear-leveling, supporting 100 k write/erase cycles and data retention exceeding 10 years at 85°C. This feature is implemented in firmware and requires no external components.
