Price for ONE device

DESCRIPTION

The Texas Instruments PCI1520, a 208-terminal dual-slot CardBus controller designed to meet the PCI Bus Power Management Interface Specification for PCI to CardBus Bridges, is an ultralow-power high-performance PCI-to-CardBus controller that supports two independent card sockets compliant with the PC Card Standard (rev. 7.1). The PCI1520 provides features that make it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The 1997 PC Card Standard retains the 16-bit PC Card specification defined in PCI Local Bus Specification and defines the new 32-bit PC Card, CardBus, capable of full 32-bit data transfers at 33 MHz. The PCI1520 supports any combination of 16-bit and CardBus PC Cards in the two sockets, powered at 5 V or 3.3 V, as required.
The PCI1520 is compliant with the PCI Local Bus Specification, and its PCI interface can act as either a PCI master device or a PCI slave device. The PCI bus mastering is initiated during CardBus PC Card bridging transactions. The PCI1520 is also compliant with PCI Bus Power Management Interface Specification (rev. 1.1).

FEATURES

• The PCI1520 supports the following features:
• A 208-terminal low-profile QFP (PDV) package
• 2.5-V core logic and 3.3-V I/O with universal PCI interfaces compatible with 3.3-V and 5-V PCI signaling environments
• Integrated low-dropout voltage regulator (LDO-VR) eliminates the need for an external 2.5-V power supply
• Mix-and-match 5-V/3.3-V 16-bit PC Cards and 3.3-V CardBus Cards
• Two PC Card or CardBus slots with hot insertion and removal
• Serial interface to TI™ TPS222X dual-slot PC Card power switch
