CL-PS6700-VC-A中文资料凌云逻辑数据手册PDF规格书

OVERVIEW

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]).
