TSB12LV32IPZ

Controllers Overview

The TSB12LV32IPZ is a general-purpose IEEE 1394a-2000 link-layer controller designed for computer peripherals and consumer audio/video electronics. It supports transfer rates of 400, 200, or 100 Mbps and operates on a single 3.3-V supply with 5-V tolerance. The device features an 8-bit or 16-bit programmable microcontroller interface supporting multiple modes including burst mode, and a data-mover port for asynchronous streaming transmit/receive. It includes a 2-Kbyte general receive FIFO and a 2-Kbyte asynchronous transmit FIFO accessed through the microcontroller interface. The component is housed in a high-performance 100-pin LQFP package.

Controllers Feature Summary

• Supports IEEE 1394-1995 and P1394a standards for high-frequency performance up to 60 MHz
• Includes a two-channel support for isochronous receive and four-channel support for isochronous transmit
• Provides a glueless interface to 68000 and ColdFire microcontrollers/microprocessors
• Features backward compatibility with all Texas Instruments physical layer controllers

Controllers Applications

• Computer peripherals requiring IEEE 1394 connectivity
• Consumer audio and video electronics systems
• High-speed serial bus implementations utilizing GP2Lynx technology

Controllers Procurement Notes

Verify current production status as the TSB12LV32IPZ variant is listed as Not Recommended for New Designs (NRND). Confirm availability of alternative active versions such as the TSB12LV32PZ if new designs are required. Ensure compliance with RoHS and environmental specifications by checking the specific ordering suffix against the latest packaging information addendum provided by Texas Instruments.

Controllers Selection Notes

Select this component when designing systems that require a general-purpose link-layer controller compliant with IEEE 1394a-2000 standards. Consider the 100-pin LQFP package constraints and the need for a 3.3-V power supply with 5-V tolerance. Evaluate the requirement for a direct interface to host controllers via the programmable microcontroller interface or the data-mover port for large data block transfers.

Controllers Part Context

The TSB12LV32 series serves as a high-performance link-layer controller within the Texas Instruments GP2Lynx family. It facilitates data transfer between the 1394 Phy-link interface, external host controllers, and local bus interfaces. This part is distinct from enhanced product variants like the TSB12LV32-EP, which are designated for defense, aerospace, and medical applications.

Controllers Replacement Considerations

The TSB12LV32PZ is an active version of the same core device available in the same package. For military or aerospace requirements, the TSB12LV32-EP is the qualified enhanced product alternative.
