C164CI8EMCBKXQMA1

Overview

The C164CI8EMCBKXQMA1 is a 16-bit single-chip microcontroller from the Infineon C166 family, housed in an 80-pin MQFP package. It features a 20 MHz CPU clock with up to 64 KBytes of OTP program memory and 2 KBytes each of internal RAM (IRAM) and extension RAM (XRAM). The device integrates a full-function CAN interface compliant with Rev 2.0B, supporting 15 message objects. Additional peripherals include an 8-channel 10-bit A/D converter, multiple capture/compare units (CAPCOM2 and CAPCOM6), serial communication channels (SSC, ASC), and general-purpose I/O lines.

Feature Summary

• High-performance 16-bit CPU with a 4-stage pipeline and dedicated hardware multiply/divide unit
• Integrated full-function Controller Area Network (CAN) interface with 15 message objects
• On-chip programmable One-Time Programmable (OTP) memory for code storage
• Comprehensive peripheral set including ADC, timers, and flexible external bus controller

Applications

• Automotive electronic control units requiring CAN communication
• Cost-sensitive industrial applications needing robust 16-bit processing
• Systems utilizing on-chip programmable memory for boot or configuration data
• Embedded controllers integrating analog sensing via the built-in ADC

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package and temperature range specifications. Ensure compliance with automotive quality standards if applicable to the end application. Review the official datasheet for any design-in warnings regarding life-support systems or voltage requirements.

Selection Notes

Select this derivative when a 16-bit architecture with integrated CAN functionality is required. The OTP memory option suits applications needing field-programmable code without mask ROM costs. Consider the 80-pin MQFP package constraints for PCB layout. Evaluate the 20 MHz operating frequency against system timing requirements and power consumption limits in idle or sleep modes.

Part Context

This component belongs to the C164CI/SI and C164CL/SL derivatives within the broader C166 Family. It is designed as a cost-effective solution combining high CPU performance with extensive peripheral integration. The C164CI variant specifically denotes devices with full-function CAPCOM6 and CAN interfaces, distinguishing it from reduced-function counterparts.
