Product details
Overview
TSB43AA82AIPGEEP from Texas Instruments is an 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 burst mode, and automated SBP-2 ORB/page table fetching for storage-class peripherals in digital video and high-speed peripheral interconnect applications.
For engineers reviewing the TSB43AA82AIPGEEP datasheet, TSB43AA82AIPGEEP pinout, TSB43AA82AIPGEEP application, or TSB43AA82AIPGEEP equivalent, key selection criteria include its 144-pin LQFP package, integrated 1.8-V internal regulator, three independent FIFOs (1512/4728/504 bytes), ATAPI Ultra-DMA and SCSI mode support, and DPP protocol capability for direct print systems.
Technical Context
The TSB43AA82AIPGEEP implements a full IEEE 1394a-2000 link-layer stack with hardware-accelerated SBP-2 transaction management, including automated ORB fetch, page table fetch, and status block transmit. It supports up to four initiators via firmware-managed timer-based arbitration.
Its host interface operates at up to 40 MHz with 8-/16-bit multiplexed or separated data/address bus modes, and integrates a voltage regulator to generate internal 1.8-V supply from a single 3.3-V rail-reducing external component count and system power consumption.
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 transfers for real-time AV streaming. |
| FIFO Memory | Asynchronous command FIFO: 1512 B; DMA FIFO: 4728 B; Config ROM/LOG FIFO: 504 B - enables concurrent command, data, and configuration handling without CPU intervention. |
| Host Interface | 8-/16-bit asynchronous/synchronous DMA with handshake and burst mode; compatible with MCU buses up to 40 MHz clock rate. |
| Power Supply | Single 3.3-V supply with internal 1.8-V regulator; eliminates need for external low-voltage rail in host system design. |
| Protocol Support | SBP-2 (Serial Bus Protocol 2) and DPP (Direct Print Protocol); enables plug-and-play mass storage and printer connectivity over 1394. |
Pinout & Package
LQFP-144 (PGE) package with 0.5-mm pitch, 20.20 mm × 20.20 mm body size, and JEDEC MS-026 compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Master clock input | Accepts 24.576-MHz crystal or oscillator reference for PHY/link timing; required for IEEE 1394 synchronization. |
| RESET# | Active-low reset input | Asynchronous hardware reset that clears internal state machines and FIFO pointers; must be held low ≥100 ns after power stabilization. |
| DMAREQ/DMACK# | DMA request/acknowledge | Handshake pair controlling DMA transfer initiation and completion; supports burst-mode transfers to reduce host bus overhead. |
| ASYNCH# | Interface mode select | Low = asynchronous bus mode; high = synchronous mode - configures timing relationship between address/data and control signals. |
| PHY_RX+/PHY_RX− PHY_TX+/PHY_TX− | Differential PHY I/O | Four-pin differential pair interface to external 1394 cable transceivers; requires controlled-impedance PCB routing (100 Ω differential). |
Key Features
| Feature | Design Value |
|---|---|
| Automated SBP-2 ORB Fetch | Hardware engine fetches Operation Request Blocks from host memory without CPU polling - reduces latency and frees MCU cycles for application tasks. |
| ConfigROM Read Response | On-chip logic automatically responds to remote node ConfigROM read requests per IEEE 1394 clause 8.4.2 - eliminates firmware implementation of ROM access handler. |
| Split Transaction Control | Integrated retry and timeout management (via CFR register) for split transactions - ensures robustness in congested or high-latency 1394 networks. |
| DPP Segment Data Unit (SDU) | ARF FIFO repurposed as SDU register for large print data payloads - enables direct print protocol compliance without external buffering. |
| ATAPI/SCSI Mode Support | Native command translation layer for Ultra-DMA and SCSI protocols - allows direct connection of hard drives and tape units without bridge ASICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IEEE 1394 link-layer controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB43AB22APGEP | Enhanced 800-Mbps PHY (1394b), same link-layer core; adds backward-compatible 1394a mode and improved jitter tolerance. | Required for new designs targeting FireWire 800 infrastructure or longer cable runs (>4.5 m). | Select when future-proofing for higher bandwidth or extended reach; not drop-in due to different PHY register map and layout constraints. |
| FWH1394-144 | Second-source 1394a PHY+link controller in identical LQFP-144 package; functionally aligned but with distinct FIFO sizing and interrupt architecture. | Suitable for cost-sensitive CE applications where TI supply continuity is constrained. | Verify firmware compatibility with ConfigROM initialization sequence and SBP-2 timer register offsets before integration. |
Compared with TSB43AA82AIPGEEP, the TSB43AB22APGEP offers double the PHY speed and better noise immunity but requires layout revision and firmware updates; the FWH1394-144 provides pin-compatible replacement potential but demands validation of SBP-2 transaction timing margins and interrupt latency behavior.
