AMC0XXDFLKA Datasheet, PDF (43/46 Pages) Advanced Micro Devices – 4, 8, 20, or 32 Megabyte 5.0 Volt-only Flash Memory PC Card

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 V_CC is greater than V_LKO 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: V_CC = V_CCH,
V_PP =V_PPH, 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 V_CC and the GND pins. It is rec-
ommended the system side also have a 4.7 µF capac-
itor between the V_CC and the GND pins.
