Product details
Overview
XC226756F66LACKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU with five-stage pipeline, 448 KB on-chip Flash memory, 16 KB DSRAM, and dual 10-bit A/D converters (11 + 5 channels). It integrates MultiCAN (Rev. 2.0B, up to 5 nodes), six serial interface channels (UART/LIN/SPI/IIC/IIS), and CCU6x PWM units. It targets automotive powertrain and chassis control systems requiring deterministic real-time response and CAN-based networking.
For engineers reviewing the XC226756F66LACKXUMA1 datasheet, XC226756F66LACKXUMA1 pinout, XC226756F66LACKXUMA1 application, or XC226756F66LACKXUMA1 equivalent, key selection criteria include Flash size (448 KB), operating temperature range (–40 °C to 125 °C), CAN node count (5), ADC channel configuration (ADC0: 11 ch, ADC1: 5 ch), and LQFP-100 package compatibility with automotive-grade thermal and EMI requirements.
Technical Context
The XC226756F66LACKXUMA1 implements a C166-compatible register-based CPU core with zero-cycle jumps, one-cycle 32-bit arithmetic, and MAC instructions-enabling deterministic execution for motor control loops. Its interrupt system supports 87 sources across 16 priority levels, with sample-rate capability down to 12.5 ns for time-critical sensor sampling.
Peripheral integration includes two synchronizable A/D converters with sub-1 µs conversion time and optional data preprocessing, four CCU6x modules for independent PWM generation with dead-time control, and a MultiCAN module supporting full CAN message objects (128 total) and gateway functionality across five physical CAN nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC2267-72F66LACKXUMA1 | 576 KB Flash, 32 KB PSRAM, same package/temp grade - higher code storage but reduced SRAM for data buffers. | Suitable for applications requiring larger diagnostic stacks or OTA update partitions but less real-time data logging. | Select when firmware complexity exceeds 448 KB but real-time buffer demands remain moderate. |
| SAK-XC2264-56F66LACKXUMA1 | 448 KB Flash, 2 CAN nodes, 4 serial channels, CCU6x limited to 2 modules - lower peripheral count and reduced networking capacity. | Targeted at cost-sensitive chassis modules (e.g., seat control) where 5-node CAN and 6 serial interfaces are unnecessary. | Choose for non-gateway roles with simplified communication requirements and lower BOM cost target. |
Compared with SAK-XC2267-72F66LACKXUMA1, this part trades PSRAM capacity for tighter memory footprint; versus SAK-XC2264-56F66LACKXUMA1, it delivers full 5-node CAN and expanded CCU6x resources essential for powertrain gateway and motor control consolidation.

FAQ
What is the maximum operating frequency and associated instruction cycle time?
The XC226756F66LACKXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time. This is achieved using the on-chip PLL with external crystal input (4–20 MHz). All integer arithmetic instructions-including 32-bit addition, subtraction, and 16×16 multiplication-execute in a single cycle, enabling deterministic timing for motor control and engine management loops.
Does this microcontroller support AEC-Q100 qualification and what grade applies?
Yes, the XC226756F66LACKXUMA1 is qualified per AEC-Q100 Grade 1, covering operation from –40 °C to +125 °C ambient temperature. This qualification includes stress testing for HTOL, TC, UHST, and ESD per automotive reliability standards. The device is intended for under-hood applications such as engine control and transmission modules where thermal robustness and long-term stability are mandatory.
How many CAN nodes and message objects does the MultiCAN module support?
The MultiCAN module supports up to 5 physical CAN nodes with a total of 128 configurable message objects. Each node can be independently configured for Full CAN or Basic CAN operation, and hardware-based message filtering and FIFO buffering are implemented per node. This architecture enables gateway functionality-routing messages between different CAN domains without CPU intervention-critical for modern vehicle network topologies.
What debug and programming interfaces are available on-chip?
The device provides JTAG (IEEE 1149.1) for boundary scan, flash programming, and real-time on-chip debugging via OCDS (On-Chip Debug Support). It also includes a boot ROM with UART-based bootloader for field firmware updates without debugger hardware. No SWD or proprietary debug interfaces are supported-the JTAG port is the sole standardized debug access point defined in the datasheet.
