UPD7201

NEe Microcomputers, Inc. NEe fLPD7201 DEseR IPTION F EATU RES PIN CONFIGURATION MULTI-PROTOCOL SERIAL CONTROLLER The "PD7201 is a dual-channel multi-function peripheral controller designed to satisfy a wide variety of serial data communication requirements in microcomputer systems. Its basic function is a serial-to-parallel, parallel-to..erial converter/controller and within that role it is configurable by systems software so its ~'personality" can be optimized for a given serial data communications application_ The "PD7201 is capable of handling asynchronous and synchronous byte-oriented protocols such as IBM Bisync, and synchronous bit-oriented protocols such as HDLC and IBM SDLC_ This versatile device can also be used to support virtually any other serial protocol for applications other than data communications. The "PD7201 can generate and check CRC codes in any synchronous mode and can be programmed to check data integrity in various modes. The device also has facilities for mo...
