MB86615PBT中文资料富士通数据手册PDF规格书

■ DESCRIPTION

The MB86615 is 1394 serial bus controller compatible with the IEEE 1394 “FireWire” standard (IEEE Standard 1394-1995). One built-in port plus a differential transceiver and comparator are provided to enable formation of networks in a 1394 cable environment. The MB86615 supports s100 data transfer speeds.

■ FEATURES

• Compatible with IEEE 1394 high-performance serial bus standards

• Physical layer and link layer integrated on one chip

• 1 cable ports

• Supports s100 transfer speed (98.304 Mbit/sec)

• 3.3V single power supply operation

• Built-in PLL (for crystal oscillator) for internal clock signal generation

• Power saving modes

1) Forced sleep mode at instruction from MPU

2) Automatic sleep mode for non-connected ports

• Header and data units automatically separated at receiving and automatic packetizing for sending

• Supports cycle master functions

• Built-in CSR’s to provide isochronous resource manager functions

• 32-bit CRC generation and check functions

• General purpose port for asynchronous transfer and control (16-bit MPU/DMA common bus)

• Exclusive built-in ports for isochronous transfer (8-bit bus)

• Built-in CRS’s and automatic processes to support DVC

1) Automatic separation of CIP headers at receiving, and automatic packetizing at sending.

2) Automatic generation and match detection of time stamp by FP signal.

3) DBC area automatic increment function

4) No-data packet sending and receiving

5) On-chip PCR (input/output 1 channel each)

6) Each CSR with automatic C&S lock processing and read processing

• Compatible with 4-core cable

• Packages: LQFP-100, FBGA-120
