Infineon Technologies XE167FM72F80LRABKXUMA1

Overview

XE167FM72F80LRABKXUMA1 from Infineon Technologies is a 16-bit real-time signal controller with C166™ architecture, integrated MultiCAN interface (Rev. 2.0B), dual 10-bit ADCs (24 channels, <1 µs conversion), and 576 KB on-chip Flash memory. It operates at 80 MHz CPU clock (12.5 ns instruction cycle), supports single-cycle MAC, and targets motor control and industrial automation systems requiring deterministic timing and CAN-based communication.

For engineers reviewing the XE167FM72F80LRABKXUMA1 datasheet, XE167FM72F80LRABKXUMA1 pinout, XE167FM72F80LRABKXUMA1 application, or XE167FM72F80LRABKXUMA1 equivalent, key selection criteria include its 144-pin LQFP package, 3.0–5.5 V supply range, integrated CCU6x PWM units, hardware CRC checker, and MPU-enabled memory protection for safety-critical firmware execution.

Technical Context

The XE167FM72F80LRABKXUMA1 implements a five-stage pipelined C166-compatible CPU with 16 Mbyte linear address space, background 32/16-bit division (21 cycles), and zero-cycle jump execution. Its interrupt system supports 96 sources across 16 priority levels, with Peripheral Event Controller (PEC) enabling eight-channel, single-cycle data transfers using 24-bit pointers.

On-chip peripherals include two synchronizable A/D converters with broken-wire detection and data preprocessing, six CAN nodes (128 message objects), four CCU6x units for flexible PWM generation, and a programmable watchdog timer with oscillator watchdog. Clock generation uses an internal PLL with selectable operating frequency switching.

FAQ

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

The XE167FM72F80LRABKXUMA1 achieves a maximum CPU clock of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of arithmetic and logical operations. This timing is guaranteed under specified operating conditions (3.0–5.5 V supply, ambient temperature ≤85 °C) and enables deterministic real-time response for motor control loops and CAN message scheduling.

Does this microcontroller support hardware-based memory protection and error correction?

Yes. It integrates a Memory Protection Unit (MPU) enforcing access permissions across its 16 Mbyte address space, and Flash memory includes Error Correction Code (ECC) circuitry that detects and corrects single-bit errors and detects double-bit errors-critical for functional safety compliance in industrial and automotive applications.

How many CAN nodes and message objects does the MultiCAN module support?

The on-chip MultiCAN interface supports up to six independent CAN nodes with a total of 128 configurable message objects. Each node operates per ISO 11898-1 (CAN 2.0B active), supporting both Full CAN and Basic CAN modes, and includes built-in gateway functionality for inter-node message routing without host CPU intervention.

What ADC features enable high-precision motor current sensing?

Its dual 10-bit ADCs provide up to 24 total channels with conversion time below 1 µs, hardware-triggered sampling via CCU6x events, broken-wire detection, and optional data preprocessing (e.g., range checking). These features ensure synchronized, jitter-free current sampling essential for accurate field-oriented control in PMSM and BLDC motor drives.
