DESCRIPTION

The IR117 is a state-of-the-art controller IC for handheld remote controls. Utilizing a precision, on-chip oscillator it needs no external crystal, resonator or other clock source. The IR117 includes internal pull-up resistors to eliminate even more compents that are needed for typical remote control ICs. In fact, a complete 32-key remote control can be constructed with just 8 components (excluding the keypad matrix and battery contacts).

The IR117 is a very low power, electrically quiet device dissipating just 500nW when waiting for keypresses. In this state, the on-chip oscillator is stopped to reduce noise and further reduce power consumption. When sending it dissipates just 450uW. This means extremely long battery life even when operating with small battery cells; for example: a pair of AAA cells.

The IR117 uses the RS-1TM infrared communications protocol to for long distance, accurate transmission of keypress information. A range of 10m indoors is achievable even with inexpensive driver transistors and IR emitters. The RS-1TM protocol has been designed to allow for over 65,000 unique manufacterer and/or product IDs. Other popular IR protocols as well as custom protocols are also available. Please call for details

Signal Description

SE0 through SE3 are keypad sense inputs. They are low-true. Each has an internal pull-up resistor in the range of approximately 20K ohms.

SC1, SC2, SC4 and SC5 are keyscan outputs. They are driven low while waiting for a keypress. When a keypress is detected, these outputs are cycled to detect which key has been pressed.

SC0 and SC3 are keyscan outputs and LED drivers. They are diven low while waiting for a keypress. They are cycled during keypress detection. During the IR output phase, these output drive an LED to indicate IR transmission.

SC6/BKL is a keyscan output and backlight driver. It is low while waiting for a keypress. It is cycled with the other keyscan signals to detect which key has been pressed. When not scanning keys, this output controls the optional backlight.

SC7/IR is a key a keyscan output and IR emitter driver. It is low while waiting for a keypress. It is cycled with other keyscan signals to detect which key has been pressed. After a keypress has been detected, this signal drives the IR emitter.
