FAQ

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

The XE164F24F66LACFXUMA1 operates at a maximum CPU clock of 80 MHz, delivering a 12.5 ns instruction cycle for single-cycle execution of arithmetic, logical, and MAC operations. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40 °C to +85 °C) conditions per the V2.1 datasheet.

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

Yes - all three integrated CCU6 modules provide configurable hardware dead-time insertion with resolution down to one CPU clock cycle (12.5 ns at 80 MHz). Each CCU6 unit supports independent dead-time registers, automatic shadow transfer, and fault-induced forced output states for inverter protection.

How many analog input channels does the ADC subsystem support?

The device integrates two synchronizable 10-bit ADCs supporting a total of 16 channels: 11 dedicated analog inputs plus 5 additional channels shared with port pins. Channel selection, sampling sequence, and trigger sources are fully programmable via dedicated ADC control registers.

Is JTAG debug support available, and what capabilities does it include?

Yes - on-chip debug support (OCDS) is implemented via IEEE 1149.1-compliant JTAG interface. It enables real-time program execution control, hardware breakpoints, memory/register read/write, trace buffer capture, and non-intrusive interrupt latency measurement - all without halting peripheral operation.
