FAQ

What is the maximum operating frequency of the DF71374AD80FPV#GZ?

The DF71374AD80FPV#GZ operates at a maximum frequency of 80 MHz, achieved via its on-chip PLL using an external 1–20 MHz crystal or clock source. This frequency is fully supported across the entire −40°C to +85°C operating temperature range and under all specified supply voltage conditions (3.0–3.6 V). The DF71374AD80FPV#GZ maintains instruction timing compliance without derating at this speed.

Does the DF71374AD80FPV#GZ include CAN interface support?

Yes, the DF71374AD80FPV#GZ integrates two independent CAN 2.0B controllers compliant with ISO 11898-1. Each channel supports bit rates up to 1 Mbps, message filtering, FIFO buffering, and automatic retransmission. These controllers are accessible via dedicated CAN_TX/CAN_RX pins and require external transceivers for physical layer implementation. The DF71374AD80FPV#GZ uses these interfaces for industrial fieldbus communication and diagnostics.

What package type and pin count does the DF71374AD80FPV#GZ use?

The DF71374AD80FPV#GZ is housed in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with an exposed thermal pad. This JEDEC MS-026AC-compliant package supports standard reflow soldering profiles and provides adequate thermal dissipation for continuous operation at 80 MHz. Pin assignments-including VCC, VSS, CLKIN, RESET, UART, and CAN signals-are documented in the SH7137 Group Hardware Manual Rev. 3.00.

Is the DF71374AD80FPV#GZ qualified for industrial temperature operation?

Yes, the DF71374AD80FPV#GZ is rated for industrial temperature operation from −40°C to +85°C ambient. This qualification applies to all electrical specifications-including Flash endurance, RAM retention, clock stability, and I/O drive strength-as verified in Renesas' characterization testing. The device meets Renesas' "Standard" quality grade per their product classification, making it suitable for industrial robots, machine tools, and factory automation equipment.

Does the DF71374AD80FPV#GZ support in-system programming of its Flash memory?

Yes, the DF71374AD80FPV#GZ supports in-application programming (IAP) of its 512 KB on-chip Flash memory via its built-in bootloader. Programming is performed through UART or CAN interfaces using Renesas' Flash Development Toolkit (FDT) or custom host software. The DF71374AD80FPV#GZ allows sector-by-sector erasure and byte/word programming with hardware-assisted checksum verification, enabling field firmware updates without external programmers.
