TSB12LV01BPZTG4

Controllers Overview

The TSB12LV01BPZTG4 is an IEEE 1394-1995 high-speed serial-bus link-layer controller manufactured by Texas Instruments. It operates from a 3.3-V power supply while maintaining 5-V tolerant inputs and supports transfer speeds of 100, 200, and 400 Mbits/s. The device features a generic 32-bit host bus interface and provides internal memory totaling 2K bytes, configurable as multiple variable-size FIFOs for asynchronous transmit, isochronous transmit, and general receive operations. It is available in a 100-pin PZT package.

Controllers Feature Summary

• Supports IEEE 1394-1995 standard with transfer speeds up to 400 Mbits/s
• Includes internal 2K-byte memory configured as multiple variable-size FIFOs
• Features a generic 32-bit host bus interface compatible with most 32-bit hosts
• Operates from a 3.3-V power supply with 5-V tolerant inputs

Controllers Applications

• IEEE 1394 high-performance serial bus I/O subsystem integration
• Data transfer between 32-bit host buses and external devices via local bus interface
• Cycle master functions requiring interrupt-driven operation to minimize host polling

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, temperature range, and lead finish specifications. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement to ensure compatibility with assembly processes.

Controllers Selection Notes

Select this component when designing systems requiring a compliant IEEE 1394-1995 link layer controller. Ensure the host interface clock duty cycle meets the specified requirements for frequencies at or above 50 MHz. Verify that the application does not require bus holder cells on the PHY-link interface, as these are omitted in this revision.

Controllers Part Context

This part is a revision of the TSB12LV01A, featuring feature enhancements and corrections while remaining pin-for-pin compatible. It adds two new internal registers and three programmable general-purpose output pins. Users should consult the transition document SLLA081 regarding specific pin changes and software compatibility extensions.

Controllers Replacement Considerations

The TSB12LV01A is the previous generation version. It is pin-for-pin compatible but lacks the feature enhancements found in the TSB12LV01B. Software compatibility requires verification of extensions noted in the datasheet.
