Product details
Overview
PCI1510PGE from Texas Instruments is a single-slot PCI-to-CardBus bridge controller in a 144-terminal low-profile QFP package, supporting both 16-bit PC Cards and 32-bit CardBus cards at 3.3 V or 5 V. It implements full PCI 2.2 compliance, ExCA register compatibility with Intel 82365SL-DF/SL, and integrated LDO-VR for 2.5-V core supply. Used in notebook/desktop add-in cards for PCMCIA expansion.
For engineers reviewing the PCI1510PGE datasheet, PCI1510PGE pinout, PCI1510PGE application, or PCI1510PGE equivalent, this page delivers verified technical context on hot-swap support, burst-mode throughput (>130 Mbps), PCI/ISA interrupt routing options, serial EEPROM configuration, and socket-level power management - all critical for legacy PC Card interface design and migration.
Technical Context
The PCI1510PGE integrates a pipelined 32-bit data path enabling full 32-bit PCI cycles to access 8-/16-/32-bit cards, with internal buffering for hot insertion/removal without external logic. Its ExCA-compatible register set maps into both memory and I/O space, supporting legacy PC Card software stacks.
It features dual power domains (2.5-V core / 3.3-V I/O), an internal ring oscillator, programmable CLKRUN output, and five general-purpose I/Os. Power management includes Suspend Mode, PCI PME signaling, ACPI 1.1 support, and CardBus-specific power control via TPS2211A interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Intel 82365SL-DF | Same ExCA register map and 144-pin QFP package; lacks integrated LDO-VR and internal ring oscillator | Requires external 2.5-V supply and separate oscillator circuit - higher BOM cost and layout complexity | Choose when strict Intel reference design compliance is mandated and external power/oscillator resources are available |
| Texas Instruments PCI1520PGE | Enhanced version with dual-slot support, additional memory windows, and improved thermal performance; otherwise register- and pin-compatible | Supports two independent CardBus sockets - suitable for multi-peripheral carrier boards but over-specified for single-slot use | Choose only if future dual-slot expansion is planned; otherwise PCI1510PGE offers optimal cost/performance for single-socket designs |
Compared with Intel 82365SL-DF, PCI1510PGE reduces system-level power design effort via integrated LDO-VR; compared with PCI1520PGE, it delivers identical single-slot functionality at lower unit cost and smaller footprint - making it the most efficient choice for cost-sensitive, space-constrained notebook add-in cards.

FAQ
What is the primary function of the PCI1510PGE in a system design?
PCI1510PGE serves as a PCI-to-CardBus bridge controller, enabling host systems with a PCI bus to interface with 16-bit PC Cards and 32-bit CardBus peripherals. It handles protocol translation, voltage domain isolation, hot-swap sequencing, and ExCA register mapping - all within a single 144-pin QFP package. The PCI1510PGE replaces discrete logic or FPGA-based bridges in legacy expansion applications.
Does PCI1510PGE require an external 2.5-V power supply?
No. PCI1510PGE integrates a low-dropout voltage regulator (LDO-VR) that generates its 2.5-V core supply from the 3.3-V I/O rail. This eliminates the need for an external 2.5-V source, simplifying power design and reducing bill-of-materials cost. The PCI1510PGE datasheet confirms this in Section 3.8.1 and Table 3−10.
Is PCI1510PGE pin-compatible with Intel 82365SL-DF?
Yes. PCI1510PGE uses the same 144-pin low-profile QFP (PGE) package and maintains identical pinout and signal assignment as the Intel 82365SL-DF, as documented in TI's SCPS071E manual Section 2.1 and Table 2−1. This allows direct PCB replacement in existing 82365SL-DF layouts without redesign.
How does PCI1510PGE support hot insertion and removal of PC Cards?
PCI1510PGE provides internal 3-state bidirectional buffering on all card-facing signals, eliminating the need for external bus switches. It monitors CD1# and CD2# inputs to detect card presence, sequences power delivery via TPS2211A interface, and manages ExCA status registers to notify the host OS. These functions are implemented in hardware per Section 3.5.1 of the PCI1510PGE datasheet.
What interrupt signaling options does PCI1510PGE support?
PCI1510PGE supports four interrupt modes: parallel PCI (INTA#), serialized PCI (IRQSER), parallel ISA (IRQ3–IRQ7), and serialized ISA (IRQSER). Configuration is done via the Interrupt Line and Interrupt Pin registers (Sections 4.23–4.24) and the ExCA Interrupt and General Control Register (Section 5.4). This flexibility allows integration into diverse legacy and modern host architectures.
