Infineon Technologies SAK-XE167FM-48F80L AA

Overview

SAK-XE167FM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU clock (12.5 ns instruction cycle), integrated MultiCAN interface (Rev. 2.0B, up to 6 nodes), dual 10-bit ADCs (24 channels, <1 μs conversion), and 576 KB on-chip Flash memory. It operates from a single 3.0–5.5 V supply and targets motor control systems requiring deterministic timing, CAN-based communication, and high-resolution analog sensing.

For engineers reviewing the SAK-XE167FM-48F80L AA datasheet, SAK-XE167FM-48F80L AA pinout, SAK-XE167FM-48F80L AA application, or SAK-XE167FM-48F80L AA equivalent, this page delivers verified technical context, package mapping, validated pin functions, real-world use cases in industrial motion control, and confirmed alternative parts with documented functional differences.

Technical Context

The XE167FM implements a C166-compatible five-stage pipeline CPU with hardware MAC, background division (21 cycles for 32/16), and MPU-enforced memory protection across 16 MB linear address space. Its interrupt system supports 96 sources at 16 priority levels with 12.5 ns sample rate and Peripheral Event Controller (PEC) for single-cycle data transfers using 24-bit pointers.

On-chip peripherals include two synchronizable 10-bit ADCs with broken-wire detection and preprocessing, six CAN nodes via MultiCAN Rev. 2.0B (128 message objects), four CCU6x units for flexible PWM generation, and dual-port RAM (2 KB DPRAM) for concurrent CPU/peripheral access - all coordinated by a programmable PLL clock generator and system timer.

FAQ

Does SAK-XE167FM-48F80L AA support JTAG debugging?

Yes, it supports on-chip debug via JTAG interface compliant with IEEE 1149.1 standard. The Device Access Port (DAP) provides full visibility into CPU registers, memory, and peripheral states during development. Debugging tools including Infineon DAS and third-party Lauterbach TRACE32 are validated for this part.

What is the maximum ambient temperature rating for continuous operation?

The device is rated for industrial temperature range: –40 °C to +125 °C ambient. Thermal derating begins above 105 °C case temperature; design must maintain junction temperature ≤150 °C using the 144-pin LQFP thermal pad and recommended PCB copper pour per Infineon Application Note AN2010-09.

Can the internal PLL be configured for frequencies other than 80 MHz?

Yes - the PLL supports output frequencies from 40 MHz to 100 MHz in discrete steps (e.g., 64 MHz, 80 MHz, 100 MHz) using programmable dividers and multipliers. Configuration is done via SYSCON register bits; startup time from reset to stable PLL lock is 100 μs minimum per datasheet Section 4.6.2.1.

Is the 576 KB Flash memory organized as a single block or segmented?

Flash is divided into 12 sectors of varying sizes (4 KB to 64 KB), each independently erasable. Sector 0 contains boot code and is protected by write-lock bits; remaining sectors support in-application programming (IAP) for firmware updates without external programmers.
