FAQ
What is the maximum operating frequency of the R5F10BGCLNA#G5?
The R5F10BGCLNA#G5 operates at a maximum CPU frequency of 32 MHz using the high-speed on-chip oscillator (HOCO) or external crystal. At this speed, it delivers 1.25 DMIPS/MHz performance, enabling real-time execution of CAN protocol stack, LIN scheduling, and sensor processing within tight timing budgets. The device supports dynamic clock switching between HOCO, sub-oscillator, and external sources without software intervention.
Does the R5F10BGCLNA#G5 require an external CAN transceiver?
No, the R5F10BGCLNA#G5 includes a fully compliant CAN 2.0B controller with message RAM and hardware FIFO, but it does not integrate the physical layer (PHY). An external CAN transceiver (e.g., TJA1042 or SN65HVD230) is required for bus-level signaling. However, its P10/P11 pins are dedicated CAN TX/RX logic-level outputs, simplifying interface design and reducing routing complexity compared to discrete controller+transceiver solutions.
How many LIN channels does the R5F10BGCLNA#G5 support?
The R5F10BGCLNA#G5 supports one LIN channel via its integrated LIN physical layer on P40 (LIN_TX) and P41 (LIN_RX). It operates in both master and slave modes with auto-baud detection and supports LIN 2.2A and ISO 17987-4 standards. This single-channel implementation is sufficient for typical sensor/actuator nodes, and the hardware handles break detection, sync field generation, and checksum calculation without CPU overhead.
What is the endurance rating of the data flash in the R5F10BGCLNA#G5?
The R5F10BGCLNA#G5 includes 2 KB of on-chip data flash rated for 100,000 write/erase cycles and 20-year data retention at 85°C. This memory region is electrically isolated from main program flash and supports byte-level writes and sector erases, making it ideal for storing calibration coefficients, device IDs, or runtime configuration parameters that must survive power loss and field updates. The R5F10BGCLNA#G5 firmware can manage wear leveling via Renesas-provided driver libraries.
Is the R5F10BGCLNA#G5 qualified for automotive applications?
Yes, the R5F10BGCLNA#G5 is manufactured under Renesas' "High Quality" grade and conforms to AEC-Q100 Grade 2 (−40°C to +105°C ambient) qualification. It is designed for automotive body electronics including door modules, lighting controllers, and HVAC actuators. Its integrated CAN/LIN, low-power modes, and robust ESD immunity (±4 kV HBM) meet functional safety requirements for ASIL-A systems, and Renesas provides FIT rate data and failure-in-time analysis for the R5F10BGCLNA#G5 in its reliability reports.
