Overview
The 80C166MT3DDBXUMA1 is a legacy 16-bit microcontroller from Infineon Technologies, belonging to the C166 family. It features a high-speed CPU with a clock frequency of up to 40 MHz. The device is housed in a DRex package and operates as a ROMless MCU. It supports external oscillators and includes integrated peripherals such as PWM and WDT. The component is designed for embedded applications requiring robust 16-bit processing capabilities within the specified industrial temperature range.
Feature Summary
- High-speed 16-bit CPU architecture capable of operating at frequencies up to 40 MHz
- ROMless memory configuration allowing flexible code storage solutions
- Integrated peripheral set including Pulse Width Modulation (PWM) and Watchdog Timer (WDT)
- Surface-mount packaging optimized for automated assembly processes
Applications
- Industrial motor control systems
- Automotive electronic modules
- Embedded control units requiring 16-bit processing
- Legacy system maintenance and replacement
Procurement Notes
Verify component authenticity through authorized distributors due to its status as a legacy product. Confirm package integrity and pin alignment prior to integration. Check for obsolescence notices or end-of-life declarations from Infineon. Ensure compatibility with existing board layouts and thermal management requirements. Validate supply chain sources to avoid counterfeit components.
Selection Notes
Select this component when a proven 16-bit architecture with 40 MHz performance is required for legacy compatibility. Consider it for designs needing integrated PWM and WDT without external logic. Evaluate space constraints against the DRex package dimensions. Assess long-term availability risks associated with discontinued series before finalizing the bill of materials.
Part Context
This microcontroller belongs to the Infineon C166 family, a well-established line of 16-bit MCUs widely used in automotive and industrial sectors. The 80C166 variant specifically targets applications demanding reliable real-time control. Its ROMless nature distinguishes it from masked ROM counterparts, offering design flexibility for firmware updates and prototyping phases.
Replacement Considerations
Direct substitutes may be limited due to the legacy status. Review Infineon's migration guides for newer C16x or XMC families. Verify pin-to-pin compatibility if replacing on existing boards. Consult official documentation for architectural differences in instruction sets and peripheral configurations.
