C161OLM3VHAFXUMA1

Overview

The Infineon C161OLM3VHAFXUMA1 is a 16-bit single-chip microcontroller from the C166 family, featuring a ROMless architecture with 2 KBytes of internal RAM. It operates at a maximum frequency of 20 MHz and supports a supply voltage range of 3.0 V to 3.6 V. The device utilizes an 80-pin MQFP package and provides up to 63 general-purpose I/O lines.

Feature Summary

• High-performance 16-bit CPU with a 4-stage pipeline
• Integrated External Bus Controller for flexible memory interfacing
• Programmable Watchdog Timer and multiple interrupt sources

Applications

• Cost-sensitive embedded control systems
• Industrial automation controllers
• Automotive electronic modules

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and delivery format. Confirm that the component meets RoHS compliance standards required for your manufacturing process. Ensure compatibility with existing development tools such as C-compilers and emulators before procurement.

Selection Notes

Select this derivative when a 3.3 V operating voltage is required alongside 20 MHz performance. The ROMless configuration allows for external program memory expansion. Verify that the 2 KByte IRAM capacity meets application stack and variable storage requirements.

Part Context

This component belongs to the C161K/O series within the broader C166 microcontroller family. It shares architectural similarities with other derivatives but is distinguished by its specific voltage rating and lack of on-chip mask ROM. It serves as a versatile solution for applications needing external memory flexibility.

Replacement Considerations

Consult official cross-reference lists for compatible variants. Derivatives like SAB-C161O-LM3V offer similar functionality but may differ in package or delivery specifications. Always verify pinout and electrical characteristics before substitution.
