| INNOTECH SYSTEMS INC. Preliminary 12/15/00 IC1001 INFRARED RECEIVER/DECODER INTEGRATED CIRCUIT FEATURES C C C C C Integrated Solution Enables Computer or Microcontroller to Receive Infrared Remote Control Signals Converts Serial IR input from Handheld Remote Control to Parallel Data Words Matches Control ISI101B Handheld Remote RST XTAL2 XTAL1 Vss PIN CONFIGURATION D4 D3 D2 D1 D0 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 Vcc D5 DS IR IN Up to 64 Key Positions DESCRIPTION The Innotech Systems IC1001 Infrared Receiver/Decoder Integrated Circuit provides a convenient means of enabling microprocessor or microcontroller-based systems to receive infrared remote control signals. The ICI1001 receives and decodes the infrared signal generated by the matching ISI101B handheld "Customizable Universal Remote Control." The IC1001 inputs serial IR data from an infrared detector and provides a 6-bit parallel word indicating row and column location of the remote control key pressed. An Infrared Signal Detected strobe remains active as long as the key on the remote control is held down, and will remain active 75 ms after key release. The parallel bus data will remain latched until the subsequent key press. CODE DESCRIPTION The IC1001 and matching ISI101B Remote Control support keypad layouts of up to 61 keys. Unused keys on the matching remote control are "masked out" with an overlay template ensuring a unique look to each remote control design. The available remote control key locations and the matching hexadecimal codes produced by the IC1001 are shown below. 320 Main Street Port Jefferson NY 11777 (631) 473-1500 FAX (631) 473-5259 41 Winter Street Boston MA 02108 (617) 695-2700 (617) 423-0466 IC1001 Page 2 ! 04 09 0C 10 14 18 1C 20 24 28 2C 30 34 38 3C 05 09 0D 11 15 19 1D 21 25 29 2D 31 35 39 3D 06 0A 0E 12 16 1A 1E 22 26 2A 2E 32 36 3A 3E 03 07 0B 0F 13 17 1B 1F 23 27 2B 2F 33 37 3B 3F 8 Top Of Remote ISI101B Customizable Remote Control Illustration shows key locations of matching ISI101 "Customizable Standard" Remote Control and codes produced for each key location.
