The Texas Instruments PCI1620 is an integrated dual-socket PC Card controller, FlashMedia™ controller

(SmartMedia™ Card, MultiMediaCard, SD Card, Memory Stick™ card) and Smart Card controller.

The PCI1620 UltraMedia™ controller is a three-function PCI device compliant with PCI Local Bus Specification

2.2. Functions 0 and 1 provide two independent PC Card socket controllers compliant with PC Card Standard

8.0. Function 2 is the interface to load the PCI1620 program RAM with firmware. The PCI1620 provides features

that make it ideal for bridging between the PCI bus and PC Cards, and supports any combination of 16-bit,

CardBus, and UltraMedia PC Cards in the two sockets, powered at 5 V, 3.3 V, or 1.8 V as required.
