FAQ

What is the maximum operating frequency of the R5F72395ADFP#V0?

The R5F72395ADFP#V0 operates at a maximum frequency of 120 MHz. This clock speed is achieved using the on-chip PLL with external crystal input (typically 8 MHz or 12 MHz), and it enables sub-10 µs interrupt response times essential for real-time motor control loops. The R5F72395ADFP#V0 maintains this frequency across its specified industrial temperature range (−40°C to +85°C) with appropriate decoupling and thermal design.

Does the R5F72395ADFP#V0 include a hardware floating-point unit?

Yes, the R5F72395ADFP#V0 integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) within its SH-2A CPU core. This FPU accelerates trigonometric, exponential, and division operations required in field-oriented motor control algorithms. Unlike software-emulated FP, the hardware FPU in the R5F72395ADFP#V0 reduces computation latency by over 60%, directly improving control loop stability and dynamic response.

How many CAN interfaces does the R5F72395ADFP#V0 support?

The R5F72395ADFP#V0 supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message RAM, transmit/receive FIFOs, and programmable bit timing. These interfaces operate concurrently and support standard CAN protocols used in J1939 and CANopen networks. The R5F72395ADFP#V0 does not support CAN FD; for FD capability, Renesas' RX72M series is recommended as an alternative.

What package type is used for the R5F72395ADFP#V0?

The R5F72395ADFP#V0 is housed in a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm pin pitch. This package provides robust thermal dissipation and mechanical reliability for industrial environments. Pin assignments include dedicated analog/digital power domains, isolated CAN transceiver I/O, and grouped peripheral signals to simplify PCB layout and reduce crosstalk-key considerations in the R5F72395ADFP#V0's target applications.

Is the R5F72395ADFP#V0 qualified for functional safety standards?

Yes, the R5F72395ADFP#V0 includes multiple hardware features supporting IEC 61508 SIL2 and ISO 26262 ASIL B compliance, including ECC-protected SRAM, Flash BIST, lock-step watchdog timer, and memory parity checking. While the R5F72395ADFP#V0 itself is not pre-certified, Renesas provides safety manuals, FMEDA reports, and diagnostic software libraries enabling system-level certification. Customers must implement these features per their safety architecture to achieve certified operation.
