Product details
Overview
XC226796F66LACKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU with five-stage pipeline, 768 KB on-chip Flash, 64 KB PSRAM, dual 10-bit ADCs (11+5 channels), MultiCAN Rev. 2.0B interface with 5 nodes, and CCU6x PWM units. It operates from 3.0 V to 5.5 V across –40 °C to 125 °C and targets automotive powertrain and chassis control systems requiring deterministic real-time response.
For engineers reviewing the XC226796F66LACKXUMA1 datasheet, XC226796F66LACKXUMA1 pinout, XC226796F66LACKXUMA1 application, or XC226796F66LACKXUMA1 equivalent, key selection criteria include CAN node count (5), ADC channel configuration (ADC0: 11 ch, ADC1: 5 ch), Flash/PSRAM sizing (768 KB / 64 KB), CCU6 module count (4), and industrial-temperature grade operation.
Technical Context
The XC226796F66LACKXUMA1 implements a C166-compatible register-based CPU core with zero-cycle jumps, one-cycle MAC, and fast context switching via two local register banks. Its memory subsystem includes 1 KB SBRAM, 2 KB DPRAM, 16 KB DSRAM, and up to 768 KB Flash - all mapped within a unified 16 MB linear address space.
Peripheral integration centers on deterministic timing: dual A/D converters achieve sub-1 µs conversion with data preprocessing; MultiCAN supports 128 message objects with gateway functionality; CCU6x units deliver flexible PWM generation with dead-time insertion and synchronization; and the GPT12E timer provides five independent channels for capture, compare, and counting tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC2267-96F66L | Same die, identical Flash/PSRAM/ADC/CAN specs; differs only in marking and packaging variant (no "XUMA1" suffix). | No functional difference - used interchangeably in production where traceability or tape-and-reel format differs. | Select when standard reel packaging or non-"XUMA1" top-marking is required for legacy BOM alignment. |
| SAK-XC2264-96F66L | Same 768 KB Flash and 64 KB PSRAM, but only 2 CAN nodes, 8 ADC channels (ADC0 only), and 2 CCU6 modules. | Suitable for lower-complexity chassis modules (e.g., seat control, lighting) where 5-CAN and full ADC count are unnecessary. | Choose for cost-optimized designs with reduced peripheral demand and no need for multi-domain CAN gateway functionality. |
Compared with SAK-XC2267-96F66L, XC226796F66LACKXUMA1 offers identical functionality but with enhanced traceability and logistics handling; versus SAK-XC2264-96F66L, it delivers 2.5× more CAN nodes and 2× more ADC channels - enabling consolidation of multiple ECUs into a single high-integration controller.

FAQ
What is the maximum operating frequency and associated instruction cycle time?
The XC226796F66LACKXUMA1 achieves a maximum CPU clock of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of arithmetic, logical, and MAC operations. This timing is guaranteed across the full –40 °C to +125 °C temperature range and 3.0 V to 5.5 V supply voltage, verified per Infineon's DC and AC parameter specifications in Section 4 of the datasheet.
Does this microcontroller support AUTOSAR-compliant software architecture?
Yes - the XC226796F66LACKXUMA1 provides the hardware foundation for AUTOSAR Classic Platform implementation, including memory protection unit (MPU) support via its MMU-like address translation, deterministic interrupt latency (<1 µs worst-case), MultiCAN with message object filtering, and standardized debug interfaces (JTAG/OCDS) required for ECU calibration and diagnostics.
How many CAN nodes and message objects does the MultiCAN module support?
The MultiCAN module in XC226796F66LACKXUMA1 supports up to 5 independent CAN nodes (CAN0–CAN4) and manages up to 128 message objects with full CAN/Basic CAN capability per node. Each node operates independently with configurable bit rates, acceptance filters, and transmit/receive FIFOs - confirmed in Section 3.12 and Table 1 of the datasheet.
Is there on-chip debug support, and what interface is used?
Yes - the device integrates On-Chip Debug Support (OCDS) accessible via a standard 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST). OCDS enables full real-time debugging, breakpoint setting, memory/register access, and trace capabilities without halting CPU execution, as detailed in Section 3.5 and Figure 2-1 of the datasheet.
