Product details
Overview
PCI1420GHK from Texas Instruments is a PCI-to-PC Card controller supporting single-slot 16-bit PC Card and CardBus sockets with 3.3-V core logic, universal PCI interface (3.3-V/5-V compatible), five PCI memory windows, two I/O windows, and pipelined architecture enabling >130-Mbps sustained throughput. It implements ExCA-compliant register mapping in memory and I/O space for notebook/desktop host systems.
For engineers reviewing the PCI1420GHK datasheet, PCI1420GHK pinout, PCI1420GHK application, or PCI1420GHK equivalent, key selection criteria include hot-insertion support, D3hot/D3cold wake capability, register compatibility with Intel 82365SL-DF, programmable CLKRUN output, and MicroStar BGA™ package with 144 terminals.
Technical Context
The PCI1420GHK operates as both PCI master and slave, initiating bus mastering during 16-bit PC Card DMA or CardBus bridging transactions. Its internal data path supports 8-, 16-, and 32-bit card access using full 32-bit PCI cycles, with independent buffering and pipeline staging to sustain burst transfers.
It complies with PCI Local Bus Specification Rev 2.2 and PCI Bus Power Management Interface Specification for PCI-to-CardBus Bridges. All card signals are internally buffered to enable hot insertion/removal without external components, and it supports multiple interrupt signaling modes: parallel PCI, parallel ISA, serialized ISA, and serialized PCI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-PC Card bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI1410GGU | Same die, identical electrical specs and register map; differs only in BGA package ball layout (GGU vs GHK) and thermal pad configuration | Requires PCB redesign due to different ball pitch (0.8 mm vs 1.0 mm) and land pattern; not mechanically interchangeable | Select PCI1410GGU only if sourcing legacy GGU-layout boards or when TI's GHK supply is constrained |
| PLX Technology PCI9050 | PCI-to-local bus bridge (not PC Card-specific); lacks ExCA registers, CardBus support, and integrated card power switching logic | Suitable only with custom PC Card interface ASIC or FPGA; requires full driver development versus plug-and-play ExCA stack | Choose PCI9050 only for highly customized designs where flexibility outweighs certification time and driver maturity |
Compared with PCI1410GGU, PCI1420GHK offers identical functionality but in a thermally enhanced GHK package optimized for higher ambient operating temperatures; versus PCI9050, it delivers turnkey PC Card support with zero FPGA logic or driver porting effort.

FAQ
Is PCI1420GHK pin-compatible with Intel 82365SL-DF controllers?
Yes, PCI1420GHK is register-compatible with Intel 82365SL-DF and 82365SL ExCA controllers, meaning its memory-mapped and I/O-mapped register set matches exactly-including offsets, bit definitions, and access semantics. However, physical pinout differs entirely as PCI1420GHK uses a 144-ball BGA while Intel's part uses a QFP package; PCB redesign is required for replacement.
What power supply requirements does PCI1420GHK have?
PCI1420GHK requires a single 3.3-V core supply for logic operation, with separate 3.3-V or 5-V I/O supplies for PC Card socket interfacing. The device supports universal PCI signaling, allowing connection to both 3.3-V and 5-V PCI buses without level shifters. Decoupling capacitors must meet TI's recommended values per SLLA226 layout guidelines.
Does PCI1420GHK support CardBus 32-bit mode?
Yes, PCI1420GHK fully supports CardBus 32-bit mode at 33 MHz, providing two dedicated I/O windows and two memory windows for the CardBus socket. Its internal 32-bit data path and pipelined architecture enable sustained throughput exceeding 130 Mbps in both directions-meeting the performance requirements defined in the 1997 PC Card Standard for CardBus operation.
Can PCI1420GHK be used in new designs despite TI's "Not Recommended" status?
While TI classifies PCI1420GHK as "Not Recommended for New Designs", it remains actively supported for lifecycle continuity in existing platforms. Aetrix Electronics maintains strategic inventory and provides full technical documentation, making PCI1420GHK viable for sustaining engineering, repair, and legacy system refresh programs where PC Card compatibility is mandatory.
How does PCI1420GHK handle hot insertion and removal of PC Cards?
PCI1420GHK internally buffers all PC Card signals-including VCC, VPP, and I/O lines-eliminating the need for external hot-swap controllers or discrete FETs. Its ExCA-compliant state machine manages power sequencing, signal isolation, and interrupt assertion during insertion/removal events, ensuring safe operation per PC Card Standard requirements without additional board-level circuitry.
