Memory Connectors - PC Card Sockets (DS9094FS+)

Application Field

The DS9094FS+ is a model from a series of PC card sockets manufactured by Dallas Semiconductor. In the PC Card world the DS9094FS+ is a full-size card socket used to enable user access to PCMCIA and JEIDA compatible PC cards including SRAM, Flash, modem and digital communications cards.

This card socket is a relatively low-priced device designed for systems engineers to use and provide a fast, cost-effective connection standard for communication, storage and logging solutions. It is especially useful in the automotive and electronics industries, as its small size, high level of connectivity and wide range of features makes it ideal for use in limited space applications.

Working Principle

The DS9094FS+ PC card socket is essentially a pass-through device. It works by conveying the electronic signals from the connected PC card to the application device. As such, when a user inserts a PC card into the socket, the embedded electronic system recognises the card and transfers it’s information to the connected system.

The DS9094FS+ has a mateable contact points which bends slightly when a PC card is inserted. The force applied by these contact points creates an electrical connection between the card and the socket, allowing the electronic signals to pass through. The card is then identified and the device can access the card\'s data.

Features

The DS9094FS+ is capable of handling a wide range of PC cards, including both S2 and S3 versions, due to its built-in ‘Automatic Power Management’ feature. This allows the user to manually adjust the supply voltage by setting the card\'s contact points\' tension, depending on the voltage requirements of the respective card.

The DS9094FS+ is also suited to many applications, due to its wide operating temperature range and low power consumption. It has an operating temperature range of -40 to 85C and low power consumption of 8.8mA (min) and 12.5mA (max). In addition, the socket also provides EMC protection due to its noise cancelling circuit.

Conclusion

For those in the market for a compact card socket that can support a wide range of PC cards, the DS9094FS+ is a great option. It provides a fast and secure connection, with manual voltage adjustment for different cards, a wide temperature range and low power consumption. Overall, the DS9094FS+ is an excellent, cost-effective solution for adding a PC card output port to an existing device.
