Is adc present on chip in 8051 or not?
There is no formal adc input on the 8051. However, the CMOS version of the chip can use a technique involving a resistor, diode, and capacitor, along with a bidirectional pin (or one output pin and one input pin) to implement a "quick and dirty" adc function. You discharge the capacitor and then let it charge to the voltage of the input. You measure the time it takes to see the input pin change, and you calculate the input voltage.
How do you connect a motor to a picaxe 18M?
It depends. If you only want to turn the motor in one direction, then you could simply use a medium power mosfet (eg:IRF530) connected to an output pin on the PICAXE, and with a backward diode around the motor. If you need to change direction, it's best to use an L293D, which allows independent bidirectional control of two motors.
Explain about pin diagram of 8051 micro controller?
The microcontrollers have an 8-bit data bus. They are capable of addressing 64K of program memory and a separate 64K of data memory. The 8051 has 4K of code memory implemented as on-chip Read Only Memory (ROM). The 8051 has 128 bytes of internal Random Access Memory (RAM). The 8051 has two timer/counters, a serial port, 4 general purpose parallel input/output ports, and interrupt control logic with five sources of interrupts. Besides internal RAM, the 8051 has various Special Function Registers (SFR), which are the control and data registers for on-chip facilities. The SFRs also include the accumulator, the B register, and the Program Status Word (PSW), which contains the CPU flags. << SHARMILA TANDEL (B.E) ELECTRONICS >>
What is the difference between 8086 and 8088 microprocessor regarding there pin diagram?
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)

How do you identify pin connections on AND gate IC chips?
To identify pin connections on an AND gate IC chip, refer to the datasheet provided by the manufacturer. The datasheet will have a pinout diagram showing the location and function of each pin on the chip. Additionally, you can use a multimeter to test for continuity between pins to confirm their connections.
What are the pin limitations of VLSI Integrated circuits?
In the Chip design flow to estimate the Chip Die size (means area ) how much is needed , could be pad limited or core-limited. After performing the padring of the chip(arranging of pads/pins), the scenario is such that the core area(logic area) is less then the die or chip is called as pad limited or pin limited design whereas if the core area or logic area of the chip is more than the pad area then the die-size of the chip is core-limited.

What are chip and pin machines used for?
The simplest system - is on your ATM card. When you insert your card into an ATM - the system reads the data stored on the chip. It then matches that data with the central computer - so it knows what PIN should be entered. If you enter the correct PIN, you can proceed to withdraw cash - if the PIN is wrong - you get another two attempts, before the machine retains your card. Using a chip & PIN card in a shop to buy goods - the system is the same as an ATM. The difference is - if you fail to enter the correct PIN three times, the system simply disables your card - and you have to order a new one !
What is the maximum number of inputs you could have on say an OR gate If it were a 16 pin chip could you have 14 pin inputs one Vcc and on GND?
You need an output pin as well, so in the example of the 16 pin chip, you could have 13 inputs.

Are chip and pin credit cards widely accepted in the USA?
Yes, chip and PIN credit cards are widely accepted in the USA, but they are not as common as chip and signature cards. Many merchants in the USA have upgraded their payment terminals to accept chip cards for added security.
