The 8052 was an enhanced version of the original 8051 that featured 256 bytes of internal RAM instead of 128 bytes, 8 KB of ROM instead of 4 KB, and a third 16-bit timer. Most modern 8051-compatible microcontrollers include these features. The 8032 had these same features as the 8052 except it lacked internal ROM program memory.
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 .
FatFs is a lightweight software library for microcontrollers and embedded systems that implements FAT/exFAT file system support. [1] Written on pure ANSI C, FatFs is platform-independent and easy to port on many hardware platforms such as 8051, PIC, AVR, ARM, Z80.
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.
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 Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
The Low Voltage Series include the MSP430C09x and MSP430L092 parts, capable of running at 0.9 V. These 2 series of low voltage 16-bit microcontrollers have configurations with two 16-bit timers, an 8-bit analog-to-digital (A/D) converter, an 8-bit digital-to-analog (D/A) converter, and up to 11 I/O pins.
More recently, Semico has claimed the MCU market grew 36.5% in 2010 and 12% in 2011. [14] A typical home in a developed country is likely to have only four general-purpose microprocessors but around three dozen microcontrollers. A typical mid-range automobile has about 30 microcontrollers.
