SAF 82526 N V2.2

Specialized Overview

The SAF 82526 N V2.2 is a High-Level Serial Communication Controller Extended (HSCX) manufactured by Infineon Technologies, originally developed by Siemens. It operates on advanced ACMOS 3 technology within a P-LCC-44 pin package and requires a +5V power supply. The device implements one full-duplex HDLC channel (Channel B) with integrated Link Access Procedure controllers for LAPB, LAPD, and SDLC protocols. It features two independent baudrate generators, on-chip Digital Phase Locked Loops (DPLL) for clock recovery, and 64-byte FIFOs per direction to decouple serial interfaces from the system bus.

Specialized Feature Summary

• Supports Full-Duplex HDLC protocols including LAPB, LAPD, and SDLC with automatic frame handling
• Integrates on-chip DPLL for clock recovery and programmable time-slot assignment
• Provides efficient data transfer via 4-channel DMA interface or interrupt requests
• Features an 8-bit demultiplexed adaptive bus interface compatible with Intel and Motorola microcontrollers

Specialized Applications

• ISDN applications utilizing time division multiplex methods
• Packet switching systems requiring high-speed synchronous communication links
• Time-slot oriented PCM systems
• High-level serial communication controllers in embedded microprocessor environments

Specialized Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific revision matches project requirements as the part may be discontinued. Ensure proper handling procedures are followed due to surface mount packaging and static sensitivity classifications.

Specialized Selection Notes

Select this model when a single HDLC channel is sufficient for the application. The SAB 82525 variant should be considered if two independent channels are required. Verify compatibility with the target microcontroller's bus architecture, specifically regarding Intel or Motorola mode selection via strapping pins.

Specialized Part Context

This component belongs to the HSCX family, which includes the SAB 82525 and SAF 82525 variants. While the SAB 82525 provides two channels, the SAF 82526 is configured for a single channel (Channel B). The 'SAF' prefix typically denotes automotive-grade qualification compared to the standard 'SAB' series.
