Description : ICs for Communications Enhanced Serial Communication Controller

Introduction
The Enhanced Serial Communication Controller ESCC2 (SAB 82532/SAF 82532) is a multiprotocol Data communication controller with two symmetrical serial channels. It has been designed to implement high-speed communication links and to reduce hardware and software overhead needed for serial synchronous/asynchronous Communications.
Each channel contains an independent clock generator, DPLL, encoder/decoder and programmable protocol hardware. Data communication with asynchronous, synchronous character oriented, and HDLC based protocols with extended support of X.25 LAPB, the ISDN LAPD, and SDLC protocols is implemented. Like the SAB 82525 (HSCX) which is a functional subset of the ESCC2, the ESCC2 is capable of handling a large set of layer-2 protocol functions independently of the host processor.
