Overview

XC2734X40F80LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring an 80 MHz CPU clock (12.5 ns instruction cycle), 320 KB on-chip Flash memory, 16 KB PSRAM, and dual CAN 2.0B interfaces with 64 message objects across two nodes. It integrates CCU6x PWM units, two 10-bit ADCs (sub-1 μs conversion), and operates from 3.0 V to 5.5 V for automotive body control modules.

For engineers reviewing the XC2734X40F80LAAKXUMA1 datasheet, XC2734X40F80LAAKXUMA1 pinout, XC2734X40F80LAAKXUMA1 application, or XC2734X40F80LAAKXUMA1 equivalent, key selection criteria include its 80 MHz TriCore-compatible CPU performance, dual-CAN gateway capability, ECC-protected Flash, and LQFP-64 Green package with -40°C to 125°C extended temperature rating.

Technical Context

The XC2734X40F80LAAKXUMA1 implements a five-stage pipelined C166-compatible CPU core with MPU, supporting single-cycle 32-bit arithmetic and MAC operations. Its memory subsystem includes 320 KB Flash with ECC, 16 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 8 KB SBRAM - all mapped within a unified 16 MB linear address space.

Peripheral integration centers on real-time control: two synchronizable 10-bit ADCs (9 channels total, broken-wire detection), CCU6x units for high-resolution PWM generation, MultiCAN Rev. 2.0B with gateway logic, and USIC modules configurable as UART/LIN/SPI/I²C/I²S. Clocking uses an on-chip PLL with selectable external or internal sources.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The XC2734X40F80LAAKXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of most instructions. This timing is validated under specified supply (3.0–5.5 V) and temperature (-40°C to +125°C) conditions per Data Sheet V1.5 Section 4.7.2.1.

Does this microcontroller support hardware-based memory protection?

Yes, it integrates a Memory Protection Unit (MPU) that enforces privilege levels and region-based access control for code and data memory. The MPU supports up to eight protected memory regions with configurable size, attributes, and access permissions - essential for partitioning safety-critical and non-safety software tasks.

How many CAN nodes does the XC2734X40F80LAAKXUMA1 support, and what protocol versions are implemented?

The device integrates a MultiCAN module supporting two independent CAN 2.0B-compliant nodes (Rev. 2.0B active), each with full CAN and Basic CAN message object support. It provides 64 total message objects, configurable for transmission, reception, or filtering, and includes gateway functionality for cross-node message forwarding.

Is there on-chip debug support, and which interfaces are available?

Yes, on-chip debug support is provided via both JTAG (IEEE 1149.1) and Infineon's Device Access Port (DAP). These interfaces enable full boundary-scan testing, flash programming, real-time variable observation, and non-intrusive breakpoint setting - supported by DAVE™ and third-party tools like Lauterbach TRACE32.
