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,

Erase Operations
The AMD Flash Miniature Card is organized as an
array of individual devices. Each Am29LV081 device
contains sixteen 64 KByte sectors, for a total of 1 Mbyte
of memory space per device.
Flash technology allows any logical “1” data bit to be pro-
grammed to a logical “0”. The only way to reset bits to a
logical “1” is to erase that entire memory sector or
memory device. Once a memory sector or memory
device is erased, any address location may be pro-
grammed. Two or more devices may be erased concur-
rently when additional ICC current is supplied to the card.
However, erasing more than two devices concurrently is
not typical in battery-powered applications, but may take
place during procedures such as card testing.
Erase operations can be performed in several ways:
s Erase a single sector or multiple sectors in a device
s Erase a sector pair
s Erase multiple device pairs*
s Erase the entire card*
* This operation is only feasible in solutions capable of
supplying more than the specified miniature card
supply current requirement (150mA) per system. Each
AMD Flash memory device pair can accept a
maximum of 120mA supply current.
The common memory space data contents are altered
in a similar manner to writing to individual Flash
memory devices. An on-card address decoder acti-
vates the appropriate Flash device in the memory
array. Each device internally latches address and data
during write cycles. Refer to Table 4.
Standby Mode
The AMD flash devices are designed to accommodate
low standby power consumption. In order to achieve
standby mode, the CE# line must be deselected. In
addition, while in the standby mode, data I/O pins
remain in the high impedance state independent of the
voltage level applied to the OE# input. See the DC
Characteristics section for more details on Standby
Modes.
Deselecting CE# (CE# and RESET# = VCC ± 0.3 V)
puts the device into the ICC3 standby mode. If the
device is deselected during an Embedded Algorithm
operation, it continues to draw active power (ICC2) prior
to entering the standby mode, until the operation is
complete. When the device is again selected (CE# =
VIL), active operations occur in accordance with the
AC timing specifications.
Automatic Sleep Mode
Advanced power management features such as the
automatic sleep mode minimize Flash device energy
consumption. This is extremely important in bat-
tery-powered applications. The AMD memory devices
automatically enable the low-power, automatic sleep
mode when addresses remain stable for 300 ns. Auto-
matic sleep mode is independent of the CE#, WE#, and
OE# control signals. Typical sleep mode current draw
from each device is < 1 µA. Standard address access
timings provide new data when addresses are
