PCMCIA Flash Memory Card
FEA Series
Eight Bit Flash Memory Card (Intel based) 512KB, 1, 2, 4 and 8 MEGABYTE
General Description
Features
• Low cost Linear Flash Card
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.
• Single 5 Volt Supply (S5 devices)
or 5V Vcc / 12V Vpp (SA devices)
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.
• Based on Intel/Sharp Flash Components
- very low power in Sleep Mode
• Fast Read Performance
- 100ns or 150ns Maximum Access Time
• x8 Data Interface
• High Performance Random Writes
- 10µs Typical Byte Write Time
• Automated Write and Erase Algorithms
- Intel Command Set
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
• 50µA Typical Power-Down
• 100,000 Erase Cycles per Block
• 64K word symmetrical Block Architecture
• PC Card Standard Type I Form Factor
16Mb components.
All components have uniform
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.
