FAQ

What is the maximum operating frequency and CPU performance of the R5F56514FDFM#10?

The R5F56514FDFM#10 operates at a maximum system clock frequency of 120 MHz using the RXv2 CPU core, achieving 240 DMIPS performance. Its single-precision IEEE-754 floating-point unit and 23 DSP instructions enable efficient signal processing and real-time control tasks. The R5F56514FDFM#10 sustains zero-wait-state execution on both 640 KB SRAM and code flash (up to 50 MHz or cache-hit conditions), ensuring deterministic timing for industrial applications.

Does the R5F56514FDFM#10 support Ethernet connectivity, and what PHY options are available?

Yes, the R5F56514FDFM#10 integrates a full-featured Ethernet MAC compliant with IEEE 802.3, supporting 10/100 Mbps in full- and half-duplex modes with MII/RMII interface. It does not include an on-die PHY; instead, it connects to external PHY ICs (e.g., DP83848, LAN8720) via dedicated ETXD/ERXD pins. The R5F56514FDFM#10's EDMAC controller offloads packet handling via descriptor-based DMA, reducing CPU overhead to under 15% at line rate.

What security features does the R5F56514FDFM#10 provide for firmware protection and cryptographic operations?

The R5F56514FDFM#10 includes AES-128/192/256 encryption engines, Trusted Secure IP (TSIP) for key management, Trusted Memory (TM) to prevent code flash read-out, Memory Protection Unit (MPU) with eight configurable regions, CRC calculator for 8-/32-bit data, and register write protection. These features collectively support IEC60730 Class B compliance and secure boot, making the R5F56514FDFM#10 suitable for certified industrial and medical devices requiring firmware integrity and data confidentiality.

How many analog-to-digital converter channels does the R5F56514FDFM#10 support, and what resolution options are available?

The R5F56514FDFM#10 integrates two independent 12-bit A/D converter units: S12AD0 with 8 input channels and S12AD1 with 21 input channels - totaling 29 configurable analog inputs. Each unit supports selectable resolution of 8, 10, or 12 bits, with conversion times of 0.42 µs (8-bit), 0.45 µs (10-bit), or 0.48 µs (12-bit) per channel. Both units include self-diagnostic functions, analog input disconnection detection, and digital comparison capabilities - all accessible without CPU intervention via the Event Link Controller.

What display and graphics capabilities are built into the R5F56514FDFM#10?

The R5F56514FDFM#10 features a dedicated Graphic-LCD Controller (GLCDC) supporting up to three overlay planes (background, graphic 1, graphic 2) and multiple pixel formats (32/16 bpp RGB, 8/4/1-bit CLUT). It also includes a 2D Drawing Engine (DRW2D) capable of vector drawing (lines, triangles, circles), bit blitting with rotation/stretching, and texture mapping. These accelerators enable smooth UI rendering on TFT-LCDs up to VGA resolution without external GPU, directly controlled by the R5F56514FDFM#10's CPU via register or display list mode.
