This document is the Texas Instruments TSB12C01A Data Manual, which introduces the IEEE 1394-1995 High-Speed Serial-Bus Link-Layer Controller SLLS219B
The TSB12C01A is an IEEE‑1394‑1995 high‑speed serial‑bus link‑layer controller that integrates into 1394 subsystems, handling packet transmission, CRC generation, and cycle‑master functions. It supports bus speeds of 100, 200, and 400 Mb/s and offers configurable asynchronous, isochronous, and general‑receive FIFOs.
This manual details the device’s features, architecture, internal registers, data formats, electrical characteristics, and mechanical dimensions, including package options and power requirements.
