FAQ
What is the maximum operating frequency of the SAF-XC164CS-32F20F BB-A?
The SAF-XC164CS-32F20F BB-A operates at a maximum CPU clock frequency of 20 MHz, derived from an internal PLL that multiplies the external crystal or oscillator input. This frequency is fully supported across the full industrial temperature range (-40°C to +125°C) and enables deterministic interrupt latency of ≤1.5 µs for critical control tasks.
Does this MCU support CAN FD or only classical CAN?
The SAF-XC164CS-32F20F BB-A integrates a classical CAN 2.0B controller compliant with ISO 11898-1, supporting data rates up to 1 Mbps. It does not support CAN FD features such as flexible data-rate or extended data length; CAN FD capability requires newer families like the XMC4000 or AURIX TC2xx series.
Is there a built-in bootloader, and how is firmware updated?
Yes, the device includes an 8 KB ROM-resident boot loader supporting UART-based firmware updates via ASC0. The dual-bank Flash architecture allows in-application programming (IAP), enabling safe field updates by executing from one bank while writing to the other-no external programmer is required for routine revisions.
What debug interface is supported for development?
The SAF-XC164CS-32F20F BB-A supports Infineon's DAS (Debug Access Service) interface via JTAG, compatible with the DAS512 and DAS524 debug adapters. It provides full hardware breakpoint support, real-time variable watch, and flash programming through Infineon's DAVE™ IDE and third-party tools like Lauterbach TRACE32.
