The Intel MCS-51 (commonly termed 8051) is a single-chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton .
SAB-C515-LN by Infineon is based on the 8051. The Infineon XC800 family is an 8-bit microcontroller family, first introduced in 2005, [1] with a dual cycle optimized 8051 "E-Warp" [2] [3] core. The XC800 family is divided into two categories, the A-Family for Automotive and the I-Family for Industrial and multi-market applications.
A microcontroller can be considered a self-contained system with a processor, memory and peripherals and can be used as an embedded system. [27] The majority of microcontrollers in use today are embedded in other machinery, such as automobiles, telephones, appliances, and peripherals for computer systems.
Texas Instruments TMS320 C55x processors, for one example, feature multiple parallel data buses (two write, three read) and one instruction bus. Microcontrollers are characterized by having small amounts of program (flash memory) and data ( SRAM ) memory, and take advantage of the Harvard architecture to speed processing by concurrent ...
Manufactures a line of 8-bit 8051-compatible microcontrollers, notable for high speeds (50–100 MIPS) and large memories in relatively small package sizes. A free IDE is available that supports the USB-connected ToolStick line of modular prototyping boards. These microcontrollers were originally developed by Cygnal.
Today a Harvard machine such as the PIC microcontroller might use 12-bit wide flash memory for instructions, and 8-bit wide SRAM for data. In contrast, a von Neumann microcontroller such as an ARM7TDMI, or a modified Harvard ARM9 core, necessarily provides uniform access to flash memory and SRAM (as 8 bit bytes, in those cases).
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
Various older (EPROM) PIC microcontrollers. The original PIC was intended to be used with General Instrument's new CP1600 16-bit central processing unit (CPU). In order to fit 16-bit data and address buses into a then-standard 40-pin dual inline package (DIP) chip, the two buses shared the same set of 16 connection pins.
