MB86603

FUJITSU SEMICONDUCTOR DATA SHEET DS04–22410–1E ASSP COMMUNICATION CONTROL SCSI-2 PROTOCOL CONTROLLER MB86603 DESCRIPTION The MB86603 is a SCSI-2 protocol controller (SPC) that facilitates interface control between the host computer (medium/small) and peripheral devices. The specifications conform to the SCSI-2 standard but have an improved baud rate and extended functions. The MB86603 supports high-speed synchronous transfer, wide transfer (16 bits), the MPU/DMA stand-alone system bus, and programmable commands, to enable configuration of high-performance systems. The MB86603 (SPC hereafter) is applicable to both single-end and differential transmissions and has a driver/receiver that can drive single-end heavy current (48 mA). It can also have the phase-to-phase sequence control function to reduce the program overhead of the host MPU. For the abbreviations in this data sheet, see the next page. FEATURES SCSI Bus Interface Operable as initiator and target Two types of data transfer – Synchronous transfer: Max. 20 Mbytes/s, max. 32 offsets, 32-level baud rate – Asynchronous transfer: Max. 10 Mbytes/s Transfer parameters (transfer mode, baud rate, transfer offset for 15 connected devices) Single-end and differential transmissions Driver/receiver capable of driving 48-mA single-end heavy current Tristate bidirectional buffers for transfer control signals (REQ, ACK) w w .D w t a S a e h t e U 4 .c m o 176-Lead Plastic SQFP Package FPT-176P-M01 Copy...
