FAQ

What is the maximum operating frequency of the R5F72165ADFP#V1?

The R5F72165ADFP#V1 operates at a maximum CPU frequency of 64 MHz, achieved via its on-chip Clock Pulse Generator (CPG) with PLL. This frequency is confirmed in Section 4.3 "Clock Operating Modes" of the SH7214/SH7216 Hardware User's Manual (Rev. 4.00). At 64 MHz, the R5F72165ADFP#V1 delivers consistent instruction throughput for real-time motor control loops and communication stack processing without jitter-induced timing violations.

Does the R5F72165ADFP#V1 include a CAN controller, and which version is supported?

Yes, the R5F72165ADFP#V1 integrates three independent CAN controllers compliant with ISO 11898-1:2003 (CAN 2.0B). Each controller supports both standard (11-bit) and extended (29-bit) identifier formats, configurable bit rates up to 1 Mbps, and hardware message filtering. This is documented in Section 1.1 "Features" and Section 13 "CAN Controller" of the SH7214/SH7216 Hardware User's Manual. The R5F72165ADFP#V1 uses these controllers for robust fieldbus communication in industrial networks.

What type of ADC is integrated into the R5F72165ADFP#V1, and how many channels does it have?

The R5F72165ADFP#V1 includes a 12-channel, 10-bit successive-approximation (SAR) ADC with a typical conversion time of 1.2 μs. It supports hardware-triggered sampling from multiple sources (e.g., MTU2S timers, SCI, or software), scan mode for sequential channel conversion, and selectable reference voltage (AVCC or internal 2.5 V). These specifications are verified in Section 12 "A/D Converter" of the SH7214/SH7216 Hardware User's Manual. The ADC is used in the R5F72165ADFP#V1 for precision analog sensing in motor current feedback and temperature monitoring.

Is the R5F72165ADFP#V1 pin-compatible with other members of the SH7216 Series?

Yes, the R5F72165ADFP#V1 shares the same 144-pin LQFP package and pin assignment with other SH7216 Series devices such as R5F72164ADFP#V1 and R5F72166ADFP#V1. Pin compatibility is explicitly confirmed in Section 1.3 "Pin Assignment" and Section 1.4 "Pin Functions" of the SH7214/SH7216 Hardware User's Manual (Rev. 4.00). This allows board-level reuse across variants when selecting the R5F72165ADFP#V1 for CAN-enabled designs.

What debug interface does the R5F72165ADFP#V1 support, and is JTAG available?

The R5F72165ADFP#V1 supports IEEE 1149.1-compliant JTAG for boundary-scan testing and on-chip debugging, including real-time trace, breakpoints, and register visibility. JTAG functionality is implemented via dedicated pins TDI, TDO, TMS, TCK, and TRST, as defined in Section 1.4 "Pin Functions" and Section 20 "On-Chip Debug Support" of the SH7214/SH7216 Hardware User's Manual. This JTAG interface enables full visibility into the R5F72165ADFP#V1 during development and production test phases.
