In some engineering schools, the microcontroller is used in introductory microcontroller courses.


The following is a partial list of the ‘s registers, which are memory-mapped into the special function register space:. The MCS family was also discontinued by Intel, but is widely available in binary compatible and partly enhanced variants from many manufacturers.

All Silicon Labssome Dallas and a few Atmel devices have single cycle cores. The absolute memory address is formed by the high 5 bits of the PC and the 11 bits defined by the instruction. Retrieved datashet ” https: One feature of the core is the inclusion of a boolean processing engine which allows bit -level boolean logic operations to be carried out directly and efficiently on select internal registersports and select RAM locations.


More than 20 independent manufacturers produce MCS compatible processors. The irregular instructions dtasheet 64 opcodes, having more limited addressing modes, plus several opcodes scavenged from inapplicable modes in the regular instructions. The MCS has four distinct types of memory — internal RAM, special function registers, program memory, and external data memory.

JZ offset jump if zero. JC offset jump if carry set. Program fatasheet is read-only, though some variants of the use on-chip flash memory and provide a method of re-programming the memory in-system or in-application.

The original Intel ran at 12 clock cycles per machine cycle, and most instructions executed in one or two machine cycles. XRL Adata. CJNE Adata,offset. Where the least significant intdl of the opcode specifies one of the following addressing modes, the most significant specifies the operation:.

ORL addressA. Instructions that operate on single bits are:. Modern cores are faster than earlier packaged versions. Often used as ijtel general register for bit computations, or the “Boolean accumulator”. Carry bitC. RRC A rotate right through carry.


Intel MCS-51

Archived at the Wayback Machine. They were identical except for the non-volatile memory type. This section needs expansion. A vendor might sell an as an for any number of reasons, such as faulty code in the ‘s ROM, or simply an oversupply of s datsaheet undersupply of s.

Auxiliary carryAC. XRL addressA. Register select 0, RS0.

In Intel announced the MCS family, an up to 6 times faster variant, [3] that’s fully binary and instruction set compatible with Since data could be in one of three memory spaces, a mechanism is usually provided to allow determining to which memory a pointer refers, either by constraining the pointer type to include the memory space, or by storing metadata with the pointer.

You can help by adding to it. Most modern compatible microcontrollers include these features.
