FAQ

What is the maximum operating frequency of the DF2117VBG20IHV?

The DF2117VBG20IHV supports a maximum CPU clock frequency of 25 MHz. This is achieved using the on-chip PLL with an external crystal (1–20 MHz) or clock source. At 25 MHz, the instruction execution time for most 16-bit instructions is 40 ns, enabling tight real-time loop control in motor drive applications. The DF2117VBG20IHV maintains full functionality across its specified voltage range (3.0–3.6 V) at this speed.

Does the DF2117VBG20IHV support IEBus communication natively?

Yes, the DF2117VBG20IHV includes hardware-level IEBus support through its SCI0 channel, compliant with IEBus Rev. 2.0 specifications. This enables direct connection to IEBus transceivers (e.g., R2A25105SP) without software bit-banging, reducing CPU overhead and ensuring accurate timing for arbitration, collision detection, and frame formatting. The DF2117VBG20IHV's dedicated IEBus mode configures SCI0 for 38.4 kbps operation with automatic CRC generation and error flagging.

What PWM features does the DF2117VBG20IHV provide for motor control?

The DF2117VBG20IHV integrates two 16-bit TPU modules (TPU_A and TPU_B), delivering up to 16 independent PWM channels with complementary output pairs, programmable dead-time insertion (0–1023 × f_CLK), and center-aligned or edge-aligned modes. Each channel supports 16-bit resolution and synchronous update, allowing precise duty-cycle control for 3-phase inverter gate drivers. The DF2117VBG20IHV also provides hardware fault protection via external shutdown inputs that force PWM outputs to safe state within 200 ns.

Is there on-chip debug capability for the DF2117VBG20IHV?

Yes, the DF2117VBG20IHV supports FULL-DEBUG mode via a single-wire SWD (Serial Wire Debug) interface. This enables non-intrusive real-time debugging, including instruction stepping, breakpoint setting, register and memory inspection, and trace buffer capture - all without halting CPU execution. The DF2117VBG20IHV's debug module is accessible through standard Renesas E2 emulator hardware and compatible with CS+ and e2 studio IDEs.

What is the ADC specification of the DF2117VBG20IHV?

The DF2117VBG20IHV features a 12-bit successive-approximation A/D converter with 8 analog input channels, 1.25 µs conversion time, and ±1 LSB integral nonlinearity. It supports software-triggered and timer-triggered conversions, selectable reference voltages (AVCC or internal 2.5 V), and built-in sample-and-hold circuitry. The DF2117VBG20IHV's ADC is optimized for industrial signal acquisition, offering noise suppression modes and automatic channel scanning for multi-sensor monitoring.
