It supports low-power operation (140 μA/MHz in active mode, 0.52 μA in deep standby), hardware real-time clock, and 12-bit ADC with 24 channels - deployed in automotive body control modules requiring functional safety-aware firmware execution.
For engineers reviewing the R5F10DSLLFB#X6G datasheet, R5F10DSLLFB#X6G pinout, R5F10DSLLFB#X6G application, or R5F10DSLLFB#X6G equivalent, this page delivers verified electrical specs, validated pin functions for 128-pin LQFP, confirmed CAN dual-channel timing behavior, and direct alternative options for ECU redesigns where footprint, interrupt latency, and flash endurance are critical selection criteria.
Technical Context
The R5F10DSLLFB#X6G implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiply/divide and bit manipulation. It integrates dual CAN controllers compliant with ISO 11898-1:2015, each with 32 message objects and programmable acceptance filtering.
On-chip peripherals include a 12-bit ADC with sample-and-hold and window comparator, 16-bit timer arrays (TMR0–TMR3) with dead-time insertion, and a hardware CRC calculator. Power management includes five low-power modes with wake-up via external interrupt, RTC alarm, or peripheral event trigger.

FAQ
What is the maximum operating frequency of the R5F10DSLLFB#X6G?
The R5F10DSLLFB#X6G operates at a maximum CPU frequency of 32 MHz, achieved using an on-chip high-speed oscillator or external crystal up to 20 MHz with PLL multiplication. This frequency enables sub-microsecond interrupt response times and supports real-time control loops in automotive body electronics applications where the R5F10DSLLFB#X6G is commonly deployed.
Does the R5F10DSLLFB#X6G support CAN FD?
No, the R5F10DSLLFB#X6G supports only Classical CAN 2.0B (up to 1 Mbps), not CAN FD. Its dual CAN controllers comply with ISO 11898-1:2015 for standard frame format and extended frame format only. For CAN FD requirements, designers must consider newer RL78/G23 or RA-family devices - the R5F10DSLLFB#X6G is intended for established CAN 2.0B network architectures in body control systems.
What package type and pin count does the R5F10DSLLFB#X6G use?
The R5F10DSLLFB#X6G uses a 128-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. This package supports full pin access to both CAN channels, all 24 ADC inputs, and dedicated LIN-compatible GPIO - matching the physical layout requirements of automotive ECUs where the R5F10DSLLFB#X6G serves as primary controller.
Is the R5F10DSLLFB#X6G qualified for automotive applications?
Yes, the R5F10DSLLFB#X6G is AEC-Q100 Grade 2 qualified (−40°C to +105°C) and designated by Renesas as a "High Quality" grade product for transportation equipment. It meets automotive reliability standards for vibration, thermal cycling, and ESD immunity - making it suitable for under-hood and cabin-mounted ECUs where the R5F10DSLLFB#X6G is specified for long-term deployment.
Does the R5F10DSLLFB#X6G include hardware security features?
The R5F10DSLLFB#X6G includes read-out protection (ROM code protection), secure boot via flash lock bits, and memory protection unit (MPU) for peripheral access control - but no cryptographic accelerators or TRNG. These features support basic firmware IP protection and tamper-resistant boot in entry-level automotive applications where the R5F10DSLLFB#X6G is used without requiring full ASIL-D security stacks.
