Texas Instruments PCI1410AGHK

Overview

The PCI1410AGHK from Texas Instruments is a PCI-to-PC Card bridge controller supporting both 16-bit PC Card and 32-bit CardBus sockets, compliant with PCI Local Bus Specification Rev 2.2 and PC Card Standard Release 5.0. It operates at 33 MHz PCI clock, supports dual-voltage (3.3 V/5 V) card detection and power switching via integrated TPS2211 interface, and implements full ExCA register compatibility for legacy driver support.

For engineers reviewing the PCI1410AGHK datasheet, PCI1410AGHK pinout, PCI1410AGHK application, or PCI1410AGHK equivalent, key selection criteria include CardBus/16-bit PC Card dual-mode operation, PCI bus mastering capability, ExCA register mapping fidelity, and integrated serial EEPROM configuration support for system initialization.

Technical Context

The PCI1410AGHK implements a dual-bus architecture: a 32-bit 33 MHz PCI interface on one side and a configurable PC Card socket interface supporting either 16-bit ISA-style or 32-bit CardBus protocols on the other. It includes dedicated hardware for CardBus power management (PME, D0–D3 states), Suspend Mode logic, and Ring Indicate (RI_OUT) signaling per PCMCIA specification.

Its internal register map fully mirrors ExCA (PCMCIA Externally Configurable Architecture) registers at memory- and I/O-mapped offsets, enabling drop-in compatibility with existing PC Card drivers. The device integrates a serial bus controller (I²C-compatible) for external EEPROM-based configuration of critical registers including System Control, Socket Control, and Power Management registers.

Key Specifications

Pinout & Package

The PCI1410AGHK is housed in a 256-ball GHS (GHK) plastic ball grid array package. Pin assignments are defined across four functional groups: PCI interface signals (AD[31:0], C/BE[3:0]#, PAR, FRAME#, IRDY#, TRDY#, STOP#, DEVSEL#, PERR#, SERR#), PC Card interface signals (SA[23:0], SD[15:0], OE#, WE#, CE1#, CE2#, IORD#, IOWR#, RESET#, BVD1/BVD2, VPP1/VPP2), power/ground terminals (VCC_PCI, VCC_CORE, VCC_IO, VCC_3V3, VCC_5V, GND), and control/serial bus signals (SCL, SDA, IRQSER, SMI#, RI_OUT, CLKRUN#, TPS2211 control lines).

FAQ

What is the primary function of the PCI1410AGHK?

The PCI1410AGHK is a single-chip PCI-to-PC Card bridge controller that enables connection of both 16-bit PC Cards and 32-bit CardBus devices to a PCI bus. It implements full ExCA register compatibility, supports PCI bus mastering, and handles dual-voltage card detection and power switching - all within one integrated solution for notebook, docking, and embedded host systems.

Does the PCI1410AGHK support CardBus devices operating at 33 MHz?

Yes, the PCI1410AGHK supports CardBus devices running at the full 33 MHz clock rate, delivering up to 132 MB/s theoretical bandwidth. Its internal timing logic complies with PC Card Standard Release 5.0 requirements for CardBus cycle timing, including setup/hold times and command-active durations measured over the recommended operating conditions (0 °C to 70 °C, 3.3 V ± 0.3 V).

How does the PCI1410AGHK handle power management for inserted PC Cards?

The PCI1410AGHK implements comprehensive power management per ACPI 1.0 and PCI PM 1.1 specifications. It supports D0–D3 device states, generates PME# signals for wake events, and controls external TPS2211 load switches to sequence 3.3 V and 5 V power rails. Suspend Mode retains socket context and enables wake-on-card-insert or wake-on-Ring Indicate (RI_OUT) without host CPU involvement.

Can the PCI1410AGHK be configured without external firmware or BIOS updates?

Yes - the PCI1410AGHK includes an I²C-compatible serial bus interface that reads initialization values from an external EEPROM at power-on. This allows configuration of ExCA register defaults (e.g., memory window bases, interrupt routing, socket control bits) without modifying system BIOS or host driver code, simplifying integration and field updates.

Is the PCI1410AGHK pin-compatible with earlier TI PCI1410 variants?

No - the PCI1410AGHK uses the GHK (256-ball GHS) package, whereas earlier PCI1410A versions such as PCI1410APGE use the 256-pin PGE LQFP package. While register-level functionality and electrical specifications are identical, the GHK BGA footprint and ball assignment differ significantly from PGE; PCB layout is not interchangeable.
