Infineon Technologies XE164F96F66LACFXUMA1

Overview

XE164F96F66LACFXUMA1 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 A/D converters (11+5 channels, 10-bit, <1 µs conversion), and MultiCAN interface with 4 nodes and 128 message objects. It targets motor control, industrial automation, and power electronics where deterministic timing, high-resolution PWM, and CAN-based system coordination are required.

For engineers reviewing the XE164F96F66LACFXUMA1 datasheet, XE164F96F66LACFXUMA1 pinout, XE164F96F66LACFXUMA1 application, or XE164F96F66LACFXUMA1 equivalent, key selection criteria include its 80 MHz real-time execution capability, integrated CCU6x PWM units for three-phase inverter control, dual 10-bit ADCs with hardware preprocessing, and full CAN 2.0B support across four independent nodes.

Technical Context

The XE164F96F66LACFXUMA1 implements a five-stage pipelined C166S-V2 core with zero-cycle jumps, 1-cycle MAC, and fast context switching via dual local register banks. Its memory subsystem includes 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 centers on real-time signal processing: two synchronizable 10-bit ADCs (16 total channels, hardware range check/data reduction), three CCU6x units for independent 3-phase PWM generation, CAPCOM2 for general-purpose capture/compare, GPT12E timers, and a MultiCAN module supporting up to 4 CAN nodes with gateway functionality and 128 message objects.

Key Specifications

Pinout & Package

XE164F96F66LACFXUMA1 is housed in a 100-pin Green LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across multiple voltage domains (M, P, I/O), including dedicated XTAL1/XTAL2 inputs for crystal oscillator operation, JTAG debug interface pins (TCK, TMS, TDI, TDO, TRST), and grouped peripheral signals for CAN, USIC, ADC, and CCU6x.

FAQ

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

The XE164F96F66LACFXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time. This timing is achieved using the on-chip PLL with external crystal or clock input, and applies to single-cycle instructions including 16×16 multiply and 32-bit add/subtract operations.

Does this device support hardware-accelerated motor control functions?

Yes - it integrates three CCU6x units for independent 3-phase PWM generation with programmable dead-time, fault blanking, and synchronization triggers; dual 10-bit ADCs with hardware range checking and data reduction; and a Peripheral Event Controller for automatic ADC-to-PWM data transfer without CPU involvement.

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

The MultiCAN module supports up to 4 independent CAN nodes with a total of 128 configurable message objects. Each node operates under CAN 2.0B protocol with full acceptance filtering, and gateway functionality allows message forwarding between nodes without host CPU intervention.

Is there on-chip debug support, and what interface is used?

Yes - on-chip debug support is provided via the JTAG interface compliant with IEEE 1149.1. It enables full boundary scan, flash programming, real-time breakpoint setting, and register visibility during execution, with dedicated TCK, TMS, TDI, TDO, and TRST pins in the 100-pin LQFP package.
