FAQ

What is the maximum operating frequency of the DS72611RP100FPV?

The DS72611RP100FPV operates at a maximum system clock frequency of 100 MHz, achieved via its on-chip Clock Pulse Generator (CPG) with PLL. This frequency is sustained across the full −40°C to +85°C industrial temperature range when supplied with 3.3 V ±5%. The DS72611RP100FPV's SH-2A core delivers consistent dual-issue instruction throughput at this speed, enabling sub-microsecond interrupt response critical for motor control timing.

Does the DS72611RP100FPV include an integrated USB transceiver?

Yes, the DS72611RP100FPV includes a full-speed USB 2.0 device transceiver with integrated termination resistors and differential line drivers. This allows direct connection to a USB connector without external PHY components. The DS72611RP100FPV supports USB HID and CDC device classes out of the box, and its USB module is clocked independently via the CPG, ensuring reliable enumeration even during dynamic CPU frequency scaling.

What type of floating-point unit does the DS72611RP100FPV feature?

The DS72611RP100FPV features a hardware Floating-Point Unit (FPU) compliant with IEEE 754 standards for both single- and double-precision arithmetic. It executes FPU instructions in parallel with integer operations, reducing typical FOC inner-loop computation time to under 1.2 µs. The DS72611RP100FPV's FPU includes dedicated registers (FR0–FR15), FPSCR status/control, and FPUL communication register - all accessible via standard SH-2A instruction mnemonics.

Is the DS72611RP100FPV qualified for industrial temperature operation?

Yes, the DS72611RP100FPV is rated for industrial temperature operation from −40°C to +85°C and is supplied at 3.0–3.6 V. Its electrical characteristics - including ADC accuracy, timer jitter, and Flash write endurance - are fully specified across this range. The DS72611RP100FPV's LQFP-144 package includes an exposed thermal pad to enhance heat dissipation, supporting continuous 1.5 W power dissipation in ambient air without forced convection.

How many CAN channels does the DS72611RP100FPV support?

The DS72611RP100FPV integrates one CAN 2.0B-compliant controller supporting both standard (11-bit) and extended (29-bit) identifier frames, with programmable bit rates up to 1 Mbps. It provides two dedicated message buffers with FIFO mode and automatic retransmission. While it does not include multiple independent CAN controllers, the DS72611RP100FPV's single CAN module is sufficient for most industrial drive and automation node applications requiring peer-to-peer or master-slave topology.
