Product Summary

The PEF20534H10-V2.1 is a DMA Supported Serial Communication Controller with four independent serial channels1). The serial channels of the PEF20534H10-V2.1 are derived from updated protocol logic of the ESCC device family providing a large set of protocol support and variety in serial interface configuration. This allows easy integration to different environments and applications. A 33-MHz/32-bit PCI bus Master/Slave interface with integrated high performance DMA controllers provides data transfer from or to host memory with low bus utilization and easy software handshaking. An additional de-multiplexed bus interface mode of the PEF20534H10-V2.1 is provided for integration in non-PCI bus environments with little glue-logic depending on the bus type.
