How many address lines and data lines are required for a 128k x 8 memory system?
17 address lines and 8 data lines. 2^17=128k
How many address lines and data lines are required from 256K 16 memory system?
In a 256K x 16 memory system, the memory has 256K (256 * 1024 = 262,144) addressable locations and each location holds 16 bits of data. To calculate the number of address lines needed, we find the base-2 logarithm of 256K, which is 18 (since 2^18 = 262,144). For the data lines, since each location holds 16 bits, 16 data lines are required. Thus, the system requires 18 address lines and 16 data lines.
How many data line does a 4 to 1 multiplexer have?
A 4 to 1 multiplexer has four data lines, typically labeled as D0, D1, D2, and D3. It uses two select lines to choose which of the four data inputs is routed to the output. Therefore, it can select one of four different data inputs based on the values of the select lines.
What chart uses parallel lines to show the data?
Number lines
What is the function of dptr?
The dptr (data pointer) is a register used in microcontroller architectures, particularly in the 8051 family, to point to data in memory. It facilitates access to data stored in external RAM or in the data memory space, allowing for efficient data manipulation and retrieval. By using dptr, programs can handle larger data sets and perform operations on data located beyond the internal memory limits.
How many address lines and data lines there in 8051?
12
How many instruction in 8051 microcontroller?
how many interrupts in 8051
What is the width of 8051 micro controller data bus?
The 8051 microcontroller has an 8-bit data bus width. This means it can transfer 8 bits of data simultaneously, allowing it to handle one byte of data at a time. The architecture is designed for efficient processing of 8-bit data, which is common in many embedded applications.
What is purpose of ram in 8051 micro controller?
the internal RAM is for data storage and for many applications is all that is needed.
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
How many data lines there in 8086?
There are 16 data lines in 8086.
Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
How many data input and data output lines does a RAM having capacity of 64K 16 need to have?
5 data input lines and 5 data output lines
How do you use on chip RAM of 8051?
In other words, how do you save temporary data such as data stored in registers r0 to r7 ? The simplest way to use on-chip RAM of the 8051 is to compile your C code with the "--model-small" small memory model option of the SDCC compiler, which tells it to put all variables in on-chip RAM of the 8051.
How many flags are there in 8051?
8
How many address lines and data lines are required for a2Kx8 memory?
A 2K X 8 memory requires 11 address lines and 8 data lines
Why 8051 is called 8 bit?
Because its a microcontroller with an 8 bit data bus width.
