Texas Instruments PCI1410AZGU

Overview

PCI1410AZGU from Texas Instruments is a PCI-to-PC Card controller supporting single-slot 16-bit PC Card and 32-bit CardBus interfaces with 3.3-V core logic, 5-V/3.3-V mixed-voltage card compatibility, five PCI memory windows, two I/O windows for PC Card, and pipelined architecture enabling >130 Mbit/s sustained throughput between CardBus and PCI buses in notebook/desktop host systems.

For engineers reviewing the PCI1410AZGU datasheet, PCI1410AZGU pinout, PCI1410AZGU application, or PCI1410AZGU equivalent, key selection considerations include ExCA register compatibility with Intel 82365SL, support for D3hot/D3cold wake, programmable CLKRUN output, socket-activity LED control, and distributed DMA (DDMA) capability for embedded PC Card bridge designs.

Technical Context

The PCI1410AZGU implements a register-compatible ExCA interface mapped in both memory and I/O space, supports parallel PCI/ISA IRQ and serialized ISA/PCI interrupts, and provides independent buffering for hot insertion/removal without external circuitry. Its pipelined data-path logic enables full 32-bit PCI cycles to access 8-/16-/32-bit cards while accepting fast-posted writes to improve bus utilization.

It operates as either PCI master or slave, initiates bus mastering during 16-bit PC Card DMA or CardBus bridging, and complies with PCI Bus Power Management Interface Specification for PCI-to-CardBus bridges. Internal ring oscillator and advanced submicron CMOS process enable low-power operation at up to 33 MHz PCI clock rate.

Key Specifications

Pinout & Package

FAQ

What is the primary function of the PCI1410AZGU in a host system?

The PCI1410AZGU serves as a PCI-to-PC Card bridge controller, enabling communication between a PCI host bus and a single-slot 16-bit PC Card or 32-bit CardBus socket. It handles protocol translation, voltage level adaptation, ExCA register mapping, and DMA coordination. The PCI1410AZGU integrates all necessary logic to support hot insertion/removal, power management states (including D3hot/D3cold wake), and mixed-voltage card operation-eliminating need for external buffer or interface ICs in compliant designs.

Does the PCI1410AZGU support both 16-bit PC Cards and 32-bit CardBus cards?

Yes, the PCI1410AZGU natively supports both 16-bit PC Cards and 32-bit CardBus cards. It provides five PCI memory windows and two I/O windows for the 16-bit PC Card socket, plus two additional I/O and two memory windows dedicated to the CardBus socket. The device maintains full compatibility with the PC Card Standard and enables mix-and-match operation of 5-V and 3.3-V cards, with internal buffering ensuring safe hot insertion and removal for both types without external components.

Is the PCI1410AZGU pin-compatible with Intel 82365SL controllers?

The PCI1410AZGU is register-compatible-not pin-compatible-with the Intel 82365SL-DF and 82365SL ExCA controllers. Its ExCA registers are mapped identically in memory and I/O space, allowing reuse of existing drivers and BIOS code. However, physical pinout differs due to distinct packaging (144-ball GGU BGA vs. Intel's PLCC/QFP packages) and enhanced feature set (e.g., CLKRUN#, LED control, additional GPIOs). Board redesign is required, but software migration is simplified.

What power management features does the PCI1410AZGU support?

The PCI1410AZGU supports PCI Bus Power Management Interface Specification for PCI-to-CardBus bridges, including full compliance with D3hot and D3cold device power states. It enables wake events from both states via card-detect or system interrupts. Additional low-power capabilities include programmable CLKRUN# output to gate PCI clock during idle, internal ring oscillator for autonomous timing, and multiple sleep modes coordinated with host power management firmware-reducing overall system power consumption in portable and embedded applications using PCI1410AZGU.

What package type is used for the PCI1410AZGU, and what are its key mechanical dimensions?

The PCI1410AZGU uses a 144-terminal MicroStar BGA™ (GGU) package with 0.8-mm ball pitch, 12.0 mm × 12.0 mm body size, and JEDEC MO-220 compliance. Ball grid layout is 12 × 12, with corner balls designated A1 and P12. The package features a coplanarity of ≤0.10 mm and moisture sensitivity level (MSL) rating of Level-3 (220°C peak reflow, 168-hour floor life). This GGU package is distinct from the PGE QFP variant and requires BGA-specific PCB layout and assembly practices for reliable deployment of PCI1410AZGU.
