 I have included two circuits here:-
  1. 89SXX ISP Programmer using RS232 Interface.
  2. 89SXX ISP Programmer using USB interfacing.
            Fig. 1 shows the Schematic of Programmer with RS232 interface.
The above circuit uses RS232 for interfacing with PC. It is very simple circuit & works very well with PC.Power is drawn from usb port OR needs external supply of 5V.
The value of the crystal is very critical at AT89C2051 and must be 11.0592MHz .Here AT89C2051 is loaded with firmware required for RS232 communication with PC. Assemble the circuit and burn the firmware into an AT89C2051 (you will need a conventional parallel Programmer to Program the AT89C2051).Use the 40 pin ZIF socket for microcontroller.The firmware(.HEX) file is in the Software folder. All the required documents and Files are attatched.

1)     Don’t panic if computer is not able to detect kit Please check all the connections on the board. While designing circuit manage to make jumper-less circuit.
2)       Before connecting it to PC check if any paths are shorted to another.
3)       Verify if the firmware is burned appropriately or not.
4)      Check voltage level at the two pins of the crystals it should be approx. 0.7 - 0.27V.     When you run the software for the first time it looks for a valid programmer on COM1. If the Programmer is connected to say COM2 you will receive an error message but when the application starts select Options->Settings on the Menu and specify the correct COM Port.
6)      Check RS232 cable. Check continuity of every pin.

Fig. 2 shows the Schematic of Programmer with USB interface.

In this circuit power is drawn from usb port itself, so no need of external power supply. Led at the bottom is connected to p2.7 for testing can write program to turn on & off the led.led is connected in sinking mode.FT232 is an SMD , its on the bottom side of the board so you can see only 2 ICs in the above circuit.

1)      Once you are done with USB circuit.Connect the circuit to Computer.
2)      Download Virtual COM Port (VCP) drivers for FT232RL from
3)      For installation Guide of VCP Drivers open “VCP Drivers installation Guide.pdf”
4)      After Device Drivers Installation go to
Control Panel\Hardware and Sound\Device Drivers\

After this step open ISP Programmer and configure the COM#  port in “Option>Settings>”

Component List for usb programmer

 Note:Purchase 8051 of S series only (89's'XX)-40pins DIP 

If you are purchasing components from Mumbai(Lamington Road.) you can program 89C2051 (firmware IC) from VishaKits near GALA.

I have attached PCB layout (for USB only) & related softwares.

Here is a low cost, wireless switch controller. It uses ultrasonic sound waves for remote control of a switch. As with any other remote control, the system basically comprises a transmitter and a receiver circuit. Frequencies up to 20kHz are audible. Frequencies above 20kHz are not audible. The transmitter circuit generates an ultrasonic frequency between 40-50kHz. The receiver senses the ultrasonic sound and switches on a relay. The transmitter uses a 555 astable multivibrator. It oscillates at a frequency of 40-50kHz. An
ultrasonic transducer is used to transmit the frequency. The transmitter runs on a 9v battery. The ultrasonic receiver uses a receiver transducer to sense ultrasonic signals. It uses a twostage amplifier, a rectifier stage and an operational amplifier in inverting mode. Output of the operational amplifier is connected to a relay through a driver stage. A 9v adapter can be used to power the receiver circuit. When switch S1 is pressed, it generates ultrasonic sound. The receiver amplifies the received signal via transistors Q3 and Q4. The amplified signal are then rectified and filtered. The filtered DC voltage is given to the inverting pin of operational amplifier 1C2. The non-inverting pin of 1C2 is connected to a DC voltage through VR2 that determines the threshold value of the signal received, for operation of relay RL1. The inverted output of 1C2
is used to bias transistor Q5. When transistor Q5 conducts, it supplies base bias to transistor Q6. When transistor Q6 conducts, it energises the relay RL1 . The relay can be used to control any electrical or electronic appliance. Frequency of the circuit can be varied by adjusting VR1. Adjust it for maximum performance. Ultrasonic sounds are highly directional. So when you are using the transmitter, the receiver should face towards the transmitter. The receiver is always kept on.
The transmitter circuit can be simplified to the following design as the driver transistors are not
needed. They do nothing.
