“PC Card” is the name standardized by the “PC Cards
Standard”, a U.S.-Japan industry common standard that
was negotiated between PCMCIA(Personal Computer
Memory Card International Association) and
JEIDA(Japan Electronic Industry Development Associa-
tion).
In the beginning, PC cards were used as storage media
(memory cards) for personal computers, but because of
the need for additional functionality PC cards began to be
used as I/O devices in notebook PCs. Today, PC card
technologies have expanded to include Flash memory
cards which are used to transfer and store data from
ATA Flash cards
ATA flash cards use Flash memory as the memory
media and are a recognized PC Card standard by
PCMCIA/JEIDA. Because of the ATA format, a hard disk
interface for PC-AT type computers, ATA cards use
existing IDE/ESDI hard disk controller drivers allowing for
easy MS Windows compatibility and making them useful
for data transfer from items such as digital cameras.
Because the product does not have any mechanically
moving parts like a hard disk, it is highly resistant to
vibration or shock and provides high-speed access with
low power consumption.
SRAM cards
SRAM cards are re-writable and are best for applications
that need high read/write speed. SRAM cards contain
back-up batteries.
Characteristics of Panasonic PC Cards
Using our original MB(Multi-Layer Bonding)
methods to expand the memory size!
The MB method is our original technology which
uses the TAB system to bond the memory
chips to the film carrier and then stacks them
on the printed circuit board. MB technology
provides a mounting density 4 times that of
conventional SOP(*1) mounting and twice that
of TSOP(*2) mounting.
*1 SOP : Small Outline Package
*2 TSOP : Thin Small Outline Package
Realize smaller size, larger capacity PC cards with advanced technology.
(About PC
(Overview…)
items such as digital cameras, SCSI cards, Modem
cards, LAN cards, Audio cards and various combina-
tions of each.
PC cards also have expanded to include more func-
tionality in a smaller form for use with mobile devices.
Panasonic can satisfy the demands of next genera-
tion mobile devices with our large capacity, high
speed and high performance line-up of small PC
cards, memory cards and adapter
cards.
Flash memory cards
Flash memory cards contain linear flash memory and
have no need for any back-up batteries. Flash
memory can be deleted instantly and is re-writable so
these cards are best suited for applications that do
not need high read/write speeds and may require re-
write functionality.
PC Card Adapters
PC Card Adapters provide portable PC connectivity
for various small-sized removable storage media
cards by allowing them to be used in full-size PC
card (PCMCIA) slots.
