LU800V1

The LU800V1 is designed as one kind of CMOS 8 bit single chip microcomputers(ROM less),and it is a version of the SM803/A and SM805/A CMOS 8-bit single-chip microcomputers and offers the outsyanding features of the Z8 family architecture.Because some I/O ports are used for address/data bus,this device accesses up to 128K bytes of the external memory space.Using the external memory in place of an on-chip ROM allows designing more powerful microcomputer system.

Features of the LU800V1 are:(1)complete microcomputer,24 I/O lines and up to 64K bytes addressable external space each for program and data memory;(2)143 bytes register file,124 general-purpose registers and 3 I/O port registers;(3)register pointer so that short,fast instructions can access any one of the 9 working-register groups;(4)full-duplex UART and two programmable 8-bit counter/timers,each with a 6/bit programmable prescaler;(5)vectored priority interrupt for I/O,counter/timers and UART;(6)on-chip oscillation circuit;(7)single +5V power supply.

The LU800V1 has a dedicated memory interface port and input/output ports.These ports are given eight lines each.The functions of port 0,2 and 3 are the same as those of the SM803/A,SM805/A.If you want to know more information about this LU800V1,please download the datasheet in www.seekic.com and www.seekdatasheet.com
