It operates at up to 80 MHz and targets industrial control and motor drive applications requiring deterministic real-time response.

For engineers reviewing the R5F72165ADFP#H1 datasheet, R5F72165ADFP#H1 pinout, R5F72165ADFP#H1 application, or R5F72165ADFP#H1 equivalent, key selection criteria include its SH-2A CPU architecture, CAN 2.0B interface support, 80 MHz max clock, 512 KB Flash with ECC, and 100-pin LQFP package with dedicated motor control timer resources.

Technical Context

The R5F72165ADFP#H1 implements the SH-2A superscalar RISC core with dual-issue capability, supporting both integer and floating-point operations via integrated FPU. Its system architecture includes a bus controller (BSC), clock pulse generator (CPG) with PLL and multiple clock domains, and interrupt controller (INTC) with 128 vector entries.

Peripheral integration centers on real-time control: MTU2S provides six-channel complementary PWM output with dead-time insertion and synchronous A/D trigger; the CAN module supports full CAN 2.0B protocol with 32 message objects and programmable bit timing; and the 10-bit ADC offers 24 channels with scan mode and hardware-triggered conversion sequencing.

FAQ

What is the maximum operating frequency of the R5F72165ADFP#H1?

The R5F72165ADFP#H1 operates at a maximum CPU frequency of 80 MHz, achieved using the on-chip CPG with PLL. This frequency is supported across the full industrial temperature range (−40°C to +85°C) when supplied with 3.3 V ±10% and proper decoupling. The R5F72165ADFP#H1's SH-2A core sustains dual-issue throughput at this speed, enabling deterministic execution of control algorithms.

Does the R5F72165ADFP#H1 include error-correcting code (ECC) for its Flash memory?

Yes, the R5F72165ADFP#H1 integrates ECC protection across its entire 512 KB on-chip Flash memory. This provides single-bit error correction and double-bit error detection, which is essential for maintaining firmware integrity in electrically noisy industrial environments. The ECC logic is transparent to software and automatically applied during all Flash read operations - a key reliability feature distinguishing the R5F72165ADFP#H1 from lower-tier variants like the R5F72164ADFP#H1.

Which peripherals in the R5F72165ADFP#H1 support hardware synchronization for motor control?

The R5F72165ADFP#H1 supports hardware synchronization between its MTU2S timer and 10-bit ADC via dedicated ADTRGx pins. When configured, MTU2S events (e.g., PWM center-aligned zero-crossing) can trigger ADC conversions without CPU intervention - ensuring precise, jitter-free current sampling aligned to inverter switching. This capability is explicitly documented in Section 4.4.3 (ACLKCR) and Section 14.3 of the SH7216 Hardware User's Manual for the R5F72165ADFP#H1.

Is the R5F72165ADFP#H1 pin-compatible with other devices in the SH7216 Series?

Yes, the R5F72165ADFP#H1 shares the same 100-pin LQFP package and pin assignment with other members of the SH7216 Group, including the R5F72164ADFP#H1 and R5F72166ADFP#H1. This allows direct PCB reuse across variants differing only in Flash/RAM size or peripheral enablement - provided the target application does not require features disabled in the specific variant (e.g., second CAN channel in R5F72166ADFP#H1).

What development tools are officially supported for the R5F72165ADFP#H1?

Renesas provides full toolchain support for the R5F72165ADFP#H1, including the CS+ IDE with C/C++ compiler, E2 emulator Lite for debugging, and the Renesas Flash Programmer for programming. Application notes such as "R01AN1379EJ0200 SH7216 Motor Control Solution" and the SH7216 Group Hardware User's Manual (Rev.4.00) are validated for the R5F72165ADFP#H1. No third-party toolchain certification is required - the R5F72165ADFP#H1 is fully supported out-of-box.
