Renesas R5F72147BDFA#V1

Overview

R5F72147BDFA#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 1 MB Flash memory, 64 KB RAM, and integrated peripherals including CAN, SCI, I²C, and 12-bit ADC. It operates at up to 80 MHz and targets industrial motor control and embedded automation systems requiring deterministic real-time response.

For engineers reviewing the R5F72147BDFA#V1 datasheet, R5F72147BDFA#V1 pinout, R5F72147BDFA#V1 application, or R5F72147BDFA#V1 equivalent, key selection criteria include its SH-2A CPU architecture, 100-pin LQFP package, CAN 2.0B compliance, 80 MHz max clock, and industrial temperature range (−40°C to +85°C).

Technical Context

The R5F72147BDFA#V1 implements the SH-2A superscalar RISC core with dual-issue capability, supporting both integer and floating-point operations via integrated FPU. It integrates a Clock Pulse Generator (CPG) with PLL, multiple timer units (MTU2S, WDT), and a Data Transfer Controller (DTC) for autonomous peripheral-to-memory transfers without CPU intervention.

Peripheral integration includes two CAN controllers compliant with ISO 11898-1, four asynchronous serial interfaces (SCI), one I²C bus interface, and a 12-channel 12-bit ADC with sample-and-hold. Memory protection is enforced via an on-chip memory protection unit (MPU), and boot operation supports single-chip mode with internal Flash execution.

FAQ

What is the maximum operating frequency of the R5F72147BDFA#V1?

The R5F72147BDFA#V1 operates at a maximum CPU frequency of 80 MHz, achieved via its on-chip Clock Pulse Generator (CPG) with PLL circuitry. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) when powered within specified voltage rails (3.0 V to 3.6 V). The R5F72147BDFA#V1 achieves this performance using the SH-2A superscalar core with dual-issue pipeline and integrated FPU, enabling high instruction-per-cycle throughput for real-time control tasks.

Does the R5F72147BDFA#V1 support CAN FD?

No, the R5F72147BDFA#V1 supports only Classical CAN (ISO 11898-1, CAN 2.0B) at up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length (up to 64 bytes), or bit-rate switching. Its two CAN controllers are fully compatible with legacy CAN networks used in industrial automation and motor drives, but cannot interoperate with CAN FD nodes without external protocol translation. The R5F72147BDFA#V1 datasheet and hardware manual confirm this limitation explicitly in the peripheral specifications section.

What debug interface does the R5F72147BDFA#V1 use?

The R5F72147BDFA#V1 uses the standard Renesas E2000/E2 emulator interface via the 14-pin JTAG connector (pins 93–100, including TDI, TDO, TCK, TMS, TRST, and nSRST). It supports full-speed real-time debugging, flash programming, and boundary-scan testing. The R5F72147BDFA#V1 does not integrate SWD or cJTAG; JTAG is the sole supported debug transport. Debug capabilities include hardware breakpoints, watchpoints, and register visibility through compatible Renesas E2 studio and CS+ toolchains.

Is the R5F72147BDFA#V1 qualified for automotive applications?

No, the R5F72147BDFA#V1 is rated for industrial applications only (Standard quality grade per Renesas classification) and is not AEC-Q100 qualified. It lacks automotive-specific qualifications such as extended temperature range (−40°C to +125°C), enhanced ESD immunity, and failure-in-time (FIT) rate certification. While it may function in benign automotive environments, Renesas explicitly restricts its use to computers, office equipment, industrial robots, and factory automation - not transportation equipment. For automotive use, consider Renesas RH850 or RL78/F1x series instead of the R5F72147BDFA#V1.

What is the Flash endurance and data retention specification for the R5F72147BDFA#V1?

The R5F72147BDFA#V1 specifies 10,000 write/erase cycles minimum for its on-chip Flash memory, with data retention guaranteed for 20 years at +85°C or 100 years at +25°C ambient. These values are measured per Renesas' standard Flash qualification methodology and apply to all 1024 KB of user-programmable Flash. Sector erase (minimum 1 KB) and byte/word programming are supported. The R5F72147BDFA#V1 includes built-in ECC for single-bit error correction and double-bit error detection during read operations, enhancing reliability in long-life industrial deployments.
