OUTLINE
The RF5C296, the RF5C396L, the RB5C396, and the RF5C396 are enhanced version of the RF5C266 and RF5C366, LSIs functioning as controllers for interfacing IC memory cards, modems, and I/O cards, such as HDDs, to system buses in compliance with the PCMCIA2.1 or JEIDA4.2 Standard. These controller LSIs can be used to configure an ISA bus system which supports PC cards. The RF5C296 supports one PC card slot while the RF5C396L, the RB5C396 and the RF5C396 support two PC card slots. Incorporating a buffer and a transceiver, each of these devices can be directly coupled to the ISA system bus and the PC card slots. The devices are also capable of providing an independent power supply of 3.3V or 5V for each slot interface, system bus, and core logic. Further, they effect substantial space savings through implementation in slimline packages (i.e. the 144pin LQFP for the RF5C296, the 208pin LQFP for the RF5C396L, the 256pin PBGA for the RB5C396 and the 208pin QFP for the RF5C396). Unless otherwise noted, the RF5C396L, the RB5C396 and the RF5C396 are collectively referred to as the RF5C396 in this manual.
