C164CI8EMCBKXUMA1

Overview

The C164CI8EMCBKXUMA1 is a 16-bit microcontroller from the Infineon C166 family, operating at up to 25 MHz with a 4-stage pipeline. It features 64 KBytes of OTP program memory, 2 KBytes of IRAM, and 2 KBytes of XRAM within a 16 MByte linear address space. The device includes an on-chip CAN interface (Rev. 2.0B), an 8-channel 10-bit A/D converter, CAPCOM units, and multiple serial interfaces. It operates on a 5 V supply in a standard 80-pin MQFP package.

Feature Summary

• High-performance 16-bit CPU with hardware multiply/divide and single-cycle context switching
• Integrated full-function CAN interface supporting message objects for automotive communication
• On-chip programmable OTP memory allowing in-system reprogramming capabilities
• Flexible external bus controller supporting multiplexed or demultiplexed data/address buses

Applications

• Automotive body electronics and control systems
• Industrial embedded control applications
• Cost-sensitive motor control and automation solutions

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 RoHS directives and check for any end-of-life notices regarding production availability before finalizing procurement plans.

Selection Notes

Select this derivative when a robust 16-bit architecture with integrated CAN functionality is required. Consider the OTP memory type if field updates are necessary compared to mask ROM versions. Evaluate the 80-pin MQFP package constraints against PCB layout requirements and ensure the 5V supply voltage aligns with system power rails.
