FAQ

What is the maximum operating frequency of the R5F72167GDFA#V1?

The R5F72167GDFA#V1 operates at a maximum CPU frequency of 120 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL-based frequency multiplication from external crystal (1–20 MHz) or clock input. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) under 3.0–3.6 V supply conditions, as verified in the SH7216 Group Hardware User's Manual Rev.4.00.

Does the R5F72167GDFA#V1 include an integrated USB physical layer?

Yes, the R5F72167GDFA#V1 integrates a full-speed USB 2.0 PHY with on-chip termination and VBUS detection circuitry. This eliminates the need for an external USB transceiver and supports both host and device modes. The USB clock is generated internally at 48 MHz using a dedicated CPG path, as documented in Section 4.8 of the SH7216 Group Hardware User's Manual.

How many CAN interfaces does the R5F72167GDFA#V1 support, and what protocol versions are implemented?

The R5F72167GDFA#V1 supports two independent CAN controllers compliant with ISO 11898-1:2003 (Classical CAN), each with 32-message RAM, hardware acceptance filtering, and bit rates up to 1 Mbit/s. Neither controller supports CAN FD; they are strictly Classical CAN per the SH7216 Group peripheral specification in the Hardware User's Manual Rev.4.00.

What is the ADC resolution and channel count of the R5F72167GDFA#V1, and how is sampling triggered?

The R5F72167GDFA#V1 features a 12-bit successive-approximation ADC with 24 input channels. Sampling can be initiated by software command, external trigger (e.g., GPIO), or hardware synchronization from MTU2S timer compare match events-enabling precise phase-aligned acquisition in motor control. Conversion time is 1.0 µs at maximum speed, as specified in the electrical characteristics section of the Hardware User's Manual.

Is the R5F72167GDFA#V1 qualified for industrial temperature operation?

Yes, the R5F72167GDFA#V1 is rated for industrial temperature operation from −40°C to +85°C, consistent with Renesas' "Standard" quality grade classification per their general precautions documentation. This rating applies to all specified electrical characteristics and timing parameters, and the device meets JEDEC JESD22-A104 reliability testing requirements for industrial environments.
