Product details
Overview
SAF-XE167K-48F66LAC from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU, 384 KB on-chip Flash, 16 KB PSRAM, dual 10-bit ADCs (8+8 channels), CCU6x PWM units, and four serial interface channels - all in a 144-pin LQFP package. It targets motor control, industrial automation, and embedded power conversion where deterministic timing, analog integration, and multi-channel PWM are required.
For engineers reviewing the SAF-XE167K-48F66LAC datasheet, SAF-XE167K-48F66LAC pinout, SAF-XE167K-48F66LAC application, or SAF-XE167K-48F66LAC equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities, and precise alternative part comparisons for industrial real-time control design.
Technical Context
The XE167K integrates a five-stage pipeline C166-compatible CPU with single-cycle 16×16 multiply, MAC, and 12.5 ns instruction cycle at 80 MHz. Its memory subsystem includes 384 KB Flash (with ECC), 16 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM - all mapped within a unified 16 MB linear address space.
Peripheral architecture centers on deterministic real-time I/O: two synchronizable 10-bit ADCs (conversion time <1 µs), dual CCU6 modules supporting complementary PWM with dead-time control, four serial channels (configurable as UART/LIN/SPI/I²C), and no MultiCAN - distinguishing it from F/G/H variants. Clock generation uses internal PLL with external crystal or oscillator input.
Key Specifications

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-XE167G-48F66L | Includes 2 CAN nodes (Rev. 2.0B); same Flash/PSRAM/ADC/PWM specs | Required for CANopen-based motion networks; adds CAN PHY interface and message object RAM | Select when CAN bus integration is mandatory and serial channel count can be reduced from 4 to 4 (no net change) |
| SAF-XE167H-48F66L | No CAN, 6 serial channels (vs. 4), identical Flash/PSRAM/ADC/PWM | Better suited for UART/SPI-dense systems like multi-protocol gateways or display controllers | Choose when additional serial interfaces outweigh CAN capability - e.g., RS-485 + SPI + I²C + LIN + two UARTs |
Compared with SAF-XE167G-48F66L and SAF-XE167H-48F66L, the SAF-XE167K-48F66LAC offers optimal balance for non-CAN, serial-constrained industrial controllers - retaining full ADC and PWM capability while minimizing pin count and BOM cost where CAN is unused.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The SAF-XE167K-48F66LAC operates at up to 80 MHz CPU clock frequency, delivering a 12.5 ns instruction cycle time. This is achieved using the on-chip PLL with external crystal or oscillator input, and is validated across the full −40 °C to +85 °C temperature range per datasheet Section 4.4.
Does this device support hardware-accelerated motor control functions?
Yes - it includes dedicated peripherals for motor control: dual CCU6 modules with complementary PWM outputs, dead-time insertion, and shadow register update; two synchronizable 10-bit ADCs with hardware trigger inputs tied to PWM events; and a Peripheral Event Controller for zero-CPU ADC-to-PWM data movement.
Is there on-chip debug capability, and what interface does it use?
The device features On-Chip Debug Support (OCDS) compliant with JTAG IEEE 1149.1. It supports hardware breakpoints, real-time trace, and non-intrusive debugging of time-critical code - confirmed in Section 3.5 of the V2.1 datasheet and supported by Infineon's DAS and iC500 debug tools.
What are the key differences between SAF-XE167K-48F66LAC and SAF-XE167F-48F66L?
The K-derivative omits the MultiCAN module (0 CAN nodes vs. 5) and reduces serial interface count from 6 to 4 USIC channels, while retaining identical Flash (384 KB), PSRAM (16 KB), ADC (8+8 channels), and CCU6 (0,1) configuration - making it optimized for CAN-free, cost-sensitive industrial control applications.
