FAQ

What is the maximum operating frequency and core performance of the R5F56316DGFP#V0?

The R5F56316DGFP#V0 operates at a maximum system clock frequency of 100 MHz and delivers 165 DMIPS of computational performance using the 32-bit RX CPU core. Its single-precision IEEE-754 floating-point unit, 32×32-bit hardware multiplier (1-cycle), and 5-stage pipeline enable deterministic real-time execution critical for industrial control loops and protocol stacks. This performance level is verified under worst-case voltage and temperature conditions (-40 to +85°C, 2.7–3.6 V).

Does the R5F56316DGFP#V0 support Ethernet connectivity, and what physical layer options does it offer?

Yes, the R5F56316DGFP#V0 integrates a full IEEE 802.3/802.3u-compliant Ethernet MAC supporting both MII and RMII interfaces at 10/100 Mbps in full- and half-duplex modes. It includes Magic Packet™ wake-on-LAN detection and flow control per IEEE 802.3x. The device does not include a PHY; external magnetics and a PHY IC (e.g., LAN8720A) are required for physical layer connectivity. RMII mode reduces pin count to 7 signals, simplifying board design.

What analog capabilities does the R5F56316DGFP#V0 provide for sensor interfacing?

The R5F56316DGFP#V0 provides a 21-channel 12-bit successive-approximation ADC with 1 µs conversion time (at 50 MHz PCLK), integrated sample-and-hold, and flexible triggering (software, timer, or external pin). It also includes an 8-channel 10-bit ADC, two 10-bit voltage-output DACs (DA0/DA1), and an on-die temperature sensor accurate to ±1°C. These resources support simultaneous multi-sensor acquisition, closed-loop analog control, and calibration signal generation without external converters.

How does the R5F56316DGFP#V0 support functional safety standards such as IEC 60730?

The R5F56316DGFP#V0 includes multiple hardware features for Class B compliance per IEC 60730: oscillation-stop detection for main/subclocks, independent watchdog timer (IWDT) with dedicated LOCO clock, CRC calculator supporting three polynomials (X⁸+X²+X+1, X¹⁶+X¹⁵+X²+1, X¹⁶+X¹²+X⁵+1), and self-diagnostic routines for the 10-bit ADC. These are documented in Renesas' Functional Safety Manual (R01US0095EJ0100) and validated for use in safety-critical firmware monitoring.

What is the memory configuration of the R5F56316DGFP#V0, and how is it organized for real-time execution?

The R5F56316DGFP#V0 contains 1.5 MB of on-chip flash memory with zero wait-state access at 100 MHz, 192 KB of SRAM with zero wait-state access, and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. Flash is partitioned into user code and boot areas; SRAM is unified for instructions and data. The memory protection unit (MPU) enforces region-based access control, allowing isolation of critical tasks and preventing unintended overwrites - essential for robust real-time multitasking.
