Detailed explanation-1: -Explanation: If we say a microcontroller is 8-bit it means that it is capable of processing 8-bit data at a time. Data processing is the task of ALU and if ALU is able to process 8-bit data then the data bus should be 8-bit wide.
Detailed explanation-2: -8051 has many instructions and functions like 8-bit ALU, timers, and counters which are 16-bit each, the on-chip ram of 128 0r 256 bytes, has an 8-bit data bus, 32-bit address bus, and holds ROM memory size 64kb each.
Detailed explanation-3: -8-bit microcontroller − this type of microcontroller is used to execute arithmetic and logical operations like addition, subtraction, multiplication division, etc. For example, Intel 8031 and 8051 are 8 bits microcontroller.
