C164CILMCAFNUMA2

Overview

The C164CILMCAFNUMA2 is a member of the Infineon C166 family, specifically the C164CI derivative series. It is a 16-bit single-chip CMOS microcontroller designed for cost-sensitive applications. The device features a high-performance CPU with a 4-stage pipeline and an instruction cycle time of 80 ns at a 25 MHz clock frequency. It includes on-chip memory modules such as internal RAM (IRAM), extension RAM (XRAM), and program mask ROM or OTP memory. The architecture supports a 16 MBytes total linear address space and provides enhanced peripheral functionality.

Feature Summary

• High-performance 16-bit CPU with a 4-stage pipeline architecture
• On-chip memory including IRAM, XRAM, and up to 64 KBytes of Mask ROM or OTP
• Integrated Peripheral Event Controller (PEC) for interrupt-driven data transfer
• Clock generation capabilities via on-chip PLL, prescaler, or direct input

Applications

• Cost-sensitive embedded control systems
• Industrial automation controllers
• Automotive electronic subsystems
• General-purpose microcontroller applications requiring 16-bit processing

Procurement Notes

Verify the specific suffix 'NUMA2' against official Infineon documentation to confirm exact package type, temperature range, and mass production status. Ensure compatibility with existing design constraints regarding the 25 MHz clock speed and 16-bit architecture before procurement.

Selection Notes

Select this component when a balance of high CPU performance and low cost is required. It is suitable for applications needing a 16-bit architecture with integrated peripherals like ADC and CAPCOM units. Consider the 80 ns instruction cycle time for timing-critical tasks within its specified operating voltage and temperature ranges.

Part Context

This part belongs to the C166 family of microcontrollers, which are known for combining high performance with rich peripheral sets. The C164CI derivatives are optimized for cost-sensitive markets while maintaining the robust feature set typical of the broader C166 architecture, including advanced interrupt handling and boolean bit manipulation.

Replacement Considerations

Direct replacements within the C166 family should be verified for pin-to-pin compatibility and identical memory configurations. Cross-referencing with other C164CI variants is recommended to ensure functional equivalence in terms of peripheral availability and electrical specifications.
