GENERAL DESCRIPTION

The Miniature Card is an expansion card that pro-
vides a low cost, low power, high-performance, small
form factor solution for data and file storage to the
portable, handheld market, which includes audio,
digital film, wireless, and PDA (Portable Digital
Assistant) applications.

Miniature cards can be easily "snapped" into the back
of an electronic system and can be readily removed
and replaced by end users. AMD's 3 V Flash Miniature
Cards are manufactured using AMD's industry leading
3.0 volt-only, single-power-supply Am29LV081 Flash

Memory device, ensuring high reliability and excellent
performance. The Miniature Card is less than 30% of
the size of a PCMCIA memory card. Applications
include digital voice recorders, pocket PCs and intelli-
gent organizers, smart cellular telephones, voice and
data messaging pagers, digital still cameras and por-
table instrumentation equipment.

The Miniature Card specification will be defined by
PCMCIA as of October 1997. The participating associ-
ation members include major Flash memory vendors
and leading consumer electronics OEMs. The goal of
the Miniature Card specification is to promote an open,

interoperable small-form-factor memory card standard.

t i o n , v i s i t t h e P C M C I A w e b s i t e a t

AMD Flash Miniature Cards can be read in either a
byte-wide or word-wide mode, which allows for flexible
integration into various system platforms. Compatibility
is assured at the hardware interface and software inter-
change specification.

The Miniature Card is also designed with low-cost and
rugged handling in mind. The card contains virtually no
control logic, which keeps cost and power consumption
to a minimum. The Miniature Card is packaged in a
sonic welded, stainless steel case that guarantees
durability, provides good ESD protection and ease of
handling.

The Miniature Card has extensive third-party support,
including socket and connector solutions, software

support from the major FTL software vendors, and
PCMCIA adapter solutions and programmer support.

AMD's Miniature Flash cards can be used for both code
and data storage. Since fast random access is pos-
sible, code can be directly executed from the card,
reducing the amount of system RAM required. In addi-
tion. AMD's Flash technology offers unsurpassed
endurance, data retention and reliability, eliminating
the need for complex error correction and defect man-
agement hardware and software. Each Flash sector
provides a minimum of 100,000 cycles, and a typical
card life of one million or more cycles.

DEFINITIONS

Table 1 lists the terms and definitions that may be used
in conjunction with Miniature Card specifications.

Table 1.

Miniature Card Definitions

Term

Meaning

AIS

Acronym for Attribute Information Structure. AIS is a Miniature Card specification for storing
Miniature Card attribute information.

ESD

Acronym for Electrostatic Discharge. ESD is part of the Miniature Card physical test.

FAT

Acronym for File Allocation Table. Using an FAT is a common method for managing files in a
DOS-based system.

Flash

A type of non-volatile memory that is both readable and writeable, but requires the media to
be erased before it is rewritten.

Host

Any system that incorporates a Miniature Card socket.

Insertion, Cold

User Perception: Insertion of the Miniature Card when the host is off.

Host State: The host would be either off or in sleep mode, no bus activity is occurring, the
host is non-operational by the user. The user inserts the Miniature Card and then presses a
button to turn the host on before the system is operational.

Insertion, Hot

User Perception: Insertion of a Miniature Card when the host is running.

Host State: The host would be in running mode, bus activity is occurring, the host is
operational by the user. The user inserts the card, the host recognizes it, and the host
continues to be operational. Note: Hot insertion may require buffering on the host system for
proper operation.

Insertion, Pseudo Hot

User Perception: Insertion of a Miniature Card when the host is running.

Host State: The host would be in running mode, bus activity is occurring, the host is
operational by the user. The user inserts the card, the host immediately powers off before the
Miniature Card makes contact with the host's internal bus. The user would then need to press
a button to turn the host on for it to become operational.

Interface Signals

Miniature Card signals that make connection through the 60-pad connector area.

JEDEC

Acronym for Joint Electronic Device Engineering Council.

Miniature Card Backside

The side of the Miniature Card that contains the latching mechanism. The backside is
opposite the frontside.

Miniature Card Bottomside

The side of the Miniature Card that contains the interface signals. The bottomside is opposite
the topside.

AmMCL00XA 3

P R E L I M I N A R Y

Miniature Card Frontside

The side of the Miniature Card that contains power, insertion, ground, voltage keys, and
alignment notch. The frontside is opposite the backside.

Miniature Card Topside

The side of the Miniature Card that contains the Miniature Card label. The topside is opposite
the bottomside.

PC Card

A memory or I/O card compatible with the PC Card Standard.

PC Card Adapter

The hardware that connects the Miniature Card 60 contact bus to the PC Card 68 pin bus.
This hardware can be mechanically implemented by following the PC Card Type II
specification.

Power/Insertion Signals

The three signals on the frontside of the Miniature Card that provide ground, power and early
detection of insertion.

Pull-Ups

Resistors used to ensure that signals do not float when no device is driving them.

Removal, Cold

User Perception: Removal of a Miniature Card when the host is off.

Host State: The host would either be off or in sleep mode, no bus activity is occurring, the
host is non-operational by the user. User would turn off the host, then remove the Miniature
Card and then press a button to turn the host on for it to become operational again.

Removal, Hot

User Perception: Removal of the Miniature Card when the host is running.

Host State: The host would be in running mode, bus activity is occurring, the host is
operational by the user. User removes the card, the host recognizes the event, and the host
continues to be operational.

Removal, Pseudo Hot

User Perception: Removal of the Miniature Card when the host is running.

Host State: The host would be in running mode, bus activity is occurring, the host is
operational by the user. User removes the card, the host recognizes the event, the host
immediately powers off before the Miniature Card removes contact with the host's internal
bus. The user would then need to press a button to turn the host on for it to be operational
again.

Sector

Usually 64 KBytes. In word mode, a sector is 64 Kwords.

Tuple

An element of the PC Card Standard CIS that provides card attribute information, and a link
to the next tuple in a string of tuples.

User Insertable

All Miniature Cards should be inserted into the host by the user without the need for any
special tools.

User Removable

This type of Miniature Card can be removed by the user without the need for any special
tools. It contains programs and data that users may want to switch often. The use of this type
of card is similar to a floppy disk.

User Non-Removable

This type of Miniature Card must be removed by the user with a special tool. It contains
memory upgrades or boot program that users switches only when they require an upgrade.
The use of this type of card is similar to a SIMM memory expansion or boot hard disk.

XIP

Acronym for eXecute-In-Place, which refers to code that executes directly from a Miniature
Card.
