FAQ

What is the maximum operating frequency of the R5F10PMJLFB#V0?

The R5F10PMJLFB#V0 operates at a maximum CPU frequency of 32 MHz, achieved using the on-chip high-speed oscillator (HOCO) or external crystal/resonator up to 20 MHz with PLL multiplication. This frequency is fully supported across the entire −40°C to +105°C temperature range and 1.8–5.5 V supply voltage window, ensuring deterministic real-time performance in automotive environments.

Does the R5F10PMJLFB#V0 support LIN 2.2A protocol natively?

Yes, the R5F10PMJLFB#V0 supports LIN 2.2A natively through its Serial Array Unit (SAU0), which implements hardware-level break detection, sync field handling, identifier filtering, checksum calculation (classic and enhanced), and automatic response transmission. No firmware intervention is required for basic frame exchange, and timing meets LIN specification tolerances even under worst-case voltage and temperature conditions.

What is the data retention capability of the on-chip data flash in R5F10PMJLFB#V0?

The R5F10PMJLFB#V0 includes 8 KB of on-chip data flash rated for 100,000 write/erase cycles and 20 years of data retention at +85°C. This allows robust EEPROM emulation for calibration data, user preferences, or fault logs without external non-volatile memory - verified per JEDEC JESD22-A117 standard and included in Renesas' AEC-Q100 stress test reports.

Is the R5F10PMJLFB#V0 qualified to AEC-Q100 standards?

Yes, the R5F10PMJLFB#V0 is AEC-Q100 qualified to Grade 2 (−40°C to +105°C), covering stress tests including HTOL, TC, UHAST, ESD-HBM/MM, and latch-up. Certification documentation is available from Renesas under NDA, and the device carries the "Automotive" designation in official part numbering - confirming suitability for passenger compartment and under-hood automotive applications.

How many ADC channels does the R5F10PMJLFB#V0 support, and what is their resolution?

The R5F10PMJLFB#V0 supports 24 analog input channels with a 10-bit successive approximation ADC. It achieves ±1 LSB integral nonlinearity (INL) and 1.0 μs conversion time at maximum sampling rate. Channels are multiplexed across ports P0–P5 and P10, with hardware trigger support from TAU timers and external events - enabling precise synchronous sampling for motor current or battery voltage monitoring.
