FAQ

What is the maximum operating frequency of the R5F10BLGLFB#X5?

The R5F10BLGLFB#X5 operates at up to 24 MHz using its internal high-speed oscillator or an external crystal. This frequency is fully supported across its entire specified temperature and voltage range (−40 °C to +85 °C, 1.8–5.5 V), enabling consistent real-time execution for LIN/CAN protocol timing and ADC sampling without derating.

Does the R5F10BLGLFB#X5 include a hardware LIN transceiver?

No, the R5F10BLGLFB#X5 includes a LIN protocol controller but not a physical-layer transceiver. It provides LINRX and LINTX pins that require connection to an external LIN transceiver (e.g., TLE7259-3GE) to meet ISO 17987-2 physical layer requirements. The on-die LIN engine handles all protocol-level tasks including sync-break detection and checksum generation.

Is the R5F10BLGLFB#X5 AEC-Q100 qualified?

Yes, the R5F10BLGLFB#X5 is AEC-Q100 qualified to Grade 2 (−40 °C to +85 °C), as documented in Renesas' official qualification reports. This qualification covers stress testing for temperature cycling, humidity bias, ESD, and latch-up - confirming suitability for automotive interior applications such as door modules and seat controls.

How much flash memory does the R5F10BLGLFB#X5 have, and is it write-protected?

The R5F10BLGLFB#X5 contains 64 KB of on-chip flash memory with 100 k-cycle endurance and 20-year data retention. Flash protection is implemented via lock bits configurable through the on-chip debug interface or ROM bootloader - enabling sector-level write/read protection to prevent accidental or malicious firmware modification.

Can the R5F10BLGLFB#X5 operate from a 3.3 V supply?

Yes, the R5F10BLGLFB#X5 supports 3.3 V operation across its full temperature range. Its 1.8–5.5 V supply range allows direct interfacing with 3.3 V logic peripherals without level shifters, and internal voltage regulators ensure stable core and analog domain operation even with ±5% supply variation typical in automotive 3.3 V rails.
