This application note provides a reference for design with the Zilog IR controller and the UIR database. Various IR signals are compressed and encoded into Zilog's database format. A designer need not go through the entire database format, but simply call up a subroutine. IR data relating to the specific key for the appliance brand and the application device are retrieved and sent out. Zilog offers a wide range of infrared remote controllers. Low power Microcontroller Units (MCUs) are designed to support infrared remote control signals. Two hardware timers, T8 & T16, generate IR signals accurately without the software latency associated with turning the IR LED On/Off. P36 output supports the different logic operations of the T8 and T16 timers providing flexibility to support IR and RF applications. Table 1 lists Zilog's family of IR remote controllers.

Zilog controllers integrate most external components such as pull up resistors for key scanning and transistors for driving visible LEDs. Zilog also offers microcontrollers with input and output pins for most key matrices. P36 is the T8 and T16 timer output. By selecting the AND of these two timers and outputting the signal with the carrier at P36, this signal drives the transistor directly to switch the IR LED. P37 has a high current drive which directly controls the LED indicator. Port 2 is configured as input with internal pullup resistance. It is also the Stop Mode Recovery source which wakes up the microcontroller from a power-saving Stop mode. Port 0 is configured as open drain output, which is essential for key matrix design. For detailed UIR design considerations, refer to the application note "Universal Infrared Design." If comparators are not used, connect Pref1 to Vcc to avoid current leakage. Figure 1 Standard Zilog UIR Circuit Key Definition Key scanning is accomplished by using port 0 as open drain output and port 2 as input (with internal pull-up). Key scanning supports a 8 x 8 = 64 key matrix. Each key is defined AN004603-0604 AN004603-0604 ©2004 ZILOG, INC. 7 Universal Infrared Remote Reference Design as by its Column-Row address. The designer can change key locations to suit a PCB design easily. For example, key "TV" is defined as %74 in the KEYEQU.H file. The "7" is Port 2 bit 7 of and "4" is Port 0 bit 4. Just changing the KEYEQU.H header file rearranges the key location. Device keys are TV, VCR, CABLE, SAT, AMP, CD, and DVD. Rows P00 and P01 are used for Audio Amplifier keys. Refer to Table 2.

It uses approximately 3 Kbytes of the program memory. The driver can be customized to a specific application. The rest of the memory is used for the IR database. The irdata.s file is generated by the IR Tools after the designer selects the device brand and code number from the database. Table 3 lists all the files for UIR reference design.

This integration can reduce the number of external components required and assembly time. To minimize current consumption when pins connect to 0V, the internal pull-up is typically 200K ± 50% at 3V at room temperature. The resistance value can change with VCC and temperature variations. Therefore, the application design must be independent of resistance values. Refer to the Application Note "ZiLOG Universal Infrared Design" for a description of the effect of resistance and stray capactance on key scanning design. To avoid the effect of resistance variation, a pre-charge must be implemented on the port 2 bus before every line scan. Port 2 Pre-charge Procedure 1. 2. Set P2 as push-pull. 3. Set P2 as output. 4. Wait for 17 µseconds. 5. AN004603-0604 AN004603-0604 Write FFh to P0 and P2 (to set all outputs high). Set P2 as input. ©2004 ZILOG, INC. 12 Universal Infrared Remote Reference Design Programming Procedure 1. Change application device - 2. Press and release any device key (for example, TV, VCR, Cable) Change code (3-digit number of the code selected) - Release the device key. LED stays on. - Press and release 3 digit keys one by one. LED goes off when pressing a key and on when the key is released. - 3. Press and hold the device key for 3 seconds. LED comes on for 3 seconds and then turns off. LED flashes 3 times to indicate success after the 3 digits have been entered. It exits to the main program if a non-digit key is pressed or a code number is higher than the limit. Check code number - Press and release the SELECT key - 4. Press and hold the device key for 3 seconds. LED comes on for 3 seconds and off afterward the key is released. A flashing LED indicates the code number. A quick flash equals zero; a slow flash equals one. It will first display the factor of one hundred, stop for 2 seconds; secondly, the ten factor, go off for 2 seconds; and finally, the digit factor. Start Auto-scanning - Press and release thePOWER key. - Press Ch+ to search forward . The UIR sends out POWER signal for the next higher code number. - Press Ch- to search downward. The UIR sends out POWER signal for the next lower code number. - Press the SELECT key to store the correct code. - AN004603-0604 AN004603-0604 Press and hold the device key for 3 seconds. The LED comes on for 3 seconds, then goes off. The LED flashes 3 times if the code is stored. If the LED flashes rapidly 8 times, the code search is finished or the beginning code number must be re-entered. ©2004 ZILOG, INC. 13 Universal Infrared Remote Reference Design Results of Operation The LED indicator on the remote control guides the user through programming, verifying and sending the IR signal. After programming the correct code number, the remote control can control one or more application devices (TV, VCR, cable, Sat, Amp, CD, etc.) The LED indicator stays on as long as the signal is transmitting. For example, to program the remote control for a SONY TV, first find the code number (272) from the code list table. Follow the "Change Code" programming procedure to change the code: press and hold the TV key for 3 seconds. Release the key after the LED flashes. Enter the digits "2", "7", "2" one by one. After the remote reads all three digits, the LED will go off after accepting the programmed code. It will flash 3 times to indicate an invalid code number. Point the remote control at the SONY TV, then press the POWER key to turn on the TV. Summary Several field tests were conducted in shopping malls with the display devices.
