C164CL8RMCAKXQMA9

Overview

The C164CL8RMCAKXQMA9 is a 16-bit single-chip microcontroller from Infineon Technologies, part of the C164 family. It features 64KB of Mask ROM program memory and 4KB x 8 RAM. The device includes eight 10-bit analog-to-digital converters (A/D). It operates on a supply voltage range of 4.75V to 5.5V and utilizes an external oscillator type.

Feature Summary

• Integrates 64KB Mask ROM for non-volatile program storage
• Includes 4KB x 8 RAM for data processing
• Equipped with eight 10-bit A/D converters for signal acquisition

Applications

• Industrial control systems requiring 16-bit processing
• Automotive electronics applications
• Embedded systems utilizing analog sensor inputs

Procurement Notes

Verify the specific suffix KXQMA9 against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts for the 80MQFP package. Confirm that the external oscillator requirement aligns with system clock design constraints before procurement.

Selection Notes

Select this component when a 16-bit architecture with integrated high-resolution ADCs is required. The external oscillator specification necessitates careful clock circuit design. Consider the Mask ROM limitation if frequent firmware updates are needed, as it does not support in-system reprogramming like Flash variants.

Part Context

This microcontroller belongs to the Infineon C164 series, designed for high-performance embedded applications. The C164CL variant specifically targets cost-sensitive applications while maintaining robust peripheral sets. It represents a mature technology platform widely used in established industrial and automotive designs.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing with newer Infineon families such as XC2000 or Aurix may be necessary for modern replacements, subject to architectural compatibility.
