Renesas R5F72147GDFP#H1

Overview

R5F72147GDFP#H1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 1 MB of on-chip 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 R5F72147GDFP#H1 datasheet, R5F72147GDFP#H1 pinout, R5F72147GDFP#H1 application, or R5F72147GDFP#H1 equivalent, key selection criteria include its 144-pin LQFP package, CAN 2.0B compliance, 80 MHz max CPU clock, and support for single-chip mode with external bus interface disabled - critical for compact, cost-sensitive control designs.

Technical Context

The R5F72147GDFP#H1 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction. It integrates a Clock Pulse Generator (CPG) supporting PLL-based clock synthesis, multiple operating modes (including Single Chip Mode), and hardware exception handling with vectorized interrupt controller (INTC).

Peripheral integration includes a Data Transfer Controller (DTC) for zero-CPU-overhead data movement, a Watchdog Timer (WDT) with windowed operation, and dual-channel CAN controllers compliant with ISO 11898-1. Memory protection is enforced via an on-chip memory management unit (MMU)-like address space partitioning, though no full MMU is present.

FAQ

What is the maximum operating frequency of the R5F72147GDFP#H1?

The R5F72147GDFP#H1 operates at a maximum CPU frequency of 80 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL support. This frequency is confirmed in the SH7214 Group Hardware User's Manual Rev. 4.00 and defines the upper bound for instruction execution speed, peripheral bus timing, and real-time loop performance in applications such as motor control. The R5F72147GDFP#H1 requires stable clock source configuration (e.g., crystal + PLL settings) to sustain this rate reliably.

Does the R5F72147GDFP#H1 support CAN FD or only classical CAN 2.0B?

The R5F72147GDFP#H1 supports only CAN 2.0B (ISO 11898-1), not CAN FD. Its dual CAN controllers implement standard 11-bit and 29-bit identifier messaging with message object buffers and error counters, as documented in the SH7214 Group Hardware User's Manual. CAN FD features such as variable bit rate and extended data length are absent; users requiring CAN FD must select a newer Renesas RA or RH850 family device. The R5F72147GDFP#H1 remains fully interoperable with legacy CAN networks.

What debug interface does the R5F72147GDFP#H1 provide?

The R5F72147GDFP#H1 includes an IEEE 1149.1-compliant JTAG interface supporting boundary scan, real-time trace, and full on-chip debugging - no external debug probe required beyond standard JTAG cabling. This interface enables halt/resume, register inspection, flash programming, and real-time variable monitoring during development. The R5F72147GDFP#H1 does not support SWD or Serial Wire Debug; JTAG is the sole standardized debug path specified in Renesas documentation.

Is the R5F72147GDFP#H1 pin-compatible with other SH7214 Group devices?

Yes, the R5F72147GDFP#H1 is pin-compatible with other 144-pin LQFP variants in the SH7214 Group, including R5F72146GDFP#H1 and R5F72148GDFP#H1. All share identical pin assignments, electrical characteristics, and peripheral mappings per the SH7214 Group Hardware User's Manual. This allows direct PCB reuse across memory variants - only Flash/RAM size and part marking differ. The R5F72147GDFP#H1 requires no layout changes when substituted within this family.

What is the qualified temperature range for the R5F72147GDFP#H1?

The R5F72147GDFP#H1 is rated for industrial temperature operation from −40 °C to +85 °C, consistent with Renesas' "Standard" quality grade classification. This range is validated per JEDEC JESD22-A104 and applies to continuous operation under specified voltage and load conditions. The R5F72147GDFP#H1 is not qualified for automotive AEC-Q100 or extended temperature grades; use in transportation equipment requires explicit validation and written consent from Renesas Electronics.
