The part is intended for legacy industrial control, motor drive, and automation applications where the C166 architecture is already qualified in the BOM. Key features include 47 general-purpose I/O lines, a 14-channel 8/10-bit SAR ADC, serial interfaces (ASC, SPI, SSC, UART/USART), PWM outputs, and a watchdog timer. ## Supply voltage and package — board-level fit A dedicated regulator or LDO is needed if the rest of the board runs at 3.3 V. The device is surface-mount only; the exact package footprint is not listed here, but the 'TM16' suffix in the order code typically indicates a TQFP-16×16 body with 144 pins — verify against the official datasheet before laying out the board. The SAFXC164TM16F20FBA is listed as Active by Infineon. For a BOM line that already qualifies this part, there is no immediate urgency to find a replacement.","metaTitle":"Infineon SAFXC164TM16F20FBA 16-bit C166SV2 MCU, 40 MHz","metaDescription":"Infineon SAFXC164TM16F20FBA 16-bit C166SV2 MCU, 40 MHz, 47 I/O, Flash, -40 to 85°C.

The C166SV2 core typically uses a JTAG or DAP (Device Access Port) interface, not the ARM SWD that J-Link natively supports. A dedicated C166 debugger (e.g., Infineon DAS-based adapter or a third-party tool with C166 support) is recommended. Confirm with the official datasheet before ordering programming hardware."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/SAFXC164TM16F20FBA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/SAFXC164TM16F20FBA when reusing this data.
