8051 is an old microcontroller design. It has been updated and expanded into a family of microcontrollers manufactured by several companies.
PIC is not a microcontroller, but is an extensive family of microcontrollers designed and manufactured by Microchip, Inc.
Both are quite popular, and there are many other microcontrollers available.
89c51 microcontroller is of the series of 8051,one of oldest yet commonly used microcontroller.89c51 have the less complex features then other microcontroller and it is also easily available and cheap in comparison of other microcontrollers.
OTP 8051 refers to a specific type of microcontroller based on the 8051 architecture, which is programmed using One-Time Programmable (OTP) memory. This means that once the program is written to the chip, it cannot be modified or erased, making it ideal for applications where the code is finalized and will not need updates. OTP 8051 microcontrollers are commonly used in embedded systems for tasks like control, automation, and data processing. Their limited reusability is compensated by their reliability and simplicity in design.
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.
In the context of the 8051 microcontroller, Tmp 1 and Tmp 2 refer to temporary registers or memory locations used during the execution of instructions. These temporary registers are often utilized by the CPU to hold intermediate data or results during arithmetic and logical operations. They help optimize processing by reducing the need to access slower main memory frequently. However, specific naming conventions like Tmp 1 and Tmp 2 may vary, as the 8051 architecture mainly utilizes general-purpose registers for such temporary storage.
AT89S52 is a microcontroller based on the Intel 8051 architecture and features. Concerning your question, AT89S52 is the heart of most project involving Dual Tone Multi Frequency (DTMF), that is to say it is the controller IC used in such project.
An 8051 microcontroller is a popular 8-bit microcontroller that was first introduced by Intel in 1980. It is widely used in embedded systems due to its simple architecture, low cost, and ease of use. The 8051 microcontroller typically includes CPU, RAM, ROM, I/O ports, timers, and serial communication interfaces on a single chip.
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
8051 Microcontrollers were popular computer chips used in Intel computers throughout the eighties and nineties. Though technology has advanced beyond their common use, they can still often be found in engineering schools as tools used in introductory microcontroller classes.
89c51 microcontroller is of the series of 8051,one of oldest yet commonly used microcontroller.89c51 have the less complex features then other microcontroller and it is also easily available and cheap in comparison of other microcontrollers.
The 8051 can directly interface with a number of I/O. The 8255 just gives you the abilty to access 3 eight bit ports using a minimum number of control bits from the 8051
The output of 8051 micro controller is active high so we must need to use the common cathode type display . it will work glow when any input is high . The anode terminals of leds's of seven segment connected to 8051's output and cathode is common and grounded . so it require common cathode because 8051 provide active high output.
