Description

Atmel's Flash Memory Card provides the highest system level
performance for data and file storage solutions to the portable
PC market segment. Data files and applications programs can be
stored on the AT5FC002. This allows OEM manufacturers of
portable system to eliminate the weight, power consumption and
reliability issues associated with electro-mechanical disk-based
systems. The AT5FC002 requires a single voltage power supply
for total system operation. No batteries are needed for data re-
tention due to its Flash-based technology. Since no high voltage
(12-volt) is required to perform any write operation, the
AT5FC002 is suitable for the emerging "mobile" personal sys-
tems.

The AT5FC002 is compatible with the 68-pin PCMCIA/JEIDA
international standard. Atmel's Flash Memory Cards can be
read in either a byte-wide or word-wide mode which allows for
flexible integration into various system platforms. It can be read
like any typical PCMCIA SRAM or ROM card.

The Card Information Structure (CIS) can be written by the
OEM or by Atmel at the attribute memory address space using a
format utility. The CIS appears at the beginning of the card's
attribute memory space and defines the low-level organization
of data on the PC card. The AT5FC002 contains a separate
2 Kbyte EEPROM memory for the card's attribute memory
space.

The third party software solutions such as AWARD Software's
CardWare

system and the SCM's Flash File System (FFS),

enables Atmel's Flash Memory Card to emulate the function of
essentially all the major brand personal computers that are
DOS/Windows compatible.

For some unique portable computers, such as the
HP200/100/95LX series, the software Driver and Formatter are
also available. The Atmel Driver and Formatter utilizes a self-
contained spare sector replacement algorithm, enabled by At-
mel's small 512-byte sectors, to achieve long term card
reliability and endurance.

*NOTICE: Stresses beyond those listed under "Absolute Maximum

Ratings" may cause permanent damage to the card. This is a stress
rating only and functional operation of the card at these or any
other conditions beyond those indicated in the
operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended pe-
riods may affect device reliability.

Notes:
1. Minimum DC voltage on input or I/O pins is -0.5 V. During volt-

age transients, inputs may overshoot V

to -2.0 V for periods of

up to 20 ns. Maximum DC voltage on output and I/O pins is
V

+0.5 V. During voltage transitions, outputs may overshoot to

+2.0 V for periods up to 20 ns.

2. No more than one output shorted at a time. Duration of the short cir-

cuit should not be greater than one second. Conditions equal

Address Inputs

Input

Address Inputs are internally latched during write cycles.

D0-D15

Data Input/Output

Input/Output

Data Input/Outputs are internally latched on write cycles. Data
outputs are latched during read cycles. Data pins are active high.
When the memory card is de-selected or the outputs are disabled
the outputs float to tri-state.

, CE

Card Enable

Input

Card Enable is active low. The memory card is de-selected and
power consumption is reduced to standby levels when CE is high.
CE activates the internal memory card circuitry that controls the
high and low byte control logic of the card, input buffers, segment
decoders, and associated memory devices.

Output Enable

Input

Output Enable is active low and enables the data buffers through
the card outputs during read cycles.

Write Enable

Input

Write Enable is active low and controls the write function to the
memory array. The target address is latched on the falling edge of
the WE pulse and the appropriate data is latched on the rising
edge of the pulse.
