FAQ

What is the maximum operating frequency and CPU performance of the R5F563NBDDFB#V0?

The R5F563NBDDFB#V0 operates at a maximum system clock frequency of 100 MHz. Its RXv1 32-bit CPU core delivers 165 DMIPS of performance at this speed, supported by a 5-stage pipeline, single-precision IEEE-754 FPU, and ultra-compact variable-length instruction set. This enables deterministic execution of real-time control algorithms and protocol stacks on the R5F563NBDDFB#V0.

Does the R5F563NBDDFB#V0 include an Ethernet controller, and what standards does it support?

Yes, the R5F563NBDDFB#V0 includes a fully integrated IEEE 802.3-compliant Ethernet MAC supporting both 10 Mbps and 100 Mbps operation in full- and half-duplex modes. It implements MII and RMII physical layer interfaces, Magic Packet™ wake-on-LAN detection, and IEEE 802.3x flow control-making the R5F563NBDDFB#V0 suitable for industrial Ethernet edge nodes.

What are the memory resources available on the R5F563NBDDFB#V0?

The R5F563NBDDFB#V0 integrates 1 MB of on-chip flash memory with zero wait-state access at 100 MHz, 128 KB of high-speed SRAM, and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. All memory blocks support background operation, allowing code execution during flash programming-a key capability for field-upgradable firmware on the R5F563NBDDFB#V0.

How many analog-to-digital converter channels does the R5F563NBDDFB#V0 support, and what are their resolutions?

The R5F563NBDDFB#V0 features 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 when PCLK is 50 MHz. These resources enable high-fidelity sensor acquisition in motor control and energy metering applications using the R5F563NBDDFB#V0.

Is the R5F563NBDDFB#V0 qualified for industrial temperature operation, and what is its operating voltage range?

Yes, the R5F563NBDDFB#V0 is rated for industrial temperature operation from −40°C to +85°C (D version). It operates from a single 2.7 V to 3.6 V supply across VCC, AVCC0, VREFH, and VCC_USB pins, with VBATT supporting 2.0 V to 3.6 V for RTC backup. This wide voltage tolerance ensures robust operation in fluctuating industrial power environments for the R5F563NBDDFB#V0.
