FAQ

What is the maximum operating frequency and corresponding power consumption of the R5F11BBEGFP#10?

The R5F11BBEGFP#10 operates at up to 32 MHz using the high-speed on-chip oscillator. At this frequency, its typical active current is 66 μA per MHz under standard conditions (VDD = 3.3 V, TA = 25°C), resulting in ~2.1 mA total active current. This value scales linearly with clock speed, enabling precise power budgeting for battery-operated devices.

Does the R5F11BBEGFP#10 support LIN bus communication natively, and how is it implemented?

Yes, the R5F11BBEGFP#10 supports LIN bus communication through UART0 with dedicated LINSEL pin functionality. The hardware automatically detects sync-break fields and handles LIN protocol framing, eliminating software overhead. This implementation meets LIN 2.2A specification requirements and is validated for use in automotive door modules and seat controllers where R5F11BBEGFP#10 serves as the primary LIN master.

How many analog-to-digital converter channels does the R5F11BBEGFP#10 provide, and what are their key specifications?

The R5F11BBEGFP#10 integrates an 8/10-bit resolution ADC with 13 configurable analog input channels (ANI0–ANI7, ANI16–ANI20). It supports internal 1.45 V reference voltage, on-chip temperature sensor, and AVREFP/AVREFM differential reference inputs. Conversion time is 1.2 μs per sample at 10-bit resolution, and the ADC operates across the full 1.6–5.5 V VDD range, making R5F11BBEGFP#10 suitable for wide-input-range sensor interfaces.

What packaging and temperature grade does the R5F11BBEGFP#10 have, and how does that affect its use cases?

The R5F11BBEGFP#10 uses a 32-pin plastic LQFP package (7 × 7 mm, 0.8 mm pitch) rated for industrial temperature range (−40°C to +105°C), indicated by the "G" suffix. This allows deployment in harsh environments such as factory automation controllers, automotive engine compartments, and outdoor metering equipment where extended thermal stability is mandatory - unlike consumer-grade "A" variants limited to +85°C.

Can the R5F11BBEGFP#10 perform background data flash writes while executing application code from main flash memory?

Yes, the R5F11BBEGFP#10 supports background operation (BGO) for its 4 KB data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten, enabling seamless logging, parameter storage, or firmware update staging without halting real-time tasks. This capability is fully implemented in R5F11BBEGFP#10's hardware and requires no external memory or DMA arbitration logic.
