SAF 82525 N V2.2

Specialized Overview

The Infineon Technologies SAF 82525 N V2.2 is a High-Level Serial Communication Controller Extended (HSCX) fabricated using advanced ACMOS technology. It provides two independent full-duplex HDLC channels within a P-LCC-44 surface-mount package. The device operates on a +5V supply and supports data rates up to 4 Mbit/s. It features an 8-bit demultiplexed adaptive bus interface compatible with Intel or Motorola microcontrollers, alongside a 4-channel DMA interface for efficient memory transfer. Each channel includes 64-byte transmit and receive FIFOs.

Specialized Feature Summary

• Supports LAPB, LAPD, SDLC, and HDLC protocols in auto-mode
• Includes internal DPLL for clock recovery per channel
• Provides programmable time-slot assignment for TDM systems
• Features transparent transmission and reception modes

Specialized Applications

• ISDN applications utilizing time division multiplex methods
• Packet switching systems requiring high-speed serial links
• Time-slot oriented PCM system implementations

Specialized Procurement Notes

Verify component authenticity through authorized distributors as the part is discontinued. Confirm package integrity and pin alignment against the P-LCC-44 specification before integration into legacy designs.

Specialized Selection Notes

Select this controller for systems requiring dual-channel synchronous serial communication with hardware protocol offloading. Ensure the host processor supports the required 8-bit bus interface and DMA architecture for optimal performance.
