Product details
Overview
SAF-XC164LM-4F20F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 32 KB on-chip Flash, 2 KB dual-port RAM, and 2 KB program/data SRAM. It operates at up to 40 MHz CPU clock (25 ns instruction cycle), supports 16-priority-level interrupts with 50 ns sample rate, and integrates ASC0/ASC1 and SSC0/SSC1 serial interfaces for industrial motor control systems.
For engineers reviewing the SAF-XC164LM-4F20F AA datasheet, SAF-XC164LM-4F20F AA pinout, SAF-XC164LM-4F20F AA application, or SAF-XC164LM-4F20F AA equivalent, key selection criteria include Flash size (32 KB), real-time interrupt latency (50 ns), integrated CAPCOM2 unit for PWM generation, and TQFP-64 RoHS-compliant packaging for space-constrained embedded designs.
Technical Context
The XC164LM implements a 5-stage pipeline C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiplication, and background 32/16 division in 21 cycles. Its memory subsystem includes linear 16 MB address space, on-chip DPRAM for concurrent CPU/peripheral access, and Flash configurable for code or data storage.
Peripheral integration centers on deterministic real-time control: CAPCOM2 provides 16-channel capture/compare with dead-time insertion; GPT12E offers five timers with reload and prescaler support; RTC runs independently from main oscillator; and PEC enables single-cycle DMA transfers using 24-bit pointers across full address space.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-4F20F | Same C166SV2 core but lacks CAPCOM2 unit and has only 16 KB Flash | Not suitable for motor control requiring hardware PWM generation | Select only for simpler I/O-centric tasks where Flash and peripheral count are reduced |
| XC2267M-40F66L | Successor derivative with 64 KB Flash, enhanced GPT12E, and CAN 2.0B controller | Requires CAN bus integration and higher code density; not pin-compatible | Choose when upgrading legacy designs needing CAN and extended memory without changing PCB layout |
Compared with SAF-XC164CS-4F20F, the SAF-XC164LM-4F20F AA adds CAPCOM2 and doubles Flash capacity for complex control algorithms; versus XC2267M-40F66L, it trades CAN capability and larger memory for lower cost and proven field reliability in mature industrial deployments.

FAQ
What is the maximum operating temperature range for SAF-XC164LM-4F20F AA?
The SAF-XC164LM-4F20F AA is rated for operation from –40 °C to +85 °C ambient temperature. This range is validated per Infineon's qualification standards and applies to all electrical parameters in the datasheet. Thermal derating is not required within this envelope, and the TQFP package's θJA of 40 K/W ensures safe junction temperatures under typical industrial airflow conditions.
Does SAF-XC164LM-4F20F AA support in-system programming of its Flash memory?
Yes, SAF-XC164LM-4F20F AA supports in-system programming (ISP) via its on-chip bootstrap loader and JTAG interface. The 32 KB Flash is organized into sectors with individual lock bits, enabling selective reprogramming without erasing the entire memory. ISP requires no external high-voltage supply and operates at standard VDD levels (3.0–5.5 V), making it suitable for field firmware updates.
Can SAF-XC164LM-4F20F AA generate complementary PWM signals with programmable dead time?
Yes, the integrated CAPCOM2 unit provides 16-channel capture/compare functionality with hardware-configurable dead-time insertion between complementary outputs. Dead time is set via dedicated registers and enforced at the pin level without CPU intervention, ensuring reliable prevention of shoot-through in half-bridge and 3-phase inverter topologies.
Is there a hardware watchdog timer, and how is it configured?
SAF-XC164LM-4F20F AA includes a programmable watchdog timer (WDT) with independent oscillator and timeout period adjustable from 16 ms to 2 s. Configuration is performed through WDTCON register bits; the WDT can be enabled/disabled and serviced via software write sequence. An optional oscillator watchdog monitors the main crystal oscillator and triggers reset if oscillation fails.
