PSB 3186 F V1.4

Telecom Overview

The PSB 3186 F V1.4, designated as ISAC-SX TE, is an ISDN Subscriber Access Controller for Terminals developed by Infineon Technologies. This component integrates a D-channel HDLC controller and a four-wire S/T interface to connect voice and data terminals to the ISDN network. It builds upon the ISAC-S TE architecture with enhanced features. The device supports multiple parallel microcontroller interface configurations selectable via pin strapping, including multiplexed and demultiplexed modes. An optional indirect register access mechanism is available to simplify system integration.

Telecom Feature Summary

• Integrates a dedicated D-channel HDLC controller for efficient protocol handling.
• Provides a four-wire S/T interface compliant with ITU I.430 standards for terminal connectivity.
• Supports flexible host interfacing through configurable parallel microcontroller interfaces.
• Includes an optional indirect register access mechanism to streamline system design.

Telecom Applications

• ISDN subscriber access controllers for terminals
• Voice and data terminal interconnection to ISDN networks
• Layer-1 and Layer-2 protocol processing in ISDN systems

Telecom Procurement Notes

Verify the specific revision level against the datasheet dated January 30, 2003. Confirm that the ordering suffix corresponds to the required package and temperature range. Ensure compatibility with the intended host microcontroller interface configuration before procurement.

Telecom Selection Notes

Select this component for applications requiring ISDN S/T interface connectivity with integrated HDLC processing. Evaluate the host interface requirements to determine if multiplexed or demultiplexed parallel bus modes are suitable. Consider the indirect register access feature if pin count optimization is necessary for the target design.
