SM6136B Transmitter (?) seen in a Toy Car Remote

sm6136b

Today I saw SM6136B IC inside the remote of a toy car. I guess that toy is made in China. I tried to see the information about this chip on net, but could not get anything which will show how to use this IC.

In fact I want a cheapest Transmitter/Receiver IC/Module in India. Can anybody suggest any?

TIA,

That is a five key encode IC for remote car toy.

Yes. I checked the circuit, it seems to be encoder only.

Now my question is, Can I interface the same circuits (transmitter and receiver) to microcontroller instead of encoder/decoder? If yes, how and where do i connect them? TX /RX?? or I/O lines? Please give me the link or any info if possible.

You can use u'C i/o transmit & receive bit-shift-data by OOK modulation.
Because SM6136 is a encode(or deode) OOK modulation data by pulse length & pulse count.

ic sm6136b

hey!....this is jack..
i can give the information about this chip....don't worry...
the sm6136B is an encoder chip commonly found in toy remote cars...
these encoders transmit the data to the reciever.....by using frequency matching
technique the main thing about this encoder chip is that each time when you press a key it encoder the four bit code....just like this...
for example you have the four keys...1,2,3,4
if you press the key 2 it encodes the data like this...
0010
pressing key1
0001
pressing key 3
0011
pressing key 4
0100
this encoded data is transmitted using a transmitter
at first this encoded data is modulated and it is synchronized by the clock pulses..
and transmitted through the antenna....
whenever this transmitted data is recived at the recieving end the modulated wave is passed through a demodulator(this process is called demodulation...which is the reverse process of modulation...)and this modulated wave which is arrived at the
receiver is demodulated by passing the modulated wave and the synchronized clock pulses (which have the same frequency matches with transmitter frequency) through the demodulator and the output of the demodulator is fed to the decoder
chip it receives the data serially and decodes the data parallelly...
i have sent the pin diagram of sm6136b transmitter and the sm6135b reciver chips// you should see this....

i have sent an word document so valuable.......
you should see this......
it contains all the functions of each pin of the transmitter chip...sm6136b..
and also the receiver sm6135b..okay...!!!.....

sm6136b english datasheet

Well... I would like to see the the circuit with the RF circuit. Could anyone here share me the RF circuit (RF section) ?
Thank you for your sharing !

sm6135b схема

The datasheet for the encoder IC is written in Chinese so I couldn't see if it has an RF transmitter circuit.

The encoder is a very cheap and simple BANG, BANG one without proportional control like model RC circuits have.

ic sm6135w

So this is BANG,BANG chip?
Oh my God this is very dengerus chip.

sm6135w circuit diagram

BANG, BANG control means suddenly full speed or stop. Turning suddenly extremely to the left, straight or extremely to the right.
It would be very dangerous in a real car.

Proportional control like models have is as much speed or amount of turning that you want. Like a real car.

datasheet of sm6136b

Where can i get the datasheet of SM6135W??

sm6136b circuit

The IC is Chinese. Datasheetarchive has the datasheet but you must download 20MB of Chinese fonts to read it in Chinese. **broken link removed**

receiver ic for sm6136b

Can somebody phelp me.. i wanna build a rc car with atmega32 with SM6135W,SM6136B as tramsmitter and receiver. I dunno how to work with the transmitter and receiver alongside the atmega32.

sm6135w rf

hi..
it was great to find help regarding sm6136. at last i found it here after a long search of datasheets!!!
could anyone pls help me with the receiver details of bf110514??

receiver (sm6135w chip)

Friend I wanted to see the circuit diagram for the reciever circuit using the ic sm6135w. So can anyone please help me out.

Hai Shetye
Instead of strugling to get the info regarding a chip which is not openly available, my humble sugession is that you may construct a simple 4 channel RF remote with HT12E and D chips which are available in open marker for arroung 50/- in India. The application schematic is attched here. Also a ready to assemble OR assembled Kit for the same is available for 1550/- Rupees from www.united77.com/projects.htm
Good luck

Does anybody have IC's model which can be imported into simulation softwares? Thx a lot !!!

Hi Gears,

Thanx for your information..... it really cleared all of my doubts regarding sm6136b....

thanx alot

Hi,
Can you please tell me... How can we increase the range of communication (by distance) of sm6135 / sm6136.... At present itz working within the range about 8 to 10 meters only.... I wish to increase its range upto 50 meters .... Can you please tell me, what should i do for this.......???

Waiting for an early reply......
