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 a pplications programs ca n be
stored on the AT5FC002. This allows OEM manufacturers of
portable system to eliminate the weight, power c onsumption and
reliability issues associated with electro-mechanical disk-based
systems. The AT5FC00 2 requires a single voltage power supply
for total system operation. No batteries a re needed for data retention due to its Flash-based technology. S ince no high voltage
(12-volt) is required to perform any write operation, the
AT5FC002 is suitable for the emerging "mobile" personal systems.
The AT5FC002 is com pa tible wi th the 68-pin P CMC IA/JEI D A
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 pla tforms. It can be rea d
like any typical PCMCIA SRAM or ROM card.
Block Diagram
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 sol ut ion s such as AWARD Softw are’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 selfcontained spare sector replacement algorithm, enabled by Atmel’s small 512-byte sectors, to achieve long term card
reliability and endurance.

Memory Card Operations
The AT5FC002 Flash Memory Card is organized as an array of
4 individual AT29C040A devices. They are logically define d as
contiguous sectors of 512 bytes. Each sector can be read and
written randomly as designated by the host. Th ere is N O need to
erase any sector prior to any write operation. Also, there is NO
high voltage (12 V) required to perform any write operations.
The common memory space data contents are altered in a similar manner as writing to individual Flash memory devices. Oncard address and data buffers activate the appropriate Flash device in the memory array. E ach devic e internally latche s addres s
and data during wri te cycles. Refer to the Common M emoryOperations table.
Byte-Wide Operations
The AT5FC002 provides the flexibility to operate on data in
byte-wide or word-wide oper ations . Byte- wid e dat a is a va ilable
on D0-D7 for read and write operations (
high). Even and odd bytes are stored in a pair of memory chip
segments (i.e., S0 and S1) and are accessed when A0 is low and
high respectively.
Word-Wide Operat io n s
The 16-bit words are accessed when both CE1 and CE2 are
forced low, A0 = don’t care. D0-D15 are used for word-wide
operations
Read Enable/Output Disable
Data outputs from the card are disabled when OE is at a logichigh level. Under this condition, outputs are in the high-impedance state. The A20 selects the paired memory chip segments,
while A0 decides the upper or lower bank. The
determine either byte or word mode operation. The Output Enable (
OE) is forced low to activate all outputs of the memory
chip segments. The on-card I/O transceiver is set in the output
mode. The AT5FC002 sends data to the host. Refer to A.C.
Read Waveforms drawing.
Standby Operations
When both CE1 and CE2 are at logic-high level, the AT5FC002
is in Standby mode; i.e., all memory chip segme nts as well as the
decoder/transceiver are completely de-selected at minimum
power consumption. Even in the byte-mode read operation, only
one memory chip segment (even or odd) is active at any time.
The other seven memory chip segments remain in standby. In
the word-mode there are two memory chip segments in active
and six in standby.
Write Operations
The AT5FC002 is written on a sector basis. Each sector of 512
bytes can be selected randomly and written indepe ndently without any prior erase cycle. A9 to A19 specify the sector address,
while A20 specifies the Flash chip segment pair. Within each
sector, the individual byte address is latched on the falling edge
of
CE or WE, whichever occurs last. The data is latched by the
CE1 = low, CE2 =
CE1/CE2 pins

must have its high-to-low transition on
µs of the low-to- high transition of
byte pair. If a high-to-low transition is not detected within 150
µs of the last low-to-high transition, the data load period will
end and the internal programming period will start. All the bytes
of a sector are simultaneously programmed during the internal
programming period. A maximum write time of 10 ms per sector is self-controlled by the Flash devices. Refer to A.C. Write
Waveforms drawings.

Write Protection
The AT5FC002 has five types of write protection. The
PCMCIA/JEIDA socket itself provides the first type of write
protection. Power supply and control pins have specific pin
lengths in order to protect the card with proper power supply
sequencing in the case of hot insertion and removal.
A mechanical write protection switch provide s a second type of
write protection. When this swit ch is ac tivated,
forced high. The Flash memory arrays are therefore write-disabled.
The third type of write protection is achieved with the built-in
low VCC sensing circuit within each Flash device. If the external VCC is below 3.8 V (typica l), the write f unction is inhibited.
The fourth type of write protection is a noise filter circuit within
each Flash device. Any pulse of less than 15 ns (typical) on the
WE, CE1 or CE2 inputs will not initiate a program cycle.
The last type of write protection is based on the Software Data
Protection (SDP) scheme of the AT29C040A devices. Each of
the sixteen devices needs to enable and disable the SDP individually. Refer to the Software Data Protected Program-ming/Disable Algorithm tables for descriptions of enable and
disable SDP operations.

Card Detection
Each CD (output) pin should be read by the host system to determine if the memory ca rd is properly sea ted in the socket.
and CD2 are internally tied to the ground. If both bits are not
detected, the system should indicate that the card must be
re-inserted.
CD
CIS Data
The Card Information Structure (CIS) describes the capabilities
and specifications o f a card. T he CIS of the AT5FC002 can be
written either by the OEM or by Atmel at the attribute memory
space beginning at address 00000H by using a format utility.
The AT5FC002 contains a separate 2 Kbyte EEPROM memory
for the card’s attribute memory space. The attribute is active
when the
tribute memory access. D8-D15 should be ignored. Odd order
bytes present invalid data. Refer to the Attribute MemoryOperations table.
