FAQ
What communication protocols does the R5F10BBFLNA#G5 natively support?
The R5F10BBFLNA#G5 integrates a hardware CAN 2.0B controller and a dedicated LIN 2.2A controller. It does not include USB, Ethernet, SPI master-only peripherals, or I²C slave functionality. CAN and LIN operate independently with separate register sets and interrupt vectors, enabling concurrent bus activity without CPU arbitration overhead. The R5F10BBFLNA#G5 requires an external CAN transceiver (e.g., TJA1042) and LIN transceiver (e.g., TLE7259) for physical layer compliance.
Does the R5F10BBFLNA#G5 include on-chip EEPROM or data flash memory?
Yes, the R5F10BBFLNA#G5 includes 2 KB of on-chip data flash memory that functions as EEPROM-equivalent storage. This memory supports 100,000 write/erase cycles and retains data for 20 years at 85°C. It is accessed via dedicated FLM (Flash Memory) control registers and can be programmed during normal operation without halting the CPU-enabling runtime parameter updates in automotive calibration or industrial configuration applications using the R5F10BBFLNA#G5.
What is the maximum operating frequency and voltage range for the R5F10BBFLNA#G5?
The R5F10BBFLNA#G5 operates at a maximum CPU clock frequency of 24 MHz across its full supply voltage range of 1.6 V to 5.5 V. At 5.5 V, it achieves 24 MHz with no wait states; at 1.6 V, the maximum frequency is reduced to 8 MHz per Renesas' electrical specifications. The device includes an on-chip voltage regulator and programmable low-voltage detection (LVD) with 12 threshold levels to prevent operation outside safe margins-critical for battery-powered or variable-supply automotive applications using the R5F10BBFLNA#G5.
Can the R5F10BBFLNA#G5 enter ultra-low-power modes, and what is the typical current draw?
Yes, the R5F10BBFLNA#G5 supports multiple low-power modes including HALT, STOP, and SNOOZE. In STOP mode with RTC active and wake-up enabled on CAN or LIN activity, typical current consumption is 0.25 µA at 25°C. The R5F10BBFLNA#G5 retains all RAM contents and register states in STOP mode, and resumes execution within 4 µs of wake-up-making it suitable for always-on vehicle modules like door controllers or tire pressure monitors where rapid response and minimal quiescent current are essential.
Is the R5F10BBFLNA#G5 qualified for automotive applications, and what temperature grade does it carry?
The R5F10BBFLNA#G5 is rated for industrial temperature range (−40°C to +105°C) and classified by Renesas as a "Standard" quality grade device. While widely used in automotive body electronics (e.g., door modules, seat controls), it is not AEC-Q100 qualified. For applications requiring formal automotive qualification, Renesas offers AEC-Q100–qualified variants in the RL78/F13 family (e.g., R5F10BBFLNA#G5's pin-compatible AEC-Q100 version is designated separately). Always verify qualification status in the official R5F10BBFLNA#G5 datasheet before deployment in safety-critical automotive systems.
