1 Pc. Z 80 ASIO (Z8444AC1) PLCC 44 Serial Input/output controller Sgs Thomson

The Z80 SIO 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 dat communications (cassette or floppy disk interface for example).
