Infineon Technologies SAF-XE167FM-48F80L AA

Overview

SAF-XE167FM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller with C166™ CPU core, 80 MHz operation, 576 KB on-chip Flash, 16 KB DSRAM, and integrated MultiCAN (Rev. 2.0B), dual 10-bit ADCs (24 channels, <1 µs conversion), and CCU6x PWM units. It targets motor control, industrial automation, and power conversion systems requiring deterministic timing and mixed-signal integration.

For engineers reviewing the SAF-XE167FM-48F80L AA datasheet, SAF-XE167FM-48F80L AA pinout, SAF-XE167FM-48F80L AA application, or SAF-XE167FM-48F80L AA equivalent, key selection criteria include Flash ECC protection, 12.5 ns instruction cycle at 80 MHz, 119 GPIOs, 6 CAN nodes with gateway support, and 144-pin LQFP package thermal performance.

Technical Context

The XE167FM implements a five-stage pipelined C166-compatible CPU with MPU, supporting single-cycle 16×16 multiply and MAC operations, and background 32/16 division in 21 cycles. Its memory subsystem includes 576 KB Flash with ECC, 16 KB DSRAM, 32 KB PSRAM, and 8 KB SBRAM - all mapped within a unified 16 MB linear address space.

Peripheral integration centers on real-time control: two synchronizable 10-bit ADCs (24 total channels, broken-wire detection), four CCU6x units for flexible PWM generation, CAPCOM2 (16-channel), GPT12E timers, and a six-node MultiCAN module compliant with ISO 11898-1 Rev. 2.0B, supporting up to 128 message objects and gateway functionality.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The SAF-XE167FM-48F80L AA operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time for single-cycle execution of most instructions. This timing is achieved using the on-chip PLL with an external crystal or clock source between 1 MHz and 20 MHz, and is validated across the full industrial temperature range (–40 °C to +125 °C).

Does this device support hardware memory protection and error correction?

Yes - it integrates a Memory Protection Unit (MPU) enforcing access rights across its 16 MB linear address space, and all on-chip Flash memory includes Error Correction Code (ECC) circuitry capable of detecting and correcting single-bit errors, essential for functional safety compliance in IEC 61508 SIL-2 systems.

How many CAN nodes and message objects does the MultiCAN module support?

The MultiCAN module supports up to six independent CAN nodes, each configurable for Full CAN or Basic CAN operation, with a total of 128 message objects distributed across nodes. It implements ISO 11898-1 Rev. 2.0B and includes gateway functionality for message forwarding between nodes without CPU intervention.

Is JTAG debugging supported, and what interfaces are available?

Yes - on-chip debug support is provided via both IEEE 1149.1 JTAG and Infineon's Device Access Port (DAP). The JTAG interface uses TRST, TCK, TMS, TDO, and TDI pins and supports full breakpoint, watchpoint, and real-time trace capabilities through compatible debug probes like DAS500 or UDE.
