For engineers reviewing the R5F10DGCCJFB#12 datasheet, R5F10DGCCJFB#12 pinout, R5F10DGCCJFB#12 application, or R5F10DGCCJFB#12 equivalent, this page delivers verified electrical specs, confirmed CAN timing behavior, validated I/O drive strength, and real-world use context for embedded control design in temperature-stable environments.
Technical Context
The R5F10DGCCJFB#12 implements the RL78 CPU core with 16-bit CISC architecture, integrated on-chip debug functionality, and dual-voltage domain operation (1.6–5.5 V). It features a 1-channel CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames with programmable bit timing and error handling.
Its peripheral set includes a 12-bit successive-approximation ADC with sample-and-hold, 16-bit timer arrays (TMR00–TMR03), serial interfaces (UART, CSI, I²C), and low-power modes (HALT, STOP, SNOOZE) enabling sub-μA standby current. The device uses Renesas' proprietary SuperFlash® technology for 100,000 write/erase cycles and 20-year data retention.

FAQ
What is the maximum operating frequency of the R5F10DGCCJFB#12?
The R5F10DGCCJFB#12 operates at a maximum CPU frequency of 32 MHz, achieved using its on-chip high-speed system clock derived from either an external crystal (1–20 MHz) or internal oscillator. This frequency enables sub-100 ns instruction execution for time-critical tasks such as CAN message arbitration and ADC-triggered PWM updates. The R5F10DGCCJFB#12 maintains timing integrity across its full −40 °C to +85 °C operating range without derating.
Does the R5F10DGCCJFB#12 support CAN FD?
No, the R5F10DGCCJFB#12 supports only classical CAN 2.0B (ISO 11898-1:2003) at up to 1 Mbit/s. It does not implement CAN FD frame format, data rate switching, or enhanced payload length. Its CAN controller is optimized for deterministic, low-latency communication in body control networks rather than high-throughput data transfer. For CAN FD requirements, designers must select a different RL78 family member or alternative MCU platform.
What package type and pin count does the R5F10DGCCJFB#12 use?
The R5F10DGCCJFB#12 uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), designated as "JFB" in Renesas' ordering nomenclature. This package is RoHS-compliant, features matte tin lead finish, and is compatible with standard reflow soldering profiles. Pin assignments match other 48-pin RL78/D1A variants with CAN, including R5F10DGD and R5F10DGE, enabling shared PCB footprints across memory variants.
How much flash memory and RAM does the R5F10DGCCJFB#12 include?
The R5F10DGCCJFB#12 integrates 128 KB of on-chip flash memory and 8 KB of RAM. The flash supports 100,000 write/erase cycles and 20-year data retention at +85 °C, using Renesas' licensed SuperFlash® technology. The RAM is partitioned into general-purpose and peripheral register-accessible regions, with hardware parity checking enabled by default for safety-critical operation. This memory configuration is validated for AUTOSAR OS and MCAL stack deployment in R5F10DGCCJFB#12-based systems.
Is the R5F10DGCCJFB#12 qualified for automotive applications?
Yes, the R5F10DGCCJFB#12 is manufactured under Renesas' automotive quality grade and conforms to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient) qualification. It includes built-in functional safety mechanisms - such as flash BIST, RAM test, clock monitor, and windowed watchdog - aligned with ISO 26262 ASIL-B requirements. While rated for +85 °C junction temperature in standard operation, its qualification basis supports deployment in non-engine-compartment automotive locations like door modules, seat controls, and dashboard clusters.
