Texas Instruments PCI1510RGVF

Overview

PCI1510RGVF from Texas Instruments is a 253-terminal NFBGA CardBus-to-PCI bridge controller supporting single-slot 16-bit PC Card and 32-bit CardBus operation at 33 MHz, with 2.5-V core/3.3-V I/O, integrated LDO-VR, and Intel 82365SL register compatibility for notebook/desktop host systems.

For engineers reviewing the PCI1510RGVF datasheet, PCI1510RGVF pinout, PCI1510RGVF application, or PCI1510RGVF equivalent, key selection criteria include CardBus/PCI bridging throughput (>130 Mbps), hot-insertion support, ExCA register mapping, universal 3.3-V/5-V signaling compatibility, and programmable CLKRUN output for power-managed systems.

Technical Context

The PCI1510RGVF implements a pipelined data path architecture enabling sustained burst transfers between PCI and CardBus domains, with independent buffering for hot insertion/removal and full 32-bit PCI cycle support for 8-/16-/32-bit card access. It operates as both PCI master (during CardBus transactions) and slave, compliant with PCI Local Bus Spec Rev 2.2 and PCI Bus Power Management Interface Spec Rev 1.1.

It integrates an internal ring oscillator, five general-purpose I/Os, socket activity LED control, and supports multiple interrupt configurations including parallel/serialized PCI and ISA. The device maps ExCA-compatible registers into memory and I/O space and interfaces directly with TI TPS2211A power switch for slot-level power control.

Key Specifications

Pinout & Package

PCI1510RGVF is housed in a 253-terminal NFBGA package per MicroStar BGA GVF drawing. Pinout information is defined in TI SLLA230 (June 2006) and includes dedicated terminals for PCI bus signals (AD[31:0], C/BE[3:0]#, PAR, FRAME#, IRDY#, TRDY#, STOP#, DEVSEL#, PERR#, SERR#), CardBus signals (CD1#, CD2#, VCC, VPP, OE#, WE#, BVD1#, BVD2#), ExCA registers, CLKRUN, LED control, and five general-purpose I/Os.

FAQ

What is the primary function of the PCI1510RGVF?

The PCI1510RGVF is a single-slot CardBus-to-PCI bridge controller that enables communication between a PCI host bus and a 32-bit CardBus or 16-bit PC Card socket. It provides full ExCA register compatibility, pipelined data transfer, and integrated power regulation. The PCI1510RGVF supports hot insertion/removal and operates at up to 33 MHz with >130 Mbps throughput, making it suitable for notebook and docking station applications.

Does the PCI1510RGVF require an external 2.5-V power supply?

No, the PCI1510RGVF includes an integrated low-dropout voltage regulator (LDO-VR) that generates its 2.5-V core supply from the 3.3-V input, eliminating the need for an external 2.5-V rail. This integration reduces bill-of-materials count and simplifies PCB layout. The PCI1510RGVF still requires clean 3.3-V I/O supply and proper decoupling, as specified in TI SLLA230.

Is the PCI1510RGVF pin-compatible with Intel 82365SL controllers?

The PCI1510RGVF is register-compatible-not pin-compatible-with Intel 82365SL-DF and 82365SL ExCA controllers. Its 253-terminal NFBGA (GVF) package differs physically from Intel's PLCC or PQFP packages. However, software drivers and BIOS initialization routines written for Intel 82365SL can be reused with PCI1510RGVF due to identical ExCA register mapping and functional behavior.

What power management features does the PCI1510RGVF support?

The PCI1510RGVF complies with the PCI Bus Power Management Interface Specification Rev 1.1 and supports multiple low-power modes, including D1/D2/D3 states, CLKRUN#-controlled clock gating, and suspend/resume signaling (SUSPEND#, CCLKRUN#). It also includes an internal ring oscillator for autonomous timing during low-power states. These features allow the PCI1510RGVF to meet ACPI requirements in mobile platforms without external PMU coordination.

Why is the PCI1510RGVF marked as OBSOLETE in TI's packaging documentation?

The PCI1510RGVF is marked OBSOLETE by Texas Instruments because it was discontinued for new designs after June 2006, reflecting the industry-wide transition from PC Card/CardBus to ExpressCard and USB-based peripheral interfaces. While no longer in production, Aetrix Electronics maintains legacy supply channels and supports ongoing manufacturing for qualified industrial and embedded programs requiring this specific bridge controller.
