Renesas R5F72165GDFA#V1

Overview

R5F72165GDFA#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 512 KB on-chip Flash memory, 64 KB RAM, and integrated peripherals including SCI, I²C, CAN, and 12-bit ADC. It operates at up to 100 MHz and targets industrial motor control and embedded automation systems requiring real-time deterministic response.

For engineers reviewing the R5F72165GDFA#V1 datasheet, R5F72165GDFA#V1 pinout, R5F72165GDFA#V1 application, or R5F72165GDFA#V1 equivalent, key selection considerations include its SH-2A CPU architecture, 100 MHz max clock, CAN 2.0B interface, 12-bit ADC with 16 channels, and support for single-chip and extended MCU operating modes.

Technical Context

The R5F72165GDFA#V1 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 data transfer controller (DTC) for autonomous peripheral-to-memory transfers without CPU intervention.

Peripheral integration includes two CAN controllers compliant with ISO 11898-1, a 12-bit successive-approximation ADC with sample-and-hold and hardware-triggered conversion sequencing, and six serial communication interfaces (SCI) supporting UART, LIN, and IrDA protocols - all mapped to dedicated I/O ports with configurable drive strength and pull-up/down control.

FAQ

What is the maximum operating frequency of the R5F72165GDFA#V1?

The R5F72165GDFA#V1 operates at a maximum CPU frequency of 100 MHz using its on-chip PLL clock pulse generator. This frequency is achieved with an external crystal (e.g., 8 MHz) multiplied internally, and the device maintains timing compliance across the full −40 °C to +85 °C industrial temperature range. The R5F72165GDFA#V1's SH-2A core sustains dual-issue instruction throughput at this speed, enabling sub-microsecond interrupt response critical for motor control.

Does the R5F72165GDFA#V1 support CAN FD or only classical CAN 2.0B?

The R5F72165GDFA#V1 supports only Classical CAN 2.0B (ISO 11898-1) - not CAN FD. Its two CAN controllers implement message objects with identifier masking, FIFO buffering, and error counters, but lack the variable bit-rate arbitration and extended data length features of CAN FD. For CAN FD applications, designers must select a newer Renesas RA or RH850 series device. The R5F72165GDFA#V1 remains fully compatible with legacy industrial CAN networks.

What is the ADC resolution and sampling rate of the R5F72165GDFA#V1?

The R5F72165GDFA#V1 integrates a 12-bit successive-approximation ADC with 16 input channels and a minimum conversion time of 1.25 µs per sample. It supports hardware-triggered sequential conversion across multiple channels, enabling synchronized sampling for three-phase current reconstruction. The ADC includes internal reference voltage and calibration registers, and its performance is specified across the full industrial temperature range. This ADC capability is central to the R5F72165GDFA#V1's role in precision motor control systems.

Is the R5F72165GDFA#V1 pin-compatible with other SH7216 series microcontrollers?

Yes, the R5F72165GDFA#V1 is pin-compatible with other members of the SH7216 Group in the same 144-pin LQFP package (e.g., R5F72164GDFA#V1, R5F72166GDFA#V1). Pin assignments for power, clocks, reset, peripherals, and I/O are identical across these variants. This allows direct substitution on existing PCBs when memory or peripheral requirements change - provided the firmware is recompiled for the target variant's memory map and feature set. The R5F72165GDFA#V1 serves as the mid-tier option in this scalable family.

What development tools are officially supported for the R5F72165GDFA#V1?

Renesas provides official support for the R5F72165GDFA#V1 through the e2 studio IDE with CS+ compiler toolchain, and the E2 emulator Lite for debugging. Hardware evaluation is enabled by the YRDKSH7216 development kit, which includes a daughterboard with motor control interface, CAN transceivers, and ADC signal conditioning. Renesas also publishes application notes covering FOC implementation, CAN network initialization, and DTC-based ADC data streaming - all validated on the R5F72165GDFA#V1 platform.
