Product details
Overview
XC2765X104F80LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Base Line family, featuring an 80 MHz CPU clock (12.5 ns instruction cycle), 832 KB on-chip Flash memory, and dual 10-bit ADCs with ≤1 μs conversion time. It integrates MultiCAN Rev. 2.0B (2 nodes, 128 message objects), CCU6x PWM units, and operates from a single 3.0–5.5 V supply. Used in automotive engine control units for real-time sensor acquisition and actuator drive.
For engineers reviewing the XC2765X104F80LAAKXUMA1 datasheet, XC2765X104F80LAAKXUMA1 pinout, XC2765X104F80LAAKXUMA1 application, or XC2765X104F80LAAKXUMA1 equivalent, key selection criteria include CAN node count, Flash endurance (100k write/erase cycles), SBRAM retention during standby, PEC-driven DMA latency, and ECC-protected SRAM/Flash integrity verification.
Technical Context
The XC2765X104F80LAAKXUMA1 implements a C166-compatible 5-stage pipelined CPU with MPU, supporting 16 MB linear address space and fast context switching via dual local register banks. Its interrupt system handles up to 96 sources across 16 priority levels, with sample-rate capability down to 12.5 ns.
Peripheral integration includes two synchronizable 10-bit ADCs (16 total channels, broken-wire detection), six USIC modules configurable as UART/LIN/SPI/I²C/IIS, and a hardware CRC checker with programmable polynomial for memory area supervision. The MultiCAN module supports full CAN and Basic CAN modes with gateway functionality across two physical nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 80 MHz - enables 12.5 ns instruction cycle for deterministic real-time execution in engine timing-critical tasks |
| Flash Memory | 832 KB - sufficient for complex automotive firmware with bootloader, application, and calibration data partitions |
| ADC Resolution & Speed | 10-bit, ≤1 μs conversion - meets ISO 16750-2 transient immunity requirements for analog sensor sampling in ECU environments |
| CAN Nodes | 2 independent CAN 2.0B interfaces - supports powertrain and chassis domain communication without external bridge IC |
| Supply Voltage | 3.0–5.5 V - compatible with automotive battery voltage range including cold-crank (6 V) and load-dump (40 V) transients via external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2785X104F80LAAKXUMA1 | Same XC2000 Base Line architecture but with 128 KB additional Flash (960 KB total) and extended temperature grade (−40°C to +125°C) | Required for Tier-1 suppliers specifying extended junction temperature margin in under-hood EPS or turbocharger control | Select when >832 KB Flash is needed for dual-application firmware or when operating ambient exceeds +105°C |
| TC1767-128F133HRBAKXUMA1 | TriCore™ 32-bit CPU (not C166-compatible), 133 MHz, 1.5 MB Flash, integrated Ethernet MAC, no on-chip SBRAM | Targets next-gen ADAS domain controllers requiring TCP/IP stack and higher compute throughput, not drop-in replacement | Choose only for new designs needing Ethernet connectivity and >100 DMIPS; requires full toolchain and software migration |
Compared with XC2765X104F80LAAKXUMA1, the XC2785X variant extends Flash capacity and thermal rating for future-proofing, while the TC1767 shifts to TriCore architecture with Ethernet support-neither offers pin or code compatibility, making them architectural alternatives rather than direct substitutes.

FAQ
What is the maximum operating temperature for XC2765X104F80LAAKXUMA1?
The device is qualified per AEC-Q100 Grade 2, with guaranteed operation from −40°C to +105°C ambient temperature. Junction temperature must not exceed +125°C under steady-state conditions, as validated by thermal resistance (RθJA = 32°C/W) and board-level thermal design per Infineon Application Note AP32077.
Does XC2765X104F80LAAKXUMA1 support JTAG debugging in production mode?
Yes-JTAG interface remains fully functional in production devices via the Device Access Port (DAP), supporting boundary-scan testing, flash programming, and real-time trace with Infineon DAS-2 debug adapter. Security lock bits can disable debug access post-programming per customer-defined policy.
How many CAN message objects are supported simultaneously?
The integrated MultiCAN module supports up to 128 message objects distributed across two CAN nodes. Each node allocates message objects dynamically via dedicated RAM buffers, enabling concurrent handling of standard (11-bit) and extended (29-bit) identifiers with hardware acceptance filtering.
Is the on-chip Flash memory field-programmable via CAN or UART?
Yes-the on-chip bootloader supports in-system programming (ISP) via CAN 2.0B or UART using standardized UDS (ISO 14229-1) diagnostic services. Firmware updates require authentication keys stored in protected OTP memory and CRC-verified packet transfer to prevent unauthorized modification.
