CARD INFORMATION STRUCTURE

The D-Series card contains a separate EEPROM

memory for the Card Information Structure (CIS).

This allows all of the Flash memory to be used for the

common memory space. Part of the common memory

space could also be used to sore the CIS.

The EEPROM used in the D-Series card is designed

to operate from a 5 V single power supply. Table 9

shows the CIS information stored in the AMD Flash

memory card.

SYSTEM DESIGN AND INTERFACE

INFORMATION

Power Up and Power Down Protection

AMD’s Flash memory devices are designed to protect

against accidental programming or erasure caused by

spurious system signals that might exist during power

transitions. The AMD PC Card will power-up into a

READ mode when VCC is greater than VLKO of 3.2 V.

Erasing of memory sectors or memory segments can

be accomplished only by writing the proper Erase com-

mand to the card along with the proper Chip Enable,

Output Enable and Write Enable control signals. Hot in-

sertion of PC cards is not permitted by the PCMCIA

standard.

Note: Hot insertion is deﬁned as the socket condition

where the card is inserted or removed with any or

all of the following conditions present: VCC = VCCH,

VPP =VPPH, address and/or data lines are active.

System Power Supply Decoupling

The AMD Flash memory card has a 0.1

µF decoupling

capacitor between the VCC and the GND pins. It is rec-

ommended the system side also have a 4.7

µF capac-

itor between the VCC and the GND pins.
