Product details
Overview
PCI1620ZHK from Texas Instruments is a dual-socket PC Card and UltraMedia™ controller implementing three PCI functions: two independent PC Card socket controllers (Functions 0 & 1) and a firmware loader interface (Function 2). It supports 16-bit PC Cards, CardBus, SmartMedia™, MultiMediaCard, SD Card, Memory Stick™, and Smart Card adapters with 1.8-V core logic, 3.3-V I/O, and integrated voltage regulation. It enables hot insertion/removal in notebook and embedded host systems.
For engineers reviewing the PCI1620ZHK datasheet, PCI1620ZHK pinout, PCI1620ZHK application, or PCI1620ZHK equivalent, key selection considerations include PCI Local Bus Specification 2.2 compliance, PC Card Standard 8.0 support, ExCA register compatibility with Intel 82365SL–DF, dual-socket power management, and UltraMedia™ firmware loading capability via Function 2.
Technical Context
The PCI1620ZHK implements a multifunction PCI device with separate configuration spaces per socket and supports serialized IRQ, PCI LOCK, CLKRUN, and ACPI-compliant general-purpose events. Its internal data path enables full 32-bit PCI cycles for 8-/16-/32-bit card access, with independent buffering and pipelined bursting up to 132 MBps.
It integrates a serial EEPROM interface for subsystem ID/vendor ID loading, supports external zoomed video, and provides dedicated terminals for ring indicate, suspend, and PCI clock run. Power management includes PCI Bus Power Management Interface Specification 1.1 compliance and multiple low-power modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card and UltraMedia controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI1620GHK | Identical silicon die and functionality; differs only in BGA package marking (GHK vs ZHK); same 209-ball CROSTAR footprint and pinout | No functional difference; used interchangeably in TI reference designs and layout footprints | Select GHK if sourcing legacy inventory; ZHK and GHK share identical electrical, thermal, and mechanical specifications |
| PCI1620PDV | LQFP-208 package variant; lacks BGA-specific thermal performance and board-area efficiency; same register set and firmware loader capability | Suitable for prototyping or low-volume designs where BGA rework is impractical; lower I/O density limits high-speed signal routing | Choose PDV only when BGA assembly infrastructure is unavailable; ZHK offers superior signal integrity and thermal dissipation for production notebooks |
Compared with PCI1620GHK, PCI1620ZHK offers identical functionality in the same CROSTAR BGA package but with updated TI internal marking-no design impact. Versus PCI1620PDV, PCI1620ZHK delivers higher integration density, better thermal performance, and optimized high-speed PCI/CardBus signal routing for volume OEM deployments.

FAQ
What is the primary function of the PCI1620ZHK in a host system?
The PCI1620ZHK serves as a multifunction PCI bridge that manages two independent PC Card/CardBus sockets while integrating UltraMedia™ flash media and Smart Card controller logic. It handles card enumeration, power sequencing, interrupt routing, and protocol translation-enabling hot insertion/removal and seamless driver compatibility with existing ATA and ExCA stacks. The PCI1620ZHK eliminates the need for discrete controllers and external firmware loaders in notebook and embedded host designs.
Does the PCI1620ZHK support both 3.3-V and 5-V PC Cards?
Yes, the PCI1620ZHK supports mix-and-match operation of 5-V and 3.3-V 16-bit PC Cards alongside 3.3-V CardBus cards in either socket. Its integrated power-switch interface works with TI TPS2226 and TPS2228 dual power switches to independently control VCC for each socket. Voltage selection is managed through configuration registers and card-detect logic, ensuring safe insertion and proper signaling levels per card type.
Is the PCI1620ZHK pin-compatible with the Intel 82365SL–DF controller?
The PCI1620ZHK is ExCA register compatible with the Intel 82365SL–DF, meaning its configuration space, I/O-mapped registers, and interrupt behavior match exactly-allowing reuse of existing PC Card service software. However, it is not physically pin-compatible due to differing packages (BGA vs LQFP) and expanded signal sets (e.g., CLKRUN#, UltraMedia-specific pins). Software migration requires no changes; hardware replacement requires board redesign.
What role does Function 2 play in the PCI1620ZHK architecture?
Function 2 in the PCI1620ZHK is a dedicated firmware loader interface that enables the host to load program RAM with UltraMedia™-specific firmware for SmartMedia™, SD, MMC, Memory Stick™, and Smart Card operations. This function operates independently of Functions 0 and 1 (the socket controllers), allowing background firmware updates without disrupting active card operations. It uses a serial interface mapped to PCI configuration space and is essential for enabling the PCI1620ZHK's multi-format flash media capabilities.
How does the PCI1620ZHK handle power management in portable systems?
The PCI1620ZHK complies with PCI Bus Power Management Interface Specification 1.1 and supports D0–D3hot/D3cold states, CLKRUN# signaling, and programmable D3 status terminals. It coordinates with TI TPS2226/TPS2228 power switches to gate socket power and uses advanced filtering on card detect lines (90 µs noise immunity) to minimize false wake events. These features allow host systems to reduce overall platform power consumption during sleep or idle states while maintaining fast resume latency-critical for battery-powered notebooks and mobile HMIs.
