PCMCIA Flash Memory Card
FLF Series
High Density FLASH Memory Card 16, 32, 48, 64, 80 MEGABYTE
General Description
Features
• Low cost, high density Linear Flash Card
WEDC’s Flash memory cards - FLF Series - offer
high density linear Flash memory for code and data
storage, high performance disk emulation, mobile PC
and embedded applications.
• Single 5V Supply
- (3V/5V operation is available as option)
• Based on Intel 28F640J5 (MLC) Components
The WEDC FLF series is based on Intel’s Multi Level
Cell (MLC) Flash memory technology, providing
high density Flash components at significantly lower
cost per megabyte. MLC technology allows for two
bits of information to be stored in a single cell. This
leads to reduced die size and reduced cost per
megabyte.
• Fast Read Performance
- 250ns Maximum Access Time
- (200ns optional)
•PCMCIA compatible
- x8/ x16 Data Interface
• 32-Byte Write Buffer
WEDC’s FLF series cards are built with Intel’s 64Mb
components, 28F640J5, with manufacturer/device ID
of 89/15H. The FLF series is available in standard
densities of 16, 32, 48 and 64MB.
- 6µs per Byte Effective Write Time
• Cross-Compatible Command Support
- Intel Basic Command Set
- Common Flash Interface (CFI)
- Scaleable Command Set
Additionally, WEDC’s FLF series provides densities
beyond the 64MB density, supported by PCMCIA
standard. These higher densities are based on a
“paging scheme”. By writing a page address to the
Configuration Option Register (address 4000H), an
additional page of memory could be access. The
current FLF series supports densities to 80MB: total
of 2 pages: page 0 := 64MB, page 1 := 16MB.
• Power-Down Mode
- Reset, Power Down Registers
• 10,000 Erase Cycles per Block
• 128K word symmetrical Block Architecture
• PC Card Standard Type II Form Factor
To provide a 16 bit word wide access and to support
PCMCIA standard, devices are paired on the card.
Therefore, the Flash array is structured in 128K word
(256kB) blocks. Write, read and block erase
operations can be performed as either a word or byte
wide operation.
