FAQ

What is the maximum operating frequency of the HD64F7047FW40V?

The HD64F7047FW40V operates at a maximum frequency of 40 MHz. This speed is achieved using an external crystal or clock source connected to the CLKIN/EXTAL pins, with internal PLL circuitry generating the core clock. At this frequency, the SH-2 CPU delivers deterministic real-time performance with worst-case interrupt latency under 1.5 µs - critical for motor control and industrial automation applications where timing precision is essential. The HD64F7047FW40V maintains full functionality across its specified industrial temperature range (–40°C to +85°C) at this speed.

Does the HD64F7047FW40V include on-chip Flash memory, and what is its endurance rating?

Yes, the HD64F7047FW40V integrates 256 KB of on-chip Flash memory. Its endurance is rated for 10,000 write/erase cycles per sector, verified per Renesas' qualification testing. This allows reliable in-field firmware updates and parameter storage without external nonvolatile memory. The Flash supports sector erase and byte programming, enabling efficient use in applications such as automated test equipment where calibration data must be updated regularly. HD64F7047FW40V Flash architecture also permits read-while-write operation, minimizing system interruption during updates.

How many CAN interfaces does the HD64F7047FW40V support, and are they CAN 2.0B-compliant?

The HD64F7047FW40V supports two independent CAN interfaces, both fully compliant with the ISO 11898-1:2003 CAN 2.0B specification. Each channel features 32 message objects with hardware acceptance filtering, programmable bit timing (up to 1 Mbps), and automatic retransmission on error. These interfaces operate autonomously - allowing HD64F7047FW40V to serve as a bridge between separate CAN networks (e.g., control bus and diagnostics bus) without CPU intervention. No external CAN controller or transceiver is required beyond the physical layer device.

What package type and pin count does the HD64F7047FW40V use?

The HD64F7047FW40V is packaged in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch and dimensions of 14 mm × 20 mm. This RoHS-compliant package supports standard surface-mount reflow processes and provides dedicated power/ground pairs per functional block to suppress noise coupling. Pin assignments match the SH7047 family's standardized layout - ensuring compatibility with existing SH7047F reference designs and evaluation boards. The HD64F7047FW40V PQFP footprint is documented in Appendix A of the SH7047 Group Hardware Manual (Rev. 2.00).

Is the HD64F7047FW40V suitable for safety-critical applications such as medical or automotive systems?

The HD64F7047FW40V is classified as a "Standard" quality grade device per Renesas' product categorization, intended for applications including industrial automation, office equipment, and communications systems. It is not qualified for "High Quality" or "Specific" applications - such as automotive powertrain, medical life-support, or aerospace systems - without prior written consent from Renesas Electronics. For HD64F7047FW40V deployment in regulated environments, users must perform their own functional safety assessment and obtain formal approval from Renesas. The device lacks ASIL or IEC 61508 certification out of the box.
