The voltage range for Memory Stick cards is 2.7 to 3.6 V, and the clock speed can be up to 20 MHz. Memory Stick
cards use the FAT file system to allow for easy communication with PCs.
There are two types of Memory Stick cards, the standard Memory Stick and the MagicGate Memory Stick. MagicGate
technology provides security to Memory Stick cards so that they can be used to store and protect copyrighted data.
Memory Stick cards are primarily used to store still images, moving images, voice and music. As such, they are used
in a variety of devices, including portable music players, digital cameras, and digital picture frames.
3.5.4
Smart Card
Smart Cards, also called integrated circuit cards or ICCs, are the same size as a credit card, and they contain an
embedded microprocessor chip. Smart Cards can either have contacts or be contactless. In addition, there are both
asynchronous and synchronous versions of Smart Cards with contacts. Within this data manual, all uses of the term
Smart Card refers only to asynchronous Smart Cards with contacts.
Smart Cards contain eight contacts; however, two of the contacts are reserved for future use and are not included
in the UltraMedia interface. Smarts Cards can be either 5-V or 3-V cards; however, all 3-V cards are designed to work
also at 5 V.
The primary use of Smart Cards is in security-related applications. They are also used in credit cards, debit systems,
and identification systems.

PC Card Applications
The PCI6x20 device supports all the PC Card features and applications as described below.
Card insertion/removal and recognition per the
PC Card Standard
(release 8.0)
Speaker and audio applications
LED socket activity indicators
PC Card controller programming model
CardBus socket registers
3.6.1
PC Card Insertion/Removal and Recognition
The
PC Card Standard
(release 8.0) addresses the card-detection and recognition process through an interrogation
procedure that the socket must initiate on card insertion into a cold, nonpowered socket. Through this interrogation,
card voltage requirements and interface (16-bit versus CardBus) are determined.
The scheme uses the card-detect and voltage-sense signals. The configuration of these four terminals identifies the
card type and voltage requirements of the PC Card interface.
3.6.2
Low Voltage CardBus Card Detection
The card detection logic of the PCI6x20 device includes the detection of Cardbus cards with V
CC
= 3.3 V and
V
PP
= 1.8 V. The reporting of the 1.8-V CardBus card (V
CC
= 3.3 V, V
PP
= 1.8 V) is reported through the socket present
state register as follows based on bit 10 (12V_SW_SEL) in the general control register (PCI offset 86h, see Section
4.31):
If the 12V_SW_SEL bit is 0 (TPS2228 is used), then the 1.8-V CardBus card causes the 3VCARD bit in the
socket present state register to be set.
If the 12V_SW_SEL bit is 1 (TPS2226 is used), then the 1.8-V CardBus card causes the XVCARD bit in
the socket present state register to be set.
3.6.3
UltraMedia Card Detection
The PCI6x20 device is capable of detecting all the UltraMedia devices defined by the PCMCIA
Proposal 0262
–
MultiMedia Cards, Secure Digital, Memory Stick devices, and Smart Card devices. The detection of these devices
