FAQ
What is the maximum CPU clock frequency supported by XC164CS16F20FBBKXUMA1?
The device supports a maximum CPU clock frequency of 40 MHz, achieved via internal PLL multiplication from an external crystal (1–20 MHz). At this frequency, instruction execution time is 25 ns, and 16×16-bit multiplication completes in one cycle. The datasheet specifies 40 MHz as the absolute maximum rated frequency under all operating conditions.
Does XC164CS16F20FBBKXUMA1 include hardware error correction for Flash memory?
Yes, the 64 KB on-chip eFlash includes built-in Error Correction Code (ECC) logic that detects and corrects single-bit errors and detects double-bit errors in real time. This feature is enabled by default at power-on and complies with automotive functional safety requirements for non-volatile memory integrity.
Can the TwinCAN module operate in gateway mode without CPU intervention?
Yes, the TwinCAN module supports autonomous hardware gateway functionality: messages can be routed between CAN-A and CAN-B nodes using configurable acceptance filters and transfer objects, with no CPU involvement. This offloads protocol translation tasks and reduces latency in multi-bus vehicle networks.
Is JTAG debug support available on XC164CS16F20FBBKXUMA1, and what pins are used?
Yes, full on-chip debug support is provided via IEEE 1149.1 JTAG interface using five dedicated pins: TRST (Pin 7), TCK (Pin 8), TMS (Pin 9), TDI (Pin 10), and TDO (Pin 11). This enables real-time breakpointing, register inspection, and flash programming through standard tools like DAS and Lauterbach TRACE32.
