PEB20534H10-V21

Specialized Overview

The PEB20534H10-V21 is a DMA Supported Serial Communication Controller with 4 Channels (DSCC4) manufactured by Infineon Technologies. It functions as a multi-protocol controller designed for data communication and telecommunication applications. The device integrates four independent serial communication cores, a dedicated DMA controller, central FIFOs, and multiple peripheral interfaces including a PCI bus interface, a de-multiplexed bus interface extension, a local bus interface, a synchronous serial control interface, and a general-purpose port. It supports various protocols such as HDLC/SDLC, PPP, ASYNC, and BISYNC.

Specialized Feature Summary

• Integrates four serial communication cores supporting multiple standard protocols
• Includes an on-chip DMA controller with central transmit and receive FIFOs
• Provides flexible host connectivity via PCI and de-multiplexed bus interfaces
• Features a Multi Function Port with local bus, synchronous serial, and general-purpose capabilities

Specialized Applications

• High-Speed Serial Interface (HSSI) Data Circuit Terminating Equipment (DCE) adapters
• High-Speed Serial Interface (HSSI) Data Terminal Equipment (DTE) adapters
• General data communication applications requiring multi-channel serial processing

Specialized Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm component availability status as older revisions may be discontinued. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Specialized Selection Notes

Select this component when a high degree of protocol flexibility and direct memory access are required for serial communications. Evaluate the need for four independent channels versus simpler single-channel controllers. Consider the integration of the PCI interface and local bus options for system architecture simplification.

Specialized Part Context

This part belongs to the PEB 20534 family of serial communication controllers. It represents Version 2.1 of the DSCC4 architecture, which includes enhancements to the ESCC serial core and corrected timing values compared to previous revisions. The H10 variant specifically denotes the hardware configuration within this product line.

Specialized Replacement Considerations

Check for updated versions within the PEB 20534 series or compatible ESCC family members. Verify pinout and register compatibility if substituting with other serial communication controllers from Infineon or third-party manufacturers.
