FAQ

What is the maximum operating frequency of the R5F72395ADFP#H0?

The R5F72395ADFP#H0 operates at a maximum frequency of 100 MHz. This clock speed is achieved using the on-chip clock pulse generator (CPG) with PLL multiplication of an external crystal or oscillator input. At this frequency, the SH-2A core delivers 165 DMIPS, enabling hard real-time execution of complex control algorithms such as field-oriented control in motor drive applications. The R5F72395ADFP#H0 maintains timing compliance across its full industrial temperature range (−40°C to +85°C) when powered within the specified 3.0 V to 3.6 V supply range.

Does the R5F72395ADFP#H0 include a hardware floating-point unit?

Yes, the R5F72395ADFP#H0 integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This FPU accelerates transcendental and arithmetic operations essential for motor control algorithms like Clarke/Park transforms and PI regulator calculations. Unlike software-emulated floating-point, the hardware FPU in the R5F72395ADFP#H0 executes these operations in-cycle, reducing latency and freeing CPU bandwidth for other real-time tasks. The R5F72395ADFP#H0's FPU is accessible via dedicated instructions documented in the SH-2A Software Manual (REJ09B0086).

What communication interfaces are supported by the R5F72395ADFP#H0?

The R5F72395ADFP#H0 supports CAN 2.0B, multiple SCI (UART) channels, I²C-compatible serial interface (RSPI), and inter-equipment bus (IEBus). Its dual CAN controllers enable redundant or multi-network operation in industrial automation, while six SCI modules support simultaneous debug, host communication, and peripheral bridging. The R5F72395ADFP#H0 does not include Ethernet or USB peripherals. All interfaces are mapped to dedicated GPIO pins with configurable alternate functions and support asynchronous clocking - ensuring reliable operation in electrically noisy environments typical of motor drive applications.

How much on-chip memory does the R5F72395ADFP#H0 provide?

The R5F72395ADFP#H0 integrates 1 MB of on-chip Flash memory and 128 KB of RAM. The Flash is organized into blocks supporting page erase and word programming, with built-in error correction code (ECC) for enhanced reliability during firmware updates. The RAM includes both general-purpose SRAM and dedicated areas for stack and peripheral buffers. This memory configuration allows the R5F72395ADFP#H0 to host full-featured motor control firmware with dual-bank update capability and real-time data logging - eliminating the need for external memory in most industrial embedded designs.

Is the R5F72395ADFP#H0 pin-compatible with other SH7239 Group MCUs?

No, the R5F72395ADFP#H0 is not universally pin-compatible across the SH7239 Group. While it shares the same 144-pin LQFP package with several variants (e.g., R5F72394ADFP#H0), pin assignments differ for certain peripherals - particularly ADC input channels and MTU output terminals - due to variant-specific feature enablement. For example, the R5F72395ADFP#H0 exposes all 24 ADC channels and six MTU output pairs, whereas lower-memory variants may repurpose some pins as general-purpose I/O. Always verify pin mapping against the specific device's "Pin Assignment" section in the SH7239 Group Hardware User's Manual before board layout. The R5F72395ADFP#H0 itself has a fixed, documented pinout that must be followed precisely.
