Infineon Technologies XE167F96F66LACFXUMA1

Overview

XE167F96F66LACFXUMA1 from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU, 768 KB on-chip Flash, 64 KB PSRAM, dual 10-bit ADCs (24 channels total), MultiCAN interface with 5 nodes and 128 message objects, and CCU6 PWM units for motor control. It operates from 3.0–5.5 V and targets industrial motor drives requiring deterministic timing and integrated analog/peripheral co-processing.

For engineers reviewing the XE167F96F66LACFXUMA1 datasheet, XE167F96F66LACFXUMA1 pinout, XE167F96F66LACFXUMA1 application, or XE167F96F66LACFXUMA1 equivalent, key selection criteria include CAN node count, ADC channel resolution and preprocessing capability, PSRAM size for real-time buffer allocation, CCU6 module availability for high-precision PWM generation, and LQFP-144 package compatibility with existing PCB layouts.

Technical Context

The XE167F96F66LACFXUMA1 implements a five-stage pipelined C166-compatible CPU core with single-cycle 16×16 multiply, MAC, and 32-bit arithmetic - enabling sub-microsecond interrupt response and deterministic loop execution in motor control algorithms. Its memory subsystem integrates 768 KB Flash (with ECC), 64 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM, all mapped within a unified 16 MB linear address space.

Peripheral integration includes two synchronizable 10-bit ADCs (conversion time <1 µs, range-check preprocessing), four CCU6 modules supporting center-aligned PWM with dead-time insertion, six serial interface channels (UART/LIN/SPI/I²C/IIS), and a Rev. 2.0B MultiCAN controller with full CAN/Basic CAN support across five independent nodes - all accessible via dedicated DMA channels managed by the Peripheral Event Controller (PEC).

FAQ

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

The XE167F96F66LACFXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of core arithmetic and logic operations. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40 °C to +85 °C) conditions per the V2.1 datasheet, and enables deterministic execution of motor control loops with ≤1 µs jitter.

Does this device support functional safety standards such as ISO 26262?

The XE167F96F66LACFXUMA1 includes hardware features aligned with ASIL-B requirements-including lockstep-capable memory protection, ECC on Flash and SRAM, watchdog timers with independent clock sources, and configurable error correction for peripheral registers. While not pre-certified, Infineon provides safety manuals and FMEDA reports to support customer-led ISO 26262 development workflows.

How many independent PWM channels can be generated simultaneously?

This device supports up to 24 independent PWM output channels via four CCU6 modules (each providing 6 PWM outputs). All channels are fully configurable for center-aligned or edge-aligned modes, with programmable dead-time insertion, fault input synchronization, and automatic emergency shutdown-enabling full-bridge, three-phase, and multi-motor control topologies.

Is external memory expansion supported, and what bus configurations are available?

Yes, the XE167F96F66LACFXUMA1 supports up to 12 MB of external memory via its External Bus Controller (EBC), with programmable bus characteristics including multiplexed or demultiplexed address/data buses, 8-bit or 16-bit data width, five chip-select signals, and hold/hold-acknowledge arbitration. Timing parameters are configurable per address range to interface with SDRAM, NOR Flash, or FPGA peripherals.
