The Intel 8051 microprocessor is a _________ processor.
8 bit
The Intel 8051 (MCS-51 family, 1980) is an 8-bit device: its ALU, accumulator (A), B register and internal data bus all handle 8-bit data, and its I/O ports are 8 bits wide.
It has 16-bit registers only for addressing (program counter and DPTR), giving 64 KB program and data memory space, but the word length of the processor is 8 bits. On-chip it also carries 4 KB ROM, 128 bytes RAM, four I/O ports, two 16-bit timers and a serial port, which is why it is usually called a microcontroller.
Intel’s 16-bit controller is the 8096, and 4-bit or 32-bit word lengths do not apply to the 8051.
Hence, the answer is 8 bit.
