Product details
Overview
TSB43AA82PGE from Texas Instruments is a dual-function IEEE 1394a-2000–compliant integrated PHY and link-layer controller supporting 400-Mbps two-port physical layer operation, 8-/16-bit asynchronous/synchronous DMA interface with handshake and burst mode, and automated SBP-2 ORB/page table fetching for storage-class peripherals such as external hard drives and DVD burners.
For engineers reviewing the TSB43AA82PGE datasheet, TSB43AA82PGE pinout, TSB43AA82PGE application, or TSB43AA82PGE equivalent, key selection criteria include its 3.3-V single-supply operation with internal 1.8-V regulation, support for ATAPI Ultra-DMA and SCSI modes, and three independent FIFOs (1512-byte async command, 4728-byte DMA, 504-byte Config ROM/LOG) enabling high-throughput serial bus protocol 2 implementations.
Technical Context
The TSB43AA82PGE implements a fully integrated 1394a-2000 PHY plus link-layer controller in a single die, eliminating need for discrete PHY+link chipsets. It embeds automated header insert/strip logic for DMA transfers and supports split transaction control with programmable retry count and timeout via CFR register.
Its host interface operates at up to 40 MHz over multiplexed or separated 8-/16-bit data/address buses, and it delivers native SBP-2 compliance including automated management ORB fetching, linked ORB chaining, and status block transmission - all without firmware intervention for basic operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Compliance | IEEE 1394a-2000 and IEEE 1394-1995; enables interoperability with FireWire 400 devices and legacy 1394 networks. |
| Data Rate | 400 Mbps (two-port PHY); supports full-duplex isochronous and asynchronous traffic on separate ports. |
| Supply Voltage | Single 3.3-V supply with internal 1.8-V regulator; reduces system power delivery complexity and thermal load. |
| Host Interface | 8-/16-bit asynchronous/synchronous DMA with handshake and burst mode; compatible with microcontrollers operating up to 40 MHz. |
| FIFO Memory | Three independent FIFOs: 1512-byte async command, 4728-byte DMA, 504-byte Config ROM/LOG; prevents inter-channel contention and enables concurrent SBP-2 command/data flow. |
| Protocol Support | Native SBP-2 and DPP (Direct Print Protocol); handles up to four initiators with automated ORB fetch and page table management. |
Pinout & Package
LQFP-144 (PGE) package with 0.5-mm pitch, 20.0 mm × 20.0 mm body size, and JEDEC MS-026 compliant footprint; suitable for automated SMT assembly and thermal management in CE storage enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Reference clock input | Accepts 24.576-MHz crystal or oscillator signal to synchronize 1394 PHY timing and link-layer operations. |
| RESET# | Active-low reset input | Asynchronous hardware reset that clears internal state machines and FIFO pointers; requires ≥100 ns pulse width. |
| D[15:0] | Data bus (bidirectional) | 16-bit multiplexed or separated data path supporting ATAPI Ultra-DMA and SCSI command/data transfers. |
| A[15:0] | Address bus (multiplexed or separated) | Enables memory-mapped register access and Config ROM addressing; supports both microcontroller bus architectures. |

Key Features
| Feature | Design Value |
|---|---|
| Automated ConfigROM access | Hardware-accelerated read response to remote node queries; eliminates CPU polling and interrupt overhead during bus enumeration. |
| Split transaction control | Programmable single-retry protocol with configurable timeout; ensures robustness in noisy or congested 1394 network environments. |
| Three independent FIFOs | Isolates command, data, and configuration traffic paths; prevents starvation and enables deterministic latency for SBP-2 command queues. |
| ATAPI/SCSI mode support | Direct integration with storage controllers using standard Ultra-DMA or SCSI command sets; avoids translation firmware layer. |
| DPP capability | Uses asynchronous receive FIFO as SDU register for large segment data units; enables direct printer protocol implementation without external buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1394a PHY+link-layer controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB43AB22PGE | Supports 800-Mbps 1394b mode; adds 1394b backward compatibility and enhanced error detection. | Required for new designs targeting FireWire 800 infrastructure or mixed 1394a/1394b networks. | Select when future-proofing against 1394b adoption or needing higher bandwidth headroom. |
| FWH1394A | Single-chip 1394a PHY-only (no link layer); requires external microcontroller or ASIC for SBP-2 processing. | Suitable only where link-layer logic is implemented externally or firmware-controlled. | Choose only if existing design already implements SBP-2 in software or custom logic. |
Compared with TSB43AA82PGE, TSB43AB22PGE adds 1394b capability but increases cost and power; FWH1394A reduces integration but shifts SBP-2 complexity to system-level firmware - making TSB43AA82PGE optimal for turnkey FireWire 400 storage interfaces.

FAQ
What is the primary function of the TSB43AA82PGE in a FireWire system?
The TSB43AA82PGE serves as a fully integrated IEEE 1394a-2000 PHY and link-layer controller, handling physical signaling, packet assembly/disassembly, SBP-2 command processing, and DMA coordination. It enables direct connection of storage devices to FireWire hosts without requiring external link-layer logic - a core capability confirmed in TI's SLLA205 datasheet and supported by its three dedicated FIFOs and automated ORB fetch engine.
Does the TSB43AA82PGE support FireWire 800 (1394b) operation?
No, the TSB43AA82PGE is strictly IEEE 1394a-2000 compliant and supports only 100/200/400 Mbps signaling. It does not implement 1394b features such as beta-mode encoding, 800-Mbps operation, or cable-power negotiation. For 1394b support, TI recommends the TSB43AB22PGE - a documented functional successor with explicit 1394b capability outlined in its official datasheet.
What host bus configurations does the TSB43AA82PGE support?
The TSB43AA82PGE supports both 8-bit and 16-bit host interfaces in either multiplexed or separated data/address bus configurations, operating at up to 40 MHz. This flexibility allows direct interfacing with common microcontrollers and ASICs used in CE storage products, as verified in the "Host Bus Interface" section of the SLLA205 datasheet and confirmed by its D[15:0] and A[15:0] pin definitions.
Is the TSB43AA82PGE still in active production?
No - according to TI's official Packaging Information Addendum dated 11-Nov-2025, TSB43AA82PGE is marked "Obsolete" with no current production status. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including traceable sourcing and BOM continuity planning, to serve ongoing repair and replacement needs for deployed FireWire-based systems.
How does the TSB43AA82PGE handle SBP-2 command execution?
The TSB43AA82PGE implements hardware-accelerated SBP-2 command execution via its dedicated asynchronous command FIFO (1512 bytes) and automated ORB fetch engine. It supports up to four initiators, performs linked ORB chaining, and manages page table fetches for scatter-gather DMA - all without CPU intervention. This behavior is explicitly documented in TI's SLLA205 application report under "SBP-2 Related Functions" and verified in register-level descriptions of the CFR and ORB control logic.
