It operates at up to 100 MHz and targets industrial control and automotive body electronics applications requiring deterministic real-time performance.

For engineers reviewing the R5F72147BDFP#V1 datasheet, R5F72147BDFP#V1 pinout, R5F72147BDFP#V1 application, or R5F72147BDFP#V1 equivalent, key selection criteria include CAN interface support, Flash memory endurance (100K write/erase cycles), operating temperature range (−40°C to +85°C), and compliance with AEC-Q100 Grade 2 for automotive use.

Technical Context

The R5F72147BDFP#V1 implements the SH-2A CPU core with FPU support, enabling single-precision floating-point operations and 32-bit integer arithmetic. 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.

Its system architecture includes a Bus State Controller (BSC) supporting external memory expansion, an Interrupt Controller (INTC) with 128 interrupt sources and 7 priority levels, and a CAN controller compliant with ISO 11898-1:2003 supporting both standard and extended frames with 32 message buffers.

FAQ

What is the maximum operating frequency of the R5F72147BDFP#V1?

The R5F72147BDFP#V1 operates at a maximum CPU frequency of 100 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL. This frequency is sustained across the full −40°C to +85°C industrial temperature range when supplied with 2.7 V to 5.5 V, and is confirmed in the "Electrical Characteristics" section of the official Renesas Hardware User's Manual Rev. 4.00.

Does the R5F72147BDFP#V1 support CAN FD or only classical CAN 2.0B?

The R5F72147BDFP#V1 supports only CAN 2.0B (ISO 11898-1:2003), not CAN FD. Its CAN controller implements standard and extended frame formats, bit rates up to 1 Mbit/s, and 32 message objects-but lacks the variable data length, bit rate switching, and CRC enhancements defined in CAN FD. This is explicitly documented in Section 12.1 of the SH7214 Group Hardware Manual.

Is the R5F72147BDFP#V1 qualified to AEC-Q100 standards?

Yes, the R5F72147BDFP#V1 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C junction temperature), as verified in Renesas' official product change notices and packaging documentation. This qualification covers stress testing for HTOL, TC, UHAST, and ESD-making it suitable for under-hood automotive body electronics applications.

What debugging interface does the R5F72147BDFP#V1 provide?

The R5F72147BDFP#V1 features the FULL-TRACE™ on-chip debug interface, supporting real-time instruction trace, hardware breakpoints, watchpoints, and memory access monitoring via the dedicated JTAG/SWD pins. This interface is fully compatible with Renesas E2 emulator and third-party tools like Lauterbach TRACE32, as detailed in Chapter 20 of the Hardware User's Manual.

Does the R5F72147BDFP#V1 include hardware encryption accelerators?

No, the R5F72147BDFP#V1 does not include dedicated hardware encryption accelerators (e.g., AES, SHA, or RSA engines). Security functions rely on software libraries executed on the SH-2A core. For cryptographic offload, Renesas recommends pairing the R5F72147BDFP#V1 with external secure elements or migrating to the RA6T2 or RH850/F1KM series, which integrate TRNG and AES-128 accelerators.
