Procurement Notes
Verify the specific ordering suffix against the official Infineon Product Catalog Microcontrollers to confirm package type and delivery format. Ensure the selected derivative matches the required operating voltage and temperature range specifications before procurement.
Selection Notes
Select this component when a ROMless configuration with 2 KBytes of RAM is required for the C166 architecture. Confirm that the 3.0 V to 3.6 V supply voltage range aligns with the system power design. Verify the need for five timer units and four chip-select signals available in the C161O variant.
Part Context
This part belongs to the C161K/O derivative series within the broader C166 Family of single-chip microcontrollers. It shares architectural similarities with other C161 variants but is distinguished by its specific memory size, clock speed, and low-voltage operation capabilities.
Replacement Considerations
Consult the official cross-reference documentation for compatible derivatives. Verify pin compatibility and electrical specifications when substituting with other C161O variants or newer generations of the C166 family.
