FUJITSU SEMICONDUCTOR DATA SHEET DS04-22415-1E ASSP CMOS munication Control SCSI-II Protocol Controller (with single-ended driver/receiver) MB86604L s DESCRIPTION The Fujitsu MB86604L is a single-ended transmission type SCSI-II Protocol Controller (SPC) with a single-ended driver/receiver. The MB86604L facilitates interface control between small/medium host puter and peripheral devices (such as a hard disk and printer). The specifications conform to the SCSI-II Standard. The MB86604L supports high-speed synchronous transfer, the MPU/DMA independent system data bus, and user programmable mand set to enable configuration of high-performance systems. It can also have the phase-to-phase sequence control function to reduce the program overhead of the host MPU. The MB86604L incorporate with a single-ended type SCSI driver/receiver which can drive 48 m A of large-current, and so, the device can be directly connected with the SCSI bus. The device can operate with +5 V single-power supply and in up to 40 MHz clock frequency. As for package, a 100-pin plastic small quad flat package is available. s Features SCSI Bus Interface: - Conforming to the SCSI-II standard - Operatable as Initiator and target (Continued) s PACKAGE 100 pin, Plastic LQFP (FPT-100P-M05) (Continued) - Two types of high-speed data transfer: - Synchronous data transfer (Max. 10 Mbytes/s, max. 32 offsets, 32-step transfer rate) - Asynchronous data transfer (Max. 5 Mbyte/s) - Transfer parameters (transfer mode, transfer rate, transfer offset) can be set for up to 7 connected devices. - Single-ended transmission type (Maximum cable length: 6 m): - On-chip single-ended driver/receiver which can drive 48 m A of "L" level output current - Directly connectable with the SCSI bus - On-chip three-state bidirectional I/O buffers for SCSI REQ and ACK pins (DB7-DB0, DBP , ATN, MSG, C/D, I/ O pins can be selected from either three-state or open-drain buffer by controlling the TEST pins input.)...
