The TSB43AA82A is a high performance 1394 integrated PHY and link layer controller. It is compliant with the
IEEE 1394-1995 and IEEE 1394a-2000 specifications and supports asynchronous transfers.
TSB43AA82A 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 TSB43AA82A 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 TSB43AA82A 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 node’s 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.
