why the microcontroller so called 8051?/ and why the IC starts with 74?..

Answer / balasairam.k

it is 8-8 bit processor 8000series
5-it has five interrupts
1 -serial port
so it is called as 8051

Answer / balasubramanian

8051
8-8bit controller(Data BUS)
0-Romless device(except 8051,8052 has internal ROM) but 8031 other are dont have Internal ROM
5-5 interrupts(INT0,TF0,INT1,TF1,TI+RI)
1-Serial Communication(8-bit UART)

Answer / suraj thakur

8051 called 8051 because
8- 8 bit processor
5- 5 intreupt
1- serial port

and 74 series called 74 because
1= 7 pin low
2= 4 gate consist in each ic
like in 7400 consist 4 NAND gate

Answer / shyam sundor ghosh

8 mean-8 bit processor 8000series
5 mean-it has five interrupts
1 mean -serial port
so it is called as 8051

IC starts with 74 because we give activation voltage of the
IC at 7 & 4 no. pin of the IC.
