Infineon Technologies XE164F48F66LACFXUMA1

Overview

XE164F48F66LACFXUMA1 from Infineon Technologies is a 16-bit real-time signal controller with 384 KB on-chip Flash, 16 KB PSRAM, 80 MHz CPU clock (12.5 ns instruction cycle), dual 10-bit ADCs (11+5 channels), and integrated MultiCAN Rev. 2.0B interface supporting up to 4 CAN nodes. It targets motor control, industrial automation, and power conversion systems requiring deterministic timing and mixed-signal integration.

For engineers reviewing the XE164F48F66LACFXUMA1 datasheet, XE164F48F66LACFXUMA1 pinout, XE164F48F66LACFXUMA1 application, or XE164F48F66LACFXUMA1 equivalent, key selection criteria include Flash size, CAN node count, ADC channel configuration, CCU6 module presence, and LQFP-100 package compatibility with industrial temperature range (−40 °C to +85 °C).

Technical Context

The XE164F48F66LACFXUMA1 implements a five-stage pipelined C166-compatible CPU core with single-cycle 16×16 multiply, MAC, and zero-cycle jumps. Its memory subsystem includes 384 KB Flash, 16 KB PSRAM, 2 KB DPRAM, 1 KB SBRAM, and supports up to 12 MB external address space via configurable bus interface.

Peripheral integration centers on real-time signal processing: two synchronizable 10-bit ADCs (≤1 µs conversion), three CCU6 modules for PWM generation, CAPCOM2 (16-channel), GPT12E timer, MultiCAN with 128 message objects, and six serial interfaces (UART/LIN/SPI/I²C/IIS). Clock generation uses internal PLL with external crystal or oscillator input.

FAQ

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

The XE164F48F66LACFXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of arithmetic, logic, and branch instructions. 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.

Does this device support hardware-based PWM dead-time insertion?

Yes-each of the three CCU6 modules provides dedicated hardware dead-time generators with programmable delay (down to one CPU clock cycle), enabling safe complementary PWM output for IGBT or MOSFET half-bridge drivers without software intervention or CPU overhead.

How many CAN message objects does the MultiCAN module support?

The MultiCAN module supports up to 128 message objects across its four CAN nodes, with configurable acceptance filtering, transmit/receive prioritization, and automatic retransmission. This allows concurrent handling of multiple CAN identifiers and data rates within a single controller instance.

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

Yes-on-chip debug support is provided via the JTAG interface compliant with IEEE 1149.1, implementing Infineon's On-Chip Debug Support (OCDS) architecture. It enables real-time trace, hardware breakpoints, register access, and memory inspection without halting real-time peripheral operation.
