Infineon Technologies SAF-XC164S-32F40F BB

Overview

SAF-XC164S-32F40F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 256 KB on-chip Flash, 12 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and operation up to 40 MHz CPU clock (25 ns instruction cycle). It integrates dual ASC/SSC serial interfaces, a 14-channel 10-bit ADC (2.55 µs conversion), CAPCOM6 PWM unit, and real-time clock - deployed in industrial motor control and embedded power electronics.

For engineers reviewing the SAF-XC164S-32F40F BB datasheet, SAF-XC164S-32F40F BB pinout, SAF-XC164S-32F40F BB application, or SAF-XC164S-32F40F BB equivalent, key selection criteria include Flash access timing at 40 MHz, PEC-driven DMA with 24-bit addressing, interrupt latency down to 50 ns, and RoHS-compliant 100-pin TQFP package with 0.5 mm pitch.

Technical Context

The XC164S-32F40F BB implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions - enabling deterministic real-time execution in motor commutation loops. Its peripheral event controller (PEC) supports single-cycle data transfers across the full 16 MB linear address space using 24-bit pointers.

On-chip clock generation includes a programmable PLL (1:0.15 to 1:10) and prescaler (1:1 to 60:1), allowing precise synchronization of ADC sampling, PWM edge placement, and serial interface baud rates. The 14-channel ADC supports programmable resolution (8/10-bit) and conversion times as low as 2.55 µs.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time for SAF-XC164S-32F40F BB?

The SAF-XC164S-32F40F BB operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution. This assumes proper Flash wait-state configuration (IMBCTRL.WSFLASH) to match the 40 MHz access timing requirement specified in Section 4.4.2 of the datasheet.

Does SAF-XC164S-32F40F BB support JTAG-based debugging and in-system programming?

Yes, the device includes On-Chip Debug Support (OCDS) compliant with IEEE 1149.1 JTAG, enabling full boundary-scan testing, non-intrusive breakpoints, register and memory inspection, and in-system Flash programming without requiring a debug monitor or boot ROM intervention.

How many analog input channels does the integrated ADC support, and what are its key timing specifications?

The integrated ADC supports 14 analog input channels with programmable resolution (8-bit or 10-bit). At 10-bit resolution, minimum conversion time is 2.55 µs; at 8-bit, it reduces to 2.15 µs. Linearity is ±1 LSB INL, and sampling is triggerable by timer, PWM, or external event.

What external memory interface capabilities does SAF-XC164S-32F40F BB provide?

The device supports up to 12 MB of external address space with configurable bus width (8/16-bit data), multiplexed/demultiplexed modes, four programmable chip-select signals, and programmable timing parameters per address range - enabling direct connection to SRAM, Flash, or FPGA peripherals without glue logic.
