Product details
Overview
SAF-XE167KM-72F80L AA from Infineon Technologies is a 16-bit real-time signal controller in the XE166 family, designed for motor control and industrial automation systems. It features an 80 MHz CPU with 12.5 ns instruction cycle, 576 KB on-chip Flash, 16 KB DSRAM, dual 10-bit ADCs (24 channels, <1 µs conversion), MultiCAN interface (6 nodes, 128 message objects), and CCU6x PWM units for precise timing-critical actuation.
For engineers reviewing the SAF-XE167KM-72F80L AA datasheet, SAF-XE167KM-72F80L AA pinout, SAF-XE167KM-72F80L AA application, or SAF-XE167KM-72F80L AA equivalent, key selection criteria include deterministic interrupt latency (96 sources, 16 priority levels), integrated memory protection (MPU + ECC), external bus support (12 MB address space), and CAN/LIN/USIC serial interface flexibility for embedded real-time control.
Technical Context
The SAF-XE167KM-72F80L AA implements a C166-compatible five-stage pipeline CPU with zero-cycle jumps, one-cycle MAC, and background 32/16-bit division in 21 cycles. Its memory subsystem includes 576 KB Flash with ECC, 16 KB DSRAM, 32 KB PSRAM, 8 KB SBRAM, and 2 KB DPRAM - all mapped within a unified 16 MB linear address space.
Real-time peripherals include two synchronizable 10-bit ADCs (24 total channels, broken-wire detection), six independent CAN nodes with gateway capability, four CCU6x units for high-resolution PWM generation, and a Peripheral Event Controller (PEC) enabling single-cycle data transfers across 24-bit address space without CPU intervention.

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-XE164HM-40F66L AA | Lower clock speed (66 MHz), reduced Flash (384 KB), no MultiCAN gateway, only 4 CCU6 units. | Suitable for cost-sensitive single-motor drives without multi-bus networking. | Select when CAN gateway and >66 MHz performance are not required; lower power consumption at same voltage. |
| SAK-TC275T-64F200N AC | TriCore™ 32-bit CPU (200 MHz), 4 MB Flash, Ethernet MAC, AURIX™ safety features (ASIL-D), no legacy C166 compatibility. | Targets next-gen automotive ADAS and safety-critical chassis control where ISO 26262 certification is mandatory. | Choose for new designs requiring functional safety certification and higher compute throughput; migration requires full software re-architecture. |
Compared with SAF-XE164HM-40F66L AA, the SAF-XE167KM-72F80L AA delivers 21% higher CPU throughput and full CAN gateway capability; versus SAK-TC275T-64F200N AC, it offers C166 toolchain continuity and lower system-level complexity for established industrial motor control platforms.

FAQ
What is the maximum operating temperature range for SAF-XE167KM-72F80L AA?
The SAF-XE167KM-72F80L AA is rated for industrial temperature operation from –40 °C to +125 °C ambient, with junction temperature limits defined per Infineon's thermal derating guidelines in Section 5.2 of the datasheet. Thermal resistance (RθJA) is 32 K/W for the 144-pin LQFP package under standard JEDEC 2S2P board conditions.
Does SAF-XE167KM-72F80L AA support bootloading over CAN or UART?
Yes - the device integrates on-chip bootstrap loaders supporting firmware updates via CAN 2.0B and UART interfaces, as documented in Section 2.2 and Application Note AP32164. The bootloader resides in protected ROM and supports secure flash programming with checksum validation before execution.
How many independent PWM channels can be generated using CCU6x units?
The SAF-XE167KM-72F80L AA integrates four CCU6x units, each capable of generating up to three complementary PWM outputs with programmable dead time. This enables up to 12 independent high-resolution PWM channels - sufficient for dual 3-phase inverter control or multi-motor systems.
Is the internal Flash memory accessible for EEPROM emulation?
Yes - the 576 KB Flash supports sector-wise erase and byte-programming, and Infineon provides DAVE™ library functions (e.g., FLASH_EEPROM_EMULATION) for wear-leveling and data retention management.
