CMOS LSI
LC6520C, 6522C, LC6520H, 6522H
Single-Chip 4-Bit Microcomputers for Medium/Large-Scale Control-Oriented Applications
The LC6520C/H are single-chip 4-bit microcomputers that contain a 4K-byte ROM, 1 K-bit RAM, have 42 pins, and are fabricated using CMOS process technology. Besides 8 input/output common ports of 32 pins and an input port of 4 pins, the LC6520C/H have specific ports that are used to provide the interrupt function, 4-bit/8-bit serial input/output function, and burst pulse output function. All output ports are of the open drain type with a withstand voltage of 15 V and a drive current of 20 mA and have the option of containing a pull-up resistance bitwise.
