For engineers reviewing the R5F565NEHGFC#V0 datasheet, R5F565NEHGFC#V0 pinout, R5F565NEHGFC#V0 application, or R5F565NEHGFC#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP, 24 × 24 mm, 0.5-mm pitch), confirmed peripheral integration (Ethernet MAC + PHY, dual CAN, 2×12-bit ADC), IEC60730-compliant safety features, and validated alternative part selection for migration or sourcing continuity.

Technical Context

The R5F565NEHGFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a dedicated 120-kHz IWDT clock source, memory protection unit (MPU) supporting eight 16-byte-aligned regions, and Trusted Memory (TM) for code flash read protection.

Its clock system combines external crystal (8–24 MHz), internal HOCO/LOCO oscillators, and PLL for flexible domain partitioning: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for ETHERC/EDMAC/AES/GLCDC/DRW2D, and PCLKB up to 60 MHz for most peripherals including S12AD units and TMR/CMT timers.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F565NEHGFC#V0?

The R5F565NEHGFC#V0 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture and 5-stage pipeline. It delivers 240 DMIPS performance and includes single-precision IEEE-754 floating-point unit, two MAC units, and 32-bit multiplier with one-cycle execution - enabling deterministic real-time control in industrial automation applications where the R5F565NEHGFC#V0 serves as the primary system controller.

Does the R5F565NEHGFC#V0 include an integrated Ethernet PHY?

Yes, the R5F565NEHGFC#V0 integrates a full 10/100 Mbps Ethernet PHY compliant with IEEE 802.3u (MII/RMII), eliminating the need for an external transceiver. This allows direct connection to RJ-45 magnetics and simplifies design of networked gateways and industrial controllers - a key differentiator of the R5F565NEHGFC#V0 within the RX65N family that reduces bill-of-materials cost and PCB complexity.

What package type and pin count does the R5F565NEHGFC#V0 use?

The R5F565NEHGFC#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 × 24 mm body size and 0.5-mm pitch. It provides 136 general-purpose I/O pins with 5-V tolerance on 19 pins, open-drain capability on all I/O, and pull-up resistors - matching the highest I/O count variant in the RX65N Group and enabling maximum peripheral connectivity in the R5F565NEHGFC#V0 implementation.

How does the R5F565NEHGFC#V0 support functional safety standards like IEC60730?

The R5F565NEHGFC#V0 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, frequency measurement circuitry, CRC calculator (CRCA) for memory/data integrity, independent watchdog timer (IWDT) with windowing, self-diagnostic A/D converter test, and register write protection. These capabilities are documented in the R5F565NEHGFC#V0 datasheet (R01DS0276EJ0240) and enable certified safety monitoring without external components.

What are the flash and RAM capacities of the R5F565NEHGFC#V0?

The R5F565NEHGFC#V0 integrates 2 MB of on-chip code flash memory with dual-bank architecture for background programming and safe firmware updates, plus 640 KB of SRAM (256 KB main + 384 KB expansion) with zero-wait-state access at 120 MHz. It also includes 32 KB of reprogrammable data flash (100,000 erase/write cycles) and 8 KB of battery-backed standby RAM - providing robust memory resources for complex R5F565NEHGFC#V0-based applications such as graphical HMIs and protocol gateways.
