Why memory capacity of 8085 mp is 64 KB?
The memory capacity of the 8085 microprocessor is 64 kb because the address bus is 16 bits, and you can address 216, or 64kb, with a 16 bit address bus.
Block diagram of ic-7489 as 16x4 ram?
Use the link below to go to the data sheet for the IC. On page 5-4 you will see the logic diagram. Using it you can see that A0 - A3 are the address lines used to select the memory location to read from or write to. There are 16 locations. These work in conjunction with the 4 input AND IC's 1-16. These are the decoder section to decode the address and select the memory row. Pin 2 is the Memory Enable pin. This pin enables the memory when it is held low. At the bottom of the page you see the 4 data inputs D1-D4. These are used to input data into memory when the Write Enable Pin (Pin 3) is held low. When the Write enable pin is held high, the data stored at the memory location selected by the address lines will be placed on the outputs. However, the outputs are complemented. So if the data at the selected address is 1001, the output will be 0110. Thus to see the actual data, you would need an inverter on the outputs. So you basically have the address decoder, the memory cells, and the I/O control if you want it in blocks.
What is the Function of the CPU in plc?
1_ Updating the inputs and outputs. 2_ Perform logic and arithmetic operations. 3_ Communication with the memory. 4_ Scanning application programs. 5_ Communicating with a programming terminal.
Is a random access memory a input or output device or both?
Random Access Memory (RAM) is the volatile memory that is both an input and an output. You input data into the memory and can output the result on the monitor or print it out on paper, etc.
What would be the hexadecimal representation of the largest memory address in a memory consisting of 4MB if each cell had a one-byte capacity?
If the architecture allows each individual byte to be adressed then there are 4,000,000 possible addresses ranging from 0 to 3,999,999. So the largest address is 3,999,999 which is 3D08FF in hexadecimal representation
What is the bit capacity of a memory that has 1024 addresses and can store 8 bits at each address?
1024 bytes is 8192 bits.
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
Maximum RAM capacity of 8086 processor?
The 8086/8088 can address a maximum of 220, or 1,048,576, or 1 MB of memory.
What is the capacity of DRAM with twelve address lines?
Since DRAM uses address multiplexing(essentially each line accesses both columns and rows in memory) you need to take 2 to the 24th power to find your total capacity(basically doubling the number of address lines). In this case it would be 16,777,216.
How do you find memory capacity of PC?
to find the capacity, go to control panel and click on storage/memory
What is false about sensory memory?
