The VIA VT83C469 is a highly integrated PC Card socket controller chip that implements the PCMCIA 2.0/JEIDA
4.1 specifications. The chip is register compatible with the INTEL 82365SL and supports two PC card sockets with a
fully buffered PCMCIA interface. No external buffer is required between the ISA bus and PCMCIA bus. For systems
requiring more than two sockets, the VT83C469 can be cascaded to support up to eight sockets without external
logic. Under EEPROM IO resource data, the VT83C469 can support unlimited sockets under ISA Plug and Play
mode
In addition, the VT83C469 offers a jumperless configuration mechanism which allows the system manufacturer to
set up a configuration (CONFIG.SYS) driver for PC card setup.
