Texas Instruments PCI6411ZHK

Overview

PCI6411ZHK from Texas Instruments is a single-socket UltraMedia PC Card and flash media controller IC supporting PC Card, SD, MMC, Memory Stick/PRO, SmartMedia, and xD interfaces. It features 1.5-V core logic with 3.3-V I/O, PCI Local Bus Specification 2.3 compliance, and integrated ExCA-compatible register mapping for CardBus bridge functionality in portable computing systems.

For engineers reviewing the PCI6411ZHK datasheet, PCI6411ZHK pinout, PCI6411ZHK application, or PCI6411ZHK equivalent, key selection considerations include its BGA-288 ZHK package, PCI-to-CardBus bridge architecture, support for hot insertion/removal, serialized IRQ handling, and power management states D0–D3 in battery-powered notebook platforms.

Technical Context

The PCI6411ZHK implements a PCI-to-CardBus bridge with dedicated flash media interface logic and single-socket UltraMedia controller functionality. It maps ExCA-compatible registers into memory or I/O space and supports subtractive decoding, VGA/palette memory access, and LED activity terminals.

It complies with PCI Bus Power Management Interface, ACPI 2.0, PC Card Standard 8.1, and Intel 82365SL-DF register compatibility. The device operates with 1.5-V core voltage generated internally from 3.3-V supply and supports SUSPEND, LOCK, and CLKRUN protocols on the PCI bus.

Key Specifications

Pinout & Package

PCI6411ZHK is housed in a 288-pin MicroStar BGA (ZHK) package with 1.0-mm ball pitch and 17 × 17 mm body size. Thermal and mechanical data per TI SLLA243 and Package Option Addendum (Feb 2008).

FAQ

What is the primary function of the PCI6411ZHK?

The PCI6411ZHK is a single-socket UltraMedia PC Card and flash media controller that bridges PCI bus signals to CardBus peripherals while managing SD, MMC, Memory Stick/PRO, SmartMedia, and xD storage devices. Its core function is to integrate bridge logic, flash media control, and power management into one BGA-288 IC for space-constrained portable systems. The PCI6411ZHK does not support Smart Card interfaces - that capability is reserved for the PCI6611ZHK variant.

Does the PCI6411ZHK support Smart Card functionality?

No, the PCI6411ZHK does not support Smart Card functionality. Per TI's SLLA243 documentation, the PCI6411ZHK is explicitly defined as an "integrated single-socket UltraMedia PC Card controller and flash media controller" - omitting Smart Card controller logic present in the PCI6611ZHK and PCI6621 variants. This omission reduces silicon area and power consumption, aligning with its target use in SD-centric, non-secure-authentication applications.

What package type and pin count does the PCI6411ZHK use?

The PCI6411ZHK uses a 288-ball MicroStar BGA package with ZHK suffix, featuring a 1.0-mm ball pitch and 17 × 17 mm body size. This package is documented in TI's Package Option Addendum (Feb 2008) and confirmed in the SLLA243 datasheet. It is mechanically and thermally distinct from the GHK variant, though both share identical pin count and signal assignment.

Is the PCI6411ZHK still in production?

No, the PCI6411ZHK is marked OBSOLETE by Texas Instruments per official packaging information. TI discontinued production and no longer recommends it for new designs. However, Aetrix Electronics maintains legacy supply channels and supports lifecycle management for existing programs relying on the PCI6411ZHK in deployed industrial, medical, and POS equipment.

How does the PCI6411ZHK handle power management in portable systems?

The PCI6411ZHK implements full PCI power management with hardware support for D0–D3 states, automatic device power-down during suspend, and internal 1.5-V core regulation from 3.3-V supply. It also supports SUSPEND, CLKRUN, and LOCK protocols on the PCI bus - enabling coordinated low-power operation with host chipset and OS power managers in battery-powered notebooks and tablets using the PCI6411ZHK.
