HT9200B Datasheet PDF

I think what you want is an Dayasheet that takes something the arduino can talk to easily, like serial, i2c, etc.

As for the control timing diagram, see Figure 2. Additional supplementary information with regard to packaging is listed below. I am currently building a burglar alarm with 2 PIR sensors from sparkfun. I don’t think this is the ideal IC for your purpose, because it’s set up to receive inputs from a key numeric pad.

I have these th9200b so on to my next problem. Ah, I took another look at the datasheet and you’re right. As for the control timing diagram, refer to Figure 1. Actually, I think it may be a little complex to use serial mode after viewing this document.

As this information may be updated at regular intervals users are reminded to datxsheet the Holtek website for the latest version of the package information. It has a serial and a paralell interface. Then the input data codes should be determined. The oscillator function can be implemented by Connect a standard 3. Thanks for any insight.

Below is a datasheet for my IC and I have spent many hours trying to get this to ht99200b Every digit of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data.

He recommends Holtek B. However, Holtek assumes no responsibility arising from the use of the specifications described. I know I’ve seen threads from other people trying to interface Arduino to DTMF, maybe there’s a solution out there that you could adapt. I think the serial interface would suit perfectly with the arduino but I may be wrong.

Would I just connect the data pin of the IC to the pin 1 of my arduino to send the serial data to it? Read times previous topic – next topic. I promise to post start a build log for my alarm as soon as I know I can do it The applications mentioned herein are used solely for the purpose of illustration and Holtek makes no warranty or representation that such applications will be suitable without further modification, nor recommends the use of its products for application that may present a risk to human life due to malfunction or otherwise.

Click on the relevant section to be transferred to the relevant website page. Both modes produce the same basic tone pairs for digital dialing, corresponding to the keys: When the IC is operating in the serial mode, this pin becomes floating. I’d really appreciate your help on this. Dimensions in mm Min.

X Y Pad No. Here is some code I wrote for that chip. Hi Guys, I just received my Arduino in the post a few days ago and have been having great fun with it. These are stress ratings only. I’m probably doing everything wrong as I am more of a programmer than electronic eng. Thanks datasheey advance for any help.


Holtek reserves the right to alter its products without prior notification. For the most ht900b information, please visit our web site at datashret I have searched the internet far and wide for the past few days and I have come up blank. To nt9200b it to work, you’ll have to get the arduino to mimic the electrical behavior caused by the capacitance change that happens when you press one of those buttons.

The relationship between the digital codes and the tone output frequency is shown in Table 1. Thus, these data input pins should not float.

When the IC is operating in the parallel mode, these pins become floating. The information appearing in this Data Sheet is believed to be accurate at the time of publication. The relationship between the digital codes and the tone output frequency is illustrated in Table 2. Still no tutorials however.
