Product details
Overview
XC2268M72F66LAAFXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Base Line family, featuring an 80 MHz C166-compatible CPU with five-stage pipeline, 832 KB on-chip Flash, 16 KB DSRAM, and integrated MultiCAN (Rev. 2.0B) supporting up to 6 nodes. It delivers 32-bit performance in automotive powertrain control and industrial motor drive applications.
For engineers reviewing the XC2268M72F66LAAFXUMA1 datasheet, XC2268M72F66LAAFXUMA1 pinout, XC2268M72F66LAAFXUMA1 application, or XC2268M72F66LAAFXUMA1 equivalent, key selection considerations include its 100-pin LQFP package, 3.0–5.5 V single-supply operation, 16-channel ADC with <1 µs conversion time, CCU6x PWM units for motor control, and JTAG/DAP debug interface compliance.
Technical Context
The XC2268M72F66LAAFXUMA1 implements a C166-derived CPU core with zero-cycle jumps, one-cycle 32-bit arithmetic, and background 32/16-bit division in 21 cycles. Its memory subsystem includes ECC-protected Flash, MPU-enforced memory protection, and 24-bit PEC pointers spanning the full 16 MB linear address space.
Peripheral integration centers on deterministic real-time control: dual 16-channel ADCs with broken-wire detection, six CAN nodes with 256 message objects, four CCU6x units for independent PWM generation, and a programmable watchdog with oscillator monitoring - all synchronized via a centralized system timer and wake-up clock architecture.

FAQ
What debug interfaces does XC2268M72F66LAAFXUMA1 support?
XC2268M72F66LAAFXUMA1 supports both JTAG and Infineon's Device Access Port (DAP) for on-chip debug. The JTAG interface complies with IEEE 1149.1 and enables full boundary-scan, flash programming, and real-time variable inspection. DAP provides additional low-level access to debug registers and memory-mapped peripherals, used by Infineon's DAS and iSYSTEM tools.
Does this MCU support CAN FD?
No. XC2268M72F66LAAFXUMA1 implements MultiCAN Rev. 2.0B only, supporting Classical CAN (ISO 11898-1:2003) with bit rates up to 1 Mbit/s and message objects compliant with Full CAN and Basic CAN. It lacks CAN FD framing, data rate switching, and extended payload support introduced in later TriCore generations.
What is the maximum operating temperature range?
XC2268M72F66LAAFXUMA1 is qualified for industrial and automotive applications with an ambient operating temperature range of –40 °C to +125 °C. This rating is validated per AEC-Q100 Grade 1 requirements and applies to the full 100-pin LQFP package under specified voltage and thermal derating conditions.
How is Flash memory protected against corruption?
Flash memory uses Error Correction Code (ECC) with single-bit error correction and double-bit error detection. Each 64-bit word includes 8 bits of ECC, enforced automatically during read/write cycles. Additionally, the Memory Protection Unit (MPU) prevents unauthorized write access to Flash sectors, and the hardware CRC checker validates Flash contents at boot and on-demand.
