It operates at up to 120 MHz and targets automotive body electronics and industrial control applications requiring real-time performance and functional safety support.
For engineers reviewing the R5F72147GDBG#U1 datasheet, R5F72147GDBG#U1 pinout, R5F72147GDBG#U1 application, or R5F72147GDBG#U1 equivalent, key selection criteria include its SH-2A CPU core compliance with ISO 26262 ASIL-B readiness, 120 MHz max clock frequency, 1 MB Flash with ECC, dual CAN interfaces, and 176-pin LQFP package with dedicated safety monitoring pins (e.g., BSC, WDT, and clock fail-detection circuitry).
Technical Context
The R5F72147GDBG#U1 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction and 16 KB instruction/16 KB data cache. It integrates a Clock Pulse Generator (CPG) supporting PLL-based clock synthesis, oscillation stop detection, and USB 48-MHz clock generation via internal or external resonator.
Peripheral integration includes a Data Transfer Controller (DTC) for autonomous DMA transfers, Interrupt Controller (INTC) with 256 interrupt sources and priority levels, and Bus State Controller (BSC) enabling external memory expansion with wait-state control and bus arbitration-critical for multi-master systems in automotive gateway designs.

FAQ
What is the maximum operating frequency of the R5F72147GDBG#U1?
The R5F72147GDBG#U1 operates at a maximum frequency of 120 MHz using its internal PLL with an external crystal or clock source. This frequency is achievable across the full −40 °C to +105 °C temperature range when powered within the specified 3.0 V to 3.6 V supply voltage. The CPG module allows dynamic clock scaling for power optimization without compromising real-time responsiveness in the R5F72147GDBG#U1.
Does the R5F72147GDBG#U1 support CAN FD?
No, the R5F72147GDBG#U1 supports CAN 2.0B only, with two independent CAN controllers compliant with ISO 11898-1. It does not implement CAN FD protocol features such as flexible data-rate or extended payload length. For CAN FD capability, Renesas recommends the pin-compatible R5F72148GDBG#U1, which adds CAN FD support while retaining identical packaging and core architecture as the R5F72147GDBG#U1.
What safety certifications apply to the R5F72147GDBG#U1?
The R5F72147GDBG#U1 is designed to support ISO 26262 ASIL-B compliance through hardware features including ECC on Flash and RAM, clock failure detection, watchdog timer with windowing, and bus state monitoring. While the device itself is not pre-certified, Renesas provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate ASIL-B system certification. These resources are documented specifically for the R5F72147GDBG#U1 in the SH7214 Group Hardware User's Manual.
Is USB functionality available on the R5F72147GDBG#U1?
Yes, the R5F72147GDBG#U1 integrates a USB 2.0 Full-Speed device controller with an on-chip PHY, supporting data rates up to 12 Mbps. It includes dedicated pins (USB_DP, USB_DM, USB_VBUS) and firmware libraries for CDC and HID class implementations. The USB module operates independently of the main CPU clock and supports suspend/resume states, making it suitable for diagnostic interfaces and firmware updates in the R5F72147GDBG#U1.
What development tools are supported for the R5F72147GDBG#U1?
Renesas provides the e2 studio IDE with CS+ compiler support, SH-2A-specific debug probes (E2 emulator Lite), and comprehensive HAL drivers for the R5F72147GDBG#U1. Third-party tools including IAR Embedded Workbench and Green Hills MULTI also support this device.
