CUnet slave IC, four 12-bit AD channels + DIO |
||
The MKY44-AD12A is a CUnet station (hearafter "slave") IC with analog input function. With an MKY44-AD12A, analog input and DIO control can be achieved on one chip without using the CPU. |
Measurement data according to the set mode is automatically input to the MKY44-AD12A's own memory block.
The input data is automatically copied to all CUnet ICs through CUnet communication (memory sharing), so the user CPU can acquire analog data easily just by reading the memory blocks corresponding to each slave IC.
Existing users of CUnet can get analog input just by adding this product to their networks.
New users have the opportunity to reduce A/D wiring that used to use parallel connections and to achieve easy, networked analog control.
