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, costsensitive 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. Complies with PC Card Standard, and backward compatible to PCMCIA 2.1/JEIDA 4.1. Supports both memory cards and I/O cards. Supports PCMCIA-ATA specification. Memory-saving execute-in-place standard (XIP). Supports overlapping I/O windows across sockets and duplicate I/O cards via *INPACK signal. Cascadable up to four sockets without "glue," unlimited cascading with external logic. Register-compatible with Intel 82365SL. Five mappable memory windows and two I/O windows for each socket. Internal buffering supports `hot' insertion and removal of cards. Integrated timer supports power management based on activity monitoring.
