Product details
Overview
SAF-XC164N-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, CAPCOM6 for PWM generation, GPT12E timer, RTC, and JTAG-based OCDS debug support. Used in industrial motor control and embedded power conversion systems requiring deterministic real-time response.
For engineers reviewing the SAF-XC164N-32F40F BB datasheet, SAF-XC164N-32F40F BB pinout, SAF-XC164N-32F40F BB application, or SAF-XC164N-32F40F BB equivalent, key selection criteria include Flash access timing at 40 MHz, 100-pin TQFP package compatibility, interrupt latency down to 50 ns, and peripheral event controller (PEC) support for zero-overhead DMA transfers.
Technical Context
The SAF-XC164N-32F40F BB implements a 5-stage pipelined C166SV2 CPU with single-cycle 16×16 multiply, 21-cycle 32/16 divide, and MAC instructions - enabling efficient digital control loop execution. Its memory subsystem includes separate 2 KB dual-port RAM for concurrent CPU/peripheral access and 6 KB program/data SRAM for code overlay or stack expansion.
Peripheral integration centers on deterministic real-time I/O: two 16-channel CAPCOM units with input capture and output compare, CAPCOM6 with dedicated PWM channels, GPT12E with five independent timers, and two ASC (UART-like) plus two SSC (SPI-like) interfaces - all interrupt- or PEC-driven with configurable priority levels across 75 sources.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-32F40F | Same C166SV2 core, identical Flash/SRAM, but uses XC164CS pinout and lacks CAPCOM6 unit | Not suitable for applications requiring flexible PWM generation (e.g., motor phase control) | Select only if CAPCOM6 is unused and legacy board layout compatibility is required |
| SAF-XC2267M-104F80L | Successor 32-bit TriCore™ core, 80 MHz, 512 KB Flash, 64 KB RAM, integrated CAN 2.0B | Requires software migration; adds CAN connectivity but increases BOM cost and power | Choose for new designs needing CAN or higher compute throughput; not drop-in compatible |
Compared with SAF-XC164CS-32F40F, the SAF-XC164N-32F40F BB provides essential CAPCOM6 PWM capability for motor control, while versus SAF-XC2267M-104F80L, it offers lower cost and proven qualification for legacy industrial deployments without CAN requirement.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The SAF-XC164N-32F40F BB operates at a maximum CPU clock of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution. This timing assumes proper Flash wait-state configuration (WSFLASH bits in IMBCTRL register) and stable 3.3 V ±5% supply voltage per datasheet Section 4.3.2.
Does this microcontroller support in-system programming (ISP) via JTAG?
Yes - the SAF-XC164N-32F40F BB supports full on-chip debug via JTAG (TCK/TDI/TDO/TMS), including flash programming, breakpoint setting, and real-time variable inspection. The on-chip bootstrap loader also enables UART-based ISP using ASC0, as documented in Section 3.5 and the Application Note AP32063.
How many independent PWM channels does CAPCOM6 provide, and what are their configurations?
CAPCOM6 provides three dedicated capture/compare channels and one additional compare channel, supporting center-aligned or edge-aligned PWM with programmable dead-time insertion. All six output pins (CC60–CC65) are individually configurable for PWM, capture, or general I/O, as defined in Section 3.7 of the datasheet.
Is the 100-pin TQFP package RoHS-compliant and lead-free?
Yes - the SAF-XC164N-32F40F BB is packaged in a green (halogen-free, RoHS-compliant) 100-pin TQFP with lead-free terminations and 0.5 mm pitch, certified per JEDEC J-STD-020D and Infineon's Material Declaration Sheet MDS-2006-08-001.
