MB98A9093x

Notes: *1. This value does not apply to the replaceable battery.
*2. This value does not apply to the replaceable battery and data retention.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

The Fujitsu MB98A9083x, 9093x, 9103x and 9113x are Static Random Access Memory (SRAM) cards capable of storing and retrieving large amounts of data. The MB98A9093x 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 MB98A9093x 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, MB98A9093x 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.)
