C164CI8E25MDBKXUMA1

Overview

The C164CI8E25MDBKXUMA1 is a 16-bit single-chip microcontroller from the Infineon C166 family, operating at up to 25 MHz. It features 64 KBytes of OTP program memory and 2 KBytes each of internal RAM (IRAM) and extension RAM (XRAM). The device includes an on-chip CAN interface (Rev. 2.0B active), an 8-channel 10-bit A/D converter, and multiple timer units. It utilizes a 4-stage pipeline CPU with hardware multiply/divide capabilities and supports up to 59 general-purpose I/O lines within an 80-pin MQFP package.

Feature Summary

• High-performance 16-bit CPU with 4-stage pipeline and hardware multiplication support
• Integrated full-function Controller Area Network (CAN) interface compliant with Rev. 2.0B
• On-chip programmable One-Time Programmable (OTP) memory for code storage
• Comprehensive peripheral set including ADC, CAPCOM units, and serial communication channels

Applications

• Automotive electronic control units requiring CAN bus connectivity
• Industrial automation systems utilizing high-speed interrupt processing
• Cost-sensitive embedded applications needing robust I/O capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required OTP configuration and package variant. Ensure compliance with automotive qualification standards if deployed in vehicle systems. Request official datasheets to validate pin assignments and electrical characteristics prior to integration.

Selection Notes

Select this derivative when a 16-bit architecture with integrated CAN functionality is required. Consider the 64 KByte OTP capacity for final production firmware deployment. Evaluate the 25 MHz clock speed against system timing requirements. Verify that the 80-pin MQFP package fits the available PCB footprint constraints.

Part Context

This component belongs to the C164CI/SI/C164CL/SL series within the broader C166 microcontroller family. It represents a cost-optimized solution compared to higher-end variants while maintaining core C166 instruction set compatibility.
