PCMCIA Flash Memory Card
FEB Series
Eight Bit Flash Memory Card (AMD based) 1, 2, and 4 MEGABYTE
General Description
Features
• Low cost Linear Flash Card
The FEB Econo Flash card series offers a low cost eight
bit linear Flash solid state storage solution for code/data
storage and embedded applications.
• Single 5 Volt Supply
•Based on AMD Flash Components
Packaged in PCMCIA type I or a type I half-card housing,
the FEB card series is based on AMD Flash memories:
Am29F080 (8Mb) or Am29F016 (16Mb) devices whose
device codes are D5h and ADh respectively. Systems
should be able to recognize both codes. The
symmetrically blocked architecture and 5V operation
provides a cost effective, high performance, nonvolatile
storage solution. The PC Card form factor offers an
industry standard pinout and mechanical outline, allowing
density upgrades without system design changes.
- very low power without entering reset mode
- allows standard access from low power mode
•Fast Read Performance
- 100ns or 150ns Maximum Access Time
• x8 Data Interface
• High Performance Random Writes
- 10µs Typical Word Write Time
• Automated Write and Erase Algorithms
- AMD Command Set
The FEB card series is designed as a simple x8 linear
array of Flash devices. The 2MB and 4MB density options
may be built with either 8Mb or 16Mb components. Both
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 AMD based
components allow for very low standby currents without
entering Reset mode. This allows for standard access time
immediately from low power standby mode.
• 50µA Typical Deep Power-Down
• 100,000 Erase Cycles per Block
• 64K word symmetrical Block Architecture
• PC Card Standard Type I Form Factor
