FAQ
What is the maximum operating frequency of the R5F5631JDDFP#V0?
The R5F5631JDDFP#V0 operates at a maximum system clock frequency of 100 MHz, delivering 165 DMIPS performance. This frequency is sustained across its full operating temperature range (–40°C to +85°C) and supply voltage (2.7–3.6 V), with zero-wait-state access to both 1.5 MB flash and 256 KB SRAM - enabling hard real-time deterministic execution critical for industrial control loops.
Does the R5F5631JDDFP#V0 include an Ethernet MAC controller?
No, the R5F5631JDDFP#V0 belongs to the RX631 Group and does not integrate an Ethernet MAC controller. That feature is exclusive to the RX63N Group. The R5F5631JDDFP#V0 instead emphasizes USB 2.0 function controller, CAN, multiple SCI/RSPI/I²C interfaces, and robust analog subsystems - making it ideal for non-networked embedded controllers where USB connectivity and analog precision are prioritized over Ethernet.
What package type is used for the R5F5631JDDFP#V0?
The R5F5631JDDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 10 × 10 mm body size and 0.5 mm pin pitch. This RoHS-compliant, surface-mount package supports standard reflow profiles and provides 78 general-purpose I/O pins, including 17 with 5-V tolerance - facilitating direct interfacing with legacy industrial sensors and logic families without level-shifting circuitry.
How many A/D converter channels does the R5F5631JDDFP#V0 support?
The R5F5631JDDFP#V0 integrates two independent A/D converters: a 21-channel 12-bit S12AD unit and an 8-channel 10-bit AD unit. Both support sample-and-hold, software/external/timer-triggered conversion, and operate with 1.0 μs conversion time at 50 MHz peripheral clock - enabling simultaneous high-resolution acquisition of multiple analog signals such as current, voltage, temperature, and pressure in industrial monitoring applications.
Is the R5F5631JDDFP#V0 suitable for IEC 60730 Class B compliance?
Yes, the R5F5631JDDFP#V0 includes multiple hardware features supporting IEC 60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculator, independent watchdog timer (IWDT) with dedicated LOCO clock, self-diagnostic function for the 10-bit A/D converter, and frequency measurement capability via MTU/TPU modules - collectively enabling robust runtime safety checks required for household and industrial appliances.
