Product details
Overview
SAF-XC164SM-4F40F 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 40 MHz CPU clock (25 ns instruction cycle), supports 14-channel 10-bit ADC with 2.55 µs conversion time, and integrates ASC0/ASC1 and SSC0/SSC1 serial interfaces for industrial motor control systems.
For engineers reviewing the SAF-XC164SM-4F40F AA datasheet, SAF-XC164SM-4F40F AA pinout, SAF-XC164SM-4F40F AA application, or SAF-XC164SM-4F40F AA equivalent, key selection criteria include Flash size (32 KB), dual-port RAM configuration, real-time interrupt latency (50 ns sample rate), and TQFP-64 RoHS-compliant packaging for embedded motion control designs.
Technical Context
The XC164SM-4F40F implements the C166SV2 16-bit CPU core with a 5-stage pipeline, enabling single-cycle execution of most instructions and 1-cycle 16×16 multiplication. Its memory subsystem includes 32 KB Flash (program), 2 KB DPRAM (data sharing between CPU and peripherals), and 2 KB PSRAM (code/data overlay support).
Peripheral integration centers on deterministic real-time control: CAPCOM2 (16-channel capture/compare), CAPCOM6 (flexible PWM generation), GPT12E (5-timer unit), and a 14-channel A/D converter with programmable resolution (8/10-bit) and conversion timing down to 2.55 µs - all synchronized via the Peripheral Event Controller (PEC) for zero-software-latency data transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit real-time microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-4F40F | Same C166SV2 core and pinout, but lacks CAPCOM6 unit and has reduced peripheral set (no SSC) | Suitable for simpler timer/PWM-only applications without complex encoder or synchronous serial needs | Select when CAPCOM6 and SSC interfaces are unused; lower cost and identical footprint |
| SAF-XC167CI-4F40F | Enhanced C166SV2 derivative with 64 KB Flash, additional CAPCOM units, and extended interrupt vector table | Required for larger firmware images or multi-axis coordination where extra timers and memory are essential | Select when future firmware expansion or dual-motor control is planned; same TQFP-64 package |
Compared with SAF-XC164CS-4F40F, the SAF-XC164SM-4F40F adds CAPCOM6 and SSC for advanced PWM and encoder support; versus SAF-XC167CI-4F40F, it trades Flash capacity and peripheral count for lower BOM cost while retaining full real-time interrupt and ADC performance.
