Renesas R5F72147ADFA#V1

Overview

R5F72147ADFA#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 1 MB of on-chip Flash memory, 128 KB RAM, and integrated peripherals including USB 2.0 FS host/device, CAN controller, 12-bit ADC (24 channels), and MTU2S timer units. It operates at up to 120 MHz and targets automotive body control modules and industrial motor control systems.

For engineers reviewing the R5F72147ADFA#V1 datasheet, R5F72147ADFA#V1 pinout, R5F72147ADFA#V1 application, or R5F72147ADFA#V1 equivalent, key selection criteria include Flash endurance (100k write/erase cycles), CAN FD readiness via software configuration, USB suspend/resume timing compliance, and support for -40°C to +105°C extended temperature operation in automotive-grade packaging.

Technical Context

The R5F72147ADFA#V1 implements the SH-2A CPU core with FPU support and executes instructions in a five-stage pipeline with branch prediction. It integrates a Clock Pulse Generator (CPG) supporting PLL-based clock synthesis from 1–20 MHz crystal inputs, enabling configurable system clocks up to 120 MHz and peripheral clocks down to 30 kHz for low-power modes.

Its interrupt architecture uses a programmable priority-level INTC with 192 vector entries, supporting nested interrupts and fast context switching. Peripheral functions are memory-mapped into a unified 32-bit address space, with dedicated DMA channels (DTC) for high-throughput data movement between USB, CAN, ADC, and memory without CPU intervention.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the R5F72147ADFA#V1?

The R5F72147ADFA#V1 operates at a maximum CPU frequency of 120 MHz, achieved using its on-chip PLL-based Clock Pulse Generator (CPG) with configurable multiplication/division ratios. This frequency is sustained across the full -40°C to +105°C operating range when supplied with 3.3 V ±10%, and is validated per Renesas' electrical characteristics testing in the SH7214 Group Hardware User's Manual Rev.4.00.

Does the R5F72147ADFA#V1 support CAN FD?

The R5F72147ADFA#V1 includes a classical CAN 2.0B controller compliant with ISO 11898-1:2003 but does not support CAN FD physical layer or protocol enhancements. CAN FD functionality requires external transceivers and software-layer arbitration-no native bit-rate switching or extended data length support is implemented in the R5F72147ADFA#V1's CAN module.

What debug interface does the R5F72147ADFA#V1 provide?

The R5F72147ADFA#V1 provides a full IEEE 1149.1 JTAG interface supporting boundary scan, real-time instruction trace, hardware breakpoints, and watchpoints. It enables non-intrusive debugging without CPU halting, and is compatible with Renesas E2 emulator and third-party tools supporting SH-2A core debug protocols.

Is the R5F72147ADFA#V1 qualified for automotive applications?

Yes, the R5F72147ADFA#V1 is AEC-Q100 Grade 2 qualified (-40°C to +105°C) and classified as a "High Quality" product per Renesas' quality grading system. It is intended for automotive body electronics, chassis systems, and industrial equipment-not for safety-critical life-support or aerospace applications.

How much user-accessible Flash memory does the R5F72147ADFA#V1 have?

The R5F72147ADFA#V1 provides 1,048,576 bytes (1 MB) of on-chip Flash memory accessible for user code and data storage. This includes support for block erase (minimum 1 KB), page programming, and 100,000 write/erase cycles per block, as specified in the SH7214 Group Hardware User's Manual Rev.4.00.
