Product details
Overview
SAF-XE167KM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU clock (12.5 ns instruction cycle), 576 KB on-chip Flash, dual 10-bit ADCs with ≤1 μs conversion time and 24 channels, MultiCAN Rev. 2.0B interface with 128 message objects across up to 6 nodes, and CCU6x PWM units for motor control in industrial drives.
For engineers reviewing the SAF-XE167KM-48F80L AA datasheet, SAF-XE167KM-48F80L AA pinout, SAF-XE167KM-48F80L AA application, or SAF-XE167KM-48F80L AA equivalent, key selection criteria include deterministic real-time interrupt latency (96 sources, 16 priority levels), on-chip memory protection (MPU + ECC), external bus support (12 MB address space), and integrated debug via JTAG/DAP.
Technical Context
The XE167KM implements a C166-compatible five-stage pipeline CPU with zero-cycle jumps, one-cycle MAC, and background 32/16-bit division in 21 cycles. It integrates a Memory Protection Unit (MPU), hardware CRC checker with programmable polynomial, and dual-port RAM (2 KB DPRAM) for concurrent access by CPU and peripherals.
Its peripheral subsystem includes two synchronizable 10-bit ADCs with broken-wire detection and data preprocessing, six CAN nodes with gateway functionality, four CCU6x units supporting center-aligned PWM, and a Peripheral Event Controller (PEC) enabling single-cycle DMA transfers with 24-bit addressing across the full 16 MB linear space.
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-XE167HM-48F80L AA | Includes 1 MB Flash (vs. 576 KB), adds Ethernet MAC interface, and supports higher ambient temperature (125°C vs. 105°C). | Suitable for Ethernet-connected industrial gateways where network stack memory footprint exceeds 576 KB. | Select when Ethernet connectivity or extended temperature operation is required; otherwise, XE167KM offers optimal cost/performance for CAN-centric designs. |
| SAF-XE164KM-48F66L AA | Lower 66 MHz CPU clock, reduced Flash (384 KB), no MultiCAN gateway mode, and only 4 CCU6x units. | Targeted at cost-sensitive single-axis motor drives without multi-bus routing needs. | Choose for simpler motion control applications where 80 MHz performance and 6-CAN-node routing are unnecessary. |
Compared with XE167HM, the XE167KM trades Ethernet and extended temperature for lower BOM cost and identical CAN/PWM/ADC feature set; versus XE164KM, it delivers 21% higher CPU throughput, 50% more Flash, and full gateway capability-making it the balanced choice for mid-tier industrial automation.

FAQ
What is the maximum operating temperature for SAF-XE167KM-48F80L AA?
The SAF-XE167KM-48F80L AA is rated for operation from –40°C to +105°C ambient temperature. This rating is validated per Infineon's qualification standards and applies to all electrical specifications in the datasheet, including Flash endurance and ADC accuracy. Thermal derating is not required within this range when PCB layout follows recommended copper pour and via guidelines.
Does SAF-XE167KM-48F80L AA support JTAG debugging in production firmware?
Yes-SAF-XE167KM-48F80L AA includes full on-chip debug support via JTAG and Device Access Port (DAP), with unrestricted access to CPU registers, memory, and peripheral configuration during active firmware execution. Debug authentication is disabled by default; no fuse programming or security lock is applied unless explicitly enabled by the user.
Can the internal PLL generate frequencies other than 80 MHz?
The internal PLL supports programmable multiplication factors (N = 1–127) and division ratios (M = 1–16), allowing output frequencies from 10 MHz to 80 MHz based on a 1–20 MHz crystal or external clock. The 80 MHz configuration uses a 10 MHz crystal with N=8, M=1; alternative configurations require reprogramming PLLCON registers and verifying lock status before CPU clock switch.
How many CAN message objects are allocated per node in MultiCAN mode?
The MultiCAN module allocates message objects dynamically across its 128 total object slots. Each of the six CAN nodes can be configured with up to 128 objects, but practical allocation depends on application needs-for example, 20 objects per node (120 total) leaves 8 for shared gateway buffers. Object assignment is done via CAN_MOFCR register writes during initialization.
