The TSB43AA82 is a high performance 1394 integrated PHY and link layer controller. It is compliant with the IEEE 1394-1995 and IEEE1394.a-2000 specifications and supports asynchronous transfers.
TSB43AA82 has a generic 16/8-bit host bus interface. It supports parallel or multiplexed connections to the microcontroller (MCU) at rates up to 40 MHz.
The TSB43AA82 offers large data transfers with three mutually independent FIFOs: 1) the asynchronous command FIFO with 1512 Bytes, 2) the DMA FIFO with 4728 bytes and 3) the Config ROM/LOG FIFO with 504 bytes.
The features of the TSB43AA82 support the serial bus protocol 2 (SBP-2). It handles up to four initiators with the SBP-2 transaction/timer manager. This SBP-2 transaction engine supports fully automated operation request block (ORB) fetches and fully automated memory page table fetches for both read and write transactions. Automated responses to other node requests are provided, this includes responding to another nodes read request to the Config ROM and issuing ack_busy_X for a single retry. Various control registers enable the user to program IEEE 1394 asynchronous transaction settings. The user can program the number of retries and the split transaction time-out value by setting the time limit register in the CFR.
The TSB43AA82 also supports the direct print protocol (DPP). The asynchronous receive FIFO (ARF) in the TSB43AA82 is large enough to satisfy the connection register area, the DRF receiving FIFO can be used as the segment data unit (SDU) register to fulfill the large data transfer.
