FAQ

What is the maximum operating frequency of the R5F10AMECKFB#15?

The R5F10AMECKFB#15 operates at a maximum frequency of 32 MHz using its on-chip high-speed oscillator or an external crystal. This speed enables real-time execution of LIN protocol stacks, motor control algorithms, and ADC sampling sequences without external acceleration. The R5F10AMECKFB#15 maintains timing accuracy across its full industrial temperature range (−40°C to +85°C) due to integrated frequency calibration.

Does the R5F10AMECKFB#15 include an integrated LIN transceiver?

Yes, the R5F10AMECKFB#15 integrates a fully compliant LIN 2.2A transceiver that meets ISO 17987-4:2016 specifications. It supports both master and slave roles, automatic baud rate detection, and bus wakeup via dominant pulse detection. No external LIN PHY is required, simplifying design and reducing bill-of-materials cost. The R5F10AMECKFB#15's transceiver shares pins TXD0 and RXD0 with the on-chip UART module.

What package type and pin count does the R5F10AMECKFB#15 use?

The R5F10AMECKFB#15 uses a 48-pin QFN package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts and efficient thermal dissipation in automotive modules. Pin compatibility is maintained across all RL78/F13 48-pin variants, including R5F10AMECKFB#15, R5F10ALGCKFB#15, and R5F10AGGCKFB#15.

How much flash memory and RAM does the R5F10AMECKFB#15 provide?

The R5F10AMECKFB#15 includes 64 KB of on-chip flash memory with 100,000 write/erase cycles and 4 KB of SRAM. Flash supports block erase and read-while-write capability for robust firmware updates. SRAM retains data in STOP mode, enabling fast wake-up with preserved context. These memory resources allow implementation of full LIN protocol stacks, sensor fusion algorithms, and diagnostic logging within the R5F10AMECKFB#15 without external memory.

Is the R5F10AMECKFB#15 qualified for automotive applications?

Yes, the R5F10AMECKFB#15 is manufactured under Renesas' automotive quality standards and conforms to AEC-Q100 Grade 2 (−40°C to +105°C). It includes features essential for automotive use: independent watchdog timer (IWDT), low-voltage detection (LVD), flash error correction code (ECC), and LIN bus compliance. While not designated as "High Quality" per Renesas' internal classification, the R5F10AMECKFB#15 is approved for body electronics, lighting, and comfort systems-not safety-critical powertrain or ADAS functions.
