Infineon Technologies XE167H96F66LACFXUMA1

Overview

XE167H96F66LACFXUMA1 from Infineon Technologies is a 16-bit real-time signal controller with 768 KB on-chip Flash, 64 KB PSRAM, dual 10-bit ADCs (24 channels total), four CCU6 PWM units, and six serial interface channels (UART/LIN/SPI/I²C/IIS). It operates at up to 80 MHz, supports single-cycle MAC and 32-bit arithmetic, and targets motor control and industrial automation systems requiring deterministic timing and high peripheral integration.

For engineers reviewing the XE167H96F66LACFXUMA1 datasheet, XE167H96F66LACFXUMA1 pinout, XE167H96F66LACFXUMA1 application, or XE167H96F66LACFXUMA1 equivalent, key selection criteria include Flash size, CAN absence vs. serial channel count, CCU6 module availability, ADC sampling rate (<1 µs), and LQFP-144 package compatibility with industrial PCB layouts.

Technical Context

The XE167H96F66LACFXUMA1 implements a five-stage pipelined C166-compatible CPU core with 12.5 ns instruction cycle at 80 MHz, supporting zero-cycle jumps and fast context switching via dual local register banks. Its memory subsystem includes 768 KB Flash, 64 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM - all mapped within a unified 16 MB linear address space.

Peripheral architecture integrates two synchronizable 10-bit ADCs (24-channel total, <1 µs conversion), four independent CCU6 units for flexible PWM generation, six USIC modules configurable as UART/LIN/SPI/I²C/IIS, and a GPT12E timer unit with five timers - all coordinated by a 24-bit PEC for interrupt-driven data transfers without CPU overhead.

FAQ

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

The XE167H96F66LACFXUMA1 achieves a maximum CPU clock of 80 MHz, resulting in a 12.5 ns instruction cycle time. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (-40 °C to +85 °C) conditions, enabling deterministic execution of real-time control loops with sub-microsecond jitter.

Does this device include CAN functionality?

No, the XE167H96F66LACFXUMA1 explicitly omits the MultiCAN module present in the 'F' and 'G' derivatives. It provides six USIC serial channels instead, configurable as UART, LIN, SPI, I²C, or IIS - making it suitable for non-CAN industrial systems requiring high serial throughput and flexibility.

How is the ADC subsystem structured and what is its performance envelope?

The device integrates two independent 10-bit SAR ADCs (ADC0 and ADC1) with up to 24 total input channels (16+8). Each ADC achieves <1 µs conversion time, supports hardware triggering from CCU6 or timers, and includes optional preprocessing such as range checking and data reduction - optimized for current sensing and position feedback in motor control.

What debug and programming interfaces are supported?

XE167H96F66LACFXUMA1 supports IEEE 1149.1-compliant JTAG for full on-chip debug support (OCDS), including real-time trace, breakpoints, and flash programming. It also includes a ROM-resident bootloader accessible via UART or USIC channels, enabling field firmware updates without dedicated debug hardware.
