PCMCIA Flash Memory Card
FVA Series Value Series Flash Memory Card General Description
The WEDC Value Series (FV) Flash memory cards offers a low cost linear Flash solid state storage solution for code and data storage, high performance disk emulation, mobile PC and embedded applications. The WEDC Value series is based on Intel/Sharp Flash memories. Cards are based on the 28F008SA (8Mb), 28F008S5 (8Mb) or 28F016S5 (16Mb) devices whose device codes are A2H, A6H and AAH respectively. Systems should be able to recognize all three codes. The symmetrically blocked architecture and single 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. The Value series is designed as a simple x16 linear array of Flash devices. Two Flash devices in parallel provide the lower and upper bytes for the 16 bit access. The Value series does not provide access of the ODD byte (D8 - D15) on the even byte data path (D0 - D7). 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.

FVA Series Card Signal Description
Symbol A0 - A25 Type INPUT Name and Function ADDRESS INPUTS: A0 through A25 enable direct addressing of up to 64MB of memory on the card. Signal A0 is not decoded since the card is x16 only. The memory will wrap at the card density boundary. The system should not try to access memory beyond the card density. The upper addresses are not connected. DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the bi-directional databus. DQ0 - DQ7 constitute the lower (even) byte and DQ8 - DQ15 the upper (odd) byte. DQ15 is the MSB. CARD ENABLE 1 AND 2: CE1# enables even byte accesses, CE2# enables odd byte accesses. Odd byte (DQ8 - DQ15) can not be accessed on DQ0 - DQ7. OUTPUT ENABLE: Active low signal enabling read data from the memory card. WRITE ENABLE: Active low signal gating write data to the memory card. READY/BUSY OUTPUT: Indicates status of internally timed erase or program algorithms. A high output indicates that the card is ready to accept accesses. CARD DETECT 1 and 2: Provide card insertion detection. These signals are connected to ground internally on the memory card. The host socket interface circuitry shall supply 10K-ohm or larger pull-up resistors on these signal pins. WRITE PROTECT: This signal is pulled low internally. This signifies write protect = "off " for all cases. PROGRAM/ERASE POWER SUPPLY: Not connected for 5V only card. CARD POWER SUPPLY: 5.0V for all internal circuitry. GROUND: for all internal circuitry. ATTRIBUTE MEMORY SELECT : only used with cards built with optional attribute memory. RESET: Active high signal for placing card in Power-on default state. Reset can be used as a Power-Down signal for the memory array. WAIT: This signal is pulled high internally for compatibility. No wait states are generated. BATTERY VOLTAGE DETECT: These signals are pulled high to maintain SRAM card compatibility. VOLTAGE SENSE: Notifies the host socket of the card's VCC requirements. VS1 and VS2 are open to indicate a 5V, 16 bit card has been inserted. RESERVED FOR FUTURE USE NO INTERNAL CONNECTION TO CARD: pin may be driven or left floating
