Product details
Overview
PCI2050BPDV from Texas Instruments is a PCI-to-PCI bridge IC enabling high-performance interconnection between two 32-bit, 66-MHz PCI buses. It supports concurrent bidirectional burst transfers, write combining, and internal two-tier arbitration for up to nine secondary bus masters. It serves as a hierarchical bus expansion solution in industrial embedded systems requiring electrical loading isolation and CompactPCI hot-swap compliance.
For engineers reviewing the PCI2050BPDV datasheet, PCI2050BPDV pinout, PCI2050BPDV application, or PCI2050BPDV equivalent, key selection considerations include 66-MHz timing compliance, dual-bus latency (4-clock frame-to-frame delay), 3.3-V core with 5-V tolerant I/Os, and support for CompactPCI hot-swap and PCI power management (Revision 1.1).
Technical Context
The PCI2050BPDV implements a fully compliant PCI-to-PCI Bridge per Revision 1.1, featuring independent read/write buffers and pipeline architecture for concurrent primary–secondary bus transactions. It supports Type 0/Type 1 configuration cycles, PCI command decoding (e.g., Memory Read/Write, I/O Read/Write), and system error handling including posted write parity errors and master/target abort reporting.
Its arbitration logic includes primary bus arbitration and internal secondary bus arbitration for up to nine masters, with optional external arbiter support. Secondary clock generation provides ten configurable outputs, and JTAG boundary-scan (IEEE 1149.1) enables test access via TCK/TMS/TDI/TDO pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-PCI bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PLX Technology PCI9054-AB | PCI-to-PCI bridge with local bus interface (EISA/ISA-like); lacks native CompactPCI hot-swap support | Targeted at legacy local bus expansion rather than pure PCI hierarchy; requires additional glue logic for hot-swap | Choose when integrating non-PCI peripherals via local bus; avoid if CompactPCI compliance is required |
| Pericom PI7C9X20404A | PCI Express-to-PCI bridge (PCIe upstream, PCI downstream); supports PCIe 1.0a, not native PCI-to-PCI | Designed for PCIe migration paths; incompatible with pure PCI-only systems lacking PCIe root complex | Choose only in PCIe-native systems needing backward PCI compatibility; not a drop-in replacement |
Compared with PLX PCI9054-AB and Pericom PI7C9X20404A, the PCI2050BPDV delivers native dual-PCI interoperability with built-in hot-swap and power management-making it uniquely suited for modular, field-serviceable CompactPCI systems where strict PCI Local Bus compliance and deterministic latency are mandatory.

FAQ
What is the maximum supported PCI bus frequency for the PCI2050BPDV?
The PCI2050BPDV supports operation at up to 66 MHz on both its primary and secondary PCI buses, fully compliant with the PCI Local Bus Specification Revision 2.2. This allows high-throughput bridging in bandwidth-intensive applications such as imaging or real-time data acquisition, while maintaining strict setup/hold timing margins verified in TI's electrical characterization.
Does the PCI2050BPDV support hot-swap functionality, and what signals are required?
Yes, the PCI2050BPDV supports CompactPCI hot-swap per PICMG specification Revision 1.0. Required signals include HSENUM (hot-swap enable), HSLED (hot-swap status indicator), and HSSWITCH/GPIO3 (insertion detection). These are implemented on dedicated pins and integrated with internal state machines to coordinate power ramping, bus isolation, and configuration enumeration during live insertion.
How many secondary bus masters can the PCI2050BPDV arbitrate internally?
The PCI2050BPDV provides internal two-tier arbitration supporting up to nine secondary bus masters. This capability is implemented in hardware and does not require external logic. The bridge also supports connection to an external secondary bus arbiter for systems exceeding nine masters, preserving scalability in large backplane architectures.
What power management features does the PCI2050BPDV implement?
The PCI2050BPDV complies with the PCI Bus Power Management Interface Specification Revision 1.1, supporting D0 (fully on) through D3hot (soft off) states. It includes PMCSR register mapping, wake-on-PCI-event capability, and automatic transition coordination with host BIOS/ACPI firmware-enabling system-level power savings without compromising bridge initialization integrity.
Is the PCI2050BPDV pin-compatible with other variants in the PCI2050B family?
Yes, the PCI2050BPDV shares identical pinout and signal mapping with the PCI2050BPPM (also 208-pin QFP), allowing direct PCB footprint reuse. However, it is not pin-compatible with GHK/ZHK BGA variants (257-pin), which differ in mechanical layout, thermal pad configuration, and ball assignment-even though functional register sets and electrical behavior are identical across all PCI2050B packages.
