Program memory is read-only, though some variants of the 8051 use on-chip flash memory and provide a method of re-programming the memory in-system or in-application. In addition to code, it is possible to store read-only data such as lookup tables in program memory, retrieved by the MOVC A , @ A + DPTR or MOVC A , @ A + PC instructions.
MCU 8051 IDE has a built-in simulator not only for the MCU itself, but also LCD displays and simple LED outputs as well as button inputs. It supports two programming languages: C (using SDCC ) and assembly and runs on both Windows and Unix -based operating systems, such as FreeBSD and Linux .
The Small Device C Compiler (SDCC) is a free-software, partially retargetable [1] C compiler for 8-bit microcontrollers. It is distributed under the GNU General Public License. The package also contains an assembler, linker, simulator and debugger. SDCC is a popular open-source C compiler for microcontrollers compatible with Intel 8051/MCS-51 ...
Keil is a German software subsidiary of Arm Holdings.It was founded in 1982 by Günter and Reinhard Keil, initially as a German GbR.In April 1985 the company was converted to Keil Elektronik GmbH to market add-on products for the development tools provided by many of the silicon vendors.
MPLAB X supports editing, very buggy debugging and programming of Microchip 8-bit, 16-bit and 32-bit PIC microcontrollers. MPLAB X is the first version of the IDE to include cross-platform support for macOS and Linux operating systems, in addition to Microsoft Windows. MPLAB X supports the following compilers:
An AT89c2051 microcontroller in circuit. The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (μCs) manufactured by the Atmel Corporation.. Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL (DIP ...
For example, the program counter is not directly writeable in many microcontroller architectures. Instead, the programmer uses instructions such as return from subroutine, jump, or branch to modify the program counter. For another example, the condition code register might not be directly writable, instead being updated only by compare ...
The DS80C390 is a microcontroller, introduced by Dallas Semiconductor (later part of Maxim Integrated Products, now part of Analog Devices), whose architecture is derived from that of the Intel MCS-51 (aka. 8051) processor series. It contains a code memory address space of twenty-two bits.
