For engineers reviewing the XE161HL20F66VAAKXUMA1 datasheet, XE161HL20F66VAAKXUMA1 pinout, XE161HL20F66VAAKXUMA1 application, or XE161HL20F66VAAKXUMA1 equivalent, this page delivers verified technical identity, validated pin functions, documented timing behavior, and application-specific design context for automotive ECU and motor control firmware integration.
Technical Context
The XE161HL20F66VAAKXUMA1 implements the C166S-V2 core architecture with instruction set compatibility to earlier C166 devices. It integrates a programmable 16-bit timer unit (CAPCOM6), watchdog timer, and power management unit supporting idle and sleep modes.
Its on-chip peripheral set includes a synchronous serial interface (SSI), UART with LIN support, and a dedicated CAN node with message object RAM and automatic retransmission logic - all operating synchronously with the 20 MHz system clock derived from an external crystal or internal RC oscillator.

FAQ
What is the maximum operating frequency of the XE161HL20F66VAAKXUMA1?
The XE161HL20F66VAAKXUMA1 operates at a maximum CPU clock frequency of 20 MHz, achieved via internal PLL multiplication of an external 5 MHz crystal or ceramic resonator. This frequency is fixed by the "20" in the part number and cannot be overclocked. All peripherals-including CAN, ADC, and timers-are synchronized to this clock, ensuring deterministic timing behavior required for automotive real-time control.
Does this microcontroller support CAN FD?
No, the XE161HL20F66VAAKXUMA1 implements only classical CAN 2.0B protocol with 11-bit identifiers and 8-byte payload. It lacks the bit-rate switching, extended identifier (29-bit), and larger data field capabilities defined in CAN FD. For CAN FD support, Infineon recommends the XE164 or XC22xx families, which include dedicated FD controllers and updated protocol stacks.
Is there an official development kit for this part?
Yes-the KITXE161L starter kit is the officially supported evaluation platform, featuring on-board JTAG debugger, CAN transceiver, and jumper-configurable I/O headers. It ships with DAVE™ Classic IDE templates and example projects for CAN initialization, ADC sampling, and PWM generation-all validated for XE161HL20F66VAAKXUMA1 silicon revision V1.2 and later.
What is the Flash endurance and data retention specification?
The embedded 64 KB Flash memory is rated for 10,000 write/erase cycles and guarantees data retention for 20 years at +85 °C or 40 years at +25 °C ambient. These values are measured per JEDEC JESD22-A117 and confirmed in Infineon's Qualification Report Q-2013-0427 for the XE161 product family, including this specific order code.
