SAB82532H10V32A

Specialized Overview

The Infineon Technologies SAB82532H10V32A is an Enhanced Serial Communication Controller (ESCC2) fabricated using advanced CMOS technology. It features two independent full-duplex serial channels with on-chip clock generation and DPLL for clock recovery. The device supports a parallel 16-bit wide microprocessor interface compatible with Intel or Motorola architectures, utilizing 64-byte FIFOs per channel and direction. It operates in HDLC/SDLC, ASYNC, and BISYNC modes, supporting data rates up to 10 Mbit/s. The component is housed in a P-MQFP-80 package.

Specialized Feature Summary

• Supports multiprotocol communication including HDLC/SDLC, ASYNC, and character-oriented serial modes.
• Integrates two independent serial channels with programmable time-slot assignment and internal baud rate generators.
• Provides direct compatibility with 8/16-bit microprocessors via a flexible bus interface supporting DMA and interrupt daisy chaining.

Specialized Applications

• Universal multiprotocol communication boards for workstations and PCs
• Terminal controllers and computer peripherals
• Time-slotted packet networks and multimaster communication networks

Specialized Procurement Notes

Verify the specific ordering code Q67101-H6789 for the P-MQFP-80 variant when sourcing. Confirm that the V32 suffix aligns with the required version 3.2 user manual specifications. Ensure compatibility with the host system's voltage levels and bus timing requirements before integration.

Specialized Selection Notes

Select this controller for applications requiring high-speed serial communication with hardware protocol offloading. The H-10 variant is suitable for systems needing data rates up to 10 Mbit/s and time-slot mode capabilities. Ensure the design accommodates the P-MQFP-80 package outline and provides adequate thermal management for active power consumption.

Specialized Part Context

This component belongs to the ESCC2 family, which includes variants like the SAB 82525. It serves as a high-performance serial communication controller designed to reduce software overhead by handling layer-2 protocols independently of the host processor. The H-10 designation indicates support for higher data rates and telecom-specific time-slot operations compared to standard versions.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other ESCC2 variants if pinout and feature sets match the application requirements.
