Product details
Overview
SAF-XC164SM-8F40F AA from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 64 KB on-chip Flash, 2 KB DPRAM + 2 KB DSRAM + 2 KB PSRAM, and operation at 40 MHz CPU clock (25 ns instruction cycle). It integrates ASC0/ASC1 USARTs, SSC0/SSC1 synchronous serial channels, a 14-channel 10-bit ADC (2.55 μs conversion), CAPCOM2/CAPCOM6 PWM units, and GPT12E timers for motor control and industrial automation.
For engineers reviewing the SAF-XC164SM-8F40F AA datasheet, SAF-XC164SM-8F40F AA pinout, SAF-XC164SM-8F40F AA application, or SAF-XC164SM-8F40F AA equivalent, key selection criteria include Flash size (64 KB), SRAM configuration (2+2+2 KB), 40 MHz real-time performance, RoHS-compliant 64-pin TQFP package, and integrated peripheral set for deterministic embedded control.
Technical Context
The XC164SM implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions-enabling deterministic execution in real-time motor control loops. Its interrupt system supports 63 sources across 16 priority levels with 50 ns sample rate, synchronized to peripheral events via the 8-channel PEC.
On-chip peripherals include dual ASC interfaces supporting asynchronous/synchronous protocols, two high-speed SSC modules for SPI-like communication, and CAPCOM6 configured for flexible PWM generation with dead-time insertion-critical for three-phase inverter gate drive timing.

|---|---|---|---|
| SAF-XC164CS-8F40F | Same core and peripherals but lacks CAPCOM6 unit and has only CAPCOM2 (16-channel capture/compare) | No native 6-channel complementary PWM; requires external gate driver ICs for 3-phase inverters | Select when PWM complexity is low and cost sensitivity outweighs integration benefit |
| SAF-XC2267-104F80L | Enhanced C166SV2 derivative with 128 KB Flash, 16 KB RAM, and additional CAN 2.0B controller | Includes CAN interface for distributed control networks; higher memory supports larger safety stacks | Select when CAN connectivity and ASIL-B compliance are required alongside legacy XC164 software compatibility |
Compared with SAF-XC164CS-8F40F, the SAF-XC164SM-8F40F AA delivers integrated 6-channel PWM for motor drive, while versus SAF-XC2267-104F80L, it offers lower cost and smaller footprint where CAN is unnecessary-making it optimal for cost-constrained, self-contained control nodes.

FAQ
What is the maximum operating temperature range for SAF-XC164SM-8F40F AA?
The SAF-XC164SM-8F40F AA is rated for operation from −40 °C to +85 °C ambient temperature, validated per Infineon's industrial qualification standards (AEC-Q100 not applicable; intended for industrial-grade use). Thermal derating begins above 70 °C ambient depending on PCB copper area and airflow.
Does SAF-XC164SM-8F40F AA support in-system programming (ISP) via its on-chip bootloader?
Yes-the device includes an on-chip bootstrap loader accessible via ASC0 or ASC1, enabling ISP through UART using standard Intel HEX or binary formats. Bootloader activation requires specific pin strapping during reset and supports Flash erase/write without external programmer.
Can the CAPCOM6 unit generate center-aligned PWM signals with automatic dead-time insertion?
Yes-CAPCOM6 supports center-aligned PWM mode with programmable dead-time values (1–64 clock cycles) applied automatically to complementary channel pairs. Dead-time is inserted symmetrically around the center point and can be updated dynamically via register writes during runtime.
Is JTAG debug support fully compliant with IEEE 1149.1, and does it support real-time trace?
The on-chip debug support (OCDS) complies with IEEE 1149.1 for boundary scan and basic debug operations, but does not implement ETM-style real-time instruction trace. It supports hardware breakpoints, watchpoints, and real-time memory/register access-sufficient for functional validation and timing analysis in motor control loops.
