FAQ
What is the maximum operating frequency of the SAF-XC167CI-32F20F CPU core?
The SAF-XC167CI-32F20F operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time. This speed is achievable with appropriate Flash wait-state configuration (via WSFLASH bits in IMBCTRL) and external clock source stability. The C166SV2 core's 5-stage pipeline and zero-cycle jump execution ensure deterministic timing at this rate.
Does the SAF-XC167CI-32F20F support in-application programming (IAP) of its on-chip Flash memory?
Yes - the device supports in-system programming (ISP) and in-application programming (IAP) of its 256 KB Flash via the on-chip bootstrap loader, accessible through ASC0 or CAN0 interfaces. Firmware updates can be performed without external programming hardware, provided the application reserves protected sectors for loader code and validates checksums before committing writes.
How many CAN controllers does the SAF-XC167CI-32F20F integrate, and what protocol versions do they support?
The SAF-XC167CI-32F20F integrates two independent CAN controllers (CAN0 and CAN1) forming the TwinCAN module, compliant with CAN Specification Version 2.0B (active). Each supports both Full CAN and Basic CAN modes, with 32 shared message objects and hardware gateway functionality for message routing between nodes without CPU involvement.
Is the SAF-XC167CI-32F20F pin-compatible with other XC167 derivatives such as the SAK-XC167CI-32F40F?
Yes - SAF-XC167CI-32F20F and SAK-XC167CI-32F40F share identical 144-pin TQFP packaging, pinout definition, and electrical characteristics. The only functional difference is the extended temperature rating (-40 °C to +125 °C) of the SAK variant; all registers, memory maps, and peripheral configurations remain binary-compatible.
