The families differ mostly in instruction sets and architecture. The Intel microcontroller, Intel’s first µC, was used in the Magnavox Odyssey² video game. The first controllers to gain really widespread use were the Intel , which was integrated into PC microcontroller is a processor with memory and a whole lot of other ..

The high-performance register to register architecture is well suited for complex real-time control applications such as hard disk drives, modems, printers, pattern recognition and motor control.
The families differ mostly in instruction sets and architecture. Ramadan Al-Azhar University Lecture 3. D C circuit diagram of antilog circuit log amplifier diode LA LA using bc transistor Text: It contains the operands or one of the operands of arithmetic or logical instruction and holds the result of that instruction.
The instruction set is based on that of the The standard MCS instruction set has instructions with 64 of them executing in a single cycle. EPA Famlily Event processor array.

Micrcontroller was still manufactured into the s to support older designs that still used it. Below is a general overview of each type of Intel Microcontroller Family. This allows bit addresses to be used. The Archutecture In this module, we will be discussing the MCS family of microcontroller, in particular thewhich is the generic IC representative. The Microprocessor Theannounced inwas the first bit microprocessor introduced by Intel Corporation is bit MPU.
The external memory must start at memory location H and can be up to a full 64kbytes.
Intel MCS – Wikipedia
The accumulator is byte- or bit-addressable. The first 32 memory locations can be used as four register banks. The B register is used during multiply and divide operations as one 8-bit source and to hold the high-order 8 bits.
Because these single-byte instructions have only 3 bits available to address the register, they address only one of eight registers. The processor can read data from this memory space and can write data to this memory space.
Views Read Edit View history.
It was inspired by, and is somewhat similar to, the Fairchild F8 microprocessor. Its first members wereand While each CPU may have the same core micrpcontroller feature set can vary a lot.
From Wikipedia, the free encyclopedia. The first Intel 8-bit microcontroller was the The program memory space is a read-only space.
All output stages are open collectors each capable of sinking mA to drive.
Share buttons are a little bit lower. This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1. Other special instructions can address any individual bit in these memory locations. Common differences within a single family are: Logic 1 selects register S1, logic 0 selects one of the other registers.
Although addressable as memory locations, these registers must be used for their intended purpose. Part of this memory space is often referred to as general purpose registers. It cannot execute program instructions from this memory space.
