C165LF3VHAFXUMA1

Overview

The C165LF3VHAFXUMA1 is a 16-bit microcontroller from the SAxC165 series, utilizing the C166 core architecture. It operates at a maximum clock frequency of 20 MHz with a single 3.3 V power supply. The device features 2 kB of data RAM and lacks internal program memory (ROM less). It provides 77 general-purpose I/O lines and includes five timer/counters. Packaged in an MQFP-100 format, it supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates the C166 16-bit core for efficient processing within automotive and industrial environments.
• Designed for low-voltage operation using a fixed 3.3 V power supply specification.
• Includes multiple hardware timers and counters for precise timing control applications.

Applications

• Automotive electronic control units
• Industrial motor control systems
• General embedded logic applications

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm that the specific suffix matches the required voltage and package specifications. Check current lifecycle status as availability may be limited due to discontinuation. Ensure proper handling procedures are followed given moisture sensitivity classification requirements during storage and assembly.

Selection Notes

Select this component when a 16-bit C166 architecture is required with strict 3.3 V operation constraints. Consider the absence of onboard ROM necessitating external memory interfaces if code storage is needed. Evaluate the MQFP-100 footprint against available PCB space. Verify that the 20 MHz speed meets real-time processing demands for the target application.
