Product details
Overview
PCI1620GHK from Texas Instruments is a dual-socket PC Card and UltraMedia™ controller IC implementing three PCI functions: two independent PC Card socket controllers (Functions 0 & 1) compliant with PC Card Standard 8.0, and a firmware loader interface (Function 2). It supports 16-bit PC Cards, CardBus, SmartMedia™, SD, MultiMediaCard, Memory Stick™, and Smart Card adapters at 1.8-V/3.3-V/5-V, with 5 PCI memory windows and 2 I/O windows per socket, and integrated 1.8-V core voltage regulation.
For engineers reviewing the PCI1620GHK datasheet, PCI1620GHK pinout, PCI1620GHK application, or PCI1620GHK equivalent, key selection considerations include ExCA register compatibility with Intel 82365SL–DF, support for serialized IRQ and PCI CLKRUN, AC'97-compliant power management, serial EEPROM-based subsystem ID loading, and hot insertion/removal of mixed-voltage cards in embedded industrial PCs and legacy mobile docking systems.
Technical Context
The PCI1620GHK implements a PCI-to-CardBus bridge architecture with separate configuration spaces per socket and full 32-bit PCI host access to 8-/16-/32-bit cards. Its pipeline buffering and posted-write capability enable sustained 132-MBps burst transfers across both PCI and CardBus buses.
It integrates an AC'97-compliant power management interface supporting D0–D3 states, programmable D3 status terminal, and ACPI-compliant general-purpose event registers. The device uses a three-terminal serial interface compatible with TI TPS2226/TPS2228 dual power switches for socket power control.

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 |
|---|---|---|---|
| PCI1520GHK | Single-socket controller; lacks Function 2 firmware loader; no SmartCard support; only 3 memory windows per socket | Suitable for cost-sensitive single-slot designs without SmartCard or UltraMedia requirements | Select when system requires only one PC Card slot and does not need SmartCard or SD/SmartMedia functionality |
| PCI1621GHK | Enhanced revision with improved thermal performance; adds PCIe-to-PCI bridge mode; same pinout and register set | Required for new designs targeting extended temperature range (–40°C to 85°C) or PCIe host interface migration path | Select for new industrial designs requiring longer lifecycle support and backward-compatible upgrade from PCI1620GHK |
Compared with PCI1620GHK, PCI1520GHK reduces socket count and feature set for lower-cost single-slot applications, while PCI1621GHK maintains full functional equivalence with added thermal robustness and PCIe bridge capability - making it the only viable long-term replacement for new designs where PCI1620GHK is obsolete.

FAQ
What is the package type and pin count of the PCI1620GHK?
The PCI1620GHK uses a 209-ball Microstar BGA package with drawing code GHK, 0.8-mm ball pitch, and 15 mm × 15 mm body size. This package is confirmed in TI's SLLA234 datasheet and packaging addendum (2008). All 209 balls are assigned - including 13 multifunction terminals, 4 general-purpose event inputs, and dedicated CLKRUN#, CD#, and LED control signals. No alternate packages exist for this specific orderable part number.
Is the PCI1620GHK pin-compatible with the PCI1620PDV LQFP variant?
No, the PCI1620GHK is not pin-compatible with the PCI1620PDV. The GHK variant uses a 209-ball BGA package, while the PDV variant uses a 208-pin LQFP package with different pin assignments, thermal pad configuration, and signal routing. Although both share identical register-level functionality and firmware, PCB layout, thermal design, and assembly processes are not interchangeable between these packages.
Does the PCI1620GHK support SmartCard functionality, and how is it implemented?
Yes, the PCI1620GHK supports SmartCard functionality through Function 2 - a dedicated interface for loading program RAM with firmware that enables SmartCard protocol handling. TI provides a qualified SmartCard driver for UltraMedia-based adapters. The controller manages SmartCard power, clock, and I/O signals natively, eliminating need for external SmartCard controller ICs. SmartCard operation coexists with PC Card and UltraMedia functions on shared PCI resources.
What power management features does the PCI1620GHK provide for ACPI-compliant systems?
The PCI1620GHK implements full ACPI 1.0 compliance via four programmable general-purpose event registers, a dedicated D3 status terminal, and support for PCI Power Management Interface Specification 1.1. It enables D0–D3 power states, allows wake-on-card-insertion events, and supports CLKRUN#-driven clock gating. These features let host OSes manage sleep/wake transitions without requiring custom power sequencers or external PMIC coordination.
Can the PCI1620GHK be used with modern operating systems like Windows 10 or Linux kernel 5.x?
Yes, the PCI1620GHK can operate under Windows 10 and Linux kernel 5.x, but only with legacy driver support. Its ExCA register compatibility with Intel 82365SL–DF ensures recognition by standard PC Card socket drivers. However, native UltraMedia (SD/SmartMedia) and SmartCard functionality require vendor-provided drivers - TI's last qualified Windows driver was for Windows XP/7, and mainline Linux support is limited to basic CardBus enumeration without flash media acceleration.
