FAQ
What is the maximum CPU clock frequency supported by XC164CS32F20FBBAKXUMA1?
The device operates at a maximum CPU clock frequency of 40 MHz, achieved via an internal PLL that multiplies a 1–20 MHz external crystal input. At this speed, instruction execution takes 25 ns per cycle, and 16×16-bit multiplication completes in one cycle - critical for fast motor control loop calculations.
Does XC164CS32F20FBBAKXUMA1 support JTAG-based debugging?
Yes, it includes full IEEE 1149.1-compliant JTAG support via dedicated TCK/TDI/TDO/TMS pins (Pins 100, 98, 97, 96), enabling boundary scan testing and on-chip debug via Infineon's OCDS protocol - essential for validating timing-critical motor control firmware during development.
What is the role of the CAPCOM6E module in this microcontroller?
The CAPCOM6E module provides two independent 16-bit timers optimized for motor control PWM generation, supporting complementary outputs with programmable dead-time insertion, center-aligned modes, and automatic fault shutdown - directly enabling safe, high-efficiency 3-phase inverter drive without external logic.
Is XC164CS32F20FBBAKXUMA1 qualified for automotive under-hood use?
Yes, it is rated for -40°C to +125°C operation and qualified per AEC-Q100 Grade 0 requirements. Its 2.5 V core supply, 5 V I/O tolerance, built-in oscillator watchdog, and EMC-optimized gated clock architecture make it suitable for engine compartment applications including EPS and headlamp control.
