FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The XE164F96F66LACFXQMA1 operates at a maximum CPU clock frequency of 80 MHz, achieving a 12.5 ns instruction cycle time. This is enabled by its five-stage pipeline and zero-cycle jump execution, allowing single-cycle execution of most instructions including 16×16 multiply and 32-bit addition with 40-bit result - essential for tight control loops in motor and power applications.

Does this device support hardware-based PWM dead-time insertion?

Yes, the CCU6x capture/compare units provide dedicated hardware dead-time insertion with programmable delay (1–1023 CPU cycles) and automatic fault shutdown. Each CCU6x unit supports complementary PWM output pairs with independent dead-time control, enabling safe IGBT/MOSFET gate driving in half-bridge and three-phase inverter topologies without software overhead.

How many CAN message objects does the MultiCAN module support?

The MultiCAN module supports up to 128 configurable message objects across its four CAN nodes. Each object includes dedicated acceptance filtering, transmission priority, and data length control. Message RAM is organized in 16-byte blocks, and hardware arbitration ensures deterministic transmission scheduling even under heavy bus load - critical for automotive and industrial real-time networks.

Is there on-chip debug support, and what interface is used?

Yes, the device includes full On-Chip Debug Support (OCDS) compliant with IEEE 1149.1, accessible via a 4-pin JTAG interface (TCK, TMS, TDI, TDO). OCDS supports real-time breakpoints, watchpoints, register inspection, flash programming, and boundary scan testing - enabling complete development and validation without requiring external emulators or intrusive probes.
