VADEM VG-469
PC Card Socket Controller
Preface

PRODUCT OVERVIEW
The Vadem VG-469 is a compact, highly integrated PC Card controller chip implementing the
PC Card Standard along with ExCATM extensions. It is register-compatible to 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.
The VG-469 supports the system bus timing of standard ISA and EISA architectures. 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. The internal logic, the ISA bus interface and each
of the two PC Card sockets can be independently operated at either 3.3V or 5V.
Power management based on activity monitoring and the VG-469's very low current-draw
minimize the demand for battery power.
Jumperless add-in card installation is supported by the VG-469 with the on-chip implementation
of the Plug and Play ISA version 1.0a, which lets the software relocate the VG-469 registers from
the default at 3E0h/3E1h or 3E2h/3E3h.
PRODUCT FEATURES
·
208-pin chip provides full ExCA implementation of two PC Card sockets.
