H Datasheet(PDF) – Intel Corporation

It is a large and heavy desktop box, about a 20″ cube in the Intel corporate blue color which includes a CPU, monitor, and a single 8-inch floppy disk drive. Retrieved from ” https: Trainer kits composed of a printed circuit board,and supporting hardware are offered by various companies.

Only a single 5 volt power supply is needed, like competing processors daasheet unlike the When untel wish to use port A or port B for handshake strobed input or output operation, we initialise that port in mode 1 port A and port B can be initilalised to operate in different modes, i.

These are intended to be supplied by external hardware in order to invoke a corresponding interrupt-service routine, but are also often employed as fast system calls.

Intel softw are products are cop yrighted by and shall rem ain the property ontel f Intel C orp ora tion. This means that data can be input or output on the same eight lines PA0 – PA7.

Figure 3 shows the timing. The sign flag is set if the result has a negative sign i.

Some of them eatasheet followed by one or two bytes of data, which can be an immediate operand, a memory address, or a port number. When the Intel bus. Intel is com m itted to the technology o f electrically erasable PROMs and we. Intel C orp ora tion makes no w arranty fo r the datssheet o f its products and assumes no re sponsib ility foinfo rm atio n contained herein.

The following list provides some of the key features on this processor: Previous 1 2 In many engineering inel [7] [8] the processor is datazheet in introductory microprocessor courses. However, an circuit requires an 8-bit address latch, so Intel manufactured several support chips with an address latch built in.


A downside compared to similar contemporary designs such as the Z80 dahasheet the fact that the buses require demultiplexing; however, address latches in the Intel, and memory chips allow a direct interface, so an along with these chips is almost a complete system. The incorporates the functions of the clock generator and the system controller on chip, increasing the level of integration. Since use of these instructions usually relates to specific hardware features, the necessary program modification would typically be nontrivial.

Try Findchips PRO for intel pin diagram. All data, control, and address signals are available on dual pin headers, and a large prototyping area is provided. The CPU is one part of a family of chips developed by Intel, for building a complete system.

The has extensions to support new interrupts, untel three maskable vectored interrupts RST 7. A number of undocumented instructions and flags were discovered by two software engineers, Wolfgang Dehnhardt and Villy M. The two modes are selected on the basis of the value present at the D 7 bit of the control word register.

All of these chips were originally available in a pin DIL package. Direct copying is supported between any two 8-bit registers and between any 8-bit register and a HL-addressed memory cell, using the MOV instruction. These instructions are written in the form of a 88155 which is used to perform various operations such as branching, addition, subtraction, bitwise datzsheetand bit shift operations. Views Read Edit View history. It can also accept a second processor, allowing a limited form of multi-processor operation where both processors run simultaneously and independently.

Intel 8085

Pin 39 is used as the Hold pin. As in many other 8-bit processors, all instructions are encoded in a single byte including register-numbers, but excluding immediate datafor simplicity. This was typically longer than the product life of desktop computers. Each line of port C PC 7 – PC 0 can be set or reset by writing a suitable value to the control word register. This mode is selected when D 7 bit of the Control Word Register is 1.


The ports provide the latching of data andE2PROM possesses Intel ‘s 2-line control architecture to eliminate bus contention in a systemwith such simple control.

For example, multiplication is implemented using a multiplication algorithm. These kits usually include complete documentation allowing a student to go from soldering to assembly language programming in a single course. This unit uses the Multibus card cage which was intended just for the development system. A NOP “no operation” instruction exists, dwtasheet does not modify any of the registers or flags.

The other six registers can be used as independent byte-registers or as three bit register pairs, BC, DE, and HL or B, D, H, as referred to in Intel documentsdepending on the particular instruction.

Also, the architecture and instruction set of the are easy for a student to understand.

The uses Intel ‘s proven 2-line control architecture for read operation. The parity flag is set according to the parity odd or even of the accumulator.
