DESCRIPTION
(PHYs) Supports Provision of IEEE 1394-1995 (1394) Standard for High-Performance Supports Transfer Speeds of 100, 200, and Serial Bus 400 Mbits/s Transmits and Receives Correctly Timing Compliant with IEEE 1394a 2000 Formatted 1394 Packets Host Bus Interface Supports Asynchronous and Isochronous Provides Chip Control With Directly Data Transfers Addressable Registers Performs Function of 1394 Cycle Master Is Interrupt Driven to Minimize Host Polling Generates and Checks 32-Bit CRC Has a Generic 32-Bit Host Bus Interface Detects Lost Cycle-Start Messages General Contains Asynchronous, Isochronous, and Operates From a 3.3-V Power Supply While General-Receive FIFOs Totaling Bytes Maintaining 5-V Tolerant Inputs Manufactured With Low-Power CMOS Technology 100-Pin PZT Package for C to C and -40 C to C Temperature) Operation The TSB12LV01B is an IEEE 1394-1995 standard (from now on referred to only as 1394) high-speed serial-bus link-layer controller that allows for easy integration into an I/O subsystem. The TSB12LV01B provides a high-performance IEEE 1394-1995 interface with the capability of transferring data between the 32-bit host bus, the 1394 PHY-link interface, and external devices connected to the local bus interface. The 1394 PHY-link interface provides the connection to the 1394 physical (PHY) layer device and is supported by the link-layer controller (LLC). The LLC provides the control for transmitting and receiving 1394 packet data between the FIFO and PHY-link interface at rates of 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s. The TSB12LV01B transmits and receives correctly-formatted 1394 packets and generates and inspects the 32-bit cyclic redundancy check (CRC). The TSB12LV01B is capable of being cycle master and supports reception of isochronous data on two channels. TSB12LV01B has a generic 32-bit host bus interface, which will connect to most 32-bit hosts. The LLC also provides the capability to receive status from the physical layer device and to access the physical layer control and status registers by the application software. An internal 2K-byte memory is provided that can be configured as multiple variable-size FIFOs and eliminates the need for external FIFOs. Separate FIFOs can be user configured to support general 1394 receive, asynchronous transmit, and isochronous transmit transfer operations. These functions are accomplished by appropriately sizing the general receive FIFO (GRF), asynchronous transmit FIFO (ATF), and isochronous transmit FIFO (ITF). The TSB12LV01B is a revision of the TSB12LV01A, with feature enhancements and corrections. It is pin for pin compatible with the TSB12LV01A with the restrictions noted below. It is also software compatible with the extensions noted below. All errata items to the TSB12LV01A have been fixed, and the following feature enhancements have been made: Two new internal registers have been added at CFR address 40h and 44h. The Host Bus Control Register at 40h and the Mux Control Register @44h Three programmable general-purpose output pins have been added. Several pin changes have been made.

www.ti.com TSB12LV01B SLLA212 JUNE 2006 However, there are three restrictions that were not present in the TSB12LV01A device: The TSB12LV01B may only operate with a MHz host-interface clock (BCLK) if the duty cycle is less than away from the 50-50 point, (i.e., the duty cycle must be within 45-55% inclusive). A 40-60% duty cycle clock is acceptable for host clock frequencies at or below MHz. The TSB12LV01B does not have bus holder cells on the PHY-link interface. As a result of removing the bus holder cells, the ISO pin (pin 69) was replaced with a Vcc pin on the TSB12LV01B. This document is not intended to serve as a tutorial on 1394; users are referred to the IEEE 1394-1995 serial bus standard for detailed information regarding the 1394 high-speed serial bus.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2)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/productcontentfor 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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
