2412A LC6568D, CMOS LSI 6568H 8K-Byte ROM-Contained Single-Chip 4-Bit Microcomputers with FLT/LED Drivers, Comparator Input The L C 6 5 6 8 D / H are single-chip 4-bit microcomputers that contain an 8K-byte ROM, 1 K-bit RAM, and have 64 pins.
The LC6568D/H have 57 pins for ports — 28 pins for 7 input/output common ports, 21 pins for 6 output ports, and 8 pins for 2 input ports.
The L C 6 5 6 8 D / 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.
Each of the 28 pins for input/output common ports contains a driver with a withstand voltage of 15V max.
and a drive current of 15mA max.
and each of the 21 pins for output ports contains a high-voltage output driver of the P-channel open drain type.
Since the high-voltage output driver can be used as general-purpose high-current driver as w e l l as fluorescent tube driver, the L C 6 5 6 8 D / H can be also w i d e l y used in applications where no fluorescent display is provided.
T h e L C 6 5 6 8 D / H are t h e same as o u r L C 6 5 0 0 series in t h e basic architecture of the CPU and the i n s t r u c t i o n set, b u t are made more powerful in the stack level and also made easier-to-use in the standby function.
Features • Instruction set w i t h 81 instructions (Common to the LC6500 series) • On-chip 8192-byte ROM, 1024-bit RAM • I n s t r u c t i o n cycle t i m e : 2 .
