Product details
Overview
SAF-XE167GM-48F80L AA from Infineon Technologies is a 16-bit real-time signal controller featuring an 80 MHz CPU clock (12.5 ns instruction cycle), dual 10-bit ADCs with ≤1 μs conversion time and up to 24 channels, MultiCAN Rev. 2.0B interface with 128 message objects across 6 nodes, 576 KB on-chip Flash, and 119 GPIO lines - deployed in motor control systems for industrial servo drives requiring deterministic timing and integrated analog capture.
For engineers reviewing the SAF-XE167GM-48F80L AA datasheet, SAF-XE167GM-48F80L AA pinout, SAF-XE167GM-48F80L AA application, or SAF-XE167GM-48F80L AA equivalent, key selection criteria include CAN node count, ADC channel concurrency, SRAM partitioning (SBRAM/DPRAM/DSRAM/PSRAM), PLL-based clock flexibility, and hardware CRC/ECC memory protection for safety-critical firmware execution.
Technical Context
The XE167GM 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 interrupt system supports 96 sources across 16 priority levels, with Peripheral Event Controller (PEC) enabling single-cycle data transfers using 24-bit address pointers spanning the full 16 MB linear space.
On-chip peripherals include two synchronizable 10-bit ADCs (24 total channels, broken-wire detection), four CCU6x units for independent PWM generation, six MultiCAN nodes with gateway capability, and programmable external bus supporting multiplexed/demultiplexed 8-/16-bit data paths across five chip-select ranges - all coordinated by a unified clock tree with PLL, prescaler, and wakeup oscillator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock Speed | 80 MHz - enables 12.5 ns instruction cycle for deterministic real-time loop execution in motor control. |
| ADC Resolution & Channels | 10-bit, up to 24 channels across two synchronizable converters - supports simultaneous current/voltage sampling in 3-phase PMSM control. |
| Flash Memory | 576 KB - sufficient for dual-bank firmware with bootloader, safety monitor, and application code in ASIL-B designs. |
| CAN Nodes / Message Objects | 6 CAN nodes, 128 message objects - enables distributed drive architecture with gateway routing between subsystems. |
| On-Chip RAM Types | 8 KB SBRAM (standby), 2 KB DPRAM (dual-port), 16 KB DSRAM, 32 KB PSRAM - isolates real-time ISR data, shared buffers, and program execution domains. |

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-48F100L AA | 100 MHz CPU clock, 768 KB Flash, identical peripheral set - higher performance but increased power consumption and thermal footprint. | Suitable for applications requiring faster FOC loop rates (>20 kHz) or larger firmware images with cryptographic libraries. | Select when >80 MHz deterministic throughput is required and thermal design accommodates +15% power draw. |
| SAK-TC275T-64F200N AC | TriCore™ 32-bit CPU, 200 MHz, 4 MB Flash, ASIL-D ready, but lacks C166 legacy compatibility and XE167-specific CAPCOM2/CCU6x register mapping. | Targets next-gen automotive ADAS and chassis control where ISO 26262 ASIL-D certification is mandatory. | Choose only for greenfield designs prioritizing future-proof safety certification over legacy code reuse or toolchain continuity. |
Compared with SAF-XE167GM-48F80L AA, the XE167HM offers higher clock speed and Flash capacity at the cost of thermal headroom, while the TC275T provides ASIL-D readiness and 32-bit scalability but requires full firmware re-architecture and new development tools.

FAQ
What is the maximum operating temperature range for SAF-XE167GM-48F80L AA?
The SAF-XE167GM-48F80L AA is rated for industrial temperature operation from –40 °C to +125 °C ambient, validated per JEDEC JESD22-A108 and qualified with 1000-cycle temperature cycling. Thermal derating begins above 105 °C case temperature, requiring heatsinking or airflow in enclosed enclosures.
Does this device support JTAG debugging in production environments?
Yes - SAF-XE167GM-48F80L AA includes full on-chip debug support via JTAG interface compliant with IEEE 1149.1, enabling boundary-scan testing, real-time trace, and non-intrusive breakpoint setting without halting peripheral operation during field diagnostics.
How is Flash memory protected against unauthorized access or corruption?
Flash protection uses three mechanisms: (1) Security bit locking preventing read-out via debug interface, (2) ECC circuitry correcting single-bit errors and detecting double-bit errors per 64-bit word, and (3) MPU-enforced write-protection zones restricting firmware updates to designated sectors only.
Can the dual ADCs be triggered simultaneously by a single CCU6x event?
Yes - the XE167GM supports hardware-synchronized start of both ADCs using a single trigger signal from any CCU6x unit, ensuring phase-aligned sampling for current reconstruction in 3-phase motor control with <10 ns skew between channels.
