C164CI8RMCAKXUMB1

Overview

The Infineon C164CI8RMCAKXUMB1 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 speed. The device integrates up to 64 KBytes of on-chip program memory, specifically One-Time Programmable (OTP) in this variant, alongside 2 KBytes of internal RAM and 2 KBytes of extension RAM. Peripheral capabilities include an 8-channel 10-bit A/D converter, an 8-channel CAPCOM2 unit, and a Peripheral Event Controller supporting single-cycle data transfer.

Feature Summary

• High-performance 16-bit CPU architecture with four-stage pipeline processing
• Integrated on-chip PLL for flexible clock generation
• Peripheral Event Controller enabling interrupt-driven single-cycle data transfers
• Comprehensive peripheral set including ADC and capture/compare units

Applications

• Cost-sensitive industrial control systems
• Automotive electronic modules
• General-purpose embedded applications requiring 16-bit processing

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm specific OTP programming requirements and voltage levels prior to implementation. Ensure compliance with RoHS standards as indicated by manufacturer specifications. Review latest datasheets for any updates regarding pin compatibility or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when a balance between high CPU performance and low system cost is required. The C164CI series offers enhanced I/O capabilities and sufficient on-chip memory for many standalone applications. Consider the OTP memory type if mass production programming infrastructure is available, as it eliminates the need for external mask ROM programming services.

Part Context

This microcontroller is part of the broader C166 family, which provides a scalable range of 16-bit solutions. The C164CI derivatives are positioned as entry-level options within this family, focusing on essential features like the PEC and standard peripherals while maintaining the core C166 CPU architecture for software compatibility across the product line.

Replacement Considerations

Direct substitutes may include other C164CI variants with different memory sizes or package types. Verify pinout compatibility and memory capacity matches before swapping. Consult official replacement guides for cross-referencing within the C166 family hierarchy.
