VG-469, ISA-to-PC Card Controller
The VG-469 is a compact, highly integrated PC Card controller chip implementing the latest revisions to the PCMCIA/ JEIDA specifications alongwith ExCA™ extensions. It’s register set is a superset of the Intel®82365SL. Supporting two PC Card sockets, it is uniquely designed for space-limited, cost-sensitive applications where battery life is an important factor. For systems requiring more than two sockets, the VG-469 can be cascaded to support up to four sockets without external logic. With external decoder logic, unlimited cascading is possible. Typical VG-469 applications include small notebook computers, palmtops and other personal information devices, as well as docking stations for portable computers.
The VG-469 supports the system bus timing of standard ISA and EISA architectures, including those based on the Intel 386SL. A programmable configuration mechanism allows the system manufacturer to control many PC Card setup parameters in software or firmware. The VG-469 supports mixed voltage operation and is compliant with the new PCMCIA low voltage card interface specification. The ISA bus and each of the two PC Card sockets can be independently operated at either 3.3V or 5V.
Lead-Free version of VG-469 is available now. It is a Pin Compatible and Functional Equivalent to VG-469. It has the same silicon die as in VG-469. The only difference is the package material composition for the package used. Lead-content and other non-friendly environmental substances are completely removed from the package materials. Because of the material differences, solder reflow profile for VG-469-LF is slightly different from VG-469. The VG-469-LF is fully compliant to RoHS environmental standards.
