Description

The CL-PS6700 connects directly to a PC Card (PCMCIA) Release 2.01 socket and has a custom interface to the CL-PS7111 microcontroller. The CL-PS7111 can support up to two CL-PS6700 devices, which allows up to two PC Card sockets per system. Addresses and data are passed to the CL-PS6700 through 16 bits of the 32-bit Data bus (D[15:0]).

The PC Card socket is effectively isolated by the CL-PS6700. Except for power and ground pins, the pins on the socket only connect to the rest of the system through the CL-PS6700.
