C164CM4EFABFXUMA1

Overview

The C164CM4EFABFXUMA1 is a 16-bit microcontroller from the Infineon C166 family, featuring a C166SV2 core and a 4-stage pipeline. It includes 32 KBytes of OTP program memory and 2 KBytes of internal RAM within a 16 MByte linear address space. The device integrates an on-chip CAN interface (Rev. 2.0B active) with 15 message objects, an 8-channel 10-bit ADC, and multiple capture/compare units. Operating frequencies reach up to 25 MHz via an on-chip PLL. It utilizes a 64-pin TQFP package and supports external bus expansion.

Feature Summary

• Integrates a full-function Controller Area Network (CAN) interface compliant with Rev. 2.0B active standards for robust communication.
• Features a high-performance 16-bit CPU with a 4-stage pipeline and hardware multiply/divide units for efficient processing.
• Includes an 8-channel 10-bit Analog-to-Digital Converter with programmable conversion times for signal acquisition.
• Provides flexible timer and PWM generation capabilities through CAPCOM2 and CAPCOM6 peripheral modules.

Applications

• Automotive engine control systems
• Industrial motor drive applications
• Cost-sensitive embedded control systems

Procurement Notes

Verify component authenticity against official Infineon documentation prior to integration. Confirm that the specific ordering suffix matches the required OTP memory configuration and package type. Ensure design compatibility with the 16-bit architecture and available development tools such as C-compilers and emulators. Review the datasheet for any errata or known limitations regarding the C164CM derivative.

Selection Notes

Select this component when a cost-effective 16-bit solution with integrated CAN functionality is required. The C164CM offers a balance of processing power and peripheral density suitable for applications not demanding high-end 32-bit performance. Consider the 32 KByte OTP limit for firmware size and verify that the 64-pin TQFP package fits the mechanical constraints. Evaluate if the 25 MHz maximum clock speed meets real-time processing requirements.

Part Context

This part belongs to the C164CM derivative series within the broader C166 Family of single-chip CMOS microcontrollers. It is designed for cost-sensitive applications requiring high CPU performance and extensive IO capabilities. The C164CM variant specifically distinguishes itself by including the on-chip CAN interface, unlike the C164SM counterpart which lacks this feature.
