FAQ
Is SAF-XC164CS-16F20F BB pin-compatible with other XC164 variants?
No. SAF-XC164CS-16F20F BB uses a 64-pin LQFP package with specific pin assignments for CAN, ADC, and memory interface. Pinouts differ from XC164S and XC164CM variants due to differing peripheral sets and signal multiplexing-migration requires PCB redesign and firmware adaptation.
Does this MCU support bootloading over CAN?
Yes. The SAF-XC164CS-16F20F BB includes a ROM-based bootloader accessible via CAN using standardized UDS services (0x31, 0x34, 0x36, 0x37). Bootloader activation requires specific CAN ID sequence and checksum validation per Infineon Application Note AP20012.
What is the maximum operating frequency of the internal oscillator?
The SAF-XC164CS-16F20F BB does not include an internal RC oscillator. It requires an external crystal (1–20 MHz) or clock source connected to XTAL1/XTAL2. System clock is derived directly from this source or multiplied via PLL (if enabled in configuration registers).
Can the on-chip Flash be programmed in-circuit?
Yes. In-system programming (ISP) is supported via JTAG or CAN using Infineon's DAS software tools. Flash sectors can be erased and rewritten while the device remains soldered on the target board, enabling field firmware updates without removing the MCU.
