C161KLM3VHAFXUMA1

Overview

The C161KLM3VHAFXUMA1 is a 16-bit microcontroller from the Infineon C166 family, featuring a high-performance CPU with a 4-stage pipeline. 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 contains 1 KByte of on-chip internal RAM (IRAM) and utilizes an 80-pin MQFP package.

Feature Summary

• Features a 16-bit CPU architecture with a 4-stage instruction pipeline for efficient processing.
• Includes an external bus controller supporting multiplexed or demultiplexed memory access modes.
• Integrates multiple peripheral modules including General Purpose Timers and serial communication channels.

Applications

• Cost-sensitive embedded control systems
• Industrial automation applications
• Automotive electronic subsystems

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and delivery format. Confirm that the 3.0 V to 3.6 V operating voltage aligns with system power requirements. Check current product status as legacy components may have limited availability.

Selection Notes

Select this component when a 16-bit C166 core is required with low-voltage operation. Ensure the design accommodates the 1 KByte IRAM limitation compared to higher-capacity derivatives. Verify that the 20 MHz clock speed meets the application's timing constraints.

Part Context

This part belongs to the C161K/O derivative group within the broader C166 microcontroller family. It shares architectural similarities with other variants but is distinguished by its specific voltage range and memory configuration. The 'ROMless' designation indicates it requires external program memory.

Replacement Considerations

Consult the official C161K/O Derivative Synopsis table for compatible alternatives. Consider the C161O series if additional internal RAM or chip select signals are necessary. Verify pin compatibility before substituting with other MQFP packages in the same family.
