Infineon Technologies SAF-XC164N-8F40FBB

Overview

SAF-XC164N-8F40FBB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, operating at 40 MHz CPU clock with 25 ns instruction cycle time. It integrates 64 Kbytes Flash program memory, 2 Kbytes dual-port RAM, and on-chip peripherals including two ASC/SSC serial interfaces, CAPCOM1/2, CAPCOM6, GPT12E timer, RTC, and PLL-based clock generation. It targets real-time motor control and industrial embedded systems requiring deterministic interrupt response down to 50 ns.

For engineers reviewing the SAF-XC164N-8F40FBB datasheet, SAF-XC164N-8F40FBB pinout, SAF-XC164N-8F40FBB application, or SAF-XC164N-8F40FBB equivalent, this page delivers verified technical context, package mapping, functional pin roles, and validated alternative options for industrial motion control, power conversion, and automotive body electronics design.

Technical Context

The SAF-XC164N-8F40FBB implements the C166SV2 16-bit RISC-like CPU with five-stage pipeline, supporting single-cycle 16×16 multiply and 21-cycle 32/16 divide. Its interrupt system provides 16 priority levels and up to 75 sources, with sample rate as low as 50 ns - critical for high-speed PWM synchronization in motor drives.

On-chip peripherals include two 16-channel CAPCOM units (12 I/O pins), a dedicated CAPCOM6 unit for flexible PWM generation (3/6 capture/compare channels + 1 compare channel), and a 5-timer GPT12E unit. Clock generation uses an internal PLL configurable from 1:0.15 to 1:10, enabling precise 40 MHz operation from lower-frequency crystals.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The SAF-XC164N-8F40FBB operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution. This timing is achieved using the on-chip PLL with configurable multiplication factors (1:0.15 to 1:10), and is validated under industrial temperature range (−40 °C to +85 °C) per datasheet Section 4.3.

Does this microcontroller support JTAG-based debugging?

Yes - the SAF-XC164N-8F40FBB includes full On-Chip Debug Support (OCDS) accessible via standard JTAG interface (TCK, TMS, TDI, TDO, TRST). It supports real-time trace, hardware breakpoints, and non-intrusive debugging without CPU halting, as documented in Section 3.5 of the V1.2 datasheet.

How many capture/compare channels does CAPCOM6 provide?

CAPCOM6 provides either 3 or 6 capture/compare channels plus 1 dedicated compare channel, depending on configuration mode. This flexibility enables complex PWM topologies such as three-phase center-aligned PWM with dead-time insertion and fault protection, as defined in Section 3.7 of the datasheet.

Is the 100-pin TQFP package RoHS compliant?

Yes - the SAF-XC164N-8F40FBB uses a "Green TQFP" package specified in Section 5.1 of the datasheet, explicitly labeled RoHS compliant with lead-free terminations and halogen-free molding compound, meeting EU Directive 2011/65/EU requirements.
