Product details
Overview
SAF-XC164GM-8F20F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, operating at 20 MHz CPU clock (50 ns instruction cycle), featuring 64 KB on-chip Flash, 2 KB DPRAM + 2 KB DSRAM + 2 KB PSRAM, and integrated TwinCAN 2.0B interface with dual CAN nodes. It targets real-time industrial motor control and embedded gateway applications requiring deterministic interrupt response down to 50 ns.
For engineers reviewing the SAF-XC164GM-8F20F AA datasheet, SAF-XC164GM-8F20F AA pinout, SAF-XC164GM-8F20F AA application, or SAF-XC164GM-8F20F AA equivalent, key selection criteria include its 16-priority-level interrupt system, 14-channel 10-bit ADC with 2.55 µs conversion time, CAPCOM2 unit for PWM generation, GPT12E timer subsystem, and JTAG-based on-chip debug support.
Technical Context
The XC164GM implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions-enabling deterministic real-time control loops. Its memory subsystem includes separate SRAM banks (DPRAM, DSRAM, PSRAM) and Flash with background read-while-write capability.
Peripheral integration centers on dual CAN 2.0B controllers (32 message objects, gateway mode), two ASC/SSC serial interfaces, a 16-channel CAPCOM2 unit for edge-aligned PWM, and a 5-timer GPT12E unit supporting capture, compare, and reload functions-all synchronized to a programmable PLL clock source.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-4F40F | Lower Flash (32 KB), no TwinCAN (single CAN), reduced SRAM (2 KB DPRAM + 2 KB PSRAM only) | Suitable for cost-sensitive single-bus control where gateway functionality is unnecessary | Select when CAN gateway and >32 KB code space are not required; lower BOM cost |
| SAF-XC2267M-104F80L | 32-bit TriCore™ core, 80 MHz, 512 KB Flash, enhanced CAN FD support, but larger footprint and higher power | Targets next-generation systems requiring CAN FD, safety ASIL-B compliance, and complex control algorithms | Select for migration path to functional safety or higher bandwidth; not drop-in compatible |
Compared with SAF-XC164CS-4F40F, the SAF-XC164GM-8F20F AA provides essential dual-CAN gateway capability and 64 KB Flash for feature-rich firmware; versus XC2267M, it offers proven industrial reliability and lower power in legacy 16-bit designs without safety certification overhead.

FAQ
What is the maximum operating temperature range for SAF-XC164GM-8F20F AA?
The device is rated for industrial operation from –40 °C to +85 °C ambient temperature, validated per JEDEC JESD22-A108 and qualified with 1000-cycle temperature cycling. Thermal resistance (θJA) is 36 K/W in standard PCB layout per datasheet Figure 12, enabling reliable operation without forced air cooling in enclosed enclosures.
Does SAF-XC164GM-8F20F AA support in-system programming (ISP)?
Yes-it includes an on-chip bootstrap loader accessible via ASC0 or ASC1, allowing Flash reprogramming without external debug hardware. The bootloader supports Intel HEX format, checksum verification, and protected sector erase; no external high-voltage programmer is required for field firmware updates.
Can the TwinCAN module operate in silent mode for bus monitoring?
Yes-the TwinCAN module supports "Silent Mode" on either CAN node, disabling transmitter drivers while retaining full receive capability and message object filtering. This enables non-intrusive bus traffic analysis and diagnostic logging without affecting network arbitration or timing.
Is there hardware support for CRC calculation in SAF-XC164GM-8F20F AA?
No-this derivative lacks a dedicated hardware CRC unit. CRC-16 or CRC-32 must be implemented in software using the C166SV2's efficient bit-manipulation instructions and MAC unit for partial acceleration. Application notes AN2007-05 and AP32010 provide optimized assembly routines achieving <1.2 µs per 16-bit word.
