DESCRIPTION
The M66287FP is a high-speed field memory with three FIFO (First In First Out) memories of 262144-word x 8-bit configuration (2M bits) which uses high-performance silicon gate CMOS process technology. One of three FIFO memories consists of two FIFO memories of 262144-word x 4-bit (1M bits). Five types of operation can be performed through the following mode settings:

   Mode1 : 3-system delay data output by 3-system individual input of 256K-word x 8-bit FIFO
   Mode2 : Simultaneous output of 1 to 3-line delay data by 1-system input of 256K-word x 8-bit FIFO
   Mode3 : Simultaneous output of 1 to 2-line delay data by 1-system input of 256K-word x 8-bit FIFO
                 and,1-system delay data output by 1-system input of 256K-word x 8-bit FIFO
   Mode4 : 2-system delay data output by 2-system individual input of 256K-word x 12-bit FIFO
   Mode5 : Simultaneous output of 1 to 2-line delay data by 1-system input of 256K-word x 12-bit FIFO

The above-mentioned function is most suitable for image data correction across multiple fields. Because three pieces of 2M-bit FIFO are contained in one chip, a low power consumption of a set can be realized.
