Product details
Overview
PCI1510PGEG4 from Texas Instruments is a single-slot PCI-to-CardBus bridge controller in 144-pin low-profile QFP (PGE) 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, integrated LDO-VR for 2.5-V core supply, and hot-swap–capable buffered card interface - deployed in notebook docking stations and legacy PC Card expansion systems.
For engineers reviewing the PCI1510PGEG4 datasheet, PCI1510PGEG4 pinout, PCI1510PGEG4 application, or PCI1510PGEG4 equivalent, this page delivers verified technical context on PCI/CardBus bridging, power management (ACPI/PME), socket control registers, serial EEPROM configuration, and interrupt routing options - all grounded in the SCPS071E data manual.
Technical Context
The PCI1510PGEG4 implements a pipelined, register-compatible bridge architecture that supports concurrent PCI master/slave operation and full 32-bit PCI cycles for CardBus transactions. Its internal buffering enables hot insertion/removal without external logic, while the integrated LDO-VR generates 2.5-V core voltage from a 3.3-V input - eliminating need for dual-supply design.
It provides two independent memory-mapped register sets: PCI Configuration Space (including Power Management Capability registers per PCI 2.2) and ExCA-compliant socket control registers (accessible via I/O or memory space). The controller supports serialized IRQ (IRQSER), parallel PCI/ISA interrupts, and five general-purpose I/Os for sideband signaling.

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 |
|---|---|---|---|
| TI PCI1410GZU | 209-pin PBGA (GVF/ZVF) package; identical register set and feature set - differs only in package and thermal performance. | Requires PCB redesign for larger footprint and different thermal pad layout; suited for higher-density layouts where QFP placement is constrained. | Select PCI1410GZU only when board space permits larger BGA and thermal management supports higher junction temperature. |
| Intel 82365SL-DF | No integrated LDO-VR; requires external 2.5-V supply; lacks serialized IRQ (IRQSER); lower maximum throughput (~90 Mbps). | Legacy BIOS/driver support is broader, but power design complexity increases due to dual-supply requirement and missing PME features. | Choose 82365SL-DF only for drop-in replacement in existing 82365SL-based designs where LDO-VR and IRQSER are unused. |
Compared with PCI1510PGEG4, PCI1410GZU offers identical functionality in a space-efficient BGA package but demands stricter layout controls, while 82365SL-DF trades integrated power management and throughput for wider legacy software compatibility - making PCI1510PGEG4 optimal for new designs prioritizing BOM reduction and power efficiency.

FAQ
What is the primary function of the PCI1510PGEG4?
The PCI1510PGEG4 is a PCI-to-CardBus bridge controller that enables host systems with a PCI bus to interface with 16-bit PC Cards and 32-bit CardBus peripherals. It implements ExCA-compliant socket control registers, supports hot insertion/removal, integrates an LDO-VR for 2.5-V core supply, and delivers >130 Mbps sustained throughput - making it ideal for notebook docking stations and embedded expansion modules. PCI1510PGEG4 handles voltage negotiation, card detection, power sequencing, and data translation without external logic.
Does the PCI1510PGEG4 require an external 2.5-V power supply?
No. The PCI1510PGEG4 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 regulator and simplifies power sequencing - confirmed in SCPS071E Section 3.8.1 and Table 3−10. External decoupling capacitors on VCC_CORE are still required per the datasheet recommendations. PCI1510PGEG4 thus reduces BOM count and improves system-level power efficiency.
Is the PCI1510PGEG4 pin-compatible with the Intel 82365SL-DF?
No - PCI1510PGEG4 is register-compatible but not pin-compatible with the Intel 82365SL-DF. While both devices share identical ExCA and PCI configuration register maps (enabling software compatibility), their physical packages differ: PCI1510PGEG4 uses a 144-pin PGE QFP, whereas 82365SL-DF uses a 128-pin PQFP. Pin assignments, power pin locations, and thermal pad structure are not interchangeable. PCI1510PGEG4 requires a dedicated PCB layout.
What interrupt signaling options does the PCI1510PGEG4 support?
The PCI1510PGEG4 supports four interrupt signaling modes: parallel PCI (INTA#), serialized PCI (IRQSER), parallel ISA (IRQx#), and serialized ISA (IRQSER). IRQSER enables daisy-chained interrupt handling across multiple sockets and supports ACPI wake events. Configuration is done via the Interrupt Line, Interrupt Pin, and General-Purpose Event Enable registers. These options allow flexible integration into both legacy x86 systems and modern low-pin-count embedded hosts. PCI1510PGEG4's interrupt flexibility is documented in Sections 3.7 and 4.23–4.24 of SCPS071E.
How does the PCI1510PGEG4 handle hot insertion and removal of PC Cards?
The PCI1510PGEG4 internally buffers all card signals - including address, data, and control lines - with overvoltage-tolerant I/O structures, enabling safe hot insertion and removal without external bus-hold or level-shifting components. Card presence is detected via CD1# and CD2# inputs, triggering socket event interrupts and initiating controlled power ramp-up/down sequences. This behavior is validated per PC Card Standard Rev. 7.2 and detailed in SCPS071E Sections 3.5.1 and 2.2. PCI1510PGEG4's integrated buffering ensures system stability during dynamic card swapping.
