Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to PT2272. It is a CMOS (complementary metal-oxide-semiconductor) that use to design simple wireless controlling of instruments installed at some distance. This module is normally used for controlling the circuits of garage door, speed control of the fan, robots and for monitoring the alarm connected at different places for security purposes. This integrated circuitry uses non-variable code address and no built-in encryption due to these parameters it not used for such circuits where high security is need but uses only for small or less cost security circuits such as used in home security alarms etc. In today's post, we will have a look at its working, pinout,  applications and some other related parameters. So let's get started with the Introduction to PT2272.

Introduction to PT2272

  • The PT2272 is a decoder coupled with the PT2262 use the complementary metal-oxide-semiconductor technique.
  • The use of PT2262 with this module to work as a transmitter for the PT2272 that work as a receiver and decodes the data sent by the transmitter.
  • The output pinouts of this module are transistor-transistor logic that can be connected with the other circuitry and microcontroller.
  • The operating voltage of the transmitter (PT2262) is five volts to twelve volts dc and the operation voltage of PT2272 are also five volts dc.
  • This module consists of twelve bits of tri-state address pinout that offers three hundred twelve address codes.
  • This module has features like large no of output data pinouts, latching and temporary output.
  • The complementary metal-oxide-semiconductor technique (CMOS) technique used in this module offered the use of less power, less sound to noise ratio, twelve tri-state address pinouts, six data pinouts many ranges of voltages operation.
  • This integrated circuitry is the finest option for security circuits used in different vehicles like cars, door alarm, robotic controls and some other home automation circuits.

Pinouts of PT2272

  • Now we discuss the pinouts of PT2272 with the detailed, that is described here with the detail.
Pin No: Pin Name:                                         Parameters
A0 to A5 Input pinout These pinouts are address pinouts. All these six pinouts are used to get input coming from the transmitter and then encode the data.
A6/D5 ~ A11/D0 Input and output pinouts These 6 pinouts are used for such data that has a large number of bits and also on the type of PT2272 module used.
DIN Input pinout When these pinouts are operating as inputs, these pins behave as tri-state input pinouts and every pin can set at the three different levels one, zero and floating. If we use these six pinouts as When used as output pins, these pins are driven to VCC if (1) the address decoded from the waveform that was received matches the address setting at the address input pins, and (2) the corresponding data bits received is a “1” bit. Otherwise, they are driven to VSS.
OSC 1 input pinout It is oscillator pinout no one.
OSC 2 Output pinout It is oscillator pinout number two. A specific value of resistance connected among them finds the value of the fundamental frequency of PT2272.
VT Output This pinout is used for the output gain
VCC - At this terminal positive input is provided.
VSS - This terminal is used to provide a negative supply.
NC - This is open pinout.
