Product details
Overview
SAF-XC164TM-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, and 2 KB PSRAM. It operates at 40 MHz CPU clock (25 ns instruction cycle), supports 14-channel 10/8-bit ADC with 2.55 µs conversion time, and integrates ASC0/ASC1 and SSC0/SSC1 serial interfaces for industrial motor control and power electronics applications.
For engineers reviewing the SAF-XC164TM-8F40F AA datasheet, SAF-XC164TM-8F40F AA pinout, SAF-XC164TM-8F40F AA application, or SAF-XC164TM-8F40F AA equivalent, key selection considerations include Flash size (64 KB), dual-port RAM architecture, real-time interrupt latency (50 ns min), CAPCOM2 timer resolution, and RoHS-compliant 64-pin TQFP package compatibility with legacy C166 toolchains.
Technical Context
The XC164TM implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and background 32/16 division in 21 cycles. Its memory subsystem includes separate address spaces for code and data within a 16 MB linear map, with on-chip SRAM banks supporting fast context switching via two local register banks.
Peripheral integration centers on deterministic real-time control: the 16-channel CAPCOM2 unit enables precise PWM generation and capture with programmable dead-time insertion; the GPT12E timer provides five independent timers with reload and prescaler support; and the 14-channel A/D converter offers selectable 8- or 10-bit resolution with configurable sampling windows aligned to timer events.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-8F40F | Same core and peripheral set but uses C166S V2 core (not SV2); lacks CAPCOM2 dead-time insertion and PEC channel count | Lower-cost variant for less demanding motor control where precise PWM dead-time is not required | Select only if legacy software compatibility with XC164CS toolchain is mandatory and advanced timer features are unused |
| SAF-XC2267-104F80L | 32-bit TriCore™ core, 80 MHz, 1 MB Flash, integrated CAN FD and Ethernet MAC - no direct pin or code compatibility | Next-generation replacement requiring full firmware rewrite; suited for safety-critical automotive ECUs needing ASIL-B compliance | Choose when migrating from 16-bit to 32-bit architecture with expanded connectivity and functional safety requirements |
Compared with SAF-XC164CS-8F40F, the SAF-XC164TM-8F40F delivers deterministic dead-time control and higher PEC bandwidth for tighter motor control loops; versus SAF-XC2267-104F80L, it offers lower power, smaller footprint, and proven qualification for cost-sensitive industrial drives without safety certification overhead.
