Infineon Technologies SAF-XC164TM-8F40FAA

Overview

SAF-XC164TM-8F40FAA 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), and CAPCOM2 capture/compare unit. Used in industrial motor control and embedded power conversion systems.

For engineers reviewing the SAF-XC164TM-8F40FAA datasheet, SAF-XC164TM-8F40FAA pinout, SAF-XC164TM-8F40FAA application, or SAF-XC164TM-8F40FAA equivalent, key selection criteria include Flash size (64 KB), SRAM configuration (2+2+2 KB), real-time peripheral set (GPT12E, RTC, watchdog), and TQFP-64 RoHS-compliant packaging for thermal and layout-constrained designs.

Technical Context

The SAF-XC164TM-8F40FAA implements the C166SV2 16-bit CPU with 5-stage pipeline, enabling single-cycle execution of most instructions and 1-cycle 16×16 multiplication. Its interrupt system supports 16 priority levels and up to 63 sources with 50 ns sample rate, coordinated via Peripheral Event Controller (PEC) for zero-software-latency data transfers.

On-chip peripherals include a 14-channel A/D converter with programmable 8-/10-bit resolution and sub-3 µs conversion time, dual ASC interfaces supporting asynchronous/synchronous modes, and two high-speed SSC channels for SPI-like master/slave communication. Clock generation uses an internal PLL configurable from 1:0.15 to 1:10.

FAQ

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

The SAF-XC164TM-8F40FAA operates at a maximum CPU clock of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing is guaranteed under specified VDD (4.5–5.5 V) and temperature (-40 to +85 °C) conditions per the 2007 datasheet revision V1.2.

Does this microcontroller support in-circuit debugging without halting real-time operation?

Yes - it includes On-Chip Debug Support (OCDS) accessible via JTAG (TCK/TMS/TDO/TDI pins), allowing non-intrusive breakpoints, register inspection, and memory read/write while peripherals continue running. This is confirmed in Section 3.4 of the V1.2 datasheet.

How many analog input channels does the integrated ADC support, and what is its fastest conversion time?

The device integrates a 14-channel A/D converter with programmable 8-bit or 10-bit resolution. At 10-bit mode, the minimum conversion time is 2.55 µs; at 8-bit mode, it reduces to 2.15 µs - both values measured under standard VDD and temperature conditions per Section 4.3.

Is the SAF-XC164TM-8F40FAA pin-compatible with other XC164TM derivatives in the same package?

Yes - all XC164TM derivatives in the 64-pin TQFP package (including -4F, -8F, and -16F variants) share identical pinouts and electrical characteristics. Function allocation (e.g., ADC channel mapping, CAPCOM2 pin assignment) remains consistent across derivatives per Table 1 and Section 2.1 of the datasheet.
