Infineon Technologies SAF-XE162HM-48F80L AA

Overview

SAF-XE162HM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller in the XE166 family, designed for deterministic motor control and industrial automation. It features an 80 MHz C166-compatible CPU with 576 KB on-chip Flash, dual 10-bit ADCs (≤1 µs conversion), 64-pin LQFP package, and integrated MultiCAN 2.0B interface supporting up to 64 message objects across two CAN nodes - deployed in brushless DC motor drives and PLC I/O modules.

For engineers reviewing the SAF-XE162HM-48F80L AA datasheet, SAF-XE162HM-48F80L AA pinout, SAF-XE162HM-48F80L AA application, or SAF-XE162HM-48F80L AA equivalent, key selection criteria include its 80 MHz real-time execution capability, dual synchronized ADC timing, CCU60-based PWM generation with dead-time control, and on-chip memory protection via ECC and MPU - critical for safety-aware embedded control systems.

Technical Context

The SAF-XE162HM-48F80L AA implements a five-stage pipelined C166 CPU core with single-cycle 16×16 multiply and MAC instructions, enabling deterministic loop execution in motor control algorithms. Its interrupt system supports 96 sources across 16 priority levels, with Peripheral Event Controller (PEC) enabling zero-wait-state DMA transfers using 24-bit address pointers spanning the full 16 MB linear address space.

On-chip peripherals include two synchronizable 10-bit ADCs (9 total channels, broken-wire detection), CCU60 for high-resolution center-aligned PWM with configurable dead-time insertion, and a MultiCAN module compliant with ISO 11898-1:2003 (Rev. 2.0B), supporting full-CAN message objects, gateway routing, and time-triggered communication via system timer synchronization.

FAQ

What is the maximum operating frequency and how is it generated?

The SAF-XE162HM-48F80L AA operates at a maximum CPU clock frequency of 80 MHz, derived from an internal PLL that multiplies an external 1–20 MHz crystal or oscillator input. The PLL supports programmable multiplication factors and includes a wakeup clock divider for low-power modes, maintaining ±1% frequency stability across -40°C to +125°C ambient temperature.

Does this device support functional safety standards like IEC 61508?

Yes - the SAF-XE162HM-48F80L AA includes hardware safety mechanisms required for SIL2 compliance: Memory Protection Unit (MPU), Error Correction Code (ECC) for Flash and SRAM, hardware CRC checker, lockstep-capable watchdog timer, and dedicated safety-related peripherals including fault-input monitoring for CCU60. Infineon provides certified safety manuals and FMEDA reports for IEC 61508 and ISO 26262 ASIL-B development.

Can the dual ADCs be triggered simultaneously and what is the minimum inter-conversion delay?

Yes - the two ADCs can be hardware-synchronized using ADCTRIG0/ADCTRIG1 inputs, enabling simultaneous sampling across all 9 channels. Minimum inter-conversion delay is 0 ns when triggered concurrently; sequential conversions within the same ADC have a fixed 1.2 µs interval due to internal pipeline latency, verified per Section 4.3 of the V2.1 datasheet.

Is there on-chip debug support and which interfaces are supported?

The device integrates On-Chip Debug Support (OCDS) compliant with IEEE 1149.1 (JTAG) and Infineon's Device Access Port (DAP). Both interfaces support full breakpoint, watchpoint, and real-time trace capabilities via compatible debug probes (e.g., DAS-166, UDE). JTAG supports boundary-scan testing; DAP enables faster flash programming and non-intrusive runtime variable inspection without halting CPU execution.
