Infineon Technologies SAF-XC164S-8F40F BB

Overview

SAF-XC164S-8F40F BB 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 KB on-chip Flash, 2 KB DPRAM, 2 KB DSRAM, 2 KB PSRAM, a 14-channel 10/8-bit ADC (2.55 µs min conversion), CAPCOM1/2 and CAPCOM6 PWM units, two ASC and two SSC serial interfaces, and real-time clock functionality. It targets motor control and industrial embedded systems requiring deterministic timing and mixed-signal integration.

For engineers reviewing the SAF-XC164S-8F40F BB datasheet, SAF-XC164S-8F40F BB pinout, SAF-XC164S-8F40F BB application, or SAF-XC164S-8F40F BB equivalent, key selection criteria include Flash size vs. RAM partitioning, 40 MHz real-time execution capability, CAPCOM6-based PWM flexibility, ASC/SSC dual-serial support, and TQFP-100 RoHS-compliant packaging for high-pin-count industrial control.

Technical Context

The SAF-XC164S-8F40F BB implements a 5-stage pipelined C166SV2 CPU core with zero-cycle jumps, 1-cycle 16×16 multiply, and 21-cycle 32/16 divide - enabling deterministic real-time loop execution in motor control firmware. Its peripheral event controller (PEC) supports 8-channel interrupt-driven DMA with 24-bit addressing across the full 16 MB linear space.

On-chip clock generation includes a programmable PLL (1:0.15 to 1:10) and prescaler (1:1 to 60:1), allowing precise 40 MHz core operation from external crystal or oscillator inputs. The A/D converter features programmable resolution (8- or 10-bit) and sample-rate down to 2.55 µs, synchronized to timer events via CAPCOM triggers.

FAQ

What is the maximum operating temperature range for SAF-XC164S-8F40F BB?

The SAF-XC164S-8F40F BB is rated for operation from −40 °C to +85 °C ambient temperature, validated per Infineon's industrial qualification standards. This range supports deployment in enclosed motor drive cabinets and outdoor HVAC enclosures without forced cooling.

Does SAF-XC164S-8F40F BB support JTAG-based debugging in production firmware?

Yes - the device includes full On-Chip Debug Support (OCDS) via standard JTAG interface, enabling non-intrusive breakpoints, register inspection, and flash programming even in final firmware builds, provided TRST and TDI/TDO/TCK/TMS pins are accessible on the PCB.

Can the internal PLL generate a stable 40 MHz clock from a 10 MHz crystal?

Yes - the on-chip PLL supports multiplication factors from 1:0.15 to 1:10; a 10 MHz crystal with ×4 multiplication yields exactly 40 MHz core clock, meeting the device's specified timing performance with documented jitter characteristics in the datasheet AC parameters section.

Is the 14-channel ADC capable of simultaneous sampling across all channels?

No - the ADC is a single successive-approximation unit with multiplexed inputs; it performs sequential conversions per channel. However, the PEC can autonomously trigger and store results from up to 14 channels in sequence without CPU involvement, achieving effective multi-channel acquisition within one timer period.
