PIN CONFIGURATION
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.
