Product details
Overview
XE167F72F66LACFXQMA1 from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU, 576 KB on-chip Flash, 32 KB PSRAM, dual 10-bit ADCs (24 channels total), MultiCAN interface with 5 nodes and 128 message objects, and CCU6x 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 XE167F72F66LACFXQMA1 datasheet, XE167F72F66LACFXQMA1 pinout, XE167F72F66LACFXQMA1 application, or XE167F72F66LACFXQMA1 equivalent, key selection criteria include CAN node count, Flash/PSRAM sizing, ADC channel allocation, CCU6 module availability, and LQFP-144 thermal/power delivery capability in real-time embedded systems.
Technical Context
The XE167F72F66LACFXQMA1 implements a five-stage pipeline C166-compatible CPU with single-cycle 16×16 multiply, MAC, and 32-bit arithmetic - enabling deterministic 12.5 ns instruction cycles at 80 MHz. Its memory subsystem includes 576 KB Flash (with ECC support per datasheet Section 4.5), 32 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 (≤1 µs conversion, data preprocessing), four CCU6 modules for independent PWM generation, CAPCOM2 for capture/compare, GPT12E timers, six USIC channels configurable as UART/LIN/SPI/I²C/IIS, and a Rev. 2.0B MultiCAN controller supporting full CAN, basic CAN, and gateway functions across five physical nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C166-compatible 16-bit core with five-stage pipeline, 80 MHz max clock → 12.5 ns instruction cycle for hard real-time loop execution. |
| Flash Memory | 576 KB on-chip Flash with erase/write endurance and programming voltage support → sufficient for complex motor control firmware with bootloader and safety routines. |
| ADC System | Dual 10-bit ADCs, up to 24 total input channels, ≤1 µs conversion time, hardware range check → enables simultaneous current/voltage sensing in 3-phase inverters. |
| MultiCAN Interface | Rev. 2.0B compliant, 5 CAN nodes, 128 message objects, full/basic CAN support → meets automotive-grade networked control requirements in industrial gateways. |
| CCU6 Modules | Four independent CCU6 units with dead-time insertion, shadow transfer, and emergency shutdown → supports multi-axis servo drive PWM with functional safety timing constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XE167F-96F66L | 768 KB Flash, 64 KB PSRAM, same peripherals and package | Supports larger firmware images (e.g., dual-bank OTA, extended safety libraries) | Select when firmware size exceeds 576 KB or when future-proofing for feature expansion is required. |
| SAF-XE167G-72F66L | Same Flash/PSRAM but only 2 CAN nodes and 4 USIC channels; CCU6 modules limited to 0 and 1 | Suitable for cost-sensitive body electronics without gateway or multi-node networking needs | Choose for non-gateway applications where CAN node count and serial channel count can be reduced by 40–60%. |
Compared with SAF-XE167F-96F66L, this part trades 192 KB Flash and 32 KB PSRAM for lower cost and identical real-time peripheral latency; versus SAF-XE167G-72F66L, it adds three CAN nodes and two USIC channels - enabling distributed architecture scalability without changing PCB layout.

FAQ
What is the maximum operating frequency and associated instruction cycle time?
The XE167F72F66LACFXQMA1 achieves a maximum CPU clock of 80 MHz, resulting in a 12.5 ns instruction cycle time for single-cycle operations including 16×16 multiply, 32-bit add/subtract, and MAC. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40 °C to +85 °C) conditions per Section 4.4 of the datasheet.
Does this device support hardware-based functional safety features for IEC 61508 or ISO 26262 compliance?
Yes - it includes dual lockstep-capable watchdog timers (programmable and oscillator watchdog), memory protection units (MPU) for SRAM/Flash access control, parity/ECC on critical memories, and hardware-triggered safe state entry via TRAP/NMI pins. These features form the foundation for ASIL-B decomposition in motor control applications per Infineon's safety manual.
How many independent PWM channels can be generated simultaneously using CCU6 modules?
Four CCU6 modules are implemented, each providing three complementary PWM outputs with independent dead-time control, shadow transfer, and emergency stop capability. This yields up to 12 fully independent, synchronized PWM channels - sufficient for dual 3-phase inverter control or multi-motor servo systems.
Is external RAM required for typical motor control applications?
No - the device integrates 576 KB Flash, 32 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM, collectively covering code storage, stack/heap, real-time buffers, and backup data retention. External RAM is optional and only needed for applications exceeding 64 KB of active data working set, such as advanced observer-based control algorithms.
