C164CI8E25MDBFXQMA1

Overview

The C164CI8E25MDBFXQMA1 is a 16-bit single-chip microcontroller from the Infineon C166 family, housed in an 80-pin MQFP package. It features a high-performance CPU with a 4-stage pipeline and operates at frequencies up to 25 MHz. The device includes 64 KBytes of on-chip OTP memory, 2 KBytes of internal RAM (IRAM), and 2 KBytes of extension RAM (XRAM). Key peripherals include a full-function CAN interface (Rev. 2.0B active), an 8-channel 10-bit A/D converter, CAPCOM2 and CAPCOM6 units, and multiple serial channels.

Feature Summary

• High-performance 16-bit CPU with 4-stage pipeline supporting single-cycle context switching
• Integrated full-function CAN interface compliant with Rev. 2.0B active standard
• On-chip OTP memory for flexible code storage and in-system programming
• Comprehensive peripheral set including ADC, timers, and capture/compare units

Applications

• Automotive electronic control units requiring CAN communication
• Industrial automation systems utilizing real-time processing
• Cost-sensitive embedded applications needing robust I/O capabilities

Procurement Notes

Verify the specific ordering suffix against the official Infineon Product Catalog Microcontrollers to confirm package type and delivery format. Ensure compatibility with development tools such as C-compilers and emulators. Confirm that the OTP programming voltage requirements are met by the target system design.

Selection Notes

Select this derivative for applications requiring 64 KBytes of programmable memory and full CAN functionality. Consider the 25 MHz operating frequency for performance needs. Evaluate the 80-pin MQFP package constraints against board layout requirements. Verify that the 5 V supply voltage aligns with the system power architecture.

Part Context

This component belongs to the C164CI/SI/C164CL/SL derivative group within the broader C166 Family. It represents a cost-sensitive variant combining high CPU performance with extensive peripheral integration. The C164CI specifically denotes derivatives with full-function CAPCOM6 and CAN interfaces, distinguishing it from reduced-function variants like the C164CL.

Replacement Considerations

Consult the official Infineon Product Catalog Microcontrollers for verified substitute part numbers. Cross-reference pinouts and memory configurations when considering alternatives within the C166 family.
