PCMCIA Flash Memory Card
FVF Series FVF Value Series Flash Memory Card General Description
The FVF Value Series Flash memory cards offer a low cost linear Flash solid state storage solution for code and data storage, high performance disk emulation, mobile PC and embedded applications. FVF series cards offer memory capacities from 4MB to 64MB, with 128kB block erase size. The WEDC Value series is based on Intel MLC, Strata Flash memories. Cards are based on the two families of memory components: FVF0x built with: 28F640J5, 28F320J5 FVF1x built with: 28F128J3, 28F640J3, 28F320J3 These flash devices support the Common Flash Interface (CFI) programming algorithm, a standard that allows system level software to evaluate the flash configuration, electrical characteristic, programming parameters and supported functions. CFI is intended to support future upgrades with universal programming algorithms, so there is no longer a need for continued programming software modification and updates. Systems should be able to recognize and support all devices to allow universal expansion/upgrade path. The symmetrically blocked architecture and single supply (5V for FVF0x and universal 3.3V or 5V for FVF1x cards) 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. The Value series is designed as a simple x16 linear array of Flash devices. One Flash device provides the lower and upper bytes for the 16 bit access. Other modes of operation are also supported (See Functional Truth Table on page 5) WEDC's standard Value Series Flash Card is shipped with no attribute memory or CIS (Card Information Structure) information. An option for 2KB of attribute memory with CIS information is available. The CIS for the WEDC Value series may also be stored in Block 0 (even bytes, D0 - D7 only) of the Flash memory. This option is available by request only. WEDC's standard cards are shipped with WEDC's Logo. Cards are also available with blank housings (no Logo). The blank housings are available in both a recessed (for label) and flat housing. Please contact WEDC sales representative for further information on Custom artwork.

4, 8, 16, 32, 48 and 64MB(Intel Strata Flash ) Features
· PCMCIA 2.1 (PC Card 97) compatible - Type I or Type II Form Factor · Low cost Linear Flash Card · Single Supply Operation · FVF0x - 5V · FVF1x - 5V or 3.3V (Note 1) · Fast Read Performance - 200ns Maximum Access Time · Based on MLC Strata Flash Components · Common Flash Interface (CFI) compliant · High Performance Random Writes - 6µs Typical per Byte Write Time, using 32Byte Write buffer · Automated Write and Erase Algorithms · High Write/Erase Endurance: 100,000 Write/Erase Cycles · Low Power Consumption · 150µA Standby Current · 75mA Max Byte Write Current
Note 1: FVF1x supports wide, universal operating voltage: 3V to 5V. That means the card will work in 3.3V systems as well as in 5V systems. This feature may allow easy exchange of data between multiple and different systems and provide easy upgrade / expansion path.

FVF Series
For information regarding modes of operation, commands, and programming details for the memory components, please consult the Intel 28F128J3A, 28F640J5 data sheets.
Writing commands to the CUI enables reading of device data, query, identifier codes, inspection and clearing of the status register, and, when VPEN = VPENH, block erasure, program, and lock-bit configuration. The Block Erase command requires appropriate command data and an address within the block to be erased. The Byte/Word Program command requires the command and address of the location to be written. Set Block Lock-Bit commands require the command and block within the device to be locked. The Clear Block Lock-Bits command requires the command and address within the device. The CUI does not occupy an addressable memory location. It is written when the device is enabled and WE# is active. The address and data needed to execute a command are latched on the rising edge of WE# or the first edge of CE1# or CE2# that disables the card. Standard microprocessor write timings are used.
