Infineon Technologies XE167G72F66LACFXQMA1

Overview

XE167G72F66LACFXQMA1 from Infineon Technologies is a 16-bit real-time signal controller with 576 KB on-chip Flash, 32 KB PSRAM, dual 10-bit ADCs (16+8 channels), CCU6 PWM units (0 & 1), and 2 CAN nodes. It operates at up to 80 MHz, supports 3.0–5.5 V supply, and targets motor control and industrial automation systems requiring deterministic timing and integrated analog/motor interface.

For engineers reviewing the XE167G72F66LACFXQMA1 datasheet, XE167G72F66LACFXQMA1 pinout, XE167G72F66LACFXQMA1 application, or XE167G72F66LACFXQMA1 equivalent, key selection criteria include Flash size, CAN node count, ADC channel allocation, CCU6 module availability, and LQFP-144 package compatibility for high-pin-count real-time control designs.

Technical Context

The XE167G72F66LACFXQMA1 implements a five-stage pipelined C166-compatible CPU core delivering 12.5 ns instruction cycle time at 80 MHz, with single-cycle 16×16 multiply and MAC operations. Its interrupt system supports 16 priority levels across 87 sources, with 12.5 ns sample rate and Peripheral Event Controller (PEC) for zero-overhead DMA transfers.

It integrates two synchronized 10-bit ADCs (ADC0: 16 channels; ADC1: 8 channels), each with sub-1 µs conversion time and optional data preprocessing. The CCU6x unit (modules 0 and 1 enabled) provides six-channel PWM generation with dead-time insertion and emergency shutdown, while the MultiCAN interface supports two independent CAN 2.0B nodes with 64 message objects per node.

FAQ

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

The XE167G72F66LACFXQMA1 achieves a maximum CPU clock of 80 MHz, resulting in a 12.5 ns instruction cycle time. This is enabled by its five-stage pipeline architecture and internal PLL, which accepts external crystal inputs from 1–20 MHz and multiplies them to generate the core clock. All arithmetic and logical instructions execute in one cycle at this speed.

Does this device support hardware-accelerated motor control functions?

Yes - it integrates dedicated hardware including CCU6 modules (0 and 1) for six-channel complementary PWM with dead-time insertion and emergency stop, dual synchronized 10-bit ADCs with trigger synchronization to PWM events, and a Peripheral Event Controller (PEC) that enables zero-CPU-overhead data transfers for current sensing and feedback loops.

How many CAN nodes and message objects does the XE167G72F66LACFXQMA1 support?

This derivative supports exactly two CAN 2.0B-compliant nodes, each with up to 64 message objects (128 total), enabling independent communication on separate CAN buses. Unlike the F-series variant, it does not support CAN gateway functionality between more than two networks, limiting inter-subsystem routing capability.

Is there on-chip debug capability, and what interface does it use?

Yes - the device includes full On-Chip Debug Support (OCDS) compliant with IEEE 1149.1 (JTAG). It supports real-time debugging features including hardware breakpoints, watchpoints, trace buffer capture, and non-intrusive program flow monitoring without halting CPU execution, all accessible through standard JTAG debug probes.
