Overview

R5F10DGCLFB#V0 from Renesas Electronics is a 16-bit RL78/D1A microcontroller with integrated CAN 2.0B controller, 128 KB flash, 8 KB RAM, and 48-pin LQFP package. It operates at up to 32 MHz, supports 1.8–5.5 V supply, and targets automotive body electronics requiring CAN communication, low-power operation, and functional safety support.

For engineers reviewing the R5F10DGCLFB#V0 datasheet, R5F10DGCLFB#V0 pinout, R5F10DGCLFB#V0 application, or R5F10DGCLFB#V0 equivalent, key selection criteria include CAN channel count (1 ch), flash endurance (100k write/erase cycles), on-chip debug interface (on-chip debug), operating temperature range (−40°C to +105°C), and AEC-Q100 Grade 2 qualification status.

Technical Context

The R5F10DGCLFB#V0 implements the RL78 CPU core with 3-stage pipeline, 16-bit ALU, and CISC instruction set optimized for ultra-low-power embedded control. It integrates a 1-channel CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames, programmable bit timing, and automatic retransmission.

On-chip peripherals include 12-bit ADC (24 channels), 8-bit D/A converter, 16-bit timer arrays (TAU), real-time clock (RTC), LIN master interface, and hardware multiplier/divider. Power management features include HALT, STOP, and SNOOZE modes with wake-up via CAN interrupt or external pin.

FAQ

What is the maximum operating frequency of the R5F10DGCLFB#V0?

The R5F10DGCLFB#V0 operates at a maximum CPU frequency of 32 MHz, achieved using an on-chip high-speed oscillator (HOCO) or external crystal. This frequency is fully supported across the full −40°C to +105°C temperature range and 1.8–5.5 V supply voltage, enabling deterministic real-time control in automotive environments. The R5F10DGCLFB#V0 maintains timing accuracy without external PLL circuitry.

Does the R5F10DGCLFB#V0 include an integrated CAN transceiver?

No, the R5F10DGCLFB#V0 integrates only the CAN protocol controller (MAC layer), not the physical transceiver (PHY layer). External CAN transceivers such as the R7F0C004 or industry-standard parts like TJA1042T/3 must be used to interface with the CAN bus. The R5F10DGCLFB#V0 provides dedicated CAN_TX and CAN_RX pins (P00/P01) compatible with standard ISO 11898-2 transceivers.

What debug interface does the R5F10DGCLFB#V0 support?

The R5F10DGCLFB#V0 supports Renesas' on-chip debug (OCD) interface via Serial Wire Debug (SWD) using the RESET pin and one additional dedicated debug pin. No external JTAG emulator is required-debugging, flash programming, and real-time variable monitoring are enabled directly through the SWD port, reducing development tooling cost and board space.

Is the R5F10DGCLFB#V0 qualified for automotive use?

Yes, the R5F10DGCLFB#V0 is AEC-Q100 qualified to Grade 2 (−40°C to +105°C), with full test reports covering HTOL, ESD, and EMC per automotive requirements. It is designated for "Standard" quality grade applications per Renesas documentation, and its qualification makes it suitable for under-hood and cabin body electronics-not safety-critical powertrain or ADAS systems.

How much user-accessible flash memory does the R5F10DGCLFB#V0 provide?

The R5F10DGCLFB#V0 provides 128 KB of on-chip flash memory, all user-programmable and organized into 1 KB sectors. Up to 4 KB can be reserved for bootloader code, leaving 124 KB for application firmware. Flash supports 100,000 write/erase cycles and data retention exceeding 20 years at +85°C, verified per JEDEC JESD22-A117.
