MB86616

FUJITSU SEMICONDUCTOR DATA SHEET DS04-22005-1E ASSP Communication Control IEEE1394-SCSI Tailgate MB86616 s DESCRIPTION The MB86616 is the LSI for protocol conversion to connect SCSI devices to the IEEE 1394 bus. This LSI integrates a 1394 controller compliant with the IEEE Standard for High Performance Serial Bus (IEEE Std. 1394-1995, or FireWire standard) and an SCSI protocol controller compliant with the SCSI-Fast20 standard on a single chip. It also incorporates the F2MC-16F as a processor for controlling the individual on-chip controllers, providing ease of control. The IEEE 1394 controller unit has two ports for use in a cable environment and contains a differential transceiver and a comparator. It supports S400 data transfer rates. In addition, it supports the Chain command to continuously issue request packets for data transmission and reception, improving the efficiency of data transfer. The SCSI protocol controller unit conforms to 8-bit Fast20 SCSI, enabling data transfer at a maximum of 20 Mbyte/s. For the SCSI bus terminal, the unit contains a totem pole type of single-end driver/receiver so that it can drive the SCSI bus directly. While inheriting the AT architecture of the F2MC-16/16H family, the instruction set for the F2MC-16F CPU core incorporates additional instructions for high-level languages, supports extended addressing modes, and contains enhanced multiplication and division instructions as well as a substantial collection of improved bit manipulati...
