DESCRIPTION
The Fujitsu MB98A9083x, 9093x, 9103x and 9113x are Static Random Access Memory (SRAM) cards capable of storing and
retrieving large amounts of data. The memory circuits are housed in a credit-card sized 68-pin package. Internal circuitry is
protected by two metal panels, each one at the top and the bottom of the card, that help to reduce chip damage from electrostatic
discharge.
When the SRAM card is not powered by its system, an on-board, replaceable lithium battery (coin-type) is used to retain data.
When the lithium battery must be replaced, rechargeable battery that are built in the SRAM card, maintain data. (See the BLOCK
DIAGRAM for location of batteries.)
A unique feature of the Fujitsu memory cards allows the user to organize the card into either an 8-bit or a 16-bit bus configuration.
All cards are portable and operate on low power at high speed.
In accordance with the Personal Computer Memory Card International Association (PCMCIA) and Japan Electrical Industry
Development Association (JEIDA) industry standard specifications, SRAM cards offer additional EEPROM memory that is used
to store attribute data. The attribute memory is an SRAM card option. (See page 3 for a description of the three available options.)
Conformed to PCMCIA and JEIDA industry standards
Credit card size: 85.6 mm (length)
PCMCIA / JEIDA conformed two-piece 68-pin connector (with a two-row built-in 68-pin receptacle)
Low operating and standby power consumption
Built-in, rechargeable batteries for data retention during lithium battery replacement
Battery voltage detect and write protect function
54.0 mm (width)
3.3 mm (thick).
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions be taken to avoid application of any
voltage higher than maximum rated voltages to this high impedance circuit.
