Texas Instruments PCI1410APGEG4

Overview

The PCI1410APGEG4 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 power management, and integrates ExCA-compatible register sets for legacy software compatibility. It is used in notebook/desktop expansion slots for hot-pluggable I/O peripherals.

For engineers reviewing the PCI1410APGEG4 datasheet, PCI1410APGEG4 pinout, PCI1410APGEG4 application, or PCI1410APGEG4 equivalent, key selection criteria include CardBus/16-bit PC Card dual-mode support, integrated power-switch interface (TPS2211 compatible), ExCA register mapping, suspend/resume timing compliance, and PCI master/slave configurability.

Technical Context

The PCI1410APGEG4 implements a PCI-to-CardBus bridge with full ExCA register compatibility, enabling seamless integration with legacy PC Card drivers. It supports distributed DMA (DDMA) with two independent channels and provides hardware-level CardBus socket event detection including card insertion/removal, voltage sense, and ring indicator.

Its internal architecture includes a configurable PCI interface (master or slave), integrated serial bus (I²C-compatible) for EEPROM configuration, programmable interrupt subsystem with parallel IRQ/PCI/serialized IRQSER outputs, and dedicated power-management logic supporting ACPI S3/S4 states and PCI PME signaling.

Key Specifications

Pinout & Package

The PCI1410APGEG4 is housed in a 144-pin LQFP (GGU package), measuring 20 mm × 20 mm × 1.4 mm, with 0.5 mm pitch and exposed thermal pad. Pin assignments are defined across three functional groups: PCI interface (AD[31:0], C/BE[3:0]#, PAR, FRAME#, TRDY#, etc.), PC Card interface (SA[23:0], SD[15:0], OE#, WE#, CD1#, CD2#, VCC/VPP, etc.), and system control (RESET#, CLK, INTA#, IRQ, SCLK, SDA, etc.).

FAQ

What is the primary function of the PCI1410APGEG4?

The PCI1410APGEG4 is a single-chip PCI-to-PC Card bridge controller that enables host systems to interface with both 16-bit PC Cards and 32-bit CardBus peripherals. It handles protocol translation, power management, card detection, ExCA register mapping, and PCI bus mastering - all within one device. Its design eliminates the need for discrete logic or multiple controllers in notebook and desktop expansion architectures.

Does the PCI1410APGEG4 support CardBus operation at 33 MHz?

Yes, the PCI1410APGEG4 supports full 32-bit CardBus operation at 33 MHz, compliant with PC Card Standard Release 5.0. It meets all timing requirements for CardBus command active cycle time (t_c(A)), address setup/hold times, and interface control signal synchronization - verified across temperature and voltage ranges per datasheet Section 8.6.

How does the PCI1410APGEG4 handle dual-voltage PC Cards (3.3 V and 5 V)?

The PCI1410APGEG4 supports automatic voltage detection and switching for 16-bit PC Cards via dedicated VCC/VPP terminals and integrated power-switch control logic. It interfaces directly with TI TPS2211 to sequence 3.3 V and 5 V supplies safely, monitor fault conditions, and assert PWR_FAULT to prevent damage during misinsertion or overcurrent events.

Is the PCI1410APGEG4 compatible with legacy ExCA-based software drivers?

Yes, the PCI1410APGEG4 implements the complete ExCA register set - including Power Control, Card Status Change, Socket Event, and Memory/I/O Window registers - at standard offsets. This ensures binary compatibility with existing PC Card drivers written for Intel 82365SL-class controllers, enabling plug-and-play integration without driver modification.

What packaging and thermal specifications apply to the PCI1410APGEG4?

The PCI1410APGEG4 uses a 144-pin LQFP (GGU package) with 20 mm × 20 mm body, 0.5 mm pitch, and exposed thermal pad. Its thermal resistance (θ_JA) is 32°C/W, and it operates across –40°C to +85°C ambient. The package is RoHS-compliant and lead-free, qualified per JEDEC J-STD-020 moisture sensitivity level 3.
