What is the difference between 8051 and 8052 microcontrollers?
8052 is the super set of 8051 as it has all the features of 8051 with an extra timer and an extra RAM of 128 bytes. Therefore, 8052 has a total of 256 bytes of RAM and 3 timers in all. Also all the programs written for 8051 will run on 8052 as 8052 is super set of 8051, but it’s reverse is not true.
What is the ROM address range for 8052 chip?
Program Memory (ROM) of 8051 Microcontroller Almost all modern 8051 Microcontrollers, like 8052 Series, have 8KB of Internal Program Memory (ROM) in the form of Flash Memory (ROM) and provide the option of reprogramming the memory. In case of 4KB of Internal ROM, the address space is 0000H to 0FFFH.
What are the main components of a microcontroller?
A microcontroller can be seen as a small computer, and this is because of the essential components inside of it; the Central Processing Unit (CPU), the Random-Access Memory (RAM), the Flash Memory, the Serial Bus Interface, the Input/Output Ports (I/O Ports), and in many cases, the Electrical Erasable Programmable Read …
What are the specific on chip RAM sizes for microcontroller 8051 8052 and 8031?
8051 is the original name by Intel with 4 KB ROM and 128 byte RAM. Variants starting with 87 have a user programmable EPROM, sometimes UV erasable. Variants with a C as the third character are some kind of CMOS. 8031 and 8032 are ROM-less versions, with 128 and 256 bytes RAM.
What is the bit size of the 8052 microcontroller?
8052 is an 8-bit processor, meaning that the CPU can work on only 8 bits of data at a time. Data larger than 8 bits has to be broken into 8-bit pieces to be processed by the CPU. 8052 is available in different memory types such as UV-EPROM, Flash and NV-RAM.
What are the specific on-chip ROM sizes for microcontroller 8051 8052 and 8031?
It has 8K bytes of on chip program ROM. The programs written for projects using 8051 microcontroller can be used to run on the projects using 8052 microcontroller as 8051 is a subset of 8052. ii. 8031 – This microcontroller has all the features of 8051 except for it to be ROM-less.
