Description:

WD33C93A: A MOSNLSI 40/44 pin chip providing high and low level interface functions to the SCSI bus. Full SCSI bus features include arbitration, disconnect, reconnect, parity generation and checking, synchronous and asynchronous transfers up to 4 Mbytes/s, DMA, and built in 48ma drivers for direct connection to a single ended SCSI bus. The main differences between the WD33C93A and the previous version (WD33C93) are faster transfer rates, host parity generation and checking, an extended FIFO, faster command execution times and a number of new commands.
