Fujitsu MB86603
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.DESCRIPTION
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 Copyright ©1994 by FUJITSU LIMITED w w w .D a S a t e e h U 4 t m o .c 1 MB86603 Tran...
