SAF82532N10V32A

Specialized Overview

The Infineon SAF82532N10V32A is an Enhanced Serial Communication Controller (ESCC2) fabricated using advanced CMOS technology. It features two independent full-duplex serial channels, each equipped with an on-chip clock generator and a Digital Phase-Locked Loop (DPLL) for clock recovery. The device supports data rates up to 10 Mbit/s in external clock mode and includes programmable time-slot assignment for telecom-specific applications. It provides a parallel 16-bit microprocessor interface compatible with Intel or Motorola architectures, alongside 64-byte FIFOs per channel and direction. Protocol support encompasses HDLC/SDLC, ASYNC, and BISYNC modes.

Specialized Feature Summary

• Dual independent serial channels with integrated DPLL for clock recovery
• Support for multiprotocol communication including HDLC, SDLC, ASYNC, and BISYNC
• Programmable time-slot assignment for time-division multiplexing applications
• Integrated CRC calculation and error handling for reliable data transmission

Specialized Applications

• Universal multiprotocol communication boards for workstations and PCs
• Terminal controllers and computer peripherals
• Time-slotted packet networks and multimaster communication networks
• Local Area Networks (LANs)

Specialized Procurement Notes

Verify the specific ordering code against official Siemens/Infineon documentation to ensure compatibility with the required package type, as the N-10 variant denotes specific high-speed capabilities. Confirm that the component meets all necessary environmental and safety standards for the intended deployment environment before integration into final systems.

Specialized Selection Notes

Select this controller when high-speed serial communication up to 10 Mbit/s is required with flexible protocol support. Ensure the host system can accommodate the 16-bit parallel interface and provide adequate power supply stability. Consider the available packages, such as P-LCC-68 or P-MQFP-80, based on board space and thermal management requirements.

Specialized Part Context

The ESCC2 series represents a significant advancement over earlier serial controllers like the SAB 82525, offering enhanced protocol handling and higher data throughput. It was designed to reduce hardware and software overhead in serial communications, making it suitable for complex networking environments requiring robust layer-2 protocol support.

Specialized Replacement Considerations

Direct replacements may include other variants within the ESCC2 family, such as the SAB 82532 H-10, depending on the required package and pinout compatibility. Verify functional equivalence regarding supported protocols and maximum data rates before substitution.
