Renesas R5F72165BDFA#V1

Overview

R5F72165BDFA#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 deterministic real-time response.

For engineers reviewing the R5F72165BDFA#V1 datasheet, R5F72165BDFA#V1 pinout, R5F72165BDFA#V1 application, or R5F72165BDFA#V1 equivalent, key selection criteria include its SH-2A CPU architecture, 100 MHz max frequency, CAN 2.0B interface support, 12-bit ADC with 16 channels, and 100-pin LQFP package with industrial temperature range (−40°C to +85°C).

Technical Context

The R5F72165BDFA#V1 implements the SH-2A superscalar RISC core with dual-issue pipeline, supporting both integer and floating-point operations via integrated FPU. It integrates a Clock Pulse Generator (CPG) with PLL for flexible clock synthesis, and a Data Transfer Controller (DTC) enabling autonomous peripheral-to-memory transfers without CPU intervention.

Its system architecture includes a Bus State Controller (BSC) for external bus interfacing, an Interrupt Controller (INTC) with 128 interrupt sources and programmable priority levels, and a Watchdog Timer (WDT) with windowed operation mode. Peripheral integration supports simultaneous real-time control tasks - e.g., PWM generation via MTU2S timers while sampling analog inputs via ADC and communicating over CAN.

FAQ

What is the maximum operating frequency of the R5F72165BDFA#V1?

The R5F72165BDFA#V1 operates at a maximum frequency of 100 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL circuitry. This frequency enables the SH-2A core to deliver 190 MIPS, supporting demanding real-time tasks such as vector-controlled motor drives and multi-axis synchronization. The R5F72165BDFA#V1 achieves this speed across its full industrial temperature range (−40°C to +85°C) under 3.3 V supply conditions.

Does the R5F72165BDFA#V1 support CAN communication?

Yes, the R5F72165BDFA#V1 integrates a CAN 2.0B-compliant controller supporting bit rates up to 1 Mbps. It includes message objects, acceptance filtering, and error handling logic, but requires an external CAN transceiver (e.g., TJA1042) for physical layer connection. The R5F72165BDFA#V1 does not support CAN FD; that capability is available in the higher-memory R5F72166BDFA#V1 variant.

What development tools are supported for the R5F72165BDFA#V1?

Renesas provides the e2 studio IDE with CS+ compiler support, along with the E2 emulator Lite for debugging the R5F72165BDFA#V1 via its IEEE 1149.1 JTAG interface. Renesas also offers the SH7216 Group Starter Kit (YRDKSH7216) with example projects for motor control and CAN communication. The R5F72165BDFA#V1 is fully supported in Renesas' AP4 and AP6 peripheral driver libraries.

Is the R5F72165BDFA#V1 qualified for industrial temperature operation?

Yes, the R5F72165BDFA#V1 is rated for operation from −40°C to +85°C and is classified as a "Standard" quality grade device per Renesas' product grading system. It is intended for industrial applications including motor drives, factory automation, and energy infrastructure - but not for automotive, medical life-support, or aerospace use without explicit Renesas approval.

How much on-chip memory does the R5F72165BDFA#V1 include?

The R5F72165BDFA#V1 includes 512 KB of on-chip Flash memory for program storage and 64 KB of RAM for data and stack operations. Both memory blocks are accessible via the internal bus with zero wait states at 100 MHz. The Flash supports block erase, byte/word programming, and read-out protection - essential for secure firmware deployment in the R5F72165BDFA#V1's target applications.
