TSB12LV01BIPZT

Controllers Overview

The TSB12LV01BIPZT is an IEEE 1394-1995 high-speed serial-bus link-layer controller manufactured by Texas Instruments. It facilitates data transfer between a 32-bit host bus, the 1394 PHY-link interface, and external devices. The device supports transfer speeds of 100, 200, and 400 Mbits/s and operates from a 3.3-V power supply while maintaining 5-V tolerant inputs. It features asynchronous and isochronous data transfers, interrupt-driven operation to minimize host polling, and generates/checks 32-bit CRC. An internal 2K-byte memory provides configurable FIFOs for general receive, asynchronous transmit, and isochronous transmit operations. It is housed in a 100-pin PZT package.

Controllers Feature Summary

• Supports IEEE 1394-1995 standard with transfer speeds up to 400 Mbits/s
• Provides a generic 32-bit host bus interface for direct register access
• Includes internal 2K-byte memory configured as variable-size FIFOs
• Operates on a 3.3-V supply with 5-V tolerant inputs

Controllers Applications

• I/O subsystem integration
• High-performance serial bus interfaces
• Data transfer between host buses and physical layer devices

Controllers Procurement Notes

Verify the component status is ACTIVE before ordering. Confirm the package type is TQFP (PZT) with 100 pins. Ensure the operating temperature range matches your design requirements, specifically noting the distinction between commercial and industrial grades if applicable. Check for RoHS compliance and moisture sensitivity level details in the latest datasheet revision.

Controllers Selection Notes

Select this part when integrating an IEEE 1394-1995 compliant link layer into a system requiring a 32-bit host interface. It is suitable for applications needing support for 100, 200, and 400 Mbits/s speeds. Consider the internal 2K-byte FIFO capacity for buffering needs. Ensure the host clock duty cycle constraints are met if operating at 50 MHz.

Controllers Part Context

The TSB12LV01BIPZT is a revision of the TSB12LV01A, featuring pin-for-pin compatibility with specific restrictions. Enhancements include new internal registers at CFR addresses 40h and 44h, three programmable general-purpose output pins, and corrections to previous errata. It eliminates the need for external FIFOs through its integrated memory structure.
