Compact Flash to PC Card Adapter

Cactus has a Compact Flash to PC Card adapter for applications using a Compact Flash card in the larger sized PC Card form factor slots.

The CF to PC Card adapter converts the 50-pin Compact Flash interface to the 68-pin PC Card (previously known as PCMCIA) standard. Once a CompactFlash card is in the adapter, it meets the form, fit and function of a PC Memory Card.

This adapter is meant to be used with Cactus Technologies Compact Flash cards and can be used with a CompactFlash card in volume production systems if required.

Please contact Cactus if you need specific details regarding this adapter.

Compact Flash Extender Card for Development

To ease the access to the CompactFlash card signals during an OEM's design, Cactus created the CF Extender Card.

The CF Extender Card plugs into the standard CF slot and provides a slot for the CF card at the other end. On the PCB the signals are labeled so that they can be probed as necessary during development.

This is only meant for development of Cactus CF cards and is not available as a production product. Please contact Cactus if you need specific details regarding this adapter.
