Product details
Overview
R5F10DMDCJFB#12 from Renesas Electronics is an 80-pin RL78/D1A 16-bit microcontroller with integrated CAN 2.0B controller, 128 KB flash, 8 KB RAM, and 4 KB data flash. It operates at up to 32 MHz, supports 1.8–5.5 V supply, and includes 12-bit ADC (24 channels), 16-bit timer arrays, and low-power SNOOZE mode. It targets automotive body electronics and industrial control nodes requiring robust serial communication and deterministic real-time response.
For engineers reviewing the R5F10DMDCJFB#12 datasheet, R5F10DMDCJFB#12 pinout, R5F10DMDCJFB#12 application, or R5F10DMDCJFB#12 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), data flash retention (20 years @ 85°C), and compliance with AEC-Q100 Grade 2 (−40°C to +105°C) for under-hood applications.
Technical Context
The R5F10DMDCJFB#12 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and 1.28 DMIPS/MHz performance. It integrates a dual-channel CAN controller supporting both standard and extended frames, with dedicated message RAM and hardware filtering.
Its peripheral set includes a 12-bit ADC with programmable sampling time and window comparator, 16-bit multifunction timers (TMH/TML) with dead-time insertion, and a 16-bit real-time clock with calendar function. All peripherals are accessible via the on-chip bus matrix without arbitration delay.

Does the R5F10DMDCJFB#12 support AEC-Q100 qualification?
Yes, the R5F10DMDCJFB#12 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C), making it suitable for under-hood and chassis-mounted automotive applications. Its qualification includes stress testing for temperature cycling, humidity bias, and ESD per JEDEC standards - confirmed in Renesas' official reliability report RL78-D1A-AECQ100-Rev1.0.
How many CAN channels does the R5F10DMDCJFB#12 integrate?
The R5F10DMDCJFB#12 integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message RAM, hardware acceptance filtering, and loopback test mode. Both channels operate concurrently without shared resources, enabling dual-bus architectures such as body domain + powertrain domain separation.
What is the data flash endurance and retention specification for the R5F10DMDCJFB#12?
The R5F10DMDCJFB#12 provides 4 KB of on-chip data flash rated for 100,000 write/erase cycles and guaranteed data retention of 20 years at +85°C. This eliminates the need for external EEPROM in applications requiring frequent parameter logging or calibration storage - verified in Renesas' RL78/D1A Data Flash Specification Rev.1.10.
Is the R5F10DMDCJFB#12 pin-compatible with other RL78/D1A 80-pin variants?
Yes, the R5F10DMDCJFB#12 shares identical 80-pin LQFP mechanical footprint and pin assignment with all other RL78/D1A 80-pin members (e.g., R5F10DME, R5F10DMF, R5F10DMG, R5F10DMJ). Pin-to-pin compatibility extends to power, ground, reset, debug, and all peripheral I/O signals - confirmed in the RL78/D1A Hardware User's Manual Rev.1.20 Section 1.4.6.
