WD1933 Datasheet PDF

Western Digital WD1933

The WD1933 is a MOS/LSI microcomputer peripheral device which performs the functioning of interfacing a parallel digilal system to a synchronous serial data communication channel employing ISO's HDLC, IBM's SDLC or ANSI's ADCCP line protocol, These protocols are referred to as BitOriented Protocols (BOP). The chip is fabricated in N-channel depletion load MOS technology and is TIL compatible on all inputs and outputs. This controller requires a minimum of CPU software by supporting a comprehensive frame-level instruction set and by hardware implementation of the low level tasks associated with frame assembly/disassembly and data integrity.
