FAQ

What is the maximum operating frequency of the XMC1301T038F0008AAXUMA1?

The XMC1301T038F0008AAXUMA1 operates at up to 48 MHz under specified industrial conditions (–40°C to +125°C, 3.3 V ±5 %). This frequency is supported by the internal PLL and validated across all speed grades in the AB-step silicon revision, enabling sub-microsecond interrupt latency for time-critical control tasks such as PWM update and fault response.

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

Yes - the CCU4 and CCU8 timer units integrate configurable dead-time generators with resolution down to 1 ns (at 48 MHz). These operate independently of CPU intervention and support automatic fault shutdown via BCCU linkage, ensuring safe 6-channel gate driving for 3-phase inverters without software overhead or jitter.

Can the VADC perform simultaneous sampling across multiple channels?

Yes - the VADC supports hardware-synchronized sampling of up to 4 channels per conversion group using the ERU or CCU4 trigger sources. This enables true simultaneous acquisition of motor phase currents and DC-link voltage, critical for accurate Clarke transform and torque estimation in FOC implementations.

Is there a factory-programmed unique ID or serial number?

Yes - each XMC1301T038F0008AAXUMA1 contains a 96-bit unique device identifier stored in the SFR memory map at address 0x00F00000. This value is laser-trimmed during wafer test and remains immutable across flash erases, enabling secure device authentication and traceability in production firmware.
