Product details
Overview
PCI4512ZHK from Texas Instruments is a single-socket CardBus controller IC integrating IEEE 1394a-2000 OHCI two-port PHY/link-layer functionality, supporting 32-bit/33-MHz PCI bus interface and 16-bit CardBus socket control. It delivers full OHCI-compliant FireWire connectivity with integrated power management, serial EEPROM I²C interface, and multifunction terminal routing for PC Card systems.
For engineers reviewing the PCI4512ZHK datasheet, PCI4512ZHK pinout, PCI4512ZHK application, or PCI4512ZHK equivalent, this device serves as a legacy embedded controller for portable computing peripherals requiring simultaneous CardBus host bridge and dual-port FireWire support in space-constrained designs.
Technical Context
The PCI4512ZHK implements a PCI-to-CardBus bridge with Function 0 (CardBus subsystem), Function 1 (OHCI 1394 controller), and optional Functions 2–4 (Flash Media, SD Host, Smart Card). It supports PCI Bus Mastering for 1394 DMA transfers and uses an internal 48-MHz clock source for timing-critical OHCI operations.
Its power architecture includes integrated low-dropout voltage regulation (LDO-VR), Clock Run Protocol compliance, and ACPI 1.0–compatible suspend/resume states across all functions. The device handles PC Card insertion/removal detection, low-voltage card sensing, and ring-indicate signaling via dedicated multifunctional terminals.

Applications
| Portable Notebook Expansion | Industrial Data Acquisition Module |
|---|---|
Use Scenario: Adding FireWire and CardBus peripheral support to legacy notebooks lacking native 1394 ports.

Use Value: Achieves sub-100-µs interrupt response for trigger events and sustained 20 MB/s write throughput to CF cards-critical for oscilloscope-class capture. |
| Medical Imaging Peripheral | Legacy Test Equipment Upgrade |
Use Scenario: Retrofitting ultrasound machines with FireWire video output and removable diagnostic storage media. IC Role / Device Role / Timing Role: PCI4512ZHK manages concurrent OHCI isochronous transfers (video) and CardBus PIO/DMA (DICOM storage), with separate power domains per function.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CardBus + IEEE 1394 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2046B | USB 2.0 hub controller only; no CardBus or 1394 support; 32-pin QFN package | Targets USB peripheral expansion-not FireWire or PC Card systems | Select only if replacing legacy FireWire with USB-based instrumentation interfaces |
| PCI6412ZHK | Same family, higher-performance variant: supports 64-bit PCI bus and enhanced OHCI features (e.g., improved DMA chaining) | Requires 64-bit PCI slot and updated BIOS support; not drop-in compatible with 32-bit-only hosts | Choose when upgrading host platform to 64-bit PCI and needing higher bandwidth for multi-camera 1394b systems |
Compared with PCI4512ZHK, TUSB2046B lacks CardBus and FireWire functionality entirely, while PCI6412ZHK extends capability at the cost of 32-bit PCI compatibility-making PCI4512ZHK the optimal fit for cost-sensitive, space-constrained 32-bit embedded CardBus designs requiring dual-port FireWire.

FAQ
What is the primary function of the PCI4512ZHK in a PC Card system?
The PCI4512ZHK serves as a multifunction PCI-to-CardBus bridge with integrated IEEE 1394a OHCI controller. In a PC Card system, it enables host CPU communication with CardBus peripherals while simultaneously providing dual-port FireWire connectivity-handling socket arbitration, power switching, card detection, and OHCI link-layer protocol processing. Its design consolidates what would otherwise require three discrete ICs.
Does the PCI4512ZHK require an external crystal for IEEE 1394 operation?
No, the PCI4512ZHK does not require an external crystal for IEEE 1394 operation. It incorporates an internal 48-MHz ring oscillator that meets OHCI 1.1 timing jitter specifications for S100–S400 data rates. This eliminates crystal placement, load capacitor tuning, and associated EMI concerns-confirmed in Section 3.5.6 of SCPS110.
Can the PCI4512ZHK support both 3.3-V and 5-V PC Cards?
Yes, the PCI4512ZHK supports both 3.3-V and 5-V PC Cards through dedicated voltage sense inputs (VS1#, VS2#) and integrated power switch interface logic. It automatically detects card voltage class and configures level-shifting circuitry accordingly-detailed in Sections 2.1.11 and 3.5.2 of the SCPS110 data manual.
How many PCI functions does the PCI4512ZHK expose, and what are they?
The PCI4512ZHK exposes five PCI functions: Function 0 (CardBus subsystem), Function 1 (OHCI 1394 controller), Function 2 (Flash Media interface), Function 3 (SD Host controller), and Function 4 (Smart Card interface). Each function has independent configuration space, interrupt assignment, and power state control-documented in Sections 3.4.4–3.4.8 of SCPS110.
Is the PCI4512ZHK pin-compatible with other devices in the PCIxx12 family?
No, the PCI4512ZHK is not pin-compatible with other PCIxx12 variants such as PCI6412ZHK or PCI6612ZHK. While sharing the same 208-pin LQFP package footprint, pin assignments differ significantly-particularly for PCI bus width signals (e.g., AD[63:32] on 64-bit variants) and OHCI enhancement features. Refer to Section 2.8 of SCPS110 for exact terminal mapping per part number.
