C164CM4EFABKXUMA1

Overview

The C164CM4EFABKXUMA1 is a 16-bit single-chip microcontroller from the Infineon C166 family, featuring a 25 MHz CPU clock and an 80 ns instruction cycle time. It integrates 32 KBytes of on-chip OTP memory and 2 KBytes of internal RAM within a 16 MByte linear address space. The device includes a full-function CAN interface (Rev. 2.0B active), an 8-channel 10-bit A/D converter, and multiple capture/compare units. It operates at +5 V with extended temperature ranges and utilizes a 64-pin TQFP package.

Feature Summary

• High-performance 16-bit CPU with a 4-stage pipeline and hardware multiply/divide unit
• Integrated full-function Controller Area Network (CAN) interface supporting Rev. 2.0B
• On-chip 32 KByte OTP program memory and 2 KByte internal RAM
• Comprehensive peripheral set including 10-bit ADC, CAPCOM2, CAPCOM6, and serial channels

Applications

• Automotive electronic control units requiring CAN bus communication
• Industrial motor control systems utilizing PWM and capture features
• Cost-sensitive embedded applications needing high I/O density

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required OTP configuration and package variant. Ensure compliance with automotive qualification standards if deployed in safety-critical environments. Review the official datasheet for handling precautions regarding static sensitivity and voltage levels.

Selection Notes

Select this derivative when a 25 MHz operating frequency and 32 KByte OTP storage are required. The C164CM variant specifically supports the full-function CAN interface, unlike the C164SM. Consider the 64-pin TQFP footprint for board layout constraints. Evaluate the 10-bit ADC resolution against sensor requirements before finalizing the design.

Part Context

This component belongs to the C166 family of 16-bit microcontrollers designed by Infineon Technologies. It represents a cost-optimized solution combining RISC and CISC architectures. The C164CM designation indicates the inclusion of the CAN interface module, distinguishing it from other derivatives in the series.
