PCMCIA Flash Memory Card
FEA Series
Eight Bit Flash Memory Card (Intel based)
General Description
The FEA Econo Flash card series offers a low cost and
high performance eight bit linear Flash solid state storage
solution for code/data storage and embedded applications.
Packaged in PCMCIA type I or a type I half-card housing,
the FEA card series is based on Intel/Sharp Flash memory
devices: 28F0004S5 (4Mb), 28F0008S5 (8Mb) or
28F016S5 (16Mb) for
5V
only applications and
28F008SA (8Mb) for 5V/12V applications. Device codes
are A7h, A6h, AAh, and A2h respectively. Systems
should be able to recognize all codes. The PC Card form
factor offers an industry standard pinout and mechanical
outline, allowing density upgrades without system design
changes.
The FEA card series is designed as a simple x8 linear
array of Flash devices. The 512KB density cards are built
with 4 Mb components (5V only), 2MB and 4MB density
options may be built with either 8Mb or 16Mb
components, and the 8MB density cards are built with
16Mb components.
All components have uniform
• PC Card Standard Type I Form Factor
64Kbyte sectors and use identical embedded automated
write and erase algorithms. The 8 bit design provides very
low power operation as only one component is active at a
time.
The Intel Flash components provide very low
standby current in Sleep Mode.
