Document: Datasheet Date: 28-Feb-12 Model #: 3617 Product’s Page: .sunrom./p-963.html - Infrared remote control decoder RC5 The main function of the ST3617 is to decode the RC5 data received from remote control into 16 bit serial data output. There are two ways of getting data from chip, Data of 9600 baud rate or Serial Shift of data through RDY, CLK and DAT pins. Many remote control applications can be developed using the decoder. Block Diagram ST3617 needs only one ponent to work that is IR receiver like TSOP1738 or similar. The data is output as simple 2 bytes of serial data consisting of 16 bits of information for each key press on the remote. Specification Parameter Value Working Voltage Current 3-5V DC 10m A Serial UART Interface 9600 bps, 8 bit data, no parity, 1 stop bit at 5V or 3V level Serial Shift Interface Uses three pins RDY, CLK and DAT to output decoded RC5 data ST3617 is a Microchip PIC Controller that is programmed by us and labeled to work as per details in this datasheet. Pin Details 1-VDD 2-IR 3-TXD 4-N/C 8-GND 7-DAT 6-CLK 5-RDY Pin# Pin Name Type Notes N/C Supply Input Output Not Used Output Input Output Ground 3 to 5V DC regulated power supply input Connect IR receiver output to this pin Outputs serial UART data at 9600 bps at TTL level Not Connected, This pin is not used and should be left unconnected Ready Signal Output of Serial Shift Interface Clock Input of Serial Shift Interface Data Output of Serial Shift Interface Power Supply Ground Data Interface for ST3617 RC5 Decoder There are two ways you can get the output from ST3617. For each output the data is two bytes long containing total 16 bits RC5 data. Two types of Interface for reading RC5 data from ST3617 U3 TSOP1738 Interface #1 is Serial Shift Interface, which consist of three pins. In this interface you have +5V to monitor...
