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.
