DESCRIPTION
The TSB12LV32 (GP2Lynx) is a high-performance general-purpose IEEE 1394a-2000 link-layer controller (LLC)
with the capability of transferring data between the 1394 Phy-link interface, an external host controller, and an
external device connected to the data-mover port (local bus interface). The 1394 Phy-link interface provides the
connection to a 1394 physical layer device and is supported by the LLC. The LLC provides the control for
transmitting and receiving 1394 packet data between the microcontroller interface and the Phy-link interface via
internal 2-Kbyte FIFOs at rates up to 400 Mbps. The TSB12LV32 transmits and receives correctly formatted
1394 packets, generates and detects the 1394 cycle start packets, communicates transaction layer transmit
requests to the Phy, and generates and inspects the 32-bit cyclic redundancy check (CRC).
The TSB12LV32 is capable of being 1394 cycle master (CM), 1394 bus manager, 1394 isochronous resource
manager (IRM) if additional control status registers (CSRs) are added via the external host controller, and
supports reception of 1394 isochronous data on two channels and transmission of 1394 isochronous data on
four channels.
The TSB12LV32 supports a direct interface to many microprocessors/microcontrollers by including
programmable endian swapping. TSB12LV32 has a generic 16-/8-bit host bus interface which includes support
for a ColdFireE microcontroller mode at rates up to 60 MHz. The microcontroller interface can operate in byte or
word (16 bit) accesses.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

SLLA215 – JUNE 2006
The data-mover block in GP2Lynx handles the external memory interface of large data blocks. This local bus
interface can be configured either to transmit or receive data packets. The packets can be either asynchronous,
isochronous, or asynchronous streaming data packets. The data-mover (DM) port can receive any type of
packet, but it can only transmit one type of packet at a time: isochronous data packets, asynchronous data
packets, or asynchronous stream data packets.
The internal FIFO is separated into an asynchronous transmit FIFO (ATF) and a general receive FIFO (GRF),
each of 520 quadlets (2 Kbytes). Asynchronous and/or isochronous receive packets can be routed to either the
DM port or the GRF via the receiver routing control logic. Asynchronous data packets or asynchronous stream
data packets can be transmitted from the DM port or the internal FIFO: ATF. If there is contention the ATF has
priority and is transmitted first. Isochronous packets can only be transmitted by the data-mover port.
The LLC also provides the capability to receive status information from the physical layer device and to access
the physical layer control and status registers by the application software.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
