Product details
Overview
R5F10DPFCJFB#12 from Renesas Electronics is a 16-bit RL78/D1A microcontroller in a 100-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated 1-channel CAN interface. It operates at up to 32 MHz, supports 1.8–5.5 V supply, and includes hardware real-time clock, 12-bit ADC (24 channels), and low-power SNOOZE mode for battery-powered industrial control applications.
For engineers reviewing the R5F10DPFCJFB#12 datasheet, R5F10DPFCJFB#12 pinout, R5F10DPFCJFB#12 application, or R5F10DPFCJFB#12 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), on-chip debug support via FINE v3, and compliance with RL78 instruction set architecture for legacy code portability.
Technical Context
The R5F10DPFCJFB#12 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiplication/division and bit manipulation. It integrates a 32-bit programmable watchdog timer, 16-bit multifunction timers (TMH/TML), and a 16-bit real-time clock with calendar function and battery-backed operation.
Its peripheral suite includes a 1-channel CAN controller compliant with ISO 11898-1 (CAN 2.0B), 24-channel 12-bit successive-approximation ADC with internal reference, and 10-bit DAC with output buffer - all accessible via dedicated peripheral I/O registers mapped in the SFR space.

FAQ
What is the maximum operating frequency of the R5F10DPFCJFB#12?
The R5F10DPFCJFB#12 operates at a maximum CPU frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is fully supported across the entire 1.8–5.5 V supply range and ambient temperature range of −40°C to +85°C, with timing guaranteed by Renesas' published AC electrical characteristics.
Does the R5F10DPFCJFB#12 support CAN FD?
No, the R5F10DPFCJFB#12 implements a classical CAN 2.0B controller compliant with ISO 11898-1, supporting data rates up to 1 Mbps but not CAN FD features such as flexible data-rate or extended payload length. For CAN FD, Renesas' RA6T2 or RH850/F1K families are recommended alternatives.
How many ADC channels does the R5F10DPFCJFB#12 have, and what is their resolution?
The R5F10DPFCJFB#12 integrates a 24-channel, 12-bit successive-approximation ADC with hardware averaging, scan mode, and selectable internal reference voltage (1.45 V or VREFH). All channels are accessible via dedicated analog input pins mapped to ports P0–P9, with conversion times as fast as 1.125 μs.
Is the R5F10DPFCJFB#12 pin-compatible with other RL78/D1A 100-pin variants?
Yes, the R5F10DPFCJFB#12 shares identical 100-pin LQFP mechanical footprint and pin assignment with all RL78/D1A 100-pin devices (e.g., R5F10DPE, R5F10DPG, R5F10DPJ), including power, reset, debug, and peripheral I/O pin locations - enabling PCB reuse across memory and feature variants within the same pin-count group.
What debug interface does the R5F10DPFCJFB#12 use, and does it require external hardware?
The R5F10DPFCJFB#12 uses the FINE v3 on-chip debug interface, which requires only two dedicated pins (F_IN and F_OUT) and no external debug probe for basic programming and breakpoint debugging. Full trace and real-time analysis are supported via compatible Renesas E2 or E2 Lite debuggers connected through the same interface.
