C164CI8RMCAKXUMA4

Overview

The Infineon C164CI8RMCAKXUMA4 is a 16-bit microcontroller belonging to the C166 family, designed for cost-sensitive applications. It features a high-performance CPU with a 4-stage pipeline and an instruction cycle time of 80 ns at a 25 MHz clock frequency. The device integrates up to 64 KBytes of on-chip program memory, which can be implemented as either Mask ROM or One-Time Programmable (OTP) memory. Additional on-chip resources include 2 KBytes of Internal RAM (IRAM) and 2 KBytes of Extension RAM (XRAM). The MCU supports a 16-priority-level interrupt system with 32 sources and includes peripheral modules such as an 8-channel 10-bit A/D converter and an 8-channel General Purpose Capture/Compare Unit.

Feature Summary

• High-performance 16-bit CPU architecture with a 4-stage pipeline and single-cycle context switching support.
• Integrated clock generation capabilities via an on-chip Phase-Locked Loop (PLL) with multiple frequency factors.
• Peripheral Event Controller (PEC) providing 8-channel interrupt-driven single-cycle data transfer facilities.
• Enhanced boolean bit manipulation facilities and additional instructions supporting high-level languages.

Applications

• Cost-sensitive automotive electronic systems
• Industrial control applications requiring robust 16-bit processing
• Embedded systems utilizing OTP memory for fixed firmware requirements

Procurement Notes

Verify the specific memory configuration, as the C164CI derivative series supports both Mask ROM and OTP variants. Confirm that the ordering suffix corresponds to the required memory type and package specifications. Ensure compatibility with existing development tools for the C166 family, including compilers and debuggers. Check for end-of-life status or alternative recommendations from the manufacturer if long-term supply is critical for the project timeline.

Selection Notes

Select this component when a balance between high CPU performance and low cost is required for embedded control tasks. The C164CI series is suitable for applications needing extensive I/O capabilities and integrated analog peripherals like the 10-bit ADC. Consider the available on-chip memory sizes against application code and data storage needs. Evaluate the interrupt handling capabilities if real-time response to multiple external events is necessary.

Part Context

This microcontroller is part of the broader Infineon C166 family, which provides a scalable range of 16-bit solutions. The C164CI derivatives are specifically optimized for cost-sensitive markets while maintaining the core architectural benefits of the family. This lineage ensures software compatibility with other members of the C166 ecosystem, facilitating migration and reuse of code across different product tiers within automotive and industrial sectors.

Replacement Considerations

Consult official Infineon documentation for direct pin-to-pin replacements or functional equivalents within the C166 family. Verify memory options and package availability for any substitute part numbers before implementation.
