Overview

Ordering number: EN2076D No.
2076D 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.
The LC6520C/H are the same as our LC6500 series in the basic architecture of the CPU and the instruction set, but are made more powerful in the stack level and the cycle time.
The LC6522C/H are the same as the LC6520C/H, except that they contain a 2k-byte ROM, 512-bit RAM.
Features • Instruction set with 80 instructions {Common to the LC6500 series) • ROM/RAM : 4096 bytes/1024 bits (LC6520C/H) : 2048 bytes/512 bits < LC6522C/H) • Instruction cycle time: 6/is (C version, VQD = 3 to 5.
